Recently, the “ that academy of oily chemical industry of Chinese stone oilstone and Lanzhou petrifaction company rely on own development exceeds pure ” medicine to wrap material to use technology of platform of polyethylene colophony research and development, produce and sale of implementation of accumulative total of special feed LD26D measures the polyethylene ampoule of development many tons 20 thousand, more general makings raises product price 1/3. This is indicating implementation of development of high quality of industry of Chinese oil polyethylene is new breakthrough, promoted our country considerably medical the technology of polyethylene develops a standard.
Current, capable person of bag of our country medicine exceeds 200 thousand tons with polyethylene market demand / year, basically use at medical medicines and chemical reagents of bag of the ampoule, compound infusion, profess to convinced is packed wait for a domain. Among them, medical the polyethylene dosage of the ampoule makes an appointment with 20 thousand tons / year, the market is forestall of foreign company place.
To solve high end of our country polyethylene medical makings be enslaved to be enslaved to the person's predicament, march 2011, in December 2013, the Chinese oil oil refining that sells the unit such as the company to assume by company of petro-chemical academy, Lanzhou petrifaction, southwest chemical industry and “ of chemical branch task are medical polyethylene of class low density is ” of the development of special feed and application, great science and technology is special “ is medical and special makings development and standard research ” early or late.
The abidance that passes 10 one's remaining years tackles key problem, scientific research group obtains major breakthrough in crucial core domain eventually. We built “ medical bag capable person uses assessment of token of polyethylene colophony structure, performance, precipitate to analyse a method, formed medical polyethylene precipitate detects analytic technology, use lab technology, announced medicine hires capable person with polyethylene the form etiquette law of migratory content, wrap what material uses index of technology of polyethylene colophony core to put forward to provide theory and data base for medicine, grind give out precipitate technology of low migratory control. Wang Zhuoni of controller of group of ” this project says.
Project group development studies extrahigh voltage issues catenary of freedom radical polymerization to grow mechanism, formed the influencing factor new knowledge that catenary of young member of the oligomer in polymer forms, built the young member oligomer below condition of extrahigh voltage polymerization to control a technology, from colophony manufacturing fountainhead controls the generation of precipitate.
In the meantime, project group established the test method of fine pink content and matter content, can detect effectively quickly medical bag capable person uses the matter content in polyethylene colophony; Through mastering polymerization of ethylene superhigh pressure parameter of the craft in the process increases the influence rule that changes with catenary to polymer catenary, the design developed microtherm answer to deserve to cause a system, formed new-style low temperature to cause engineering technology of polyethylene of synthetic superhigh pressure, built extrahigh voltage to react low frit shows the product defends sticky wall technology below the condition, super- pure change polyethylene to manufacture a technology.
Afore-mentioned “ ‘ exceed pure ’ medicine to wrap material to use polyethylene colophony technology, captured medicine wraps material to use polyethylene colophony oligomer, small foreign matter migratory control difficult problem with separate out, solved polyethylene colophony to be used at high risk medicine to include the technical difficult problem of material, realized polyethylene ampoule of special feed LD26D homebred change. ” Wang Zhuoni says, they still built medicine to wrap material to be produced with polyethylene colophony, pack, quality of Chu Yunhe product runs a system, solved medicine to turn manufacturing difficult problem with polyolefin dimensions.
In the meantime, petro-chemical academy still combines academy of calibrating of Chinese food medicines and chemical reagents to wait, built the Chinese medicine that includes the test such as 21 biology, poisonous a Confucian school of idealist philosophy of the Song and Ming Dynasties to use system of standard of polyolefin security assessment technique, solved medicine to apply evaluation standard to be short of the difficult problem of estrangement market admittance with polyolefin colophony.
Current, chinese oil is become home can be developed exclusively and produce new-style polyethylene ampoule the enterprise of special feed, still make LD26D price relatively entrance product was reduced nearly 15% , reduced the burden using drug of common people, initiated injection to use polyethylene ampoule raw material is homebred change epochal.
Li Anquan of vice director of research center of Lanzhou chemical industry expresses: “‘ exceeds pure ’ medicine to wrap material to use technology of polyethylene colophony platform, the clean that includes level of colophony of talent level polyethylene to medicine purifies production base construction, country is medical system of polyolefin security evaluation is built, eliminate the bottleneck that restricts medicine to use catenary of polyethylene colophony industry to develop, get through and liquid medicines and chemical reagents contact polyethylene medicine for a long time to include the application of whole technological process of material, aggrandizement is homebred and medical the respect such as the applied promotion of polyethylene made positive contribution, to ensure people healthy contributed ’ of ‘ oil wisdom with national security. ”
