pvc plastic pipe processing, sea Widex (certified), pvc plastic pipe fittings provided by Qingdao Rubber Material Co. Widex. Widex Qingdao Rubber Material Co., Ltd. (www.haihuidaxiangsu.com) is specialized in "PVC profiles, seals, ABS extrusion profiles, PVC raw material" of the enterprise, the company of "honesty, hard service" concept, for You provide the most quality products and services. Welcome to inquire! Contact: Zhao Shuang. PVC (full name Polyvinylchlorid), the main component of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table top layer mask is painted, the main ingredient in the middle of the PVC, the lower is the adhesive-backed. It is loved by the world, is quite popular and is also widely used as a synthetic material. It ranks second in the global use of a variety of synthetic materials. According to statistics, in 1995 only one year supply pvc plastic pipe fittings, PVC production capacity in Europe, there are about five million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption by an average of 1.4 million tons. PVC pipe (PVC-U pipes) hard PVC pipe is made of PVC resin and rear stabilizers, lubricants, etc. with the law by hot extrusion, was the first to get the development and application of plastic pipe. PVC-U pipe corrosion resistant, easy bonding, low price, hard, but because there are PVC-U monomers and additives exudation, applies only to transport temperature does not exceed 45 ℃ water supply system. Plastic pipe used to transport drinking water applications, wastewater, chemicals, heating fluid and coolant, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. Suspension polyvinyl chloride PVC resin body [palyvinyl chloride (bulk polymerization)] China has production pvc plastic pipe fittings, Sichuan Yibin Tianyuan, 内蒙古海吉 two companies, the method of product transparency and insulation than other methods. Solution polymerization of PVC resin used for surface coating on. At low temperature 20 ~ 30 ℃ or below 0 ℃ suspension, emulsion polymerization or bulk polymerization, both said low temperature. Low molecular weight polymeric PVC high crystallinity and high structural regularity and good pvc plastic pipe manufacturers, high glass transition temperature, heat resistance, solvent resistance. But difficult to process than ordinary PVC, lower impact strength, used for fiber and specialty plastics. The resulting emulsion PVC production called Emulsion PVC (Emulsion poly-merixation). It is a paste resin, high molecular weight, smaller particles. Emulsion PVC Model RH-xy, where R- emulsion method; H- paste resin; x- absolute viscosity resin ene solution; y- paste viscosity. x points 1,2,3 type, a type of absolute viscosity of 2.01-2.4mPa · s pvc plastic pipe products, type 2 absolute viscosity of 1.81 ~ 2.00mPa · s, 3 type absolute viscosity of 1.60 ~ 1.80mPa · s. y points Ⅰ, Ⅱ, Ⅲ number, number Ⅰ paste viscosity of not more than 3,000mPa · s, Ⅱ No. paste viscosity of 3000 ~ 7000mPa · s, Ⅲ number paste viscosity of 7,000 ~ 10,000mPa · s.
