Is the cement fiber outer wall plate affected by the blisters?
In particular, the water absorption of the sheet is very important, especially asbestos-free, the density is inversely proportional to the water absorption, the higher the water absorption, the lower the density, the resistance to freezing and thawing and stability The worse, the easier it is to stratify,
High density board for external walls. Calcium silicate board is autoclaved, the pressure plate is autoclaved and not autoclaved, autoclaved weather resistance is better, the same pressure, the density of calcium silicate board lower, because the formula has a lighter lime, There is no cement pressure plate.
