Gelling material prepared from fluorgypsum and preparation method of cementing material
The invention relates to a cementing material prepared from fluorgypsum and a preparation method thereof, and belongs to the technical field of comprehensive utilization of solid wastes. The preparation method of the cementing material prepared from the fluorgypsum comprises the following steps: a, heating the fluorgypsum to 120-600 DEG C, and preheating for 10-25 seconds; b, boiling and calcining the fluorgypsum preheated in the step a at 700-900 DEG C; and c, cooling the fluorgypsum boiled and calcined in the step b to 60-100 DEG C, mixing the fluorgypsum with an exciting agent, and grinding to obtain the cementing material prepared from the fluorgypsum. According to the method disclosed by the invention, the fluorgypsum is used as a raw material to prepare the very high-quality cementing material, so that the fluorgypsum is recycled and harmless, and the method is an important way for promoting comprehensive utilization of industrial solid wastes, preventing and controlling pollution, protecting the environment and improving economic benefits in fluorine chemical industry.
本发明涉及一种氟石膏制胶凝材料及其制备方法，属于固体废弃物综合利用技术领域。所述氟石膏制胶凝材料的制备方法包括如下步骤：a.将氟石膏升温至120～600℃预热10～25S；b.将a步骤预热后的氟石膏在700～900℃沸腾煅烧；c.将b步骤沸腾煅烧的氟石膏冷却至60～100℃后，再与激发剂混合、磨粉得到氟石膏制胶凝材料。本发明的方法以氟石膏为原料制备得到了非常优质的胶凝材料，使氟石膏资源化和无害化，是氟化工推动工业固废综合利用，防治污染，保护环境，提高经济效益的重要途径。
