Synthetic resin namely high polymer material is traffic of car, building, orbit and new generation IT, biology, high end equipment is made, new energy resources, aerospace strategical the material of important form a complete set that burgeoning estate development is badly in need of and important safeguard, be development of science and technology and social progress is important prop up. Hundred years those who have no is big change bureau quicken gradual progress, new revolution of round of science and technology and industry change to go forward one by one continuously, industrial catenary supplies catenary to reframe to be being quickened, high polymer material and its technology more and more the central point that makes international competition.
Come ten years, our country occupies the position of petrifaction big country firmly all the time, the world of chemical sale is occupied than prep above 40% , the global consequence of the market is highlighted increasingly, high polymer material regards scope also is first place of certain room world, but high-powered colophony and high-end material are short all the time board with weak sports. Incorporate is general synthesis material, general synthetic resin (be like 5 big general and plastic reach polyester) be in excess position; And high-powered data, if 5 big projects are plastic (PC, POM, PA, PBT, PPO) with special type project plastic (PPS, PI, PSF, PES, PEEK) , carbon fiber of fragrant black silk ribbon basically counts an import the high-powered fiber such as high-grade nylon and high-powered film stuff, individual high-end product the moment of truth returns existence “ to block neck ” problem.
Ask: Current situation of our country synthetic resin how?
At the beginning of 20 centuries, american chemist synthesized phenolic aldehyde colophony artificially, open those who synthesize high polymer material is prelusive. Later in succession synthetic rubber of success of research and development, nylon - 66, get together methylic acrylic acid material of a variety of synthetic high polymer such as armour ester, polystyrene, pvc; 20 centuries 50 time, ziegler - the innovation of accept tower activator and application, realized ethylene to often control next directional group in normal temperature, craft of this kind of activator cost of simple, production is low, make polyolefin fast industrialization and large change, quickened high polymer to synthesize the development of data industry, high polymer material is a foundation with general synthesis material.
According to the statistic of world plastic Manufacturers Association, 51% what the Asia's plastic crop holds global total output, north America is occupied 19% , the European Union is occupied 16% , other area is occupied 14% . According to forecasting 2015~2025 10 years plastic consumption will increase a whole world 50% , will see plastic production and consumption nearly 10 years add with respect to the whole world fast exceed any material. See the value of plastic industry, also be the industry with dye-in-the-wood latent capacity of a development.
The yield of Chinese synthetic resin can crop and consumption come to the first reside the world firmly all the time for years. Mix according to national statistic bureau newest " produce can early-warning reports " data shows, 2022, synthetic resin crop is close to 114 million tons, the entrance measures 29.58 million tons, apparent consumption 130 million tons. Among them, polyethylene is produced can 29.81 million tons / year, crop twenty-six million three hundred and sixteen thousand tons, the entrance measures thirteen million four hundred and sixty-seven thousand tons, apparent consumption thirty-eight million and sixty-one thousand tons; Polypropylene is produced can 34.96 million tons / year, crop twenty-nine million six hundred and fifty-five thousand tons, the entrance measures 4.511 million tons, apparent consumption thirty-two million eight hundred and nine thousand tons; Polyvinyl chloride is produced can 26.42 million tons / year, crop 21.97 million tons, the entrance measures 362 thousand tons, apparent consumption twenty million three hundred and sixty-seven thousand tons. Polystyrene is produced can 5.25 million tons / year, crop 3.55 million tons, the entrance measures 889 thousand tons, apparent consumption 4.321 million tons; ABS is produced can 5.255 million tons / year, crop 4.31 million tons, the entrance measures 1.37 million tons, apparent consumption 5.599 million tons; Polycarbonate is produced can 3.2 million tons / year, crop 1.78 million tons, the entrance measures 1.386 million tons, apparent consumption 2.5 million tons; EVA is produced can 2.15 million tons / year, crop 1.738 million tons, the entrance measures 1.202 million tons, apparent consumption 2.824 million tons; 66 section produce nylon can 6.11 million tons / year, crop 4.273 million tons, the entrance measures 199 thousand tons, apparent consumption 4.09 million tons; Luxuriant metal polyolefin is produced can 2.2 million tons / year, crop 300 thousand tons, the entrance measures 2.1 million tons, apparent consumption 2.4 million tons.
2 ask: After plastic industry has taken hundred years course, a what new trend does industry of current synthetic resin present?
