中国保温材料的发展（Development of thermal insulation materials in China） Development of thermal insulation materials in China Heat insulation materials and products are important factors affecting building energy efficiency. More and more attention has been paid to the development and application of building thermal insulation materials all over the world. Since 1970s, foreign countries have paid much attention to the production and application of thermal insulation materials, and have made great efforts to reduce the consumption of energy, so as to reduce environmental pollution and greenhouse effect. Foreign insulation materials industry has a long history, the building energy saving thermal insulation materials accounted for the vast majority, and new thermal insulation materials are also emerging. Before 1980, the development of insulation materials Chinese is very slow, but Chinese thermal insulation material industry after 30 years of efforts, especially after nearly 20 years of rapid development, many products from scratch, from single to diversification, from low to high quality, has been formed from expanded perlite, mineral wool, glass wool, foam, fiber, refractory calcium silicate insulation products as the main varieties of relatively complete industry. In 2006 1-12 month, China imports of mineral cotton; expansive mineral materials; the quantity of heat or sound insulating material iskg, with the Department of 1-12 months of 2006, Chinese mineral cotton export expansion; mineral materials; quantity of heat or sound insulating material is 323873323 kg, with the Department of $141929418. In 2007 1-10 month, China imports of mineral cotton; expansive mineral materials; the quantity of heat or sound insulating material iskg, with the Department of 1-10 months of 2007, Chinese mineral cotton export expansion; mineral materials; quantity of heat or sound insulating material is 293114475 kg, with the Department of $148816708.
