Low cost, high flatness, high-quality gypsum based self leveling technology and formula

Low cost, high flatness, high-quality gypsum based self leveling technology and formula -2023 First Gypsum Based Self leveling High Quality Development Forum

On July 18, 2023, the Gypsum based Self leveling High Quality Development Forum was successfully held in Suzhou. At this grand event, numerous industry experts and representatives from upstream and downstream enterprises jointly discussed the future development trends of gypsum based self leveling mortar, as well as how to improve product quality and core competitiveness of enterprises, and promote the healthy development of the industry。

Meeting venue

The topic of the report by Yang Jiaguo, Technical Director of Hubei Zhimeitang, at this forum is "Low cost, High flatness, High quality Gypsum based Self leveling Technology and Formula". The report systematically introduces the measurement standards, typical raw materials, and formulas of high-quality gypsum based self leveling, and shares Zhimeitang's views on the future development of gypsum based self leveling products.

Zhimei Tang Director Yang's Technical Sharing

High quality gypsum based self leveling mortar should not only meet relevant standards and usage requirements, but also have stable quality, easy construction, high flatness, beautiful surface layer, good durability, and low cost. Gypsum has a high threshold and is more complex than cement. To achieve good gypsum based self leveling, it is necessary to study raw materials, products, and construction standards, and start from research and development, production, and construction in all aspects. In the report, Director Yang elaborated on the technical difficulties of gypsum based self leveling and the roles and characteristics of each component in the formula, starting from the issue of raw materials. In the report, Director Yang also shared a case study of Zhimeitang laboratory using DIN viscosity cup to test the viscosity of self leveling slurry to characterize its workability, as well as the new generation of water retaining stabilizer S750 developed by Zhimeitang.

DIN viscosity cup is generally used for determining the viscosity of coating products, and there is a relatively complete standard system. The principle is to test the time for mortar to flow out of the viscosity cup with an opening. The shorter the time, the faster the flow velocity of the mortar, the lower the viscosity value, and the better the flow performance. This is also the first time in China to propose using DIN viscosity cups to test the self leveling viscosity of gypsum based materials. forty

S750 belongs to the shear thinning stabilizer, used for flow system mortar, which can improve the flowability and water retention of mortar, resist segregation and bleeding, and enhance the stability of slurry. Zhimeitang conducted a large number of self leveling tests using phosphogypsum and other gypsum produced by Xinyangfeng Jingmen Factory. The gypsum base stabilized with S750 was self dispersing and easy to add water, with good suspension stability, less oil pollution, high flatness, and significantly reduced cost.

At the end of the report, Director Yang mentioned that the development of high-strength alpha gypsum and type II anhydrous gypsum technology is very fast, and the investment and production costs have been greatly reduced. With the maturity of technology, it will also be widely applied in the gypsum industry, and the gypsum based self leveling industry will eventually develop towards high quality, multi-purpose, and low cost.

The high-quality development forum of gypsum based self leveling has been a complete success. Guided by the principle of "selecting qualified gypsum and additives, paying attention to new technologies, and continuously optimizing formulas", Zhimeitang will continue to devote itself to the technology and innovation in the field of low-cost and high flatness gypsum based self leveling, and contribute to the creation of a high-quality gypsum based self leveling industry.
