Water-based polymer modified ardealite powder surface method and modified ardealite powder
The invention relates to the technical field of gypsum modification, in particular to a water-based polymer modified ardealite powder surface method and modified ardealite. The characteristic that a water-based polymer modifier is good in compatibility with attached water on the surface of ardealite is utilized, the attached water-containing ardealite is directly added into the water-based polymer modifier to be stirred and mixed, on the premise of containing attached water, the water-based polymer modifier is more uniformly distributed on the surface of the ardealite powder, the effect of modifying the ardealite powder by the water-based polymer modifier is better, and the temperature during stirring and mixing is controlled to be 30-70 DEG C, so that the flowability of the water-based polymer modifier is improved, meanwhile, the water-based polymer modifier can be promoted to cure and wrap the ardealite powder, the softening coefficient of the ardealite powder is improved, and the strength of the ardealite powder is improved after the ardealite powder encounters water.
本发明涉及石膏改性技术领域，尤其是一种水性高分子改性磷石膏粉体表面方法及改性磷石膏，利用水性高分子改性剂与磷石膏表面附着水相容性好的特点，实现将含附着水的磷石膏直接采用水性高分子改性剂加入搅拌混合处理，使得在含附着水的前提下，水性高分子改性剂在磷石膏粉体表面的分布更加均匀，促使磷石膏粉体受到水性高分子改性剂改性处理的效果更佳，且经控制搅拌混合时的温度介于30‑70℃，提高水性高分子改性剂的流动性，增强与石膏粉体附着的均匀性，同时还能够促进水性高分子改性剂固化包裹磷石膏粉体，达到改善磷石膏粉体的软化系数和遇水后强度改善等性能。
