1、国内硅胶行业的三大发展优势（Three development advantages of domestic silica gel industry）The domestic silicone industry three development advantages of.Txt I this person never, generally have revenge on the spot I quote. Theres nothing to do. Dont look for me! Even believe has a lie in the middle! I like you so m
2、uch, you like me will die ah? Im not RMB, how can everyone like me? Three development advantages of domestic silica gel industryDomestic silica gel industry has three advantages. The healthy development of the silicone rubber industry depends on continuously accelerating its technological progress a
3、nd strengthening the development of high-performance products. At present, the competitive advantage of Chinas synthetic rubber industry lies in:1., there are certain core technical support. Our country has established including the 7 basic types of plastic is a complete product system, which has th
4、e strong support of SSBR core technology (SSBR), thermoplastic styrene butadiene rubber (SBS) and butadiene rubber (BR) and other products in the domestic market share is high, and can be extended in time according to the market development ability the capacity, is conducive to further expand market
5、 share. Ethylene propylene rubber (EPR), nitrile rubber (NBR) and butyl rubber (IIR) products such as the introduction of technology and construction equipment, the products have successfully entered the market, and there is a certain development in the device capabilities and product brands, laid t
6、he foundation for the future market and technology to further expand capacity.2., China has huge market demand. The investment focus of the world rubber industry has shifted to developing countries, especially in China. China is becoming the worlds manufacturing base for tire and rubber products and
7、 the key areas of the worlds silicone rubber market competition.3. lack of natural rubber resources in china. Chinas natural rubber has long been in short supply, and its import volume has risen from 850 thousand tons in 2000 to more than 1 million 600 thousand tons in 2007, and its dependence on fo
8、reign countries has been increasing day by day. Increasing the proportion of silicone rubber has become an important way to solve the problem of insufficient supply of natural rubber. Some silicone rubber, which can substitute for some or all natural rubber, will have a larger market.Reinforcing sys
9、tem of rubber additivesAdditives in rubber processing, some requirements of high growth, high hard rubber reinforcement simply increase the amount of carbon black is of no avail, because this Mooney viscosity is too high, the heat is too large, difficult to mixing, extrusion, molding operations that
10、 give trouble. In these high hardening, high reinforcing rubber, if combined with phenolic resin for rubber parts instead of carbon black can not only make the process smooth, and can obtain the ideal hardening reinforcing effect. However, commercially available oil filled phenolic resins are not su
11、itable for use as rubber stiffening agents or reinforcing agents because they are not only safe to process but also reduce the fatigue and brittleness of vulcanizates.The international popular special rubber reinforcing resin must be added to the third monomer condensation, and through specific oil
12、or latex modification, the product must have high hardening, high reinforcement and heat resistance, processing safety, technical features of good compatibility with rubber. There are mainly 3 kinds of rubber reinforced phenolic resins reinforced by the world. They are two kinds of resins, namely, b
13、enzaldehyde, phenol, formaldehyde, two step resin, wood tree oil or tall oil, phenolic resin and latex, modified phenolic resin.In China, the rubber industry research and Design Institute has synthesized the technical characteristics of international rubber reinforced and reinforced resins, and succ
14、essfully developed PFM products, which are produced by Beijing Chemical Co., ltd. According to the needs of different rubber products, the following characteristics of PFM series products: PFM M: oil modified phenolic resin was two order of three yuan, with a high hardening, high reinforcement and h
15、eat resistance properties, adding 10 phr, NR/BR/ can make the carbon black (and with 70/30/60) vulcanizates shore A hardness reaches 95 degrees. PFM C: oil modified phenolic resin was two order of three yuan, with a high hardening, high reinforcement and heat resistance properties, adding 10 phr, NR
16、/BR/ can make the carbon black (and with 70/30/60) shore A hardness of vulcanizate reached 94 degrees. PFM P: oil modified phenolic resin with two order, hardening, high reinforcement and heat resistance properties, adding 10 phr, vulcanized rubber shore A hardness of up to 90 degrees. PFM R: light oil modified phenolic resin with two order, hardening, high heat resistance, wear resistance, reinforcement. Can be used in light colored reinforced products.
