Preparation method of lightweight plastering gypsum
The invention provides a preparation method of light plastering gypsum. By stirring and mixing the building gypsum, the II anhydrous anhydrite, the self-made lightweight gypsum sand and the auxiliary agent according to a specific ratio and other operations, the mechanical strength of the prepared lightweight plastering gypsum can reach the excellent performance that the tensile adhesive strength is 0.7-1.0 MPa in a standard state and the tensile adhesive strength is 0.3-0.6 MPa in a humid state, for example, the mechanical strength of the lightweight plastering gypsum can reach the excellent performance that the tensile adhesive strength is 0.7-1.0 MPa in a standard state and the tensile adhesive strength is 0.3-0.6 MPa in a humid state. And compared with the existing light plastering gypsum with the tensile adhesive strength being greater than or equal to 0.4 MPa in a standard state, the light plastering gypsum has the advantage that the tensile adhesive strength is greatly improved.
本发明提供一种轻质抹灰石膏的制备方法。通过将特定配比的建筑石膏、II无水硬石膏、自制的轻质石膏砂、和助剂经过搅拌混合等操作，制成的轻质抹灰石膏的机械强度能够达到例如标准状态下拉伸粘结强度为0.7‑1.0MPa，潮湿状态下拉伸粘结强度为0.3‑0.6MPa的优良性能，相比较于现有的轻质抹灰石膏标准状态下拉伸粘结强度≥0.4MPa得到了较大改善。
