Investigation of operational properties of epoxy-sand compounds used in repair of machines

Abstract

The results of a series of experimental studies of the properties of epoxy-sand compounds used in the repair of components of road construction machines are presented. The influence of the preparation of a dispersed filler on the properties and structure of the compound has been evaluated. The resistance of the epoxy-sand compounds to the effects of aggressive media (anti-icing materials) was investigated. The values of the friction coefficients of the epoxy-sand compound were determined. It was found that reducing the filler concentration provided the best resistance of epoxy-sand compounds to aggressive media and the best wear resistance of the compound.
