Panel is the protective layer of the insulation layer, but also the bearing body. Different materials of the panel, determines the insulation decorative one of the applicable areas of the board. Factory selection of high quality inorganic resin plate, can be divided into calcium silicate board and fiber cement board. Calcium silicate board is a kind of siliceous material (main component is SiO2, such as quartz powder, fly ash, diatomaceous earth, etc.), calcium material (the main ingredient is CaO, such as lime, calcium carbide, cement, etc.) Reinforced fiber materials, additives, etc. by a certain proportion with the copy or molding, autoclave curing and other processes made of a new type of inorganic building materials, and fiber cement board refers to the cement as the basic materials and adhesives, To mineral fiber cement and other fibers as a reinforcing material, by the pulp, forming, curing and other processes made of sheet metal. These two materials are national A-class fire-resistant materials, is a good performance of new construction and industrial sheet, the fire, moisture, heat insulation, anti-moth, durability are good, can be applied to all areas.
