High strength gypsum based water resistant self-leveling mortar is made of industrial by-product gypsum as the base material, combined with ultrafine inorganic fillers, a variety of polymer modified initiators and multi-level aggregate processing. After blending with water, it forms a high fluidity slurry, which can be constructed manually or poured mechanized in large areas, and can realize automatic and precise leveling of the ground. Compared with traditional leveling materials and traditional cement-based self-leveling materials, the material performance is more superior, the application process is more simple and efficient, our company for the strong new materials Group in 2020 to build the local benchmark gypsum based mortar production line - Henan Gaisen Material Technology Co., LTD., is an energy saving, environmental protection, high-tech intelligent green factory. It is a demonstration base for high-value utilization of industrial by-product gypsum in Jiaozu City, mainly producing light plaster plaster and gypse-based self-leveling mortar. The self-leveling mortar produced by it has been distributed all over the country and exported abroad. The following figure shows the gypse-based self-leveling mortar produced by it applied to the construction of Shanghai Cell Therapy Group with construction thickness of 80mm, strength of C25 and flatness of -2-0.
