Calcium silicate board can be used on the external walls, waterproof crack?

Answer:

Calcium silicate board has excellent water resistance, in the bathroom, bathroom and other places of high humidity, can still maintain the performance of stability, will not swell or deformation.

Calcium silicate board is less to do outside the wall panels, are generally decorated with interior walls The main reason is its advantages: light, moisture-proof performance is good, easy to change color, high hardness, good sound insulation performance. The calcium silicate board also has obvious shortcomings: the installation is not easy to replace, the installation of the use of iron keel, the price is more expensive and easy to break, slit. But now there are external walls with calcium silicate board, but from the cost point of view, the proposed external walls or do not use calcium silicate board

Calcium silicate board as a new green building materials, in addition to the function of the traditional gypsum board, but also has excellent fire performance and moisture resistance, the advantages of long life, a large number of industrial and commercial applications in the ceiling ceiling and partition, home decoration, Furniture liner, billboard liner, ship compartment board, warehouse floor, network floor and tunnel and other indoor works of the wall. Calcium silicate board is made of inorganic mineral fiber or cellulose fiber and other loose short fiber as a reinforcing material, with siliceous-calcium material as the main cementing material, pulping and molding, accelerating the curing reaction in high temperature and high pressure saturated steam to form Calcium silicate gel made of the plate. Is a good performance of the new building and industrial sheet, its products fire, moisture, noise, insect moth, durability is better, is the ceiling, cut off the ideal decorative plate.
