Method for producing gypsum plaster by using desulfurized gypsum
The invention discloses a method for producing gypsum plaster by using desulfurized gypsum. The method comprises the following steps of: S1, calcining, grinding, cooling and storing desulfurized gypsum; S2, taking the cooled desulfurized gypsum, mixing the cooled desulfurized gypsum with an additive and water, and then putting the mixture into a grinding tool to wait for solidification forming; and S3, after solidification forming, connecting the product with surface protection paper through glue, and carrying out solidification forming and drying treatment; In the step S1, the calcining temperature is 180 DEG C, and the calcining time is when the content of crystal water is detected to be 8-10%; In the step S2, the additive comprises 3-8 parts by weight of konjaku flour, 5-10 parts by weight of a water reducing agent, 1-5 parts by weight of a foaming agent and 2-6 parts by weight of a coupling agent, and the weight ratio of the additive to the water to the desulfurized gypsum is 10: 60: 110. In the step S3, the drying temperature is 220-250 DEG C, and the drying time is 30 min.
本发明公开了利用脱硫石膏生产纸面石膏的方法，括以下步骤：步骤S1：将脱硫石膏进行煅烧、磨料、冷却存储；步骤S2：取冷却后的脱硫石膏并月与添加剂、水混合后放入磨具等待凝固成型；步骤S3：凝固成型后通过胶与护面纸连接，并凝固成型，干燥处理；步骤S1中，煅烧温度为180℃，煅烧时间为检测到结晶水含量在8～10％之间；步骤S2中，添加剂包括3～8重量份的魔芋粉、5～10重量份的减水剂、1～5重量份的发泡剂、2～6重量份的偶联剂；添加剂、水、脱硫石膏的重量比为10:60:110；步骤S3种，干燥温度为220～250℃，干燥时间为30min。
