PVC, the abbreviation PVC (Polyvinyl chloride), Dalian pvc sheet, vinyl chloride monomer (vinyl chloride monomer, referred to as the VCM) peroxide, azo compound initiator; or in the optical, thermal effect by free radical polymerization reaction mechanism of polymerization of the polymer. Vinyl chloride homopolymers and copolymers of vinyl chloride resin system call. PVC is amorphous white powder, the degree of branching is small, the relative density of about 1.4, a glass transition temperature of 77 ~ 90 ℃, Zhengzhou pvc sheet, about 170 ℃ begins to decompose [1], the difference between light and heat stability, in above 100 ℃ or after prolonged exposure to sunlight, it will break down and produce hydrogen chloride, Hefei pvc sheet, and further autocatalytic decomposition, causing discoloration, physical and mechanical properties also decreased rapidly, pvc sheet, in the practical application of the stabilizer must be added in order to improve heat and light stability. Crosslinking into radiation crosslinking and chemical crosslinking. 1. The radiation crosslinking. The use of high-energy rays, electron beams generally cobalt 60 radiation source generates radiation or electron acceleration occurred mainly the latter. Coupled to help crosslinking auxiliary (two or more carbon-carbon double bond monocoque) crosslinking. But the operation is difficult, for equipment requirements. 2. Chemical cross-linking. Use triazol-dimercapto-amine salt (FSH) crosslinking, amine crosslinking mechanism in conjunction with sulfhydryl attack carbon-chloro-polar bond implement substitution reaction. UV resistant products after crosslinking, solvent, temperature, impact toughening performance overall. Sichuan pvc sheet, plate Conte (online consultation), pvc sheet provided by the Shandong Petroleum Equipment Co. Conte. Conte Shandong Petroleum Equipment Co. (www.njtlgcbc.com) Shandong Texas, a plastic plate (sheet, section), rods leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs.
