Calcium silicate insulation board

     Calcium silicate insulation board may also be referred to as: calcium silicate board, calcium silicate insulation panels, asbestos-free calcium silicate board, asbestos-free calcium silicon insulation board, insulation with calcium silicate boards, porous calcium silicate, it is a Species by the siliceous material (main ingredient is SiO2, such as quartz powder, fly ash, diatomaceous earth, etc.), calcareous materials (main ingredient is CaO, such as lime, calcium carbide sludge, cement, etc.), reinforcing fibers, additives and other by a certain percentage with a new type of inorganic materials by scooping or molding, autoclave curing and other processes made of, it is a white, new insulation material rigid. With a light weight, high strength, low thermal conductivity, high temperature, corrosion resistance, can be cut, to saw and so on. Calcium silicate boards have good thermal insulation properties, 10mm thick wall insulation properties better than ordinary brick wall effect, but also has good sound insulation. Stable calcium silicate board, acid, corrosion is not easy, nor be subject to moisture or pests and other damage, it can ensure a long service life. Is widely used in electricity, metallurgy, petrochemical, construction, shipbuilding and other areas of equipment, piping, wall and roof insulation and fire insulation. Is currently the most power, petrochemical, metallurgy and other sectors welcome new rigid insulation material. The calcium silicate insulation board is particularly suitable for all kinds of heat treatment industrial furnaces for heat insulation, can replace diatomite, perlite materials, fire-resistant fiber, strong insulation properties.

Depending on the temperature of different calcium silicate divided into two categories: general type and high temperature type:

     Ordinary calcium silicate according to the density divided into three types: 240, 220, 170, 650 ℃ are available for the following selection of equipment and pipe insulation. Hydrophobic type calcium silicate as an ordinary performance improved, it added water component in the production process, in addition to the performance of ordinary calcium silicate, but also with non-absorbent, moisture-proof characteristics, particularly suitable for marsh ground overhead pipes buried underground pipes, the trench and wet areas.

     Belong to non-asbestos calcium silicate insulation board lightweight calcium silicate insulation board. When used with lightweight refractory bricks or refractory concrete use, it is ideal for backing insulation. As we all know, low thermal shock resistance of calcium silicate that it can not be used in the hot end of the liner.

     Calcium silicate insulation board has low thermal conductivity, high heat resistance, low shrinkage, low bulk density, sulfur-free and low iron content and other advantages.

 

Calcium silicate insulation board features

1, the safe use of warm clothes up to 65O ℃, higher than 30O ℃ ultra-fine glass wool products, expanded perlite products higher than 150 ℃.

2, low thermal conductivity (γ≤0.56w / mk) far less than other rigid insulation materials, and composite silicate insulation materials.

3, bulk density of small, rigid insulation materials in the lowest weight, the insulation layer can be thin, can be a significant reduction in construction just stand, install low labor intensity.

4, the thermal insulation products will not burn odorless, non-toxic, high mechanical strength.

5, the construction safe and convenient.

6, the article can be long-term repeated use, the use of cycle can be decades, is still lower technical indicators.

7, the appearance of white, smooth and beautiful, bending, compressive strength is good, low loss in transportation, using the process.
