Perlite plate, floating bead plate, slate plate: hollow plate made of low alkalinity cement as base material, perlite, glass microbead and vermiculite as aerated filling material, and then added with some additives. It has the characteristics of light weight, high strength, good toughness, fireproof and heat insulation, convenient construction, etc. It can be widely used in non-load-bearing parts such as high-rise frame building compartments, households, bathrooms, kitchens, communication pipes, etc. Fireproof gypsum board: Since the fireproof performance of gypsum has been widely accepted, fireproof board based on gypsum has developed rapidly. The main component of the plate is non-combustible and contains crystal water, and has good fire resistance, and can be used as a partition wall, a ceiling and a roof panel. The sheet material is rich in raw materials and is convenient for factory final production. In use, it has light weight, can reduce building load-bearing, and is easy to process, can be sawed and planed, convenient in construction and good in decoration, but its bending resistance is poor. There are many factors affecting the fire resistance of gypsum board, such as composition, type of board, type of keel, thickness of board, presence or absence of filler in air layer, and assembly method. In recent years, new varieties such as silicon-calcium gypsum fiberboard and double-sided sticker plaster fireproof panels have appeared.
