The plastering anhydrite was prepared by fluorine plaster
Fluoropoulium gypsum by grinding, adding activator, plasticizer, water retaining agent and other admixtures for forced mixing, that is, F-type plaster gypsum. F-type plaster plaster has strong adhesion, stable volume after hardening, and is not easy to produce dry shrinkage cracks, drum and other phenomena. It can fundamentally overcome the common problems such as large dry shrinkage, poor adhesion, cracking and shell of traditional plastering materials such as cement mixed mortar and lime mortar. It also has the function of fire prevention, and can adjust indoor temperature within a certain range. At present, the use of stucco plaster is very common in many industrial developed countries. For example, more than 70% of the plastering material in Germany is stucco plaster, and the UK stucco plaster accounts for 50% of the total gypsum. The research and development of Chinese PLASTER began in the 1980s, and at present, Chinese plaster master
If semi - water gypsum based single - phase or mixed phase plaster plaster. Natural anhydrous gypsum (type II anhydrous gypsum) is used as the main raw material, mixed with composite activator for modification, to adjust the setting time and flexural and compressive strength, and then supplemented with an appropriate amount of composite water retention
Agent, fly ash admixture, air entraining agent, etc., grinding and mixing can be used to obtain plaster plaster for plastering. The test shows that the technical performance indexes of the plaster plaster meet the requirements of the national industry standard, and the strength and stability of the plaster plaster are obviously better than that of the plaster plaster produced by the building plaster.
