Calcium silicate board, as a new type of green and environmentally friendly building material, not only has the functions of traditional gypsum board but also boasts superior fire-resistant properties, moisture resistance, and an exceptionally long service life. It is widely used in the ceiling and partition walls of commercial and industrial construction projects, home renovations, furniture backing boards, billboard backing boards, warehouse roof panels, network floors, and wall panels for indoor tunnels and other projects. Calcium silicate board is reinforced with loose short fibers such as inorganic mineral fibers or cellulose fibers.-Calcium-based materials serve as the main binder, processed through pulping, shaping, and accelerated curing reactions in high-temperature, high-pressure saturated steam, resulting in calcium silicate gel bodies. This is a new type of building and industrial board with excellent properties, offering fire resistance, moisture resistance, sound insulation, termite prevention, and good durability, making it an ideal decorative board for ceilings and partitions.
