(1) Low production energy consumption. The cementitious gypsum used for the production of gypsum board has a unit production energy consumption 78% lower than that of cement. (2) Lightweight heat insulation, using a plasterboard as a partition wall, weighing only 1/3 of the brick wall. At the same time, due to the porous structure of the gypsum board, its thermal conductivity is 0.30, which is superior to brick (0.43) and concrete (1.63). (3) It has excellent fireproof performance, and its fire resistance limit can be more than 2 hours due to the release of the combined water when the gypsum is heated. (4) The decorative function is good, the surface of the gypsum board is flat, and the board and the board can be firmly bonded together by the cement material to form a seamless structure, and the architectural decoration effect is good. (5) Good workability, gypsum board can be nailed, sawable, viscous, and construction is very convenient. It can be used to decorate and can get rid of traditional wet operation and greatly improve construction efficiency. (6) Comfortable living function, because the gypsum board has unique "breathing" performance, it has the ability to adjust the humidity of the room, making the living comfortable. (7) High production efficiency. Conducive to mass production, gypsum board production efficiency is the highest in various building boards, which is convenient for mass production. (8) Low investment. Compared with fiber gypsum board, cement foam board and gypsum board, the production equipment of gypsum board can achieve continuous mechanized production, the equipment utilization rate is very high, and the equipment investment is small.
