Flotability and flotation separation of polymer materials modulated by wetting agents

Flotability of polymer materials modulated by wetting agents was studied, and wetting agents change significantly flotability of polymer materials. Flotation separation of plastic mixtures was conducted based the flotability modulated by wetting agents. The multicomponent plastic mixtures can be efficiently separated through multi-stage flotation using TA and LS as wetting agents, and the purity of separated component was above 94%, and the recovery was more than 93%.
