There are also more than the number of production companies (nearly 400), yields a miscarriage can be large (2.8 million tons), a small demand (2003 sales of 1.2 million tons country profiles), production can not take full advantage of the current situation in the industry, this industry PVC profiles contradictions, more than 20,000 tons of annual production capacity of less than 10 companies, uneven level of product quality pvc pipe production, inferior products still have a market, quality and technology industry standard is too low, is not conducive to technological progress, leading to substitute aluminum comeback. The high-end market (30%) were occupied by foreign brands, middle and low market unprofitable, intense competition, the final pattern has not yet formed. From the factory distribution, at 392 profiles manufacturers in the southeast region of 37%, 12%, Shandong, the central region of 17%, 19% in the Northeast, 15 percent in the western region. From the point of view of production capacity in 2003 the National Division capacity 2.8 million tons, 9% in Shandong Province in the central region of 1%, the Northeast 32% pvc pipe line, the western region of 7%, 39% in the Southeast region. Our PVC resin consumption is mainly concentrated in two areas south and east, Guangdong, Zhejiang, Fujian, Shandong and Jiangsu provinces, the total consumption of the country's total consumption accounts for about 70. 0% where the market demand in Guangdong and Fujian most, but production capacity, higher imports of polyvinyl chloride resin proportion; Jiangsu, Shandong and Zhejiang provinces PVC resin processing industry is relatively developed provinces accounted for consumption total domestic consumption of 34. 0%; North China sales balance. Pvc pipe in the future, along with the construction of the Midwest as well as large-scale development efforts to strengthen infrastructure, Midwest PVC resin consumption will gradually increase. PVC is the growth rate of 4% of the production and application worldwide. PVC growth in Southeast Asia is particularly significant, thanks to the Southeast Asian countries have carried out urgent infrastructure needs. In the three-dimensional surface film can produce the material of the material properties of ABS (acrylonitrile - butadiene - styrene) ABS is used for conveying drinking water, mud and chemicals. The most commonly used DWV (drain waste exhaust) applications. Unplasticized polyvinyl chloride (UPVC) and CPVC (chlorinated polyvinyl chloride after) having the entire operating temperature range within UPVC excellent chemical resistance, with a wide range of operating pressure belt. Due to the nature of long-term high-intensity, stiffness and cost-effectiveness, UPVC systems account for a large proportion of the plastic pipe installation. CPVC is resistant to many acids, bases, salts supply pvc pipe, paraffins, halogen and alcohols. This is not an anti-solvent, aromatic hydrocarbons and some chlorinated hydrocarbons. PP (polypropylene) Polypropylene is suitable for use in food, drinking water and ultra pure waters, as well as in the pharmaceutical, chemical and other industries. PE (polyethylene) polyethylene has been used successfully for many years drinking water and wastewater, hazardous waste, and safe transportation of compressed gas.
