Through special fiber cement board-bit, 100% asbestos products, sheet during use does not produce any toxic gases and radiation. As flame-retardant materials, when the fire broke out, not just the fire department, the fire spread place will be damaged, bringing damages, so the outer wall of flame resistance is extremely important. Through special fiber cement board having excellent flame resistance, and the fire will not result in cracking, loss and mold growth conditions no cracking, no mildew in any environment, at 11 atmospheric pressure curing hardening, its structural decided pests can not survive in the plate and the keel plate consisting of a strong, ceiling or other components, the use of fiber cement board has a light weight and high strength bearing the superiority of the dry plate construction jobs, construction fast; woodworking tools generally available , ease of processing sheet metal, sheet metal surface can handle a variety of finishes, such as paint or glue plywood through a variety of special fiber cement board by high temperature autoclave procure cement calcium silicon and quartz powder in a chemical reaction to form The new crystalline material "Tuobei Mo to stone" within 24 hours after the molding process of the curing reaction, so that the sheet shape stability, the characteristics of deformation coefficient.
