AI Technical Summary
Existing technologies for treating phosphogypsum present problems such as high leakage risk and complex processes, making it difficult to utilize phosphogypsum efficiently and safely, leading to environmental pollution.
The desulfurized glass melt is prepared and microcrystallized to obtain microcrystalline glass plates through mixing and melting of the ingredients. The process is simple and eliminates the pretreatment step. It uses phosphogypsum, quartz sand, soda ash, sodium fluorosilicate and feldspar as raw materials, and adds antimony powder and sodium nitrate as additives. The melting temperature and cooling rate are controlled, and sulfur-containing flue gas is treated by segmented spraying of ammonia.
This method enables the efficient and safe utilization of phosphogypsum to produce high-strength microcrystalline glass panels, reducing environmental pollution. The process is simple, and the microcrystalline glass panels can be used for building decoration, thus promoting the resource utilization of phosphogypsum.
