Method for preparing light plastering gypsum from regenerated polyurethane powder
The invention relates to the technical field of preparation of light plastering gypsum, and discloses a method for preparing light plastering gypsum from regenerated polyurethane powder. The light plastering gypsum is mainly prepared from the following substances in parts by weight: 0 to 200 kg/t of alpha semi-hydrated gypsum, 600 to 900 kg/t of beta semi-hydrated gypsum, 50 to 300 kg/t of heavy calcium powder, 1.5 to 2.5 kg/t of HPMC, 0.01 to 0.5 kg/t of a water reducing agent, 0.02 to 0.1 kg/t of an air entraining agent, 0.01 to 0.05 kg/t of a defoaming agent, 0.5 to 3 kg/t of a retarder, 0 to 100 kg/t of washed sand, 0 to 1000 L/t of regenerated polyurethane powder and 0 to 1000 L/t of perlite. The light plastering gypsum has the advantages of being low in manufacturing cost, easy to manufacture and renewable, solves the problem of waste utilization, is beneficial to environment protection and resource waste avoiding, and has the effects of being healthy, environmentally friendly and durable.
本发明涉及制备轻质抹灰石膏技术领域，并且公开了一种再生聚氨酯粉末制备轻质抹灰石膏的方法，主要由以下物质按重量份数比制成的：α半水石膏：0‑200kg/t、β半水石膏：600‑900kg/t、重钙粉：50‑300kg/t、HPMC：1.5‑2.5kg/t、减水剂：0.01‑0.5kg/t、引气剂：0.02‑0.1kg/t、消泡剂：0.01‑0.05kg/t、缓凝剂：0.5‑3kg/t、水洗砂：0‑100kg/t、再生聚氨酯粉末：0‑1000L/t、珍珠岩：0‑1000L/t；具有制作成本低、制作简易以且可再生的优点，解决了废物利用问题，有利于保护环境，避免资源浪费，具有健康环保、持久耐用的作用。
