          Analysis of development situation in the crisis of plastic building materials

          2015-05-05
          Under the premise of the country's vigorous promotion of environmentally friendly building materials such as environmental protection and sustainable development, plastic building materials continue to develop and grow like a rising star.

          In recent years, the increase in state investment in infrastructure has also greatly promoted the development of plastic building materials. As plastic building materials will become new consumption hotspots and economic growth points, the varieties of plastic construction products will be gradually serialized, matched and standardized, and the requirements for environmental protection and energy saving and the promotion of application will increase. Various plastic pipes, doors, windows, and polymers The demand for waterproof materials, decorative materials, thermal insulation materials and other building plastic products will increase significantly.
          With an average annual growth rate of more than 15%, China's plastic building materials industry has become the second largest pillar industry after the packaging industry. In recent years, China's plastic building materials industry has accelerated the pace of R & D and promotion and application. The industry's production scale has continued to expand and technology has steadily improved. Especially, plastic profiles and pipes have entered a stable and mature growth period and become the best-used plastic building materials. . More than 30% of China's regions have applied new plastic pipes , and some fast-growing provinces and cities have reached 90%. In some cities and towns in the three provinces of Northeast China and Inner Mongolia, more than 40% of newly built houses use plastic windows and doors, and more than 80% of new houses in Qingdao and Dalian use plastic windows. The scale and output value of plastic plates, tubes and profiles in the past three years are as follows:
          From January to December 2006, the enterprises above the designated size in the manufacturing industry of plastic plates, pipes and profiles in China have realized a total industrial output value of 125,714,106 thousand yuan, an increase of 30.35% over the same period of the previous year; a cumulative product sales income of 120,739,577,000 yuan, a year-on-year increase During the same period, it increased by 29.09%; the cumulative total realized profit was 5,905,211,000 yuan, an increase of 32.51% over the same period last year.
          From January to November 2007, the enterprises above the designated size in the plastic plate, tube, and profile manufacturing industry in China have realized a total industrial output value of 149,891,272,000 yuan, an increase of 29.20% over the same period of the previous year; a cumulative product sales income of 146,609,859,000 yuan, a year-on-year increase During the same period, it increased by 32.34%; the cumulative total realized profit was RMB 7,906,131 thousand, an increase of 47.18% over the same period last year.
          From January to December 2008, the total output value of China's plastic plates, tubes and profiles reached 214.3 billion yuan, an increase of 32.29% year-on-year. Although the plastics industry as a whole was affected by the financial crisis in 2008, the plastic building materials sector was in severe situation even in the severe financial crisis. It still maintained a substantial growth.
          Various plastic building materials made of plastic are usually made of many materials, of which high-molecular polymer (or synthetic resin) is the main component. In addition, according to various special properties of plastic building materials and Various special environments for the application of plastic building materials, various auxiliary materials such as fillers, plasticizers, lubricants, stabilizers, colorants, etc. can be added in appropriate amounts in order to become plastics with good performance. China's plastic building materials are roughly divided into: plastic plates, plastic pipes and plastic profiles.
          Plastic sheet: excellent performance in a wide range of applications
          Plastic sheet (plasticsheets) is a sheet made of plastic. It is widely used in construction and chemical industries. It is used in chemical industry, environmental protection, and construction board. It has abrasion resistance, vibration resistance, corrosion resistance, recyclability, high strength, and aging resistance. , Waterproof, moisture-proof, not easy to deform, repeated use and so on. In addition, the hard plastic pallets currently replaced can be recycled and processed, which greatly reduces costs.
          Among them, the ultra-high molecular weight polyethylene is particularly outstanding. It is an engineering plastic with excellent performance, such as high abrasion resistance, impact resistance, low friction coefficient, good self-lubrication, and excellent low temperature resistance. , Chemical resistance, etc.
          As a high-performance thermoplastic engineering plastic, UHMWPE was mainly used in industrial sectors such as textiles, papermaking, and food in the early stages of development. With the continuous advancement of technology, various products can be produced by different processing methods. Therefore, the application field is constantly expanding.
          At present, in addition to the above-mentioned applications, cutting-edge technologies such as mining machinery, construction machinery, transportation machinery, material linings, and atomic energy have also gained important applications. Abroad, UHMWPE has been widely used in various fields.
          Plastic sheets are now widely used in automotive interiors and aircraft interiors. In September 2008, SABIC Innovative Plastics developed a new aesthetically attractive Boltaron9915FSTH1 sheet for LexanXHR6000 sheet.
          In November of the same year, SABIC Innovative Plastics developed a new 9-layer Lexan * Thermoclear * sheet. This new exterior window solution not only helps customers reduce heating and cooling costs, but also reduces energy consumption and carbon dioxide emissions. To benefit the environment. Now the plastic sheet is developing in the direction of integrating beauty and practicality, and the function is expanding towards more professional and special functions!
          Plastic pipes: more and more booming in the crisis
          In recent years, plastic pipe has played an increasingly important role in the construction of urban water supply and drainage pipe networks . Compared with traditional cast iron pipes , plastic pipes have a light weight and a long service life. Generally speaking, the service life of plastic pipes is more than 50 years, which has basically reached the same service life as buildings. In some special fields, the application of plastic pipes is very huge. For example, the most eye-catching floor radiant heating industry, people use PE-Xa or PE-RT pipes as heating pipes, which heat the entire room through floor radiation, which is comfortable, safe, and environmentally friendly. Advantages such as energy saving have gradually become the first choice for winter heating in northern areas.
