(Summary description)1) Rigid polyvinyl chloride (UPVC) pipe, 2) Chlorinated polyvinyl chloride (CPVC) pipe, 3) Polyethylene (PE) pipe, 4) Cross-linked polyethylene (PE-X) pipe, 5) Type three Polypropylene (PP-R) pipe, 6) Polybutene (PB) pipe, 7) Engineering plastic (ABS) pipe, 8) Glass fiber reinforced plastic (RPM) pipe, 9) Aluminum plastic composite (PAP) pipe, 10) Production of steel-plastic composite (SP) pipes, etc., plastic pipes and fittings. Use is a cross-industry and cross-departmental system engineering. The raw materials are petrochemicals. Provide the required special materials, the manufacturing will be arranged separately in the industrial and building materials industry (as a new type of building materials), and the products will be used in construction (residential) and agriculture and urban infrastructure. In 2000, the world's total output of plastic materials was 163 million tons, an increase of 3.6% over 1999. In 2000, China had 10.8 million tons of synthetic resins, and the average annual growth rate of synthetic resin production in the past ten years was over 15%. In 2001, the output of plastic products in my country exceeded 10 million tons, (including the total output of enterprises with a scale of -F, which was approximately 22 million tons). From January to July 2002, the output of plastic products by enterprises above the designated size was 7,627,500 tons, a year-on-year increase of 13.9%. The rapid development of China’s plastic product processing industry has achieved world-renowned brilliant achievements thanks to the rapid development of the raw and auxiliary material production industries used in the production of plastic products, as well as the processing machinery and equipment and mold manufacturing industries. At the same time, the rapid development of the plastic product processing industry has also greatly increased Promoting the development of related industries, the synthetic resin, auxiliary and additive production, processing machinery and mold manufacturing industries with the plastic product processing industry as the core promote and coordinate the development of each other, forming a grand blueprint for the development of China's plastics industry. Supply of main raw materials: In 2001, my country produced 4.81 million tons of ethylene raw materials, a year-on-year increase of 2.3%. From January to July 2002, the cumulative output of plastic resins and copolymers of enterprises above designated size was 7.562 million tons, a year-on-year increase of 9.5%. The production of ethylene raw materials was 2.986 million tons, year-on-year An increase of 5.2%. my country's domestic plastic raw materials are in short supply, and the gap is made up by imports. The production status of ethylene in my country is that the quantity of ethylene cannot meet the market demand, and imports have reached 50% in the past five years; the second is that the quality of the variety cannot meet the market demand, and a large number of special varieties and special materials rely on imports. The third is that the scale of ethylene is far from reaching the scale of the world economy. Level. my country's ethylene equivalent demand will grow at a rate of 8.5%. By 2005, my country's total ethylene equivalent demand will reach 15 million tons. After transformation, expansion and new construction, the ethylene production capacity will reach more than 9 million tons, and the self-sufficiency rate will reach 60%. The production capacity of polyethylene is 2.59 million tons per year (low density is 703,000 tons, high density is 855,000 tons, and linear low density is 1.035 million tons). The world production capacity of polyethylene is 59.8 million tons/year. In 2005, the domestic market satisfaction rate of special synthetic resin materials reached more than 40%. The consumption of plastic raw materials is shown in the table below.
