Introduction to cement fiberboard
1. What is calcium silicate board?
People call the light board made of lime and quartz powder as the main body, fiber as the reinforcing material, mixed with water to make the slab, and then cured by autoclave as calcium silicate board
2. Source of calcium silicate board? Calcium silicate board, invented by ocfg company of the United States, is a new type of building board famous for its comprehensive performance. It has been popularized and developed from developed countries since 1970s, and soon became popular all over the world
3. History of calcium silicate board in China? China's calcium silicate board industry started in the late 1990s In recent years, China's calcium silicate board industry has made rapid development, and the annual output growth rate is more than 30% According to incomplete statistics, the annual output of calcium silicate board reached about 200 million square meters in 2008 Among them, 30% of the products are exported
4. Type of calcium silicate board? At present, there are two kinds of calcium silicate board in China, one is calcium silicate board for thermal insulation, and the other is calcium silicate board for decoration Calcium silicate board for thermal insulation, also known as microporous calcium silicate board, is a white and hard new thermal insulation material. It has the characteristics of light bulk weight, high strength, low thermal conductivity, high temperature resistance, corrosion resistance, cutting and sawing. It is widely used in the thermal insulation, fire prevention and sound insulation of equipment pipes, walls and roofs in the fields of electric power, metallurgy, petrochemical, architecture, ships, aerospace, submarines and so on Its thickness is usually more than 20mm and its density is 110-140kg / m3 The maximum working temperature can reach 1000 ℃ Calcium silicate board for decoration, also known as fiber cement board, is a light board with energy-saving, environmental protection, safety, multi-function and other properties.
5. Production process of calcium silicate board? Calcium silicate board is a new type of lightweight board made by mixing siliceous materials and calcareous materials in a certain proportion, taking organic synthetic fiber, inorganic mineral fiber or cellulose as reinforcement, and through pulping, molding, autoclave curing, drying, sanding and other processes.
6. What are the main functions of calcium silicate board? As a new type of environmental protection building material, calcium silicate board not only has the functions of traditional gypsum board and mineral wool board, but also has the advantages of superior fire resistance, moisture resistance and long service life. It can be widely used in industrial and commercial engineering, ceiling and partition wall of building, home decoration, lining board of furniture, lining board of billboard, partition board of ship, shed board of warehouse, wall board of floor and tunnel and ventilation flue of subway.
7. Application scope of calcium silicate board? Light and convenient calcium silicate board can be used in business buildings, entertainment places, shopping malls, hotels, factories, warehouses and new houses, renovated public places, hospitals, theatres, stations, etc. It is mainly used for industrial panels such as wall, ceiling, floor, furniture, road sound insulation, sound-absorbing barrier, ship compartment and air duct, as well as panels of sound-absorbing wall, sound-absorbing ceiling, cast-in-place wall and composite wall panels.
