Abstract

The results of investigations of electrostatic separation of mixtures of polylactide (PLA) with poly(ε-caprolactone) (PCL) and PLA with poly(vinyl chloride) (PVC) or poly(ethylene terephthalate) (PET) are presented. Four input quantities of the process, having abasic influence on the effects of electrostatic separation of the investigated mixtures, were examined: (a) mass fraction of the individual components, (b) fluidized-bed charging time, (c) potential difference between the electrodes, (d) rotational speed of the roll electrode. The mathematical models of electrostatic separation process of PLA, PCL, PVC and PET mixtures were developed and analyzed. It was found that these models can be used in practice for analysis of separation of these mixtures.
