summary

Calcium silicate board is a new type of inorganic building material, which is made of siliceous material (main component is SiO2, such as quartz powder, fly ash, diatomite, etc.), calcareous material (main component is Cao, such as lime, calcium carbide mud, cement, etc.), reinforcing fiber, auxiliary agent, etc. according to a certain proportion, it is made of a new type of inorganic building material by copying, molding, autoclaving and curing. Because of its high strength, light weight, good machinability and non flammability, it is widely used in ship's cabin board, suspended ceiling, non load bearing wall of building, and other places with fire protection requirements. Calcium silicate board is divided into thermal insulation calcium silicate board and decoration calcium silicate board.

(1) Calcium silicate board for thermal insulation

Calcium silicate board for thermal insulation is called microporous calcium silicate. It is a new kind of white and hard thermal insulation material. It has the characteristics of light bulk weight, high strength, small thermal conductivity, high temperature resistance, corrosion resistance, cutting and sawing. It is widely used in electric power, metallurgy, petrochemical, construction, ship and other fields of equipment, pipe, wall and roof insulation and fire and sound insulation. The thickness is usually more than 30mm and the density is 200-1000kg / m3.

(2) Calcium silicate board for decoration

Calcium silicate board for decoration, invented by ocfg company of the United States, is a new type of building board famous for its comprehensive performance. It has been widely used and developed in developed countries since 1970s. Europe, America, Japan, Australia and Taiwan are the countries and regions where calcium silicate board is most commonly used. It was successfully developed in China in the early 1980s, entered the development stage in the mid-1980s, and was widely applied in the late 1990s. The thickness is 4-20 mm, and the length and width are mainly 1220 * 2440 mm. At the same time, the decorative calcium silicate ceiling made of large-scale calcium silicate board is widely used for ceiling due to its advantages of fire-proof and anti subsidence varieties.

Scope of application

Places of use: commercial buildings: business buildings, entertainment places, shopping malls, hotels, industrial buildings: factories, warehouses, residential buildings: new residences, renovated public places: hospitals, theatres, stations It is mainly used in the fields of wall, ceiling, floor, furniture, road sound insulation, sound absorption barrier, ship compartment and air duct, as well as sound-absorbing wall, sound-absorbing ceiling, pouring wall, composite wall panel and other fields.
