Method for preparing high-strength fiber gypsum board by utilizing phosphogypsum
The invention relates to the field of solid waste recycling and the technical field of building material production, in particular to a method for preparing a high-strength fiber gypsum board from ardealite. The invention relates to a method for preparing a high-strength fiber gypsum board from phosphogypsum. The method comprises the following steps: S1, stir-frying beta-semi-hydrated phosphogypsum; s2, preparing fiber pulp; s3, preparing a wet gypsum mixture; s4, compression molding; and S5, natural curing. According to the gypsum board obtained through the preparation method, the breaking strength can reach 12 MPa or above, the breaking strength is obviously improved compared with that of a conventional fiber gypsum board, drying treatment is not needed in the preparation process, packaging and warehousing can be conducted, production is completed, the drying energy consumption cost is saved, and the production cost is reduced.
本发明涉及固体废物资源化领域和建筑材料生产技术领域，尤其涉及一种利用磷石膏制备高强度纤维石膏板的方法。一种利用磷石膏制备高强度纤维石膏板的方法，包括以下制备方法：S1、炒制β‑半水磷石膏；S2、配制纤维浆；S3、制备湿润石膏混合料；S4、压制成型；S5、自然养护。采用本发明所述制备方法得到的石膏板，抗折强度可达12MPa以上，较常规纤维石膏板的抗折强度具有明显提升，且制备过程不需要进行烘干处理，即可打包入库，完成生产，节约了干燥能耗成本，降低了生产成本。
