chlorine 化PVC
chlorine polyvinyl chloride (PVC) is polyvinyl chloride (PVC) resin rear chlorine to types polymer.
chemical and property 质
PVC separation upper again increase chlorine rear, material CPVC resin 玻璃化 temperature degree （Tg） will improve/increase 至239至275°F temperature degree scope/range inner; lower heat deflection temperature (HDT), according to its formulation different, will from PVC material material 约158°F improve/increase to 180至219°F temperature degree scope/range inner. is 说, outer increase chlorine, improvement hard PVC flame retardant property, property, improve/increase resistant strong/high degree and modulus, 而保留 it has good property can: dimensional stability, excellent chemical resistant features and good electrical property can.
CPVC mixed material plastics still maintain relatively high chlorine content resin high hot temperature degree features, its material material mixed process and PVC mixed versus similar, more complex, more difficult.
mixed material can application 传统 挤塑, calendering, injection molding and other processing pipe/tube, type 材, sheet/slice and other thermoplastic property molding methods. processing use di screw machine processing powder material material and use mono screw machine processing material material.
use types combined solvent agent solvent understanding CPVC resin, can made types very has use bonding agent. processing also can use its solvent liquid formed made CPVC流延 film.
processing
although CPVC is 以PVC is made polymer, and PVC共 has certain property can, is, it is types has its features polymer, this for/regarding its processing especially important. 例如, CPVC polymer melt temperature degree scope/range from 400°F直至 most high to 450°F. processing need using/adopting or 不锈钢 模头. 挤塑模头必 must is good type, ensure can long time processing 运转. sheet/plate 模头不 can obtain 满意 挤塑运转 time. is very good control pipe/tube and type 材 挤塑 dimensions, most good using/adopting true type technology. equipment 需配备至 less 40马 force screw plant/unit. has types screw design can 适于挤塑 processing various formulation good mixed material.
injection molding processing need using/adopting has combined 适导出 long degree low pressure shrink screw. pipe fittings use material material need using/adopting 尖梢式塑化 screw. low viscosity, high material material need using/adopting sliding ring processing screw, can using/adopting 球形止逆 screw. injection molding mold using/adopting 不锈钢材 material, less using/adopting or 镀镍材 material.
application
due to solid has chemical resistant features, high degree rigid property, solid has resistant property, excellent resistant strong/high degree, resistant inner light, resistant gas features and combined density, make CPVC材 material tool has application market.
传统 upper, CPVC材 material used for manufacturing cold. hot water pipe/tube, pipe fittings and industrial chemical liquid 体 传送 pipeline, pipe fittings, and other. most new technology development make can molding 窗玻璃镶装 pressure strip/profile, cooling sheet/plate, automotive inner use products, waste material device tool and various outer deep color application material product. 一 定 made injection molding product grade can office machine outer housing/shell, long 途通讯 equipment use product and 一 仪 device parts. most new development is anti system pipe/tube, pipe fittings use CPVC material material.
CPVC most 早（ large 约1960 year ） used for manufacturing use cold, hot water tube/pipe and pipe fittings. its pipe/tube hot loss consumption low, water 滴, water poly 积, in 180°F temperature degree and 100磅／英寸2 pressure lower sustainable application, USA ring 境卫生基金会 can use water certification, 因而, make 数百万居住 small using/adopting CPVC pipe/tube. CPVC material material made formed water leading parts and used for use water system in, tool has advantages.
construction upper other application also 包括窗玻璃 deep color pressure strip/profile, frame 架, this is is CPVC has relatively high heat resistant property, can resistant deep color poly hot.
CPVC chemical resistant features make can used for industrial liquid 体, especially is 造纸, made process in high temperature liquid and electroplating, electrical chemical as in acid. alkali liquid 体. many electroplating industrial tube/pipe in using/adopting CPVC贮罐, pipe/tube and parts. also has pipeline, pipe fittings, 阀门, material sheet/plate and equipment, and other full use CPVC manufacturing system.
家 use electrical appliances manufacturing also 发现, CPVC良 good water property, solid has resistant property （达 to UL standards 94－SVA）, resistant liquid, resistant property, for/regarding 直接安装 in machine, machine inner electrical machine upper water 泵 说, combined requirements.
high degree heat resistant property, resistant property, 遇油脂也不 crazing, can use CPVC manufacturing automotive inner parts. this features make CPVC can use manufacturing cold water tube/pipe and water 盘.
solid has resistant property （ UL standards 94?SVA can property ）, and excellent chemical resistant features, UV resistant light property, resistant water and good property, make series new type Brand CPVC can use manufacturing printing machine outer housing/shell and base/seat and other type office machine parts.
also has low property CPVC material material, it meet/satisfy aviation specification 25．853款（A-1） has machine machine inner products hot value 必需符 combined speed rate most new requirements. meanwhile, this material material meet/satisfy 城市公共交通 tube/pipe 理局烟火准则 requirements. this low property material material products meet/satisfy inner A grade standards has low property can requirements. also has types deep color resistant gas new type Brand material material used for 农田灌溉方面. 总之, chlorine not only PVC原 has excellent property can, but also make polymer suitable for more high temperature degree lower, 因而, can metal or other price more engineering plastics.