The first, the tide that upriver raw material turns gently character. This one trend is initiated by North America and thalassic area, since 935 ” of “ fast Xiang Ou, inferior wait for main economy system to advance. Its model is represented is make alkene for raw material with light hydrocarbon, namely propane dehydrogenation makes propylene and ethane splitting decomposition make ethylene, its representing area is North America, bay and northeast inferior China. Shale of North America profit from enrages revolutionary success, shaly gas contains a lot ofthe ethane in light hydrocarbon, classics splitting decomposition makes ethylene after ethane is detached, compare with photograph of traditional craft of naphtha splitting decomposition, flow lowest of the shortest, cost, also be the cleanest craft; Associated gas of oil of thalassic area profit from is resourceful, after many ethane and propane classics are detached, make via splitting decomposition and dehydrogenation respectively take ethylene and propylene, compare its competition ability with photograph of traditional naphtha splitting decomposition more get the better of one prepare. So of global olefin raw material change transition gently nearly 10 years to appear character quicken posture, to 2020 the world is occupied for the ethylene of raw material with light hydrocarbon always produce can 53.5% , among them ethane splitting decomposition is occupied 40.3% .
China is seasonable also trend of this one transition mixes follow-up pace, ethane splitting decomposition makes ethylene also be paid close attention to by numerous home company, include plan to build with extend category. But later because of resource gift restrict, the oil in having only cling to 2 suit buy includes city He Changqing pilot set an example, chemistry of the in having only oil that already built go into operation at present, new riverside, 10 thousand China the 7 suit buy such as petrifaction of chemical, satellite, with ethane or mix light hydrocarbon to make ethylene for raw material, produce can 6.18 million tons / year, produce can occupy our country ethylene to always be produced about can 13.2% . The light hydrocarbon such as propane makes propylene device be built quickly for raw material dehydrogenation, already built propane and C? C? Mix light hydrocarbon to make propylene device 34, add up to produce can sixteen million and twenty-six thousand tons / year, occupy our country propylene to always be produced can 34.9% , there are 8 in the 17 propylene device of put into production 2022 among them, took new last year increase production can 6.01 million tons / year 62% above; Go into operation builds again since this year device of 4 propane dehydrogenation, new increase production can 2.52 million tons / year.
Overall look, domestic olefin raw material changes transition gently to already got the height of industry colleague pays close attention to character. Prove light hydrocarbon origin and the premise that supply catenary safety and economic competition ability to fall in science next, OK still and discreet decision-making the alkene plant construction that is raw material with light hydrocarbon.
The 2nd trend is current data is high-powered change. Do not exist between current data and high-powered data completely boundary. These general synthesis material such as polyethylene, polypropylene, pvc also can pass modified and alloy to change implementation high end is changed and high-powered change, after these average synthesis data pass modified, its performance characteristics is in certain applying the domain can replace the nylon, project such as polyformaldehyde plastic. Polyvinyl chloride can make floor of high-end copy real wood be exported in great quantities not only through modified, and still can apply at the high end such as Gao Tie to make after functional sex modified. A little common polyolefin uses new activator and aggregate technology, its product function and applied domain can realize high end to change, luxuriant metal polyolefin is typical delegate, the elastomer of luxuriant metal group can replace polyurethane new material not only, also can replace certain project plastic. New coronal vaccine needs wrapping paper of a kind of special type to call “ to defend strong ” especially during epidemic situation, it is the packing film of make it of material of a kind of chemical industry, say this film that pack has Du Bang company to be able to be produced only at that time, ask to you can be found inside our country at that time? I consulted Dean Liang Aimin assistant of academy of Beijing chemical industry later, he says: “ this is the material of high density polyethylene that permeates a kind of high strenth, high, become extremely thin fiber in the gush below high temperature above all, classics is multilayer the composite material that bind becomes low pink broken bits. This kind of material fights glycol, alcohol to wait destroy vivid agent, fully water, but do not appear the macromolecule such as protein, have only really prevent nation production. ”
The function that the 3rd trend is synthetic material is changed. The function that material synthesizes since new century is changed is the key of developed country and transnational corporation innovation and strategic transition. Be like car bumper from repair material, small capsule was added in existing PU material, once touch,crack small capsule to restore to be like with respect to proper motion rehabilitate, bumper first. The new material of medical and organic silicon of made of baked clay gram is used at achieving to be able to be stuck, breathe freely, not easy heal of adhesion, cut, electric car indication screen improves the indication result below strong smooth illuminate greatly with new material of organic silicon modified. Ever hair of reportorial California university understands a kind of new-style polymer that has self-healing function, be a kind but the new material that drawing polymer and ionic salt make, can use at smartphone screen and batteries. Still division collect of reportorial United States pulls much university to excogitate a kind to need not make cryogen, need not electric power can drop in temperature for the building, cooling effect strong, cost drops in temperature lowly filmy material, every square metre makes an appointment with 50 cent. The trade name TPX of this kind of transparent film, treatment becomes about 50 micron thick, the housetop laid of an average house 20 smooth rice this kind is filmy, when the temperature outdoor when 37 ℃ , indoor temperature can maintain in 20 ℃ .
