Lightweight desulfurized plastering gypsum and preparation method thereof
The invention provides light desulfurized plastering gypsum and a preparation method thereof, and belongs to the technical field of plastering gypsum. The light desulfurized plastering gypsum comprises the following components: raw materials, a desulfurizer, a modifier and a control agent, the raw materials comprise 65-95 parts by weight of a gypsum raw material, 15-30 parts by weight of expanded perlite and 8-10 parts by weight of a biomass material; the desulfurizing agent is a particle encapsulation desulfurizing agent and comprises a built-in sodium hydroxide medicament, a wall material prepared from gelatin and an embedding agent which is used for promoting solidification and is prepared from aluminum potassium sulfate; the modifier comprises a plasticizer and a flexibilizer, and the weight ratio of the plasticizer to the flexibilizer is 1: 1. The sodium hydroxide, the gelatin and the aluminum potassium sulfate are prepared into capsule particles, so that the action time of the sodium hydroxide in the desulfurization process is prolonged, and the desulfurization efficiency is improved.
本申请提供了一种轻质脱硫抹灰石膏及其制备方法,属于抹灰石膏技术领域。本申请所述轻质脱硫抹灰石膏的组成成分包括原材料、脱硫剂、改性剂和控制剂;所述原材料包括65‑95重量份的石膏原料、15‑30重量份的膨胀珍珠岩、8‑10重量份的生物质材料;所述脱硫剂为颗粒胶囊化脱硫剂,所述脱硫剂包括内置的氢氧化钠药剂、明胶制成的壁材料和用于促进固化的、硫酸铝钾制成的包埋剂;所述改性剂包括增塑剂和增韧剂,所述增塑剂和增韧剂的重量比为1:1。通过将氢氧化钠、明胶和硫酸铝钾制成胶囊颗粒,增加氢氧化钠在脱硫过程中的作用时间,从而提高脱硫效率。
