Currently pvc plastic pipe, plastic building materials and other products from the interior pieces began to structural, functional pieces direction. Plastic flooring, wall decoration pieces maintained a steady growth in sales, polymer construction template, waterproof material, wall supports, wall insulation panels, plastic bricks strengthen more and more applications pvc plastic shaped pipe, which increases speed is more than the plastic pipe. Expected in the next 5-15 years, under the guidance of various national building energy efficiency policies, plastic building materials market is expected to be more rapid development. By 2015, the Chinese variety of architectural plastic pipes and plastic doors and the average market share will reach 50% and 30%, respectively. Pvc plastic pipe demand price, variety of architectural plastic pipes and plastic windows and doors plus polymer waterproof materials, decoration materials, insulation materials and other plastic products used in construction, total demand is expected to reach 10 million tons. PVC melt temperature during processing is a very important process parameters, if this argument would lead to inappropriate material decomposition problem. PVC is rather poor flow characteristics, the process is very narrow range. Especially large molecular weight PVC material more difficult to process (this material is usually added to improve the flow characteristics of lubricant) pvc plastic pipe manufacturers, it is often used are small molecular weight PVC material. PVC contraction rate is very low, typically 0.2 to 0.6%. Injection molding conditions melting temperature: 185 ~ 205 ℃ mold temperature: 20 ~ 50 ℃ injection pressure: can be as large 1500bar holding pressure: can be as large as 1000bar injection speed: To avoid material degradation, the general use of the injection speed considerably. pvc plastic pipe manufacturers, sea Widex (certified), pvc plastic pipe provided by Qingdao Rubber Material Co., Widex.
