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.
