Coagulating agent special for type gypsum and preparation method thereof
The invention discloses a special coagulant for a-type gypsum and a preparation method of the special coagulant. The special coagulant is prepared from the following raw materials in parts by weight: 280-320 parts of potassium sulfate, 90-110 parts of anhydrite and 90-110 parts of a polycarboxylate superplasticizer. According to the present invention, in the use of the type a gypsum building material product, the coagulation accelerator is doped according to different ratios, the same water consumption is used, the initial setting time and the final setting time are shortened, the water consumption of the raw powder is not changed, the initial setting time and the final setting time are advanced by about 8-9 min, the construction is simple, the strength is improved, the construction cost is saved, the product quality is improved, and the problems of "etc." in the construction process are solved.
本发明公开了一种专用于a型石膏的促凝剂及其制备方法，由以下重量份的原料制成：硫酸钾280～320份、无水石膏90～110份、聚羧酸减水剂90～110份。本发明在使用a型石膏建材产品中，按不同比列掺入促凝剂，用相同的用水量，缩短初终凝时间，在不改变原粉的用水量，使初终凝时间提前8～9min左右，且施工简单，提高强度，节约施工成本，提高产品质量，解决了在施工过程中“等”的难题。
