Research Abstract

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.
