Separation of the mixture of shredded acrylonitrile-butadiene-styrene and polyamide by flotation method using sulphanole and synthanol as sufractants

Abstract

A method of flotation separation of a mixture of widely used polymers acrylonitrile butadiene styrene and polyamide was analyzed. The experiments were performed on a laboratory flotation turret with air aeration of the pulp. The formulas of key indicators flotation are presented. In this case, we obtained the dependencies of the concentration of surface-active substances, and the air flow on the purity concentration and extraction of float component. The optimal conditions for the flotation process of the polymer mixture were determined. It is concluded that the flotation separation of polymers based on their selective wettability is promising for the processing of mixed plastic waste.
