1.5g / cm3 high density 1.5-2.0g / cm3. Low density is generally used for low-rise building ceiling partitions and other parts, medium density is generally used Mid-range building wall ceiling, high density generally used for high-grade building steel structure, steel floor, etc. At present, China's cement fiber board according to the national construction industry standards are divided into two categories. Defects
of high-density fiber cement board easy deformation, deformation coefficient of low-density products to be smaller. 3, according to the pressure to have no pressure plate and pressure plate points. Medium and low density cement fiber boards are no pressure plate, high-density pressure plate. Pressure plate, also known as fiber cement pressure plate, requires a special press production, no press can not do
business. According to the level of density, fiber cement pressure board is divided into: 1) ordinary board, density 1.5-1.75g ??/ cm3; 2) excellent board, density 1.75-1.95g / cm3; 3) Premium board, density 1.95g / cm3 above . 4, according to the thickness (1) thin plate, 2.5-3.5mm; (2) conventional plate, 4-12mm; (3) thick plate, 13-30mm; (4) super thick plate, 31-100mm.