3 ask: The delegate of powerful nation of since of chemical new material, it is the focus that big country competes, current situation of new material of our country chemical industry how?
Chemical new material namely high-powered data with the project stuff of film of plastic, high-powered fiber, high end is project of plastic, special type delegate, basically include high-end polyolefin, project synthetic rubber of material of plastic, polyurethane, fluorine silicon material, special type and thermoplastic makings of base material of chemical of stuff of film of sex of elastomer, high-powered fiber and its composite material, function, electron, biology. High-powered data and high-end colophony call chemical industry new material commonly, as taller than having technical doorsill as current data phase, function sex of exceedingly good, function is strong, add be worth advanced characteristic, the central point that also makes play chess of big country rich and the heat domain that area competes.
Talk about the apparent progress that in recent years development of innovation of chemical new material obtains above all. Since 935 ” of “ , new material of our country chemical industry obtains a breakthrough on technology and industrialization in succession, ability of own form a complete set promotes continuously. According to petrifaction federation new material only appoint meeting statistic, new material of our country chemical industry was produced 2022 can achieve 45 million tons / year, crop makes an appointment with 33.23 million tons, sales revenue prep above 1.3 trillion yuan, consumption makes an appointment with 41.36 million tons, self-sufficient rate is amounted to 80.3% .
The technology breaks through and the representative product of implementation industrialization has: Polypropylene of the colophony of polyethylene of freeboard element quantity in high-end polyolefin, luxuriant metal, smooth hot season is used and tall frit shows He Li batteries of colophony of EVA of hot frit glue and biaxial stretching is diaphragmatic with reach high flow, Gao Kangchong, low volatilize wait for polyolefin; The project gets together plasticly carbon, PMMA, get together benzene aether, nylon 12 etc; Special type project gets together plasticly benzene sulfur aether, get together acyl inferior amine, get together ether aether ketone, get together the breaks through for a long time hard product on the technology such as ether sulphone; Carbon fiber, get together acyl inferior fiber of amine fiber, PE of freeboard element quantity, get together a few big high-powered fiber such as fiber of benzene sulfur aether and its composite material obtain breakthrough and industrialization ······ to be listed one by one no longer in succession.
Actually, we see domain of new material of our country chemical industry still is put in apparent difference even. Chemical new material still is industry of our country petrifaction from beginning to end is short board, still many products count an import, like the project the overall and self-sufficient rate of stuff of film of sex of plastic, function and electronic chemical is close to 80% , and self-sufficient rate is less than high-end polyolefin, high-powered fibrous however 60% , the self-sufficient rate of the high-end product such as glue of liquid crystal indication material, photoetching is lower have 5%-6% only. Especially general colophony gives priority to polyolefin, phyletic and coessential change, model is coessential change serious, high end is changed, poor dissimilation, special model be not worth badly with functional sex; The technology with special type plastic project is restricted more serious, the project is changed, industrialization difference is apparent, in low end the product is in the majority, high-powered product is in short supply. The freeboard in electronic chemical exceeds pure photoetching glue, high pure phosphorous alkyl and material of mat of high accuracy polish count an import for a long time, other still balata of high-powered fluorine colophony, fluorine waits also is to count an import badly. Another kind resembles ɑ of luxuriant metal activator, tall carbon namely - the crucial monomer such as 2 nitrile and material break through alkene, oneself for a long time hard, blood is dialytic etc medical stuff of film of high-end function sex also is long-term break through hard.
4 ask: Where is the stress that innovation of future of chemical new material develops?
