cement As the name suggests, the board is a kind of building used for processing and producing cement as the main raw material Flat 。 It is between plasterboard and Stone It is a kind of construction product that can drill holes, cut freely and carve. It is obviously superior to gypsum board and board In terms of price, it is lower than stone, so it is now widely used in the construction industry.
There are many kinds of cement boards.
If classified by grade, it can be divided into ordinary board, fiberboard and fiber pressure board;
If classified according to the fiber used, it can be divided into chrysotile asbestos board and non asbestos board;
If divided by strength, it can be divided into non pressing plate (ordinary board), fiber reinforced board and high-density fiberboard.
The ordinary board is widely used in the market, and it is a low-grade product. The main ingredients are cement, fly ash and sand. The cheaper the cement board is, the lower the cement content is. Even some manufacturers simply do not add cement to reduce costs.
The difference between fiberboard and ordinary board is that fiber of various materials is added to fiberboard as the reinforcement of cement board, which greatly improves the strength, flexibility, bending resistance and impact resistance. Generally, there are many kinds of fibers that can be added, such as mineral fibers such as asbestos, plant fibers such as pulp, synthetic fibers such as vinylon, and man-made fibers such as glass fiber.
According to the difference of fiber added, the fiberboard is divided into chrysotile asbestos board and non asbestos board.
