China plastic pipe industry in the development, some problems are increasingly apparent. Especially less variety of raw materials, the quality of instability, price volatility, lack of special, product quality can not guarantee the supply of PVC plastic, product structure, production scale is unreasonable, production equipment, product quality is generally poor, chaotic management, standards, norms, Atlas, quotas and other serious lag, supporting poor, can not meet the development needs and the lack of practice tests and other factors severely restricted the further development and quality improvement industry. Therefore, China plastic pipe companies must seize new developments, attention production of raw materials, research and development, regulate industry positioning, improve the quality management measures to regulate the sales market, strengthen macro-control and guidance, develop, and improve the relevant standards and technical and economic policy PVC plastic wholesale, strengthen cooperation and improve the sound of plastic piping systems, the only way to be invincible in the new situation. PVC plastic is a liquid vinyl chloride monomer (VCM) by suspension polymerization, emulsion, bulk or solution process PVC plastic prices, including suspension polymerization process mature production technology, simple operation, low production costs, product variety, application wide range, has been the main method of production of PVC resins, PVC production facility in the world approximately 90% of the proportion (in the world production of PVC homopolymer also accounted for about 90% of the scale). PVC plastic emulsion method was followed for the production of PVC paste resin. Its polymerization by a free radical initiator, the reaction temperature is generally 40 ~ 70OC, reaction temperature and concentration of the initiator of the polymerization reaction rate and the molecular weight distribution of PVC resin great influence.