Should be key breakthrough. The key is changed in high end during 945 ” of “ , breakthrough of poor dissimilation innovation, significant progress is obtained on industrial structure, self-sufficient rate exceeds whole of chemical new material 75% , produce can layout more hasten is reasonable, garden area is changed, intensive changes development level to promote further, form 10 or so production value to exceed garden of one billion four hundred and ten million and sixty-five thousand four hundred and eight yuan industry of chemical new material; Company structure obtains significant progress, breed a batch to resemble 10 thousand China mix chemically, newly, Dong Yue, peaceful and new material, Hua Feng, gigantic change, fair science and technology have the chemical new material that leads action to get army enterprise; Innovation ability increases significantly, own innovation and primitive innovation ability promote apparently, produce learn to grind to innovate in coordination the system becomes better day by day, build a batch of conditions and team world's top-ranking innovation platform; The key breaks through a batch of “ to block technology of core of neck ” key, race to control commanding elevation of innovation of a batch of science and technology, seriation of breed of chemical new material, high end is changed, poor dissimilation obtains apparent effect.
Answer at present focusing is in the product with more apparent difference. If luxuriant metal is high-end polyolefin, long,carbolic catenary nylon is mixed olefin of nylon of scent a group of things with common features, EVA, EVOH, α- , POE.
EVOH is filmy its cut off performance is superior, especially wet function of block oxygen block, its cut off performance is about a hundred times higher than nylon film, than polyethylene polypropylene thin coating is on 10 thousand times more expensive, than commonly used PVDC the film that pack is counted high also decuple, what EVOH film uses at bishop and milk is contain to pack to them with respect to understanding when I visit chemistry of 3 water chestnut.
EVA film encloses function, good ageing resistance exceedingly goodly to be able to be mixed because of its the price is low, it is at present the solar battery is enclosed with the most general glue film, took the half of country of market of smooth hot season, and the EVA of content of ethylene of our country tall acetic acid suffers a technology to restrict serious inadequacy.
Because,these a few kinds of products are technical bottleneck have not large-scale industrialization, and high-end product in short supply, the yield that although draft,plans can be very big, but have a technology oneself large-scale industrialization still needs to tackle key problem.
Batteries of ion of electric car lithium suffers with diaphragmatic raw material be restricted to highlight, because lithium report is diaphragmatic not only technical threshold is high, and safe safeguard demand is higher, if diaphragmatic damaged causes batteries short circuit, appear easily grave accident causes the loss that redeems hard. The main material with lithium at present diaphragmatic report is polyethylene, polypropylene, cent of the process that make film is wet craft and dry method craft. Doing law craft to use raw material is all polypropylene is occupied 96% , fight strong copolymerization polypropylene to occupy 4% , and wet craft uses raw material is to exceed high polymer to measure polyethylene to occupy 98% , high density polyethylene is occupied 2% . Because of be far ahead of whole world of car of our country new energy resources, so diaphragmatic our country also takes lithium report the 40% above of world market (Han 28% , day 21% , beautiful 6% etc) . Dan Li report is diaphragmatic basically give priority to with entrance makings with raw material, do because of homebred polyolefin base velar permeability is fluctuant quality of big, product is not stable, home is at present diaphragmatic with raw material cost taller. Grinding at present the new material of hair is diaphragmatic have get together slant fluorine ethylene, Wei Fangguan, PET, get together acyl inferior amine.
5 ask: Content radical and biology are born since a paragraph of period but degradation material is paid close attention to by the height of international home, ban oneself even (be restricted) since model policy comes on stage, biology but degradation data appears for a time overheat phenomenon, biology radical and biology but degradation material current situation how?
Biology radical and but degradation material is in recent years the whole world takes the key with research and development seriously, the area with developed country and the resourceful biology such as the United States, Germany, Japan, England, Holand, Brazil, the research and development that take seriously highly and accelerates makings of biology base material, industrialization and application. Current production petrochemical and material are being accelerated it is raw material to pledge to biology resource is raw material transition by the fossil resource such as coal of oil natural gas, the process that produces petrochemical and material to biology technology transition.
Forecast according to OECD, the petrochemical that will not 10 years have 20% above at least but by biology base the product is replaced, and current substitution rate is less than 5% , breach restrains 600 billion dollar; To 2030 global biology base chemical product is occupied achieve than hopeful 35% .
The United States " route chart of raw material technology " put forward: Biology radical chemical will replace 25% organic chemistry to taste 2030 with the oil fuel of 20% .
European Union " far seeing plan of industrial biology technology " also forecast: The careful chemical of the industrial chemicals that biology radical raw material will replace 6%-12% 2030, 30%-60% will by biology base obtain.
