With the popularization of new building materials, fiberboard is used more and more widely, and it can be used in different building parts such as suspended ceilings, partition walls, roofs, and exterior walls. There are many different categories for the same product. So what are the classifications for fiberboard? The following is an analysis by the Fiberboard equipment manufacturer:

 

       Divided by fiber: In the past, most of the industry used asbestos fiber for reinforcement. This kind of cement board is called chrysotile cement slab, but now the country has stipulated that cement board containing asbestos cannot be produced; the other is not Those that contain asbestos fibers, and those that use paper pulp, wood chips, and glass fibers to replace asbestos fibers for reinforcement are collectively referred to as non-asbestos cement slabs.

 

       Divided by density: low density 0.9-1.2g/cm3, medium density 1.2-1.5g/cm3 high density 1.5-2.0g/cm3. Low density is generally used for low-end building ceiling partitions and other parts, medium density is generally used for mid-range The ceiling of the building partition wall is highly dense and is generally used for the steel structure exterior wall of the building, steel structure floor slab, etc.; the current cement board is divided into two categories according to the construction industry standards. The shortcomings of high-density cement board are easy to deform, and the deformation coefficient of medium and low-density products should be smaller.

 

　　According to the pressure: whether there is a pressure plate and a pressure plate. Low- and medium-density cement boards are non-pressure boards, and high-density cement boards are pressure boards. Pressure plates are also called cement pressure plates, which require special press production, which cannot be done by companies without presses. According to the density, cement pressure boards are divided into: 1) ordinary boards with a density of 1.5-1.75g/cm3; 2) superior boards with a density of 1.75-1.95g/cm3; 3) special boards with a density of 1.95g/cm3 or more.

 

       Divided by thickness: 1) Thin plates, 2.5-3.5mm; 2) Conventional plates, 4-12mm; 3) Thick plates, 13-30mm; 4) Extra-thick plates, 31-100mm. General manufacturers can’t make thin plates and thick plates. Board, which is also an important basis for measuring the production capacity and technical level of enterprises in the industry.
