Review of the development of China's plastic industry in 2006

distinguished guests and friends:

Hello! First of all, on behalf of the China Plastics Processing Industry Association, I have the honour to say hello to friends in the plastic industry media and thank you for your enthusiasm and support for the 21st China International Plastics and rubber industry exhibition! "2007 National Rubber and plastic Exhibition" will be held grandly at Guangzhou International Convention and Exhibition Center in Pazhou, Guangzhou on May. On this occasion, I will review the development of China's plastic industry in 2006, share the current development trend of the integration of plastics and life, and wish "2007 National Rubber and plastic Exhibition" another success and make new contributions to the development of China's and even the world's plastic industry

before Hyundai Automobile revealed the specific materials adopted, the global annual consumption of plastic reached 240 million tons, with an annual increase of about 4%; China's annual consumption of plastic is more than 400 million tons, and will continue to grow at an average annual rate of at least 8% in the next few years. Plastic has been integrated into the process of human social civilization and scientific progress since its birth. It is close to people's daily life. With its excellent comprehensive properties, it is widely used in many fields of the national economy and plays an important role in social progress and economic development. A large number of applications of plastics can save a lot of resources and energy than other materials. Plastic recycling is the inevitable choice to achieve the sustainable development of the plastic industry. As an environment-friendly material, plastics have been integrated with people and society, and have become the power carrier for the improvement of people's living standards and economic take-off. The history of plastic development has witnessed the harmonious development and closely related process of plastics, society, economy and people's life

I. the status of the plastic industry in the national economy China's plastic industry has developed rapidly, stably and healthily with the sustained prosperity of the national economy, forming a relatively complete industrial system, and becoming a new basic material industry on par with steel, cement and wood. Its application fields have far exceeded the above three industries. China's plastic industry has entered the ranks of the world's largest plastics countries. Plastic processing machinery, plastic products and plastic resin have ranked first, second and third in the world respectively, and have certain strength to participate in international competition. The industrial scale of "Chaoyang industry", with the plastic products industry as the core, has further expanded, and the main economic indicators have increased year by year; The technological innovation ability of the industry has been further enhanced, the number of enterprise technology R & D centers has been increasing, and several regional high-tech industrial clusters have been established; The industrial structure, enterprise structure and product structure have been continuously adjusted, and the industrial intensity has gradually increased; The overall advantages of the plastic industry have been further enhanced and strengthened, and the gap with the internationally developed countries is gradually narrowing. Some aspects have reached the world's advanced level, ushering in the "Eleventh Five Year Plan" key period of moving from a large country to an advanced power

the total output value of China's plastic industry doubled during the Tenth Five Year Plan period, showing a vigorous growth trend. In 2006, the first year of the eleventh five year plan, the development situation was also good:

the economic operation of China's plastic industry in 2006:

the output of China's five major synthetic resins in 2006 was 19.591 million tons, an increase of 18.9% year-on-year; The import volume was 10.376 million tons, a year-on-year decrease of 12.7%; Apparent consumption was 29.31 million tons, with a year-on-year increase of 6.1%. month. It is estimated that the apparent consumption of the five major synthetic resins will reach 35.5 million tons in 2006. Driven by the rapid development of downstream processing industry, the total amount of synthetic resin increased significantly, with a year-on-year increase of 16.75% (see Table 1)

in 2006, the output of plastic products in China was 25.182 million tons, with a year-on-year increase of 19.32% (see Table 2), showing the rapid and steady development of China's plastic industry in the first year since entering the "Eleventh Five Year Plan"

in 2006, the total industrial output value was 511.913 billion yuan, an increase of 26.10% year on year; The main business income was 493.193 billion yuan, an increase of 25.31% year-on-year; The total profit and tax was 32.796 billion yuan, an increase of 31.43% year-on-year; The total profit was 20.907 billion yuan, with a year-on-year increase of 34.85% (see Table 3), indicating that the economic operation of China's plastic industry is in good condition

II. Plastics have achieved remarkable results in saving resources, energy and recycling, and have great achievements

1 energy conservation, consumption reduction, energy conservation and resources, Building a conservation oriented society is a distinct theme of contemporary China's economic and social development. Plastic products industry belongs to the industry with high added value and low energy consumption. Plastic processing consumes electric energy and raw materials. Saving energy and materials is the inevitable choice for the plastic industry to reduce costs and develop harmoniously. With the continuous development of science and technology, plastic consumption reduction and energy saving have been greatly improved through advanced electronic automation technologies such as frequency conversion servo and the introduction of advanced equipment, which not only improves the productivity, but also saves labor resources. In terms of material saving, the purpose of saving materials is achieved through scientific material selection, material modification, multi-functional material development, thin-walled products and other ways. Through the direct recycling of machine heads and leftover materials, and the recycling of plastic after use, the resource saving and reuse are achieved, with remarkable results

