Compared with the traditional plastic pipe cast iron pipe, galvanized steel, cement pipes and other pipes, with energy and materials, environmental protection, lightweight, high strength, corrosion resistance, smooth wall without fouling, simple construction and maintenance, long life and other advantages of injection products, widely used in building water supply and drainage, urban and rural construction, municipal, industrial and agricultural areas of water supply and drainage, city gas, electricity and cable jacket, industrial fluid transport, agriculture and irrigation. In recent years, with the construction, municipal engineering, water conservancy, agriculture and industrial sectors increasing market demand, China plastic pipe industry has shown a trend of rapid development. 2009 plastic pipe production capacity of 5.804 million tons, an increase of 18.9% from January to September 2010 production of 5.528 million tons of plastic pipe, an increase of 28.23%. Meanwhile, with consumer products and environmental protection, health, durability and other aspects of the quality requirements continue to increase, China's plastic pipe production increased at the same time, the continuous improvement of product quality, technological progress continues to accelerate industry, brand-scale enterprises continue to increase, new materials, new structures are emerging breed injection product prices, advanced system design concepts emerging, product functionality more obvious applications to be further widened. Analysts believe that China is currently the proportion of plastic pipe market share in all of the pipeline has been over 30%. Plastic profiles for its excellent thermal insulation properties of building materials is listed as one of China's key development. In the plastic profile production process, what issues need attention in order to ensure the quality and craft profiles. Now we come to understand the plastic profile additives are there? Additives a plastic profiles: impact modifiers, such as the production of plastic profiles without impact modifier, plastic profiles will be very brittle, a little collision, easily broken. Commonly used in the production of plastic profiles impact modifier modifier consists of the following three categories: chlorinated polyethylene, polyacrylates, ethylene - vinyl acetate copolymer. Plastic profiles aid II: heat stabilizers plastic profiles are heat-sensitive plastic, so the plastic profile production machining, heat stabilizers is essential. Thermal stabilizers in PVC can absorb salts of the decomposition products HCL injection technique, it can delay the decomposition rate of decomposition of the plastic and the time is prolonged, the production of plastic profiles for the most commonly used lead salt complex, the thermal stability of high efficiency, price inexpensive.
