Xinhua Xu vulcanization process of rubber gasket

 
Xinhua Xu vulcanized rubber gasket is through chemical cross-linking between rubber molecules will be substantially converted to plastic raw rubber elastic and dimensionally stable product, the physical properties of vulcanized rubber stable, extended temperature range. "Vulcanization (Curing)" the term commonly used throughout the rubber industry, plays an important role in rubber chemistry. Vulcanized rubber molecular chains (crosslinking) reaction capacity depends on its structure. Unsaturated diene rubber (e.g. natural rubber, styrene-butadiene rubber and nitrile rubber and the like) a molecular chain containing an unsaturated double bond, with sulfur, a phenol resin, an organic peroxide or the like is formed by an addition reaction or substitution molecules between crosslinking. Usually unsaturated rubber crosslinked with a radical having a certain energy (such as organic peroxides) and high-energy radiation. Special rubber containing functional groups (such as chlorosulfonated polyethylene, etc.), the crosslinking, such as rubber sulfonamido by metal oxides, amines by reaction with a specific cross-reactive substances with established various functional groups formed Union.
 
 Vulcanization process is one of the main rubber products processing, under heating or irradiation conditions, raw rubber and rubber compounds react chemically curing machine, rubber by the linear structure of macromolecular crosslinked to become three-dimensional network structure macromolecules, resulting in physical and mechanical properties of rubber and other properties have been significantly improved, this process becomes vulcanization, along with the development of technology and production, Xinhua Xu and high-temperature vulcanizing machine is no longer a necessary condition for curing some rubber material can be at lower temperatures, even at room temperature and can be cured drinks, some compounds of available physical methods, such as y-rays so that the crosslinked rubber without the need for a vulcanizing agent, vulcanization broader definition so that, under certain conditions, , linear rubber molecules into a network structure of the process. After the vulcanization of rubber, while the performance will change. Xinhua Xu natural rubber, for example, with a higher level of cure, mechanical properties will change. Elasticity, tensile strength, elongation strength, tear strength, hardness will increase, but elongation, compression set, heat fatigue will be reduced; changes in physical properties, air permeability, water permeability reduce insoluble, only swellable improved heat resistance; chemical stability will change remarkably improved. In fact, he said the reason is nothing more than a chemical crosslinking reaction so highly active group or atom exist, making the aging reaction difficult. Network structure hinders the diffusion of low molecular weight, resulting in free radicals cause aging of rubber is difficult to spread.
Xu Xinhua elasticity rubber gasket can compensate for the displacement error, so as not to let him work a lot of wasted effort situation, while some of the ways it corresponds to the connection can reach its surface without any corrosion the condition, which itself has a compression performance is very obvious, and they are in contact with the area. He can reach a state of the fastening bolt, it is able to fit well, so as to ensure its sealing work, the performance of its resistance to temperatures and some materials are selected to ensure that the system in its lowest temperature and the maximum temperature can be normal use.
 
For some losses Xinhua Xu rubber gasket produced are very obvious, it's a condition for stable systems is possible without any influence, but also for some of his elastic features are also very powerful of.
