Q:What advantage does ethylene propylene rubber with three yuan compare to two yuan ethylene propylene rubber?
In recent years, the third monomer and new technology development, foreign developed 1 7- octadienoic, 6, 5, two 10- methyl -1, 9- eleven, 7- two three ene 3, methyl -1, 6- octadienoic, 5 7-, two methyl -1, 6- octadienoic, 7- methyl -1, 6- octadiene as the three EPDM third monomer, the performance of three Yuan rubber has been enhanced. The monomer and content of third monomer in three yuan ethylene propylene rubber have direct influence on vulcanization rate and vulcanizate property. Among them, dicyclopentadiene (DCPD) as the third monomer, although the price is low, but the three Yuan rubber vulcanization speed is slow, difficult and high degree of unsaturation diene rubber and use; to ethyiidenenorbomene (ENB), 6 10-, two methyl -1, 5, third monomer three Yuan rubber vulcanization speed 9- eleven three ene as fast, the former has become the main varieties of three yuan of ethylene propylene rubber. The third monomer content in iodine said three EPDM iodine value is generally 6-30, mostly around 15. The iodine value is 6-10, curing speed is slow, difficult and high unsaturated rubber; iodine value is 25-30, for ultra high speed curing type, available in any proportion and high unsaturated diene rubber and use. Therefore, three yuan ethylene propylene rubber and other rubber in use, should pay attention to choose the appropriate three yuan ethylene propylene rubber varieties.
Q:What are the bridge rubber air bags used for?
Note: when the inner mold of the airbag is used, it is necessary to brush the isolating agent to reduce the pumping resistance. The airbag does not allow the oil to replace the isolating agent. On the one hand, the oil will erode the rubber, and the other oil will contaminate the reinforcement. It is ideal to dilute with soap water as a release agent. Soap and water ratio is about 1:20.
Q:What are the forming methods of rubber products?
In these methods, injection molding has the significant advantages of simplifying process, reducing the number of operators; second, reduce the energy consumption of about 10%; the production efficiency is improved by 4 ~ 7 times; improve product uniformity, stability, size precision and the qualification rate; reduce the flash, saving material and convenient operation;, low labor intensity, high degree of mechanization and automation. Therefore, in recent years, more and more attention has been paid to injection molding technology, and it has been developed rapidly in rubber products production
Q:What's the difference between natural rubber and three yuan ethylene propylene rubber?
The dielectric properties of natural rubber are a nonpolar substance that is soluble in non-polar solvents and non-polar oils. Natural rubber is not resistant to cyclohexane, gasoline, benzene and other media, non vulcanized rubber can be dissolved in the above medium, vulcanized rubber swelling. Natural rubber insoluble in polar acetone, ethanol, more insoluble in water, resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide and so on.
Q:How to distinguish between rubber and polyvinyl chloride?
1) preparation: vinyl chloride monomer (vinyl, chloride, monomer, referred to as VCM) in peroxide, azo compounds and other initiators; or under the action of light and heat, polymerization by the principle of free radical polymerization of polymers. The vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resins.2) properties: white powder, amorphous structure, degree of branching is small, the relative density of about 1.4, the glass transition temperature of 77~90 DEG, 170 DEG C to decompose, the stability of heat and light, at 100 DEG C or after long time exposure to sunlight, will decompose and produce hydrogen chloride, and further automatic catalytic decomposition that change, the physical and mechanical properties also decreased rapidly, in the practical application must be added in order to improve the stability of heat and light stabilizer of the.
Q:Why does rubber burn black smoke?
So, when rubber burns, it does not burn completely. There are many black carbon, which form black smoke
Q:High strength rubber repairing agent?
At present, more commonly used high strength rubber repair agent, mostly imported. Like some industrial and mining belts in the repair of broken belts, the choice of sk358 such a two-component rubber repair agent used, the effect is really better.
Q:What problems need to pay attention to when inflating the pipe?
Rubber pipeline plugging bag should keep the inner pressure of the gasbag is uniform when inflated, inflated slowly rising inflation, observe the pressure gauge without change, such as pressure gauge shows rapid rise in inflation is too fast, the inflation rate should slow down, stop valve will tighten slightly, reduce the inlet velocity, or the speed is too fast, faster than pressure is likely to break into the rubber balloon. - Zhang
Q:What is rubber material?
Rubber (Rubber): highly elastic polymeric material with reversible deformation. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. Rubber is completely amorphous polymer, its glass transition temperature (T, g) is low, the molecular weight is often large, more than hundreds of thousands.
Q:Is the odour emitted by industrial rubber poisonous?
In order to make all the necessary coordination agent in rubber, rubber Plasticating must first go through improving the plastic; then by mixing carbon black and all kinds of rubber and rubber additives are evenly mixed into rubber;
