Abstract

According to the compression-resistant light plastering gypsum mortar and the preparation method thereof, the mixed gypsum powder serves as a main component, and basic strength support is provided for materials. Due to the addition of the vitrified micro-beads, the characteristics of internal porosity and surface vitrification sealing of the vitrified micro-beads ensure the light weight of the material, the compressive strength and breaking strength of the material can be effectively enhanced, the stability of the whole structure is improved, and the material is not easy to damage when bearing external force; the anti-cracking performance is changed, the growth form and structure of gypsum crystals can be regulated and controlled, the crystals are more uniform and compact, the stress concentration among the crystals is reduced, the anti-cracking performance of the material is effectively improved, and the stable and consistent performance of products produced in each batch is ensured through the precise raw material ratio and a strict quality control system. The high standard requirements can be met in terms of key performance indexes such as strength, crack resistance, water resistance and the like and in terms of appearance quality, and reliable product guarantee is provided for consumers.
