The invention provides fluorgypsum powder, a preparation method and a prepared gypsum block, and relates to the technical field of gypsum. The fluorgypsum powder is prepared from 10-20 parts by weight of limestone, 45-65 parts by weight of fluorgypsum and 20-40 parts by weight of desulfurized gypsum, the finished product is high in strength and short in setting time, the utilization rate of the fluorgypsum can be greatly increased, and the resource conversion rate is high. In addition, the invention further provides a preparation method of the fluorgypsum powder, the fluorgypsum powder which is uniformly mixed and small in particle size can be prepared in a simple and rapid mode, the preparation cost is low, the preparation period is short, and the fluorgypsum powder is suitable for batch production. In addition, the invention further provides the gypsum block which can be directly prepared from the fluorgypsum powder, the strength of the gypsum block meets the building use standard, and the gypsum block is easy to prepare and wide in application environment.
本发明提出一种氟石膏粉、制备方法及制备的石膏砌块，涉及石膏技术领域。该氟石膏粉由10‑20重量份的石灰石、45‑65重量份的氟石膏以及20‑40重量份的脱硫石膏制备而成，不仅成品的强度较高、凝结时间较短，而且能够大大提升氟石膏的利用率，资源转化率较高。另外，本发明还提供一种氟石膏粉的制备方法，其能够以一种简单、快速的方式制备出一种混合均匀且粒径较小的氟石膏粉，不仅制备成本较低，而且制备周期较短，适合批量生产。除此之外，本发明还提供一种石膏砌块，其能够直接由氟石膏粉制备而得，不仅强度符合建筑使用的标准，而且制备简单，适用环境较广。
