Problems solved by technology

[0003] During the use of stucco plaster, anhydrous gypsum, yellow sand and cement are added to the mixer first, and then other ingredients are added. The disadvantage of this operation is: once there is a measurement or timing error, the proportion of other ingredients The impact is greater, and the way other ingredients are added later can easily cause uneven mixing, and long-term mixing will affect production efficiency, especially for the production of plaster gypsum containing vitrified microbeads. Therefore, the wall plaster plaster produced by the traditional process often has the problems of large site pollution and many consumables during wall construction.

Abstract

The invention relates to the technical field of building gypsum preparation, and discloses a preparation raw material of high-performance environment-friendly gypsum, the preparation raw material comprises a bottom layer plastering gypsum main material and a bottom layer plastering gypsum auxiliary material, the bottom layer plastering gypsum main material comprises anhydrite, yellow sand and cement; the bottom layer plastering gypsum auxiliary material comprises glass beads, industrial aluminum sulfate, industrial potassium sulfate, cellulose and calcium powder; the invention relates to a preparation method of high-performance environment-friendly gypsum. The preparation method comprises the following working steps: 1, purchasing raw materials and arranging a bag-type dust removal system; 2, feeding of the main materials and the auxiliary materials; and 3, mixing the main materials and the auxiliary materials. In the invention, when the main material and the auxiliary material are mixed, the glass beads, the industrial aluminum sulfate, the industrial potassium sulfate, the cellulose and the calcium powder are firstly added, so that timing errors are reduced, timing accuracy is ensured, the glass beads, the industrial aluminum sulfate, the industrial potassium sulfate, the cellulose and the calcium powder are uniformly mixed, the production efficiency is improved, the integrity of the glass beads is ensured, and the quality of a finished product is improved.

Description

technical field [0001] The invention relates to the technical field of building gypsum preparation, in particular to a preparation method of high-performance and environment-friendly gypsum. Background technique [0002] Gypsum plaster is mainly used for plastering various walls and ceilings in buildings, and is not suitable for toilets, kitchens and other places that are often in contact with water. According to the application, it is divided into surface plaster (F), bottom plaster (B) and Insulation layer plaster (T), wherein: the surface plaster (F) usually does not contain aggregates and is used for plastering plaster or other outermost layer of plastering materials on the substrate; the bottom plaster usually contains aggregates and is used for The base is leveled; the insulation layer is painted with gypsum, which has good thermal insulation. [0003] During the use of stucco plaster, anhydrous gypsum, yellow sand and cement are added to the mixer first, and then oth...