Association of European plastic industry expresses recently, biology of 2022 whole worlds base plastic crop amounts to 1.9 million tons, among them epoxy resin occupies biology radical 27% , biology radical polyethylene and get together lactic acid is 16% , biology radical polyamide is occupied 9% . European Union biology radical is plastic last year crop 400 thousand tons, in light of product structure: Biology polypropylene takes European Union live thing 24% of plastic crop, biology radical polyethylene is occupied 18% , PBAT is occupied 15% , epoxy resin occupies biology radical 9% .
Visible, biology radical and can take seriously what degradation material gets international home really highly, multinomial technology and breakthrough of many products innovation are being quickened.
In the exchange visits of I and transnational corporation and communication, know a lot of live thing base and but the circumstance of degradation material: When I take a team to visit company of 3 water chestnut, the live thing that saw they develop a success base polycarbonate project is plastic, the Shan Lichun that use surprise replaces double phenolic A, its transparency, optical function, tall wearability and anti-impact properties A of excel double phenol PC, already window of complete red-spotted stonecrop of make it car, future is used at car, the sources of energy not only, still will use instrument of Yu Guangxue, electron, adornment to decorate etc. Of chemistry of 3 water chestnut but degradation food packs film, empty vapour lock separates function good, last time is long, the exterior can be used at milk products to pack like high-grade paper already, also can use at bishop like vitreous bottle full-dress. When visitting center of LG chemistry innovation, also understand them to laying content radical chemical and new material in research and development. With Di Siman, Akema, win start the live thing that their research and development also knows in waiting for company communication base Ding Er acid and biology base nylon of long carbon catenary.
Everybody's familiar fuel alcohol, and dehydrate of raw material alcohol makes ethylene, obtain organic chemistry to taste then wait for polymer with polyethylene. The biology technology company that there is reportorial United States recently and chemical manufacturer and Lumusi cooperate, making propylene and whole live thing in development alcohol dehydrate base polypropylene technology, the construction dimensions in draw up 1.5 million tons / year. Korea LG company and Brazilian cloth the company also is in Lasike the technology that biology of research and development pledges alcohol dehydrate makes propylene and polypropylene, see a technology mature basically at present, it is cost issue remains only test and verify.
Ban to answer (be restricted) model makes, the biology that heats up greatly in last few years but degradation material gets together lactic acid, get together alkyl acerbity ester, still have acid of biology law Ding Er, third 2 alcohol, Ding Erchun, the fifth of the ten Heavenly Stem 2 amine and biology base polyester of nylon, biology radical, biology radical gets together carbon. Ba Sifu announces to acquire technology of Ding Erchun of biology radical 1.4- , will enlarge biology radical BDO and its ramification next (4 hydrogen furan, get together 4 hydrogen furan) supply; Biology of golden hair of Liaoning of 3 water chestnut chemistry of Nonamont of American Genomatica, Italy, Japan, Dong Li, China already built biology radical device of 1.4- Ding Erchun.
The most typical, provide most representative, also be technical craft the biology law third of the Du Bang wanting number with best competition ability of the most mature, market 2 alcohol. The third of biology law 1.3- of Du Bang company 2 alcohol, produce quality quantity, specific power consumption not only excel chemistry synthesizes craft, the market competition ability of its function and cost is stronger also, use at producing PTT polyester fiber not only, and already waited for respect application in things of floor of dress, residence, exercise, apply to cosmetic to wait to having distinct competitive advantage with high-end domain subtly especially.
Biology law polypropylene acyl amine also is excel of rare biology law craft a of chemical synthesis law representative product. Current organisms law obtains medicine and pesticide product more a few.
I also saw in domestic survey process a lot of companies of domestic are in biology radical chemical and but the innovation positive result that degradation data side obtains and industrialization device. I ever survey crosses what Hai Zhengsheng changes to get together lactic acid produces device, survey Guo Kai surpasses science and technology in aid 56 industrialization install the nylon of garden of Ningxin data industry buy, in the job as former as abundant also group has made communication with respect to innovation and industrialization. The biology of traditional petrifaction domain changes transition, will be future an important way.
6 ask: Biology radical and biology but home of degradation material international is increasing innovation, accelerate industrialization, a lot of people also are in prate biology base with biology but degradation has a lot of advantages, do all petrochemical and chemistry synthesize material after will by biology base replace?
Impossible. Biology radical chemical and biology but degradation material has a lot of advantages really, be in especially carry out “ strategy of double carbon ” , decrease carbon low carbon and can circulate respect, than having its distinct advantage with fossil resource. But, we must see biology radical chemical and biology radical data also exist restrict bottleneck.
