What is the kind of plate?
Good fire performance: As the amalgam cement board itself is not combustible, and the fire burning process will absorb a lot of heat, delay the ambient temperature rise, therefore, the United States rock cement board has a good fire retardant performance. Inspection and testing by the National Fire Equipment Supervision and Testing Center, the United States rock cement board wall fire resistance up to 8 hours. To achieve a level of fire, the gypsum board can only reach the fire three. Meishan cement board fire aging by CNS12514 wet two-hour fire aging test.
Thermal insulation: As the use of Portland cement board plant fiber plant structure, the thermal conductivity of 0.176W / (M.K), and gypsum board is almost the same, and gray sand brick block (1.1W (M .K) compared to its thermal insulation has a significant advantage.
Light weight: the use of the United States rock cement board for the wall, the weight of only the same thickness of the brick wall 1/15, block the wall of the 1/10, is conducive to structural seismic, and can effectively reduce the basic and structural cost.
