Efficient preparation method of titanium gypsum for cement
The invention discloses an efficient preparation method of titanium gypsum for cement, which belongs to the technical field of building material preparation, and comprises the following steps: dissolving titanium gypsum in water to prepare titanium gypsum slurry with a certain mass fraction; adding an acid solution with a certain volume and concentration into the prepared titanium gypsum slurry; and stirring the titanium gypsum slurry added with the acid solution at a certain temperature for a certain time, precipitating, filtering, washing, drying and grinding to obtain the titanium gypsum for cement. Compared with the prior art, the titanium gypsum prepared by the invention can completely replace natural gypsum or desulfurized gypsum to be used as a retarder of cement, and has no negative influence on related properties of the cement. Meanwhile, the content of sulfur trioxide (SO3) in the titanium gypsum prepared by the method is relatively high, so that the use amount of gypsum is effectively reduced, and the production cost of cement is saved. In addition, the method is simple, easy to operate, high in efficiency and low in cost, and has great industrial popularization value.
本发明公开了一种水泥用钛石膏的高效制备方法，属于建筑材料制备技术领域，所述方法包括步骤为：将钛石膏溶于水中制成一定质量分数的钛石膏料浆；向制成的钛石膏料浆中加入一定体积和浓度的酸溶液；将加入酸溶液后的钛石膏料浆在一定温度下搅拌一定时间后，沉淀、过滤、洗涤、干燥、粉磨，即得到水泥用钛石膏。与现有技术相比，本发明所制备的钛石膏能够完全替代天然石膏或脱硫石膏作为水泥的缓凝剂，且对水泥的相关性能没有负面影响。与此同时，该方法制备的钛石膏三氧化硫(SO3)含量较高，有效降低了石膏的使用量，节约了水泥生产成本。此外，该方法简单、易操作，效率高、成本低，极具工业推广价值。
