Production process of damp-proof phosphorus building gypsum board
The invention discloses a production process of a damp-proof phosphorus building gypsum board, and belongs to the field of building materials. The process comprises the steps of raw material mixing and stirring, gypsum board compression molding, preliminary cutting, negative pressure acid leaching treatment, negative pressure alkaline leaching treatment, drying, precise cutting and the like. The process provided by the invention is simple in technical route, the main raw materials are phosphorus building gypsum and wastewater discharged during industrial wet-process phosphoric acid preparation, the process is green and environmentally friendly, and the economic benefit is prominent; compared with a traditional production process of a water-resistant gypsum board, the process disclosed by the invention is inorganic and waterproof, and the fire resistance of a gypsum-based building material product is not reduced; and the gypsum board has waterproof performance in the structure, so that the overall waterproof performance is not influenced under the condition of local damage.
本发明公开了一种防潮磷建筑石膏板的生产工艺，属于建筑材料领域。本发明包括原料混合搅拌、石膏板压制成型、初步切割、负压酸浸处理、负压碱浸处理、烘干、精确切割等步骤。本发明所述工艺技术路线简单，主要原料为磷建筑石膏和工业湿法制备磷酸时所排放的废水，绿色环保，经济效益突出；相较于传统耐水石膏板的生产工艺，本发明所述工艺为无机防水，不降低石膏基建材制品的耐火性能；且石膏板具有结构内防水性能，在发生局部破损情况下不影响整体耐水性能。
