COMPOSITION FOR MAKING ROTOR WHEELS OF ELECTRIC SUBMERSIBLE CENTRIFUGAL PUMPS

摘要

FIELD: chemistry. ^ SUBSTANCE: composition is a mixture of filler - discrete basalt fibre with fibre diametre of 9-12 mcm and length of up to 1000 mcm with binder - epoxyvinylether resin EVS-9133. Concentration of said filler in the mixture is 30-70 wt %. ^ EFFECT: high temperature resistance of material hardened with disclosed composition, high wear resistance in a liquid medium containing abrasive material and in dry friction conditions, chemical resistance during operation in aggressive media, reduced probability of scaling on the surface, simple formulation, cheap preparation and wide range of compositions. ^ 1 tbl, 7 ex
