Specification, movement and cutting of fibre reinforced cement board
Fiber cement board abbreviated as FC board
Fiber reinforced cement board, also known as fiber reinforced cement board, is a construction cement plate made of fibers and cement as the main raw materials. It is widely used in various fields of construction industry with its superior performance. According to the different adding fibers, it can be divided into chrysotile fibre cement board and asbestos-free fibre cement board. According to the different forming pressure, it can be divided into fibre cement pressure board and fibre cement pressure board.
General specification: length: 3000mm-2440mm
Common thickness: 4-12 mm
The thickness can be extended to 2.5mm-90mm in China. The sizes of domestic boards are generally 1200 x 2400 or 1220 x 2440. The former is the domestic general standard and the latter is the international general standard. (Other smaller sizes can be cut at will)
According to density, it can be divided into three categories: high, medium and low. The edge of low density plate is rough after cutting, and that of high density plate is neat after cutting.
Different specifications of fiber reinforced cement board have different heat and sound insulation performance. Generally speaking, the higher the density and thickness of the board, the better the heat and sound insulation performance. In addition, its insulation performance is worth recommending.
Plate movement and cutting
The fiberboard itself is heavier, so it needs at least two people to move the whole uncut board. The thickness of 4mm-6mm belongs to the thinner plate. The thin plate is fragile relative to the thick plate. It needs to be moved carefully before installation. If it is not protected carefully, it is fragile and damaged easily.
Installation of fiberboard requires at least two people, one person to stabilize the position of the board, and one person to fix it with special nails.
Cutting fibre reinforced cement boards usually requires an electric saw or a mechanical tool. There are three ways to cut fibre reinforced cement boards:
1. Sheet can be broken by heavy cutting tools.
2. Use Fiber Cutting Machine (Australian Cutting Method)
3. Heavy or high-density plates require electric sawing
In the cutting process, we must pay attention to the wind direction, try to avoid powder inhalation in the body, wear masks or special protective tools, plate powder into the lungs for a long time may lead to disease.
After installation, various coatings can be applied for finishing (waterproof coatings are needed where exposed to air). Fixed joints need to be filled with wood blocks, and the whole surface of the board needs to be painted, so as to prolong the service life of the board. Installation of fixed and painted fiberboard, its maintenance workload is very small. Thick and high-density plates have good impact resistance, but thin and low-density plates need to be protected from external impact. Compared with wood wallboard, fiber cement board has good waterproof, fire-proof and sound-proof effect, and it does not produce termites, is not easy to rot, and has better corrosion resistance.
