The process of the treatment process is complex and harsh, so that the production cost of phosphorus chemical enterprises is high, the profit is low, and the large-scale production is difficult to realize.
In view of this, how to increase the additional value of the industrial byproduct gypsum, expand the application range of the industrial byproduct gypsum, simplify the process flow, and obtain high attention of the related technicians in the phosphorus chemical industry. The existing plastering gypsum using industrial byproducts as a main material has the problem of poor quality, which is mainly reflected in cohesive force, surface finishing property, fire resistance, heat preservation and insulation, setting time, strength, light weight and the like, and the problems seriously affect the service quality and the service life of the plastering gypsum. The prepared plastering gypsum has poor surface bonding force, hollowing and cracking on the surface and poor heat preservation effect. The initial setting time is more than or equal to 1, the final setting time is less than or equal to 8, the water retention rate is more than or equal to 75%, the compressive strength is more than or equal to 4, the tensile bonding strength is more than or equal to 0.4, the volume density is less than or equal to 1400 and other industrial standards cannot be met. The existing plastering gypsum generally adopts additional foam to improve the heat preservation effect of the plaster, however, after physical plastering, the additional foam is inevitably broken, thereby affecting the performance of the whole slurry, and limiting the application of the foam on the light plastering gypsum.
