Thermal insulation materials and products is an important factor affecting the building energy efficiency. The development and application of building heat preservation material is becoming more and more popular in the world. After 1970s, foreign countries generally pay attention to the production of heat preservation material and the application in the construction, and strive to reduce the energy consumption, thereby reducing environmental pollution and greenhouse effect. Foreign heat preservation material industry has a long history, building energy conservation with heat preservation material, and the new type of insulation material is also emerging.
Before 1980, China insulation materials, the development is very slow, but China insulation materials industry after 30 years of efforts, especially after nearly 20 years of rapid development, many products from scratch, from single to diversification, quality from low to high, has formed take expansion perlite, mineral wool, glass wool, foam, refractory fiber, calcium silicate insulation products, such as the relatively complete variety of industry.
2006 1-12 months, China's imports of mineral wool; expansion of mineral materials; heat insulation or sound insulation materials for the amount of 13110148 kg, with the exchange of $29396269; 2006 1-12 month, China's exports of mineral wool; expansion of mineral materials; heat insulation or sound insulation materials for the number of 323873323 kg, with the exchange of $141929418.
2007 1-10 months, China's imports of mineral wool; expansion of mineral materials; heat insulation or sound insulation materials for the amount of 12844531 kg, with the exchange of $28133066; 2007 1-10 month, China's exports of mineral wool; expansion of mineral materials; heat insulation or sound insulation materials for the number of 293114475 kg, with the exchange of $148816708.
Polyurethane material is the best performance of the world's insulation materials. Hard polyurethane has many excellent properties, in Europe and the United States is widely used in the building of the roof, walls, ceilings, floors, doors and windows, and other insulation materials. Europe and the United States and other developed countries of the building insulation materials about 49% of the polyurethane material, and in China the proportion is still less than 10%. Therefore, there is still a lot of room for the development of polyurethane materials in China.
China building energy saving materials market, especially building insulation materials. The energy loss of Chinese housing is about 50%; the roof is about 10%; the windows and doors are about 25%; the basement and the ground is about 15%. China Building in 2010 to achieve energy saving rate of 50%, the need for a comprehensive renovation of the building facades, wall heat preservation material market will increase significantly.
Type and application range of heat preservation material
Heat preservation material has many kinds, the application scope is also very wide.
The more commonly used are: glass wool, heat insulation blanket, insulation foam glass, polyurethane, etc..
Uses of glass wool products:
Air conditioning heat insulation, air pipe insulation, steel structure heat preservation, boiler heat insulation, dust collector, steam pipe insulation, etc..
