Description
Technical Field
The invention relates to the technical field of plastering gypsum, in particular to a preparation method of low-cost humidity-regulating plastering gypsum.
Background
The currently marketed bottom layer plastering gypsum is usually manufactured by mixing outsourced mixed sand and surface layer plastering gypsum in proportion, the product performance produced by the method has higher dependence degree on the stability of the sand, and if the supply quality of the sand is unstable, the product performance is greatly influenced. The thickness and mixing ratio of the sand, i.e., the sand grains of different grain sizes, greatly affect the performance of the plastering gypsum because of: in concrete, the surface of the sand needs to be covered by gypsum slurry, and the greater the total surface area of the sand, the more gypsum slurry needs to be covered on the surface of the sand. Under the condition of the same dosage, the total surface area of the fine sand is larger, and the total surface area of the coarse sand is smaller, while the traditional process usually adopts powdery quartz sand, and the powdery quartz sand brings the reduction of the cracking resistance after exceeding a certain thickness.
The invention has strict requirements on the quality of the sand, and carries out deep research and analysis on the gradation of the sand, so that the prepared product has strong bonding force, effectively inhibits the shrinkage cracking phenomenon in plastering, and better solves the common problems of hollowing cracking, falling off and the like of cement mortar and mixed mortar plastering. In order to reduce the cost and effectively prevent the shrinkage cracking, it is necessary to research a low-cost preparation method of the humidity-controlling plastering gypsum.
