Energy is an important material basis for human survival and development, _Since the 21st century, energy saving and emission reduction has become the common goal of the development of countries around the world, thermal insulation materials have been a large number of development and application. 1050 degree high temperature resistant calcium silicate board has low thermal conductivity, light weight, high strength, high temperature resistance and other excellent properties, become one of the most promising thermal insulation materials. Calcium silicate board is mainly made of silicon powder, calcium powder, natural wood pulp after high temperature and high pressure steam curing made of low, medium and high density new environmental protection insulation material.

Calcium silicate board has good fire resistance, high temperature resistance, waterproof, light weight, easy to cut and other properties. Applicable to steel, petrochemical, ceramics, glass, cement, external wall insulation and all kinds of furnace insulation, and electric power, machinery, electronics, shipbuilding and other industries of thermal insulation. Calcium silicate is a common alternative to asbestos as a safe insulation material. Calcium silicate is one of the most widely used materials for fire prevention in Europe. Europeans are more inclined to use calcium silicate as cladding. In smelting metal ores, silica reacts with calcium carbonate to form this substance to form slag.
