Architectural fibrous gypsum board taking phosphorus slag as matrix
A preparation method of the building fiber gypsum board comprises the following steps: calcining the phosphorus slag in a high-temperature furnace to obtain phosphogypsum powder, adding an alkali activator, cement and sand to prepare a mixture I, adding a fiber material to form a mixture II, and pouring the mixture II into a mold to obtain the phosphogypsum board. The invention has the following beneficial effects: a building gypsum board product with functions of crack resistance, corrosion resistance and the like is provided for the market; meanwhile, the invention provides the method for directly preparing the building gypsum board from the phosphorus slag, the gypsum product is prepared on the premise that the phosphorus slag is directly used as the raw material, solid waste can be effectively consumed, economic benefits and environmental protection value are generated under the condition that new pollution is not generated, and a comprehensive phosphogypsum utilization way capable of being popularized is formed.
本发明涉及一种以磷渣为基质的建筑用纤维石膏板材，制备方法包括以下步骤：在高温炉内煅烧磷渣得到磷石膏粉，加入碱激发剂、水泥和砂制成混合料一，加入纤维材料，形成混合料二，倒入模具，得到磷石膏板。本发明的有益效果是：为市场提供了一种具有抗裂，防腐等功能的建筑用石膏板材产品；同时提供了这种由磷渣直接制备建筑石膏板材的方法，在直接使用磷渣作为原料的前提下，制备石膏制品，可以有效消耗固体废弃物，在不产生新污染的情况下产生经济效益和环保价值，形成一种可推广的磷石膏综合利用途径。