          At the same time, the application field of plastic pipes has been further expanded. In addition to municipal and building water supply and drainage pipes, agricultural (water supply, irrigation and drainage) pipes continue to grow, rural human and livestock drinking water transformation, solar water pipes, municipal sewage, ground source heat pump transportation pipes, communication , Electric power, gas, heating, medical and other industries increased the proportion of applications.
          During the "Eleventh Five-Year Plan" period, China's annual demand for construction plastic pipes is about 5 billion meters. By 2010, China's plastic pipe output will reach 4.5 million tons, and by 2015 it will reach 6 million tons. By then, China will become the country with the largest plastic pipe production in the world.
          Such rapid development and the requirements of various fields and the use environment have led to the development of more and more plastic pipes in new varieties, new structures, new materials, new technologies, new processes and patent projects. In addition to PE, PE-X, PB, composite pipes, corrugated pipes and other varieties have made great progress, high temperature resistant polyethylene pipes (PE-RT), plastic composite pipes (such as HLDPE, silent drainage pipes, etc.), plastic metal composite pipes And various materials and composite materials such as bellows, annular ribs, winding pipes and other new types of pipes are also rapidly developing.
          But at the same time, we must also see that China's plastic pipeline industry still has some unfavourable factors that restrict its development, such as the vicious market competition leading to low product prices, high dependence on raw material imports, and the slow promotion and application of new products and technologies. It is the current global economic crisis that has greatly affected the development of the plastic pipe industry.
          In order to speed up the development of China's plastic pipe industry, the author suggests: give play to the functions of industry associations and actively provide services and support for enterprises. Speed up the development of raw materials in China and standardize industry self-discipline. It is necessary to establish a strict quality restraint mechanism, so that enterprises with high quality and high product technology content become the mainstream of the market, and construction enterprises should be equipped with more advanced technologies to improve the overall use of products.
          Plastic profiles: development towards functional and highly documented
          Plastic profiles are mainly used for plastic steel doors and windows. They are the fourth generation of new energy-saving products after wood, steel and aluminum. At present, the annual production capacity of plastic profiles in China's door and window industry is close to 4 million tons, and the actual production and sales volume is also close to 2 million tons / year. The anti-war plastic profile and the door and window industry have greatly promoted the application of chemical building materials in China, saving energy and resources for China, and making great contributions to China's economic construction. At the same time, it has played a huge role in improving and improving the living environment of our people. However, various contradictions and imbalances in the rapid development process have also become important factors restricting the healthy development of the industry. Due to the impact of the internal and external environment in the past two years, the price inversion phenomenon in the industry has caused a blow to the industry, and has not yet recovered.
          Depending on the ambient temperature in different regions, the requirements for plastic profiles are also different. In severe cold and cold regions, an appropriate impact modifier should be added or a new impact modifier ACR should be used instead of the original impact modifier CPE to improve the impact resistance of plastic profiles. In hot and high ultraviolet radiation areas, the dosage of titanium dioxide and ultraviolet absorber should be appropriately increased to improve the anti-aging performance of plastic profiles. In high-rise buildings in coastal areas, special profiles with wall thickness (2.8mm or 2.5mm) and larger cavities should be used to improve the wind pressure resistance of plastic doors and windows.
          With the development and promotion of plastic doors and windows, especially in recent years, in the coastal economically developed areas of China, plastic doors and windows have begun to develop into functional and highly documented development. The antibacterial plastic profile has huge market momentum. It should be noted that as the functions of doors and windows increase, the proportion of various accessories in the cost of doors and windows will increase significantly, and some even exceed the cost of profiles in doors and windows.
          In summary, products such as plastic profiles, plastic pipes, and plastic sheets have formed a huge chemical building material industry chain in China. Only plastic profiles have a production capacity of 2.8 million tons per year, entering the ranks of major plastics countries.
          It is estimated that in the next 5-15 years, China's annual construction area will exceed 1 billion square meters. Under the guidance of various national building energy conservation policies, the plastic building materials market is expected to develop more rapidly. By 2015, the average market share of various construction plastic pipes and plastic doors and windows in China will reach 50% and 30%, respectively. On the demand side, various construction plastic pipes and plastic doors and windows are coupled with polymer waterproof materials, decorative materials, thermal insulation materials and other construction plastic products. The total demand is about 10 million tons. The plastic building materials industry is flourishing. Enterprises should seize this favorable opportunity to elevate China's plastic building materials industry to a new height.
          Today, China's plastic building materials have entered the ranks of the world's advanced plastics countries. Despite the global financial crisis, the development of plastic building materials is still developing at a rapid pace.
          For the current plastic building materials industry, the main points are as follows: to speed up the adjustment of industrial structure and the construction of modern enterprise systems; to pay more attention to human resource development and improve the overall quality of the entire industry; to rely on scientific and technological progress to accelerate industrial upgrading and technological innovation ; We must continuously adjust the product structure and improve the equipment technology level; We must vigorously strive for creating brand-name products and conscientiously implement the strategy of sustainable development; we must unite with one's ethics, advance with the times, and obtain sustained rapid, stable, and healthy development in the fierce domestic and foreign market competition !!
