Gypsum as a building material has a long history, with light quality, smooth and delicate surface, high strength, good heat preservation and insulation, good fire prevention, low energy consumption, adjustable indoor temperature, sound insulation effect and other excellent performance, is a kind of green building materials.
At present, with the rapid development of construction industry in China, the demand of gesso building materials is growing sharply, and then present our country mainly from the exploitation of natural gypsum for gypsum building materials production raw material, not only the high cost, high energy consumption, and caused serious damage to the ecological environment, to that end, countries strongly advocated for chemical production of chemical by-product gypsum comprehensive utilization of resource, Expand the source of gypsum raw materials, relieve the pressure of resource constraints, and prevent industrial gypsum accumulation caused by environmental pollution, protect the ecological environment.
