Semi-hydrated phosphogypsum gel material as well as preparation method and application thereof
The invention belongs to the technical field of ardealite, and particularly relates to a semi-hydrated ardealite gel material as well as a preparation method and application thereof. The semi-hydrated phosphogypsum, the alkaline activator and the water reducing agent are used for preparing the gel material, a good retarding effect can be achieved while the water consumption is reduced, the silicic acid compound and the crystal form regulator with the succinic acid group and the silane group are introduced, and through cooperation of the silicic acid compound and the crystal form regulator, the retarding effect is good. A cementation network can be provided for dihydrate gypsum crystals, and the connecting force is increased, so that the strength of gypsum products is improved. Therefore, the semi-hydrated phosphogypsum gel material provided by the invention can ensure the mechanical properties of the gel material on the premise of reducing the water consumption and prolonging the setting time.
本公开属于磷石膏技术领域，具体涉及一种半水磷石膏凝胶材料、及其制备方法和应用。利用半水磷石膏、碱性激发剂、减水剂制备凝胶材料，在减少用水量的同时能够起到较好的缓凝效果，通过引入硅酸类化合物和具有丁二酸基团和硅烷基团的晶型调节剂，通过硅酸类化合物和晶型调节剂的配合，能为二水石膏晶体提供胶结网络，增加连结力，从而提高石膏制品强度。因此，本公开提供的半水磷石膏凝胶材料在降低用水量、延长凝结时间的前提下还能够保证凝胶材料的力学性能。
