Calcium silicate board is one new type of waterproof and fireproof board. It has lots of advantages such as sound insulation, fireproof, waterproof,
mouldproof, heat insulation, light, good strength etc.
The main raw materials are quartz powder(pulp), cement, hydrated lime powder, paper pulp, wollastonite and other accessories( mica, glass fiber, etc.)
The production process of calcium silicate board:
1. Quartz plasma processing
2. Paper processing
4. Seperation, mixing and slurry control
5. Molding, answer the billet and stacking
6. Maintenance and stripping
7. Autoclaved maintenance
9. Sanding, edging and chamfering
Standard calcium silicate board dimension:
It adopts slurry flowing method or hatschek method.We will provide one-stop service.

Calcium silicate/ fiber cement board use inorganic mineral fiber or cellulosic fiber as reinforcement agent and 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 are 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.
Standard of production:
Calcium silicate board production based on Industry Standard JC/T564-2008—“Fiber reinforced calcium silicate board”.
