PVC composition structure character as a slightly yellow translucent and shiny. Transparency better than polyethylene, polypropylene, polystyrene poor, with the additive, divided into soft and hard PVC, soft products soft and tough, feel sticky, hard ware harder than low-density polyethylene, but lower than polypropylene, will appear at the inflection bleaching. Common products: plates, pipes, shoe soles, toys, doors and windows, wire jacket, stationery, packaging boxes. pvc 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 and electron acceleration produced, but 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-crosslinked amine salts, amine salts triazol-dimercapto-FSH, amine crosslinking mechanism combined with the sulfhydryl attack carbon-chloro-polar bond implement substitution reaction product after crosslinking UV resistance, solvent resistance, heat resistance pvc pipe pressure, impact toughness, etc., have comprehensive manner. And that device 1. solve the difficult problem of radiation cross-linked. 2. toughened PVC pvc pipe manufacturers, weather, temperature pvc pipe, UV resistant and so performance has greatly improved. PVC 3. mitigation of radiation crosslinking or peroxide crosslinking degradation, discoloration overcome serious shortcomings. To give the appearance of products with better performance. The process is simple, suitable for molded pvc tubing agent, coating, rotational molding process and so on. PVC (full name Polyvinylchlorid), the main ingredients of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility and the like. This uppermost surface film is painted, the main component of the middle is PVC, the lower is the adhesive-backed. nature pvc pipe applications PVC pipe is a vacuum film for packaging various types of panel surface, it is also known as decorative films, with film, used in building materials, packaging, pharmaceutical and other industries. Building materials industry accounted for the largest proportion, 60 percent, followed by the industry, the packaging industry, there are a number of other small-scale applications. PVC pipe is divided into two kinds of PVC water supply and drainage, water supply and drainage for municipal and industrial water supply and drainage, civil drainage, irrigation, watering and other vegetation. Five pvc pipe, pvc pipe, sea Widex Widex provided by Qingdao Rubber Material Co., Ltd. Widex Qingdao Rubber Material Co., Ltd.