The first bottleneck is biology radical is mixed but the industrialization of degradation material suffers technology and innovation restrict. Biology but the treatment function of degradation material, performance characteristics remain to promote and be improved, it is crucial core technology suffers again be restricted, the company that if plan to get together with the plan and construction,lactic acid produces device is not little, but the unit that masters crucial monomer third to make ester industrialization technology is very few however.
The 2nd bottleneck is biology radical chemical is mixed but degradation material, the product that has competition ability economically at present is not much. If do not have the allowance of policy sex and support, it is very difficult to be afraid can develop smoothly in market competition continuously.
The 3rd bottleneck more highlight, it is biology radical chemical and but of degradation material raw material restrict. Biology radical chemical and but degradation material is mixed with commissariat, sugar cane mostly at present starch is raw material, if came true to discard with the plant straw but renewable resources is raw material, will be foreground is infinite. But wait with straw at present deserted but renewable resources is raw material, its technology and economy pass nevertheless. If be raw material with commissariat and starch entirely, mass-produced chemical and but the word of degradation material, we and United States are cultivated in great quantities turn gene corn and Brazil teem with sugar cane to differ, in farmland China of little, populous, after all crop of our country grain 650 million tons, protect food safety to do not have big question, if be raw material to produce with commissariat,30 million tons of chemical are mixed but the word of degradation material, want to use up the 1/6 of grain total output, certainly will existence and person contend for grain and the real problem that contend for the ground with grain, the state cans be imagined!
The 4th bottleneck is but the synthetic data that degradation material can replace fossil raw material partly only. Because but the treatment of degradation material and performance characteristics replace existing synthesis data impossibly entirely; Also make the synthetic material that waits for field place to use and its modified and composite material because of car, electric equipment and high end, not was necessary all by but degradation material is replaced. But degradation material is in one-time pack, ground film enclothes the applied prospect with wait for a domain to having better, but not be the territory that suits all application to synthesize material and setting.
7 ask: Eliminate plastic pollution and deserted and plastic resource to change is using attention of international home height and the serious content that carrying out the action?
The 20 thumb of the party go out, chinese type modernization is person and the modernization with natural accrete harmony. Emphasize driving economic society to develop green to change particularly, the crucial link that low carbonization is development of implementation high quality. Implement comprehensive and managing strategy, advance meet by appointment of division of of all kinds resources to be used about, accelerate compose to build litter to use a system circularly.
Eliminate plastic pollution to get really the widespread attention of international society. Actual this also is the grim challenge that plastic trade urgent matter and development of plastic industry innovation face. Plastic be born oneself hundred years will produce about 9 billion tons in all, because use undeserved mix a large number of deserted and plastic addition after using, opposite state environment causes serious pollution, the pollution that causes to marine zoology especially is increasingly austere, already caused the widespread attention of international society.
Released 2022 according to organizing via closing " the whole world is plastic look into: Influence of economic drive, environment and policy choose " report, 2000~2019 20 years year, the whole world is plastic from 234 million tons / year increase 460 million tons / year, amplitude 96.6% ; Plastic rubbish criterion from 156 million tons / year increase 353 million tons / year, amplitude is as high as 126.3% ; The whole world was abandoned about 350 million tons 2019 plastic in only 9% is use again, 19% be burned, about 50% be filled to bury, 22% be discarded. The cry that eliminates plastic pollution so and action are taken seriously more and more.
In January 2022, the European Union was updated " pack and pack litter to dictate " , the requirement arrives 2030 on European Union market all and plastic in packing, should contain not under of 30% reclaim plastic, rise to 2040 65% . In November 2021, bureau of American environmental protection is released useless 2030 plastic reclaim utilization rate is achieved 50% . Australia " the country is plastic plan 2021 " in clear, plastic 2025 the reworked plastics content that pack should be achieved 20% . Canadian plan arrives certain 2030 plastic the scale of the reworked plastics in packing should be achieved 50% . Our country at the beginning of 2020, national hair changes appoint release with zoology environment ministry " the opinion that administers about strengthening plastic pollution further " , plastic to the standard litter reclaims grading target mixes benefit in order to and “ during 945 ” concrete step put forward to make clear a requirement.
