摘　　要：以磷酸厂排放的工业废渣磷石膏为原料,探讨其转化为建筑石膏的工艺过程,确定炒制制度,并以此为基材研制磷石膏基建筑抹面材料。该抹面材料主要由磷石膏、填料、细分散有机聚合物及化学添加剂等组成,开辟了磷石膏资源化的新途径。The possibility of transforming phosphogypsum into calcined gypsum has been studied. The properties of phosphogypsum have been analyzed and the best technological procedure of changing phosphogypsum into calcined gypsum has been determined. By pre-treating phosphogypsum and eliminating some impurities, we can get β-type gypsum. Using this material and other additives, we produce a new phosphogypsum building plaster with higher additional value.
