Calcium silicate board the greater the density of the better performance?
Used to make the external walls must be slightly higher density, so that the plate density is good, low water absorption, not easy to deformation cracking. Han De Bang and the dragon, love Fu Xi is a good domestic manufacturers to do a few manufacturers.
Now the majority of the market are coated with the physical pressure, and some autoclave autoclaved through the cement pressure plate.
Of course not, any material of the plate is not the greater the density the better. Calcium silicate board currently on the market generally used in the production of the slurry process, the large plate is not pressurized density of about 1.2, used to do the interior can be used if the external must use the physical pressure of the calcium carbonate plate or High temperature autoclaved curing cement pressure plate.
