Fiber Cement Board/ Calcium Silicate Board

Variety and characteristic
Fiber cement board/Fiber reinforced calcium silicate board (so FC board) has many advantages: High strength with light weight, fire resistant and heat insulated, easy to process and so on. It can be used in many areas such as: Fire isolation wall board, roof decoration board, air channel for public high buildings, as well as partition board and anti-fire door for various kinds of vessels.


Technology
FC board use inorganic mineral fiber or cellulosic fiber as reinforcement agent siliceous material and calcareous material as main cementitious material. Process stages include: Slurry preparation, board forming, stacking, pre-curing, module stripping, autoclaving and curing. To increase board quality, drying stage as well as sanding, edging and painting stages can be added, which also increased additional value of board. Process technique contains molding **- pressing process, flow-on process and hatcheck process.

Main raw material
Reinforced fiber (pulp, wollastonite, glass fiber, mica. Chrysotile and so on), Siliceous material (quartz powder, fly ash, diatomite and so on. ), calcareous material (unslaked lime powder, cement) and additives.
