What are the types of cement boards?

 

Fiber Cement Board Adhesive.jpgThere are many types of cement boards, which are mainly divided into ordinary cement board, fiber cement board and fiber cement pressure board according to grades; they are mainly divided into non-pressure board (plain board), fiber reinforced cement board and high density fiber cement pressure board according to strength; Mainly divided into chrysotile fiber cement board and non-asbestos fiber cement board.


Ordinary cement board is the lowest-grade product commonly used. The specification is mainly 1200*2400*, the thickness is between 6-12mm, the market price is about 10 yuan and 20 yuan. The main components are cement, fly ash, Sand, the cheaper the price, the lower the amount of cement used, some manufacturers do not even use cement in order to reduce costs.


Fiber cement board, also known as fiber reinforced cement board, is mainly distinguished from ordinary cement board by adding various fibers as reinforcing materials, which greatly improves the strength, flexibility, folding resistance and impact resistance of the cement board. The added fibers mainly include mineral fibers such as asbestos, plant fibers such as pulp, synthetic fibers such as vinylon, and rayon fibers such as glass wool. According to the different fibers, it is divided into chrysotile and non-asbestos.


The main difference of fiber cement pressure plate is that it is pressed by special press in the production process, with higher density, higher waterproof, fireproof and soundproof performance, stronger load bearing, anti-folding and impact resistance, and its performance. In addition to raw materials, formulations and processes, it depends mainly on the pressure of the press.
