Plastic profiles due to the huge market demand and broad prospects for development in recent years has been the rapid development of our country, because of the intensity of competition in the market, all plastic machinery manufacturers are considered a problem, how to improve the plastic profiles under the premise of ensuring product quality productivity and product qualification rate, the maximum capacity of play equipment to reduce production costs. [1] The growing competition in the industry of plastic profiles, plastic profiles large mergers and acquisitions integration and capital operation is becoming more frequent, more and more attention to the domestic producers of plastic profiles of outstanding research on the industry market, especially for enterprise development environment and customer needs depth study of the trend change. Because of this, a large number of outstanding domestic brands of plastic profiles rapid rise, has become the industry leader in plastic profiles! PVC is an amorphous polymer, there is no obvious melting point, heated to 120 ~ 150 ℃ when plasticity. Because of its poor thermal stability of PVC plastic pipe fittings, at this temperature contains small amounts of HCl released, prompting further decomposition, it must be added to the alkaline stabilizer and HCl and inhibit its catalytic cracking reactions. Pure PVC is a rigid plastic PVC pipe products, the need to add the right amount of plasticizer to make it soft for different products need to join, such as UV absorbers, fillers, lubricants, pigments, preservatives and other additives in order to attain good PVC products performance. And other like plastics plastic PVC pipe, resin properties determine the quality of products and processing conditions. Of PVC, the resin properties and processing related are: particle size, thermal stability, molecular weight, fish eyes, bulk density, purity and foreign matter, porosity. There paste for PVC paste viscosity and gelling properties, should be determined to try, easy to grasp the processing conditions and product quality.
