Asbestos is a natural fibrous mineral silicate minerals in general, can be divided into serpentine asbestos mine (mine chrysotile) and amphibole asbestos mine two categories. Chrysotile mines can be a splitting of excellent, good spinnability and greater tensile strength, and with insulation, insulation, and acid and alkali resistance, mainly for the production of textiles, brake, rubber, cement, insulation and other asbestos products, asphalt products and asbestos and asbestos products such as reinforced plastics, machinery, transportation, chemical industry, metallurgy, construction, electricity and other industries are also widely used in defense and aerospace industries also have many uses.
60 years since the pollution of the environment as people of asbestos-induced cancer gradually deepen the understanding, development and application of gradual development of asbestos substitutes, particularly to the 80's, but so far the development of asbestos substitutes, such as glass fiber, metal fiber, petrochemical fiber, carbon fiber, mica and mineral wool, etc., there is no asbestos in a position to replace, particularly asbestos cement and friction materials have poor quality, low cost and large-scale advantages, it is unmatched by the substitute The.
World reserves of about 500 million tons of asbestos out, mainly in the former Soviet Union, Canada and South Africa. Asbestos mine in China nearly 100 million tons of proven reserves, is the country with extensive resources of asbestos.
