AI Technical Summary
Technical Problem
Existing technologies have low fluoride spillover and recovery rates, resulting in underutilization of fluorine resources and a lack of effective optimization of related processes.
Method used
An additive is mixed with a silicon-rich substance, and the overflowing gaseous fluoride is recovered through a heating reaction. The chemical structure and properties of the additive reduce interfacial tension, enhance dispersibility and permeability, and increase the fluoride overflow rate.
Benefits of technology
It significantly improves the fluorine spillover rate, enhances the quality of phosphoric acid, and the process is simple and easy to implement, making it suitable for various fluorine-containing industrial processes.
