The development and variety of building insulation materials recently, the relevant experts to re define the green material, the use of raw materials, product manufacturing, use or recycling and waste disposal and other aspects of the earth's environment load for the smallest and beneficial to human health materials, also known as the environment coordination materials". In the construction and industrial use of good thermal insulation technology and materials, often can play a multiplier effect. Statistics show that the construction of the use of a ton of mineral wool insulation products, a year can save a ton of oil. Beijing court in North District was such that, the coal saving rate per unit area per year for 11.91 kilograms of standard coal / m2. Industrial equipment and pipe insulation, using good insulation measures and materials, can significantly reduce the energy consumption and production costs, improve the environment, and have better economic benefits. Such as: industrial equipment and pipeline engineering, good thermal insulation conditions, can make the heat loss reduction of about 95%, usually used in thermal insulation material of investment about a year or so can be recovered by saving energy. Before 1980, China insulation materials, the development is very slow, the number of insulation material factory can produce a small amount of expanded perlite, expanded vermiculite, slag cotton, superfine glass cotton and microporous calcium silicate and other products, mineral wool factory rarely, production capacity of less than ten thousand tons, scattered cotton, calcium silicate insulation material is only three, with an annual output of 8000 cubic meters. Product quantity, quality can not meet the requirements. The main energy saving and heat preservation material is as follows: mineral wool and mineral wool is a kind of high quality heat preservation material, has the history of 100 years of production and application. In 1840 the British first discovered that the melting of slag forming fiber, and production of slag cotton; 1880 Germany and the United Kingdom began producing slag cotton, later other countries have used and production, this century, the development of the world's most rapidly; 1980 years, the world's mineral wool production is relatively stable, the main reason is other thermal insulation materials such as glass cotton, foam development, coupled with the development of the developed countries, the annual output of 8000000 tons, mineral cotton in the construction of the most widely used, for example, the United Kingdom accounted for 70%, accounting for 92%, 90% of the United States. Our country in the early 80's the introduction of Sweden 16300 tons of production line, our country's thermal insulation material to scale, performance is more excellent, the variety specification is more complete the direction of a big step. Subsequently, Harbin, Taiyuan, Hohhot, Qigihar, Urumqi, Dongguan, Yinchuan, Xining, Shanghai, Beijing, from Sweden, Japan, Australia, Italy, Britain, Poland, China and Nanjing to build a production line. Production capacity of 3000 tons / year, there are 80, production enterprises have 180 or so, the design capacity of 550000 tons. Rock wool production technology: small factory production rock wool uniform degree of difference; automatic adjustment of imported equipment cloth cotton velocity and thickness, cotton, fast speed of the driving gear, a proportional relationship. Therefore, manufacturers of rock wool density uniform, slag ball content. Glass wool and rock wool products following, a bulk density appeared light, insulation insulation material. Japan's 90 annual output of 205000 tons, the United States in 1985 production of 1925000 tons, 115000 tons of French production in 1984. Before the 1980s, our country only a few extra fine glass wool small factory, single variety, poor quality, mid 80s, Shanghai, Beijing introduction Nitto spinning technology and equipment, the centrifugal blowing process, products are: board, carpet, shell, such as decorative ceiling. Characteristics: light weight, generally 10 - 96kg / m3, 20kg / m3 below is felt, 24 - 48kg / m3 for cardboard, 48 - 96kg / m3 for cardboard, the 48kg / m3 to do the ceiling, the softening point is about 500 DEG C, holding 300 DEG C, American consumption larger, k = 0.9. Calcium silicate insulation products in the domestic 70 years of successful development, with high compressive strength, small thermal conductivity, easy construction, can be used repeatedly, in the power system is widely used. By the end of 1994, the country has nearly 50 production enterprises, the total design and production capacity of nearly 300000 square meters, the current can maintain normal production of more than 30, the annual output of about 150000 square meters, its application is under the impact of mineral wool, coupled with high prices, poor publicity, sales in recent years, so that production is restricted. Application: high temperature resistance, the price is relatively low, the biggest flaw is that the heat expansion of its own easy to crack, weld the wrong move; leave a space, hot air out, cold air in, although outside the surface temperature is not high, but the heat loss. Aluminum silicate fiber is also called refractory fiber, mainly used as the furnace insulation material, in 1971 the development of China's success, the current production enterprises 200 or so, the total production capacity of more than 40000 tons / year, the annual output of nearly 20000 tons. More varieties, the major domestic ordinary aluminium silicate fiber, high pure aluminium silicate fiber, high aluminum and aluminum fiber and a small amount of products, are the medium and low-grade products; polycrystalline Mo mullite fiber, polycrystalline alumina fibers and polycrystalline zirconia fiber high-grade products. The most common for small workshop style production, one after another from the United States introduced four production lines, advanced technology, instant speed jilt into fiber, dry needle felt, stable quality, can withstand temperature of 800 - 1250 C. Characteristics: the acidity of more than 2, high temperature, general chemical pipeline 1000 degrees C, must use this material. Solution temperature at 2000 C. Foamed plastics is made of synthetic resin, with many small holes of plastic products, it has a low thermal conductivity, processing, and other advantages, in the construction of the first use. Mainly used for the packaging industry (such as refrigerators), buried pipeline insulation, cold insulation. The main products are polystyrene foam and polyurethane foam, but there are problems in the application of the construction field. In recent years, it has been used in the steel wire mesh sandwich panel, color steel plate composite sandwich plate, although it has certain limitation.
