What are the classifications of calcium silicate board?

Calcium silicate board, as its name implies, is a plate-like building material made of calcium silicate, which belongs to a new type of building board. Not only has high environmental protection, but also has excellent fire prevention, moisture prevention, sound insulation and heat insulation effects. Calcium silicate board is generally divided into two types, one is for thermal insulation and the other is for decoration. Let's first understand the classification and performance characteristics of calcium silicate board. Brief introduction of calcium silicate board

Calcium silicate board is made of loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials and silicon-calcium materials as main cementing materials. After pulping, molding and accelerating curing reaction in saturated steam at high temperature and high pressure, calcium silicate gel is formed. It is a new type of building and industrial plate with excellent performance. Its products are fireproof, moisture-proof, sound-proof, moth-proof and durable. It is an ideal decorative board for ceilings and partitions.

Second, the classification of calcium silicate board

1, calcium silicate insulation board

Calcium silicate board for thermal insulation, called microporous calcium silicate, is a new type of white hard thermal insulation material, which has the characteristics of light bulk density, high strength, low thermal conductivity, high temperature resistance, corrosion resistance, cutting and sawing. Widely used in electric power, metallurgy, petrochemical, construction, shipbuilding and other fields of equipment, pipelines, walls and roofs for thermal insulation and fire and sound insulation. Generally, the thickness is above 30mm, and the density is 200- 1000kg/m3.

2. Decorative calcium silicate board

The decorative calcium silicate board invented by American OCFG Company is a new building board with excellent comprehensive performance, which has been popularized and developed in developed countries since 1970s. Europe, America, Japan, Australia and Taiwan Province Province are the most common countries and regions that use calcium silicate board. China successfully developed calcium silicate board in the early 1980s, entered the development stage in the mid-1980s, and was widely used in the late 1990s. The thickness is 4-20mm, and the length and width are mainly 1220*2440mm. At the same time, there are decorative calcium silicate ceilings made of large calcium silicate boards, which are widely used in ceilings because of their many advantages such as fire resistance and settlement resistance.

Third, the performance characteristics of calcium silicate board

1, fire performance

Calcium silicate board is an incombustible A 1 grade material. In case of fire, the board will not burn or produce toxic smoke.

2, waterproof performance

Calcium silicate board has good waterproof performance, and can still maintain stable performance in high humidity places such as toilets and bathrooms without expansion and deformation.

3, high strength

The strength of calcium silicate board is high, and the strength of 6mm thick board is much higher than that of 9.5mm thick ordinary gypsum board. The calcium silicate board wall is solid and reliable, and it is not easy to be damaged or broken.

4, the size is stable

The calcium silicate board adopts advanced formula, and the production is controlled under strict quality, so that the wet expansion and dry shrinkage of the board are controlled in the most ideal range.

5. Thermal insulation and sound insulation

Calcium silicate board has good thermal insulation performance, and the thermal insulation performance of 10mm thick partition wall is obviously better than that of ordinary brick wall, and it also has good sound insulation effect.

6, long service life

Calcium silicate board has stable performance, acid and alkali resistance, is not easy to corrode, will not be damaged by moisture or insects and ants, and can ensure a long service life.
