The Impact of Surfactants on Separation of Mixed Polymer Wastes in Electrostatic Field

Abstract

A quantitative analysis is carried out of such factors as electrostatic intensity, surface area of particles, dielectric permittivity, size polymer particles, and the type and concentration of surfactants, by the amount of electric charge of the polymer surface, obtained in the electrostatic field after their pre-treatment of surfactants. Dependencies of the maximum charge of polymer waste particles from the basic technological parameters of the drum electrostatic separator and physical-chemical properties of polymers and surfactants are shown. It has been found that degradation of polymeric waste in a surfactants aqueous solutions is an effective preliminary step of technology of electrostatic separation of a mixture of crushed polymer wastes that positive effect on their charging in an electrostatic field. The obtained data allows to develop the technological process precision selective separation of mixed polymer materials in an electrostatic field.
