1 - December 2008, the Chinese plastic sheet, pipe, profile output value of 214.3 billion yuan, up 32.29% from a year earlier, while plastic industry as a whole is hit by the financial crisis in 2008, but even plastic building materials field under the serious situation of financial crisis, remained increased significantly.

With plastic as the raw material made of all kinds of plastic building materials, usually composed of many materials, including polymers (or synthetic resin) is the main component, in addition, according to the need of plastic building materials of all sorts of special performance and plastic building materials of various special environment, can add all kinds of auxiliary materials, such as packing, plasticizer, lubricant, stabilizing agent, colorant, etc., to become a good performance of plastic. The plastic materials of our country are roughly divided into: plastic sheet, plastic tube and plastic profile.

Plastic sheet: widely used in application

Plastic (plastic sheets) are made of plastic as the raw material plate, a large number of used in construction, chemical industry, used in chemical industry, environmental protection, building plate with wear-resistant, resistant to vibration, corrosion resistance, recycled, strength, anti-aging, waterproof, moistureproof, not changeful form, repeated use, etc. And now the hard plastic plate for the bottom, can also recycle the processing, greatly reduce the cost. Especially the features of ultra-high molecular weight polyethylene, it is a kind of optimal system performance engineering plastics, such as plate with high wear resistance, impact resistance, low friction coefficient, good self-lubricating properties, good low temperature resistance, resistance to chemical corrosion, etc. As a kind of high performance thermoplastic engineering plastic, ultra-high molecular weight polyethylene in early development, mainly used in the textile, paper making, food industries, as the technology progress, can use different processing method for the production of various kinds of products, thus expanding application fields. At present, in addition to the above applications, there are important applications of mining machinery, construction machinery, transportation machinery, materials and other cutting-edge technologies such as atomic energy. Abroad, ultra-high molecular weight polyethylene has been widely used in various fields.

Plastic plate in car interior trim and interior now has a wide range of applications, in September 2008, Elizabeth foundation innovation plastic for Lexan XHR6000 developed a new type of plate sheet Boltaron 9915 fsth1 has aesthetic appeal, in November the same year, queen Elizabeth foundation innovation have developed a new type of plastic layer type 9 Thermoclear Lexan * * plate, this new type of external Windows solution can not only help customers to reduce the cost of heating and cooling, can also reduce energy consumption and co2 emissions to benefit the environment. Now plastic sheet material toward set beautiful, practical in one body direction development, functional aspect is toward more professional, special function direction expands!

Plastic tubing: the growing boom in the crisis

In recent years, plastic pipes play an increasingly important role in the construction of urban water supply and drainage network. Compared with the traditional cast iron pipe, the plastic pipe has a light weight and long service life. Generally speaking, the service life of plastic pipe is more than 50 years, which basically achieves the same service life as the building. In some special fields, plastic pipe are very large, such as the current most eye-catching radiant floor heating industry, people - Xa or PE - RT with PE pipe as heat pipe, through the floor radiation heating the whole room, has the advantages of comfortable safety, environmental protection and energy saving, has gradually become the first selection of the northern region winter heating.

At the same time, the plastic pipe to further broaden the application area, in addition to the municipal and building to, drainage pipeline, agricultural, water supply, irrigation and drainage pipeline continues to grow, the rural drinking water, solar water pipe, municipal sewage, ground source heat pump pipeline, communications, electricity, gas, heating, medical and other industries the application of a huge increase in proportion. & other; 11th five-year plan & throughout; During the period, the annual demand of the plastic pipe for construction in China is about 5 billion meters. By 2010, China's plastic pipe production will reach 4.5 million tons, and by 2015, it will reach 6 million tons, when China will become the largest plastic pipe production country in the world.

So rapid development momentum, and various areas and using the environment requirements, make plastic pipes in new varieties, new structures, new materials, new technology, new technology and patent development more and more. In addition to PE, PE - X, PB, pipe, corrugated pipe and other varieties have a great progress, high temperature resistant polyethylene pipe (PE - RT), plastic composite pipe (such as HLDPE drain, mute, etc.), plastic composite pipe and all kinds of metal materials and composite materials of corrugated pipe, circular ribs, winding pipe and other new type pipe also rapid development.

