In 1, according to fiber: most of the current domestic use are asbestos fiber enhanced the fiber cement board is called asbestos fiber cement flat; another is non asbestos fiber, pulp, wood, glass fiber instead of asbestos fiber reinforcement are referred to as non asbestos fiber cement flat.
2, according to the density of points: low density 0.9-1.2g/cm3, high density 1.5-2.0g/cm3. 1.2-1.5g/cm3 density in low density and low ceiling of the building wall is generally used in other parts, generally used for mid-range density building walls ceiling, highly dense generally used for steel structure wall of high-grade buildings, steel structure floor; China fiber cement board according to the national construction industry the standard is divided into two categories. The defects of high density fiber cement plate are easy to be deformed, and the deformation coefficient of medium and low density products is smaller.
3, according to the pressure: there are no pressure plate and pressure plate. The medium and low density fiber cement plates are all pressure free plates, and the high density is the pressure plate. The pressure plate is also called the fiber cement pressure plate, which needs special press production, and the enterprise without the press can not do it. According to the density, fiber cement pressure plate is divided into: (1) ordinary board, density 1.5-1.75g/cm3; (2) superior board, density 1.75-1.95g/cm3; (3) super superior plate, density 1.95g/cm3 above.
4, according to the thickness: (1) ultra thin plate, 2.5-3.5mm; (2) conventional board, 4-12mm; (3) thick plate, 13-30mm; (4) super thick plate, 31-100mm. The ordinary manufacturers can not do super thin plate and super thick plate, which is also an important basis for the industry to measure the production capacity and technical level of the enterprise.