On the plenary meeting of environment of the 5th U.N. that held last year, country attending the meeting agrees consistently to protect environment and human health not to get plastic pollution with “ , eliminate plastic pollution ” finally to be a target, from the angle of complete lifecycle, promote plastic can last design and harmless change processing. U.N. will come on stage on September 4 this year " plastic treaty 0 draft " , this " draft " covered plastic production, products plan, litter to manage complete lifecycle, the specific detail that decides plastic pollution convention directly and trend, provided guidance and support to will negotiate between the 3rd round of government that Luo Biju runs inside November this year. Include Chinese government inside the world is main country and each organism, large the enterprise studying seriously, chinese petrifaction federation also travels together with the world together active with science, the answers with the research of be practical and realistic plan of objective justice. Of course, give priority to with many transnational corporation in last few years initiate the “ that hold water AEPW” of alliance of terminative and deserted plastic pollution, also had offerred a lot of train of thought, plan and measure to eliminate deserted and plastic pollution, did a large number of fruitful works.
8 ask: Is plastic loop used what important way is there? Change to deserted and plastic resource use policy asks?
Deserted and plastic resource changes a loop to use minute of physics loop and chemical circulation. Physics is used circularly is the realistic way that discards plastic resource changes stair recycle, a lot of units, scientist and personnel of innovation of science and technology are increasing innovation strength, exploration and innovation discard plastic physics circulates the method of recycle and plan. Qu Jinping academician uses the special device of innovation and processing technique, came true deserted and plastic need not machine directly after sorting, processing is clean, implementation resource changes recycle. Ba Sifu research and development is successful a kind of plastic additive, of recycle of the physics after can be being used at reclaiming plastic in, its machinery function promotes apparently, service life is lengthened, use at reclaiming polyethylene, polypropylene plastic in, also use at the car circularly, pack, the domain such as farming film, already applied at the area such as Europe, America, middle east, Asia at present.
Deserted and plastic chemical loop resource changes recycle, it is the innovation content that takes seriously domestic and internationally highly currently. Because chemical loop can realize deserted and plastic high price value to change recycle, a lot of transnational corporation and domestic company also fetched significant level sex gain. Have a plenty of will deserted plastic the method that use depolymerization or decomposes, reductive for monomer, again aggregate implementation chemistry circulates. Understand according to me, the earliest Du Bang, in recent years henry Si Mai, medium petrifaction already mastered “ methanol Shi Ke courtyard to decompose technical ” to will abandon polyester (PET) carefe, decompose didymous benzene ester of armour of 2 formic acid and glycol monomer, synthesize new PET colophony afresh next, realized closed circuit chemistry to circulate. Also have a plenty of will deserted plastic aerification to enrage or heat up solution to be tasted for oil for synthesis, synthesize chemical and its polymer again. The craft of thermochemistry splitting decomposition that if Basifu is grinding,delivers, taste useless plastic hot splitting decomposition for oil or synthesize gas, the oil that hot splitting decomposition obtains is tasted in Ludeweixi harbor unifinication base replaces fossil raw material, the olefin that obtains via splitting decomposition produces all sorts of chemical or polymer further. Its character reachs provision level, use at cheese to pack, heat-insulating material of transparent freezer component, heat preservation, and the door handle of Benz.
In addition, yi Shiman realizes a series of polyester through technology of polyester second birth the chemistry of plastic litter reclaims, with conventional technology photograph the greenhouse gas than can reducing 20%-30% is discharged. Environment of Japanese god steel uses fluid-bed aerification heat, the useless old plastic aerification that uses low purity, not easily circularly, acquisition synthetic air is made take methyl alcohol, this project plans to began operation in September 2023, every processing abandons this kind of method 60 thousand tons plastic, can reduce 100 thousand tons of carbon dioxide integratedly to discharge. In the level sex positive result that also obtained plastic loop work of family of courtyard of petrifaction stone division, spaceflight to use.
The policy that uses to plastic loop asks. Developed country and the area such as European Union, United States, Canada spoke of in front plastic to reclaiming loop is used put forward to add proportional target to ask. Our country " the opinion that administers about strengthening plastic pollution further " plastic to the standard also litter reclaims use raised a requirement. Especially of print and distribute of the State Council " the carbon before 2030 amounts to peak action program " in “ circular economy aids force to fall part of carbolic action ” , emphasize “ arriving 2025, 9 kinds of main renewable resources such as scrap iron and steel, waste paper, useless plastic, useless balata use a quantity to achieve 450 million tons circularly, achieve 510 million tons to 2030. ”“ strengthens plastic pollution entire chain to administer the specific target such as ” and requirement. Increase deserted and plastic circular benefit dosage, reduced the wastage of fossil resource, reduce what the mankind waits for fossil resource to coal of oil natural gas to depend on not only, and also reduced greenhouse gas carbon dioxide discharge.
