The separation of PVC and other chlorinated plastics from mixture of waste plastics was investigated and separation technology was developed. The mechanisms of hydrophilization of PVC surface was found and enhancement of hydrophilization of PVC surface was achieved at higher ozone concentration and ozonation time. Optimization of the condition of froth flotation was optimized and these technologies were applied to the improvement of wet density separation of PVC.

研究了从废旧塑料混合物中分离PVC等氯化塑料的方法，开发了分离工艺。研究了臭氧对PVC表面的氧化作用机理，发现臭氧浓度越高，氧化时间越长，PVC表面的氧化效果越好。对泡沫浮选条件进行了优化，并将其应用于PVC湿密度分选的改进。
