One, the function characteristic of chloridize pvc

Chloridize pvc (CPVC) it is by polyvinyl chloride farther chloridize is gotten, it is a kind of interpose at balata and plastic the material of elastomer of new-style high polymer between. to PCV, the hear resistance of CPVC, corrosion resistance, flame retardant waited to have very big promotion from extinguish sex, mechanical function, there is wide application in the domain such as building materials, electric, chemical industry, metallurgy, medicine, coating.

2, CPVC industry is relevant policy

Since 2010, ministry of letter of the State Council, industry, hair changes appoint wait to publish a project in succession plastic industry is relevant policy, main policy content includes a project around positive development plastic inside advanced construction material, development includes special type project plastic preparation technology inside the preparation technology of material of construction of high-powered high polymer, strengthen application the research, intelligence that advances material to produce a course energetically is changed and green is changed transform, .

3, catenary of CPVC industry industry

Chloridize pvc (CPVC) is polyvinyl chloride (the product of modified of PVC) farther chloridize, its are chloric content is) of 65%~72%(bulk mark commonly. CPVC besides a lot of good performance that hold PVC concurrently, the corrosion resistance that its have, hear resistance, dissolubility, anti-flammability, mechanical intensity all have than PVC bigger rise, consequently CPVC is the new-style stuff with good performance, be used extensively at the domain such as building, chemical industry, metallurgy, shipbuilding, electric equipment, spin, applied perspective is very wide.

At present our country is big country of global pvc production, always produce can occupy the whole world to always be produced about can 45% above. According to statistic, 2021, our country pvc is produced can be 27.13 million tons, grow 1.8% compared to the same period, produce can net growth 490 thousand tons, crop is 21.3 million tons, drop compared to the same period 6.6% .

4, Chinese CPVC industry grows the current situation to analyse

1, market dimensions

As the ceaseless development of society of our country economy, CPVC goods gains the favour of people because of its superior performance. According to statistic, dimensions of market of pvc of our country chloridize grew 1.715 billion yuan 542 million yuan from the forehead 2014 2021, CAGR is 21.17% .

2015-2021 year dimensions of market of our country CPVC and add fast

2, crop

Domestic CPVC technology and foreign photograph are compared still apparent lag, colophony quality and treatment function and entrance product photograph are very older than existing difference, applied domain is restricted. The foreign manufacturer such as beautiful, Europe, day is forestall China market, sell CPVC special material only, a few high quality are in charge of the special CPVC raw material such as material, pipe fitting, profile to still need to count an import. According to statistic, crop of pvc of our country chloridize went to one hundred and ten thousand eight hundred tons from forty thousand four hundred tons of growth 2015 2021, CAGR is 18.31% .

3, demand

2015-2021 year yield of pvc of our country chloridize presents constant growth state. According to statistic, demand of pvc of our country chloridize came one hundred and eighteen thousand two hundred tons from fifty-one thousand one hundred tons of growth 2015 2021, CAGR is 15.0% .

2015-2021 year demand of our country CPVC and add fast

4, the price goes situation

Sufferred the effect of the element such as epidemic situation 2021, value of global heavy goods is total go up bigger, chloridize pvc all price rises considerably, chloridize pvc market all valence 14509 yuan / ton.

5, analysis of pattern of competition of Chinese CPVC industry

The whole world produces CPVC resinous enterprise to already had more than 20, produce can make an appointment with 450 thousand T/a, basically wait in the United States, France centrally, among them doctrine of look of firm of use gas of Ma of French A division, the others country produces craft to all use method of water photograph in suspension. Firm of profit of American road gain produces device now already can achieve 100 thousand T/a, produce a business for the biggest CPVC on the world, company of industry of chemistry of seeper of Japanese heart hill produces a business for the 2nd big CPVC, company of company of industry of chemistry of Japanese bell deep, calcium carbide industry and company of German Ba Sifu is the main CPVC on the world produces a business. In recent years, as the progress of domestic PVC aggregate technology, a lot of companies of our country begin to consider and produce CPVC, our country CPVC basically produces manufacturer to be as follows:

6, the development trend of CPVC industry

From the point of existing research progress and development general situation, although the production of CPVC still faces a few problems, but of the research of CPVC modified strategy and practice method discuss, also develop the reference with was offerred important further to its. And CPVC itself has the character such as stronger corrosion resistance, hear resistance and anti-flammability, the treatment difficulty that once solved whole production effectively,link exists problem, its apply limits to will get farther promotion.

From the point of development trend of future, the research of CPVC relevant domain, will around how to solve its to decompose temperature and treatment temperature to be close to too, treatment difficulty is put the problem such as blemish spreads out. In addition, the efficient and compound heat that excogitates a kind to heat up oxygen to decompose mechanism in the light of CPVC stabilizes a system, maintain the sense that having outbalance to the thermal stability of link of CPVC data processing; Excogitate in the light of the CPVC, carrier colophony that has good consistence, having positive effect to the CPVC viscosity, settlement that sorts metamorphic problem; Produce what exist in the process to fight concussion blemish in the light of CPVC, research and development goes out effective, in the light of the modifier that mixes a system in all, will CPVC and have the high polymer that combats impact strength certainly to undertake be mixinged in all, can alloy of CPVC of better land promotion uses value integratedly, of CPVC of give attention to two or morethings fight concussion character. With respect to afore-mentioned CPVC further progress puts some problems to look, want to realize the farther promotion of CPVC application level, relevant researcher needs to undertake examining reflection to the solution of this kind of problem, carry the kind of experiment test and verify, discuss its feasibility and practical effect.

In addition, profit from CPVC is in the inherent advantage of a lot of respect, CPVC can be used at chemical industry not only material of anticorrosive equipment, canal, electron yuan parts of an apparatus, still will be in the domain such as modified of fibrous of the production of composite material, coating and adhesive, chloridize obtains larger development space, especially of alloy mix make, CPVC and a variety of plastic sophisticate, can better improvement its material function, then development gives performance more advantageous project is plastic. Even the viewpoint puts forward, CPVC still can be made with what make transparent material.
