MASS FOR ABRASIVE TOOL MAKING

摘要

FIELD: abrasive materials. SUBSTANCE: mass for making abrasive material has acrylic and methacrylic acids copolymer as strengthening addition and slightly soluble sodium salts (particle size is 2 mm) as pore-forming agent. Invention can be used for making abrasive tool used for polishing plates made of stone. EFFECT: increased wear-resistance and strength of tool, decreased greasing. 1 tbl