But at the same time also want to see, plastic pipe industry in our country, there are some adverse factors restricting the development, such as the market competition of malignant change leads to low prices, raw material import dependency, new products and new technology application, slow, etc., especially in the current global economic crisis to plastic pipeline industry development impact is very large. In order to speed up the development of plastic pipe industry in China, the author suggests that the industry association should play an active role in providing services and support to enterprises. Accelerate China's raw material development speed, regulate industry self-discipline. To establish strict quality constraints mechanism, make the high quality, high technology content products enterprise has become the mainstream in the market, but also make construction enterprises to grasp more advanced technology, so as to enhance the overall effect of use of the product.

Plastic profile: development of functional and high documentation

Plastic profile is mainly used to make plastic steel doors and Windows. It is the fourth generation of new energy-saving products after wood, steel and aluminum. At present, the annual production capacity of plastic profiles in doors and Windows of our country is nearly 4 million tons, and the actual sales volume is close to 2 million tons per year. Hormone of anti-war plastic different profile and door industry, which greatly promoted the pace of chemical building materials product application in our country, for our country to save energy and resources, has made a great contribution to the economic construction of our country. At the same time, it has played a great role in improving and improving the living environment of our people. However, the various contradictions and imbalance in the rapid development have become the important factors restricting the healthy development of the industry. The first two years were affected by the internal and external environment, and the price inversion in the industry was a blow to the industry, which has not been recovered.

According to the ambient temperature of different areas, the requirements of plastic profiles are different. In the cold and cold regions, it is necessary to increase the anti-impact modifier or CPE with new anti-impact modifier to improve the impact performance of plastic profiles. In areas with high intensity of heat and ultraviolet radiation, the dosage of titanium dioxide and uv absorber should be increased appropriately to improve the anti-aging properties of plastic profiles. In high-rise buildings in coastal areas, A and B wall thickness (2.8mm or 2.5mm) should be used to improve the anti-wind pressure performance of plastic doors and Windows.

With the development and promotion of plastic doors and Windows, especially in the developed areas of the south coast in recent years, plastic doors and Windows have begun to develop into functional and high documentation. And the antibacterial plastic profile contains huge market power. It should be noted that, with the increase of the function of doors and Windows, the proportion of all kinds of accessories in the cost of doors and Windows will be greatly improved, some even more than the cost of profiles in doors and Windows.

To sum up, the products such as plastic profile, plastic tube and plastic sheet have formed a huge industrial chain of chemical building materials in China. Only plastic profiles have the capacity to produce 2.8 million tons a year and enter the ranks of plastic countries. It is estimated that in the next five to 15 years, China will have more than 1 billion square meters of completed construction area every year, and the market of plastic building materials will be able to develop more rapidly under the guidance of various building energy conservation policies in the country. By 2015, the average market share of all kinds of plastic pipes and doors and Windows in China will be 50% and 30% respectively. The demand side of various construction plastic pipes and plastic doors and Windows and the polymer waterproof materials, decoration materials, insulation materials and other construction plastic products, the total demand is about 10 million tons. The plastic building materials industry is booming, and the vast majority of enterprises should seize this opportunity to elevate the Chinese plastic construction industry to a new height.

Today, plastic building materials in China has stepped into the world's advanced plastic power, despite the global financial crisis, but the development of plastic building materials are still developing at a fast pace. For the current plastic building materials industry, the main thing is to do the following: accelerate industrial structure adjustment, accelerate the construction of modern enterprise system; We should pay more attention to the development of human resources and improve the overall quality of the whole industry. We should rely on scientific and technological progress to accelerate industrial upgrading and technological innovation. We should constantly adjust the product structure and improve the level of equipment technology. We should strive to create brand products and implement sustainable development strategy. We should keep abreast with The Times, and enjoy rapid and steady and healthy development in the fierce competition of domestic and foreign markets.
