Manufacturing method of leveling gypsum mortar
The invention discloses a leveling gypsum mortar production method, which comprises: preparing raw materials, including 700-800 parts of phosphogypsum, 80-100 parts of heavy calcium powder, 50-80 parts of dried sand, 30-50 parts of 425 white cement, 1-1.5 parts of a retarder, 1-2 parts of a lubricant, 3-4 parts of cellulose ether, 0.5-0.7 part of starch ether, 2-3 parts of wood fiber, and 1.5-2 parts of polyvinyl alcohol; s2, filtering the raw materials, screening the powder raw materials through a screen, and screening out impurities in the powder raw materials to prevent the impurities in the raw materials from affecting sufficient fusion of the mortar. According to the method, proper wood fibers are injected in the secondary stirring process, through the structural viscosity of the wood fibers, the uniformity of the prefabricated slurry is kept in an original state and stable, and the shrinkage and expansion of a system are reduced, so that the fluidity loss is effectively reduced during mortar construction, and the utilization rate of the raw materials is further improved.
本发明公开了一种找平石膏砂浆制作方法，包括以下步骤：原料准备，磷石膏700‑800份、重钙粉80‑100份、烘干砂50‑80份、425白水泥30‑50份、缓凝剂1‑1.5份、润滑剂1‑2份、纤维素醚3‑4份、淀粉醚0.5‑0.7份、木质纤维2‑3份和聚乙烯醇1.5‑2份；S2：原料过滤，将上述的粉剂原料通过筛网进行筛选，将粉剂原料中的杂质筛除，防止原料中的杂质影响砂浆的充分融合。本发明中通过在二次搅拌过程中注入适当的木质纤维，通过木质纤维的结构粘性，使预制浆料的均匀性保持原状稳定并减少系统的收缩和膨胀，从而在砂浆施工时有效降低了流动度损失，进而提高了原料的利用率。
