2025 04/17

Recently, nine research and development projects in 2024 of the Green Environmental Protection Industry Co., Ltd. under Guizhou Phosphorus Chemicals Group have passed the final acceptance inspection. Among them, six achievements have realized technological transformation and entered the mass production stage. These technological breakthroughs mark an important progress in the resource utilization of phosphogypsum by Guizhou Phosphorus Chemicals Group, providing innovative solutions for solid waste treatment and the development of green building materials.
 
The nine projects accepted this time cover key topics such as "Research on the Expansion of Large-scale Application of Anhydrite" and "Development and Industrial Application of the Masonry-type Fully Assembled Gypsum Wall (Component)", forming a complete technology chain from raw material preparation, material modification to end products. Through methods such as listening to reports and conducting inquiries and discussions, the expert group determined that the relevant technological achievements meet the conditions for industrialization, and some products have achieved large-scale production.

Among them, six products, including anhydrite packaging boxes and gypsum-based self-leveling materials, have entered the mass production stage and are expected to be promoted and applied in industries such as logistics and construction. These technological breakthroughs not only improve the comprehensive utilization rate of phosphogypsum but also promote the improvement of the industry standard system, providing a systematic solution for the high-value utilization of phosphogypsum.

Through the cooperation model of industry, university and research institute, the Green Environmental Protection Company and the team of Academician Qu Jinping from South China University of Technology jointly established a joint laboratory, successfully overcoming key technologies such as the development of functional masterbatches of phosphogypsum and the molding of ultra-high molecular weight polyethylene pipes.

At present, Type II anhydrite and its products, high-precision gypsum blocks, building decoration materials, and prefabricated composite building materials products have been selected into the Recommended Catalogue of the Action Plan for the Comprehensive Utilization of Phosphogypsum, providing a solution from Guizhou Phosphorus Chemicals Group for solving the difficult problem of the resource utilization of phosphogypsum.
