Calcium silicate board is a new type of green and environmentally friendly board made of loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcement materials, with silicon calcium materials as the main bonding raw material. It is formed by pulping and solidified by high-temperature and high-pressure saturated steam acceleration reaction to produce calcium silicate cementitious system. It has dual properties of building decoration and industrial application. In terms of core product features, calcium silicate board not only inherits the basic functions of traditional gypsum board, but also has superior fire resistance, flame retardancy, moisture resistance, waterproofing, sound insulation and absorption, insect and moth resistance, and structural durability. Its service life is much longer than traditional similar building materials, and as an inorganic building material, the release of harmful substances such as formaldehyde is low, which meets the environmental protection requirements of green building materials. The typical technical parameters in the industry are: according to density, it can be divided into low-density type (<1.2 g/cm ³), medium density type (1.2-1.5 g/cm ³) and high-density type (>1.5 g/cm ³). The mainstream product fire rating can reach A1 level non combustible standard. The moisture content of conventional products is ≤ 10%, and the thermal conductivity coefficient is 0.15-0.30 W/(m · K). The general specification size is 2440mm × 1220 mm, and the thickness coverage is 4 mm~25 mm, which can meet the customized needs of different scenarios. At present, calcium silicate board has been widely used in various fields such as suspended ceilings, partition walls in industrial and commercial engineering buildings, indoor wall panels and furniture lining panels in home decoration, as well as advertising board lining panels, warehouse shed panels, industrial network flooring, tunnel and other underground engineering wall panels. With outstanding environmental attributes and comprehensive performance advantages, calcium silicate board has become the mainstream product in the current field of building decoration to replace traditional organic boards and low performance inorganic boards, and is an ideal green decorative board for the new generation.
Fire resistance performance
Calcium silicate board is a non combustible A1 grade material. In the event of a fire, the board will not burn and will not produce toxic smoke.
waterproof performance
Calcium silicate board has good waterproof performance and can maintain stable performance in high humidity places such as bathrooms and toilets, without expansion or deformation.
high strength
Calcium silicate board has high strength, and the strength of 6mm thick board greatly exceeds that of 9.5mm thick ordinary paper faced gypsum board. Calcium silicate board walls are solid and reliable, not easily damaged or broken.
dimensional stability
Calcium silicate board adopts advanced formula and is produced under strict quality control. The wet swelling and dry shrinkage rate of the board are controlled within the most ideal range.
heat insulation and sound insulation
Calcium silicate board has good thermal insulation performance, and the thermal insulation performance of 10mm thick partition wall is significantly better than that of ordinary brick wall, while also having good sound insulation effect.
Long service life
Calcium silicate board has stable performance, acid and alkali resistance, is not easily corroded, and will not be damaged by moisture or insects, ensuring a long service life.
Calcium silicate board is a new type of inorganic building material made by mixing siliceous materials (mainly composed of SiO2, such as quartz powder, fly ash, diatomaceous earth, etc.), calcareous materials (mainly composed of CaO, such as lime, calcium carbide mud, cement, etc.), reinforced fiber materials, additives, etc. in a certain proportion, and through processes such as copying, molding, and steam curing. Due to its high strength, light weight, good processability, and non flammability, it is widely used in ship compartments, ceilings, non load bearing walls of buildings, and other places with fire protection requirements. Calcium silicate board is divided into insulation calcium silicate board and decoration calcium silicate board.
Calcium silicate board for insulation
Calcium silicate board for insulation is called microporous calcium silicate, which is a new type of white and hard insulation material. It has the characteristics of light bulk density, high strength, low thermal conductivity, high temperature resistance, corrosion resistance, cutting ability, sawing ability, etc. Widely used in the fields of power, metallurgy, petrochemicals, construction, ships, etc. for insulation and fire insulation of equipment pipelines, walls and roofs. The thickness is usually above 30 mm and the density is between 200-1000 kg/m3.
Calcium silicate board for decoration
Calcium silicate board for decoration, invented by OCFG company in the United States, is a new type of building board known for its comprehensive performance. It has been widely used and developed in developed countries since the 1970s. Europe, America, Japan, Australia and Taiwan, China are the countries and regions where calcium silicate boards are most commonly used. China successfully developed calcium silicate boards in the early 1980s, entered the development stage in the mid-1980s, and were widely promoted and applied in the late 1990s. The thickness is between 4-20mm, with a main length and width of 1220 * 2440mm. At the same time, there are decorative calcium silicate ceilings made of large-sized calcium silicate boards, which are widely used for ceilings due to their advantages of fire resistance, anti sinking, and variety.
