Building decoration fireproof board is usually a composite material with inorganic materials as the main body, such as various gypsum boards. The hardened dihydrate gypsum contains 21% crystal water. When encountering a fire, it will come out of the crystal well to absorb a lot of heat energy. The evaporated water forms a vapor curtain on the surface of gypsum products, which can prevent the spread of fire. Anhydrite after dehydration is still a poor conductor and flame retardant. The greater the thickness of gypsum products, the better their fire resistance performance. Due to the good fire resistance characteristics of building gypsum, gypsum products are widely used in various modern buildings, especially in the walls and ceiling of high-rise buildings, fiber cement board manufacturers. In addition, high temperature expansive vermiculite, expanded perlite, microporous pearl calcium and foam glass, mineral wool, glass wool, and polychloroethylene foam plastics with water self extinguishing properties are combined with fire-resistant plates made of water glass, cement and other chemical additives with good heat resistance, and are also widely used in various industrial and civil buildings.
The paper faced gypsum board (hereinafter referred to as gypsum board) is a thin plate made of gypsum and other additives such as appropriate fiber, adhesive, accelerator and retarder as the core, board paper as the cover, prepared by slurry preparation, molding, cutting and drying. It has high quality and strength, earthquake resistance, fire prevention, insect proofing, heat insulation, sound insulation, good processability and decoration beauty It is an ideal new building wall material, which can be used for internal partition wall, wall cladding panel, ceiling and composite partition board in industrial and civil buildings.