Actually, we are certain and ambitious change pair of deserted and plastic resource to change the knowledge that use, this is to settle plastic pollution is actual and important way! It is current that plastic physical stair is used circularly relatively applicable method. Chemical loop is to realize useless plastic high price to be worth resource to change the important method that use, this also is current chemist and chemical engineers the main task that focusing tackles key problem. Deserted and plastic chemical loop resource changes recycle to look from technical angle is not difficult problem, because chemical reaction is reversible mostly: Can add up to achievement to be able to be decomposed, can aggregate can depolymerization! The high polymer polymer that aggregate reaction gets him chemist, it is certain can pass depolymerization (or splitting decomposition) reaction makes decompose, this is the fundamental of chemical reaction, also be chemist people special skill, on the technology nonexistent obstacle. At present the biggest obstacle is economically, it is cost and price issue, the plastic price prep above after the operation cost that is an enterprise and second birth or under give birth to plastic price formerly? Namely problem of economic competition ability.
I think the problem of deserted and plastic pollution that looks increasingly austere today can be solved eventually, can having technical plan merely is insufficient, return those who need policy to urge the action of the consensus with competition ability of support, economy and people and whole world.
9 ask: What does synthetic material amount to peak carbon to counteract ” to have to contribute to “ carbon?
Synthesize material to expect to carbon of human society “ Da Feng carbon counteracts ” to having important contribution. From plastic be born 100 come for years, in numerous application the domain came true to take the place of with model steel, wait with model Dai Mu, made important contribution to managing specific power consumption and environment of protective organisms' habits. Synthetic fibre is improved not only and abounded the daily life of people greatly for example, and made important contribution to protect farmland; Be like modified again a large number of application of plastic, high-powered composite material in industry of world auto industry, aviation, urge car and plane implementation light quantify, energy-saving to whole society fall bad news has important contribution. The application that expects through synthesizing material with energy-saving fall bad news and decrease carbon to fall case too numerous to mention one by one of carbon.
Synthesize the innovation of high polymer material for raw material with carbon dioxide, it is global height takes seriously, a heat that ongoing hair and technology tackle key problem, many scientist of domestic and orgnaization of not little research and development accumulated achievement of sex of a lot of phase and valuable experience. Is a course C of carbon dioxide and hydrogenous synthesis methanol, classics? Chemical course, methanol makes alkene expect to synthetic material; Another course is for raw material with carbon dioxide straight joint becomes high polymer material.
Twelve company of the United States had realized carbon dioxide and water to be made polypropylene, the effect of its polypropylene and function and naphtha polypropylene are same, already with run quickly the car part that cooperative production gives the first to be raw material with carbon dioxide, and already waited for many products with car, household, dress, and Bao Jie and American aerospace bureau reach collaboration. Ba Sifu synthesized acrylic acid for raw material and ethylene with carbon dioxide, produce a colophony of tall water imbibition to be used at baby and senile things then. The carbon dioxide that Japan makes iron use puddling blast furnace or electric stove to discharge and binary mellow reaction synthesized polycarbonate 2 alcohol, as the raw material of downstream polyurethane, this one innovation reduced carbon dioxide to discharge not only, and replaced make first for raw material with carbon monoxide and phosgene carbonic acid 2 armour ester, make with binary mellow reaction again take polycarbonate the conventional technology of 2 alcohol, eliminated the phosgene law tradition with dangerous extremely high sex craft, predict practical 2030 change. Make for catalysis of biology of raw material classics with carbon dioxide take Ding Er sick at heart, achieved live thing but the raw material of degradation material PBS, already obtained a lab to study positive result.
Above innovation is synthesize new material for raw material with carbon dioxide, synthesize the innovation that organic chemistry tastes for raw material with carbon dioxide, also get coequal take seriously, also accelerate in synchronism. These innovation achievement will reduce carbon dioxide to discharge directly after large-scale industrialized promotion. Carbon dioxide resource changes the innovation that uses green chemistry to obtaining progress and breakthrough steadily, be sure 15 or so years to be counteracted for carbon too again make important contribution.
Innovation is everlasting, the development of material science is everlasting. High polymer material was human civilization and social progress to make important contribution since be born, future will continue make new contribution to drive technical revolution and industry to change! Use the problem that creates in the process because of high polymer material it seems that today, regular meeting gets as the progress of innovation and technology appropriate is solved, human future is met certainly more good!
