June 30, 2025 – Driven by carbon neutrality goals, the gypsum building materials industry is entering a critical phase of technological advancement and green transformation. Chinese enterprises have achieved core technological breakthroughs in gypsum retarders through independent R&D, breaking international monopolies and injecting new momentum into solid waste recycling and building energy efficiency.
I. Technological Innovation: Alkali-Resistant Retarders Lead Industry Transformation
Impurity Challenge Solved: Shenghui Fine Chemicals’ newly developed alkali-resistant gypsum retarder specifically addresses impurities and performance instability in phosphogypsum, significantly improving the utilization rate of desulfurization gypsum and phosphogypsum to advance solid waste recycling.
Strength-Setting Time Balance: Next-generation protein-based retarders (e.g., KH-GR801, SGR-1801) extend setting time by several hours at ultralow dosages (0.02%-0.35%) without compromising final strength-overcoming the strength loss associated with traditional citric acid retarders.
Enhanced Process Compatibility: Compatible with natural gypsum, industrial by-product gypsum, and diverse applications including self-leveling mortar, gypsum boards, and prefabricated components.
II. Green Transition: Phosphogypsum Upcycling Gains Momentum
Tech-Driven Waste Valorization: Xinyangfeng Group converts phosphogypsum into high-purity alpha gypsum and spherical cement retarders through flotation purification and autoclaved crystal transformation, achieving >90% impurity removal with annual processing exceeding 4 million tons.
Industrial Closed-Loop Model: Adopting an “industrial park + entrepreneurship” model (e.g., Jingmen Phosphogypsum Green Building Materials Industrial Park), downstream enterprises produce terminal products like gypsum-based self-leveling compounds and lightweight plaster, forming resource circulation chains.
III. Industry Landscape: Localization Accelerates
Breaking International Monopolies: Companies like Shenghui Fine Chemicals export alkali-resistant retarders to Southeast Asia, the Middle East, and Europe with >30% annual export growth, outperforming global brands in cost competitiveness.
Industry-Academia Collaboration: Leading firms partner with Hebei University of Engineering and Zhejiang University of Science & Technology, establishing “Technology Breakthrough Awards” to accelerate patent commercialization, with R&D investment reaching 10% of annual profits.
IV. Market Outlook: Policy and Demand Dual Drivers
Policy Support: Upgraded national green building standards boost retarder adoption in waterproof mortar, decorative gypsum, and related fields.
Application Expansion: Prefabricated construction growth drives demand for gypsum-based materials, increasing retarder usage in precision applications like machine-sprayed plaster and joint fillers.