reducing energy consumption is the goal that China's plastic industry has been striving to pursue. From the past flow proportional and pressure proportional control, to variable control, variable frequency control and servo control. The high efficiency of the injection molding machine is mainly reflected in its fast working pace and short product cycle, which is generally more than 24% higher than that in the past. In general, injection molding machines, extruders, hollow blow molding machines and other energy-saving technologies have developed quite rapidly

in the field of plastic products processing, energy conservation and consumption reduction should not only start from the aspect of plastic processing machinery, but also go deep into the energy-saving field of plastic raw materials and processing technology. First, the use of energy-saving raw materials can improve efficiency. For example, high melt flow index resin can obtain better fluidity at low temperature, which can significantly reduce energy consumption in processing and significantly shorten the molding cycle. Secondly, reasonable material selection can save costs. Reasonably select materials or add reinforcing materials, fillers, etc. to improve performance and save resin consumption. For example, composite plastics, fiber reinforced plastics, plastic wood composites, etc. are energy-saving raw materials. Thirdly, porous technology can reduce cost and increase efficiency. Foaming plastic products with light weight and good thermal insulation can be made by chemical or physical foaming. Its low density and good mechanical properties can greatly reduce the use of resin

$page break $2. Saving materials in many fields, the use of plastics not only saves resources and energy, but also saves materials. Plastic has a longer service life than steel and wood, but the cost does not increase much, which significantly reduces the consumption of resources and energy, and can meet various performance requirements at the same time; It not only saves a lot of other materials, but also can be recycled. Plastic processing is a low-energy, high-efficiency and pollution-free process, which can achieve cleaner production and comply with the national industrial development policy. For example, the biggest advantage of using plastics to make auto parts is to reduce the weight of the car, save costs and processes, and improve some performance of the car. For every 10% reduction in the weight of the car, the fuel consumption can be reduced by 6% - 8%. The use of plastic parts can reduce the mass of parts by about 40% and save materials. The average plastic consumption per vehicle in developed countries has exceeded 100 kg, while that in China is only about 70 kg, so there is ample room for development

3. Building energy conservation, construction, industry and transportation are the three major areas of energy consumption in China. Buildings account for 1/4 of China's total energy consumption, of which external wall insulation, roof insulation, and door and window heat dissipation account for 50% of the energy waste of houses. Therefore, heating in the north in winter and cooling in the south in summer are a great waste of energy. In terms of building thermal insulation performance, the energy consumption of doors and windows in China is 2.2 times that of developed countries, and the energy consumption of exterior walls is 4 times that of developed countries. At present, the state requires that the heat transfer coefficient of external walls be reduced from 0.8~1.16 to 0.45~0.6, windows from 3.5 to 2.8, and the standard coal consumption of energy-saving houses from 25.2kg/m2 to 8.82kg/m2. Polyvinyl chloride (PVC) plastic doors and windows are energy-saving, material saving, weather resistant and corrosion resistant, which meet the requirements of environmental protection and reduce energy consumption. Due to its poor thermal conductivity and multi chamber structure, the plastic profile has excellent thermal insulation performance. The special implantable devices designed by polymer chemists, plastic engineers and genetic biological scientists are used as visceral substitutes. The energy consumption of heating with plastic part small expansion doors and windows can be saved by about 17% compared with ordinary steel doors and windows. There is also a lot of energy waste in industry and transportation, and plastic products are promising in these fields. Rigid polyurethane foam (RPUF), expandable polystyrene foam (EPS), continuous extruded polystyrene foam (XPS) and other foams as building energy-saving materials have been technically mature, and their thermal insulation performance is excellent. In building, energy-saving materials are mainly used in the walls, roofs, doors and windows, floors and other places of housing construction. Foamed plastics are of great use. Among them, microporous plastics (109~1015 holes in 1cm3) have excellent properties (impact strength is increased by 6~7 times, fatigue life is increased by 4~7 times). If they can be industrialized as soon as possible, it will be a great breakthrough in energy conservation and heat insulation. By 2010, China's urban buildings should meet the design standard of 50% energy saving, and the maintenance and insulation should undertake about 70% of the energy-saving tasks, of which the wall accounts for another 2/3. China's new construction area is 2billion square meters every year, and about 40billion square meters of high energy consuming buildings need to be equipped with insulation layers, which provides a huge market for plastic insulation materials. About 49% of building insulation materials in developed countries such as Europe and the United States are polyurethane materials, but in China, this proportion is less than 10%. Energy saving is also reflected in the development of some new materials
