WATER-BASED COMPOSITION FOR ABRASIVE SLURRY, PREPARATION METHODS AND USE THEREOF

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to liquid compositions used to prepare abrasive slurries for loose abrasive mechanical processing. The composition contains 40-50 vol % polyethylene glycol and 50-60 vol. % water. The composition can contain a viscosity modifier which provides viscosity ranging from 40 to 100 cP, and a viscosity activator selected from triethanolamine and aminoborate. The invention also discloses a method of preparing a liquid composition for use in back-and-forth cutting with a wire saw. The liquid composition is obtained by mixing components of the composition. Abrasive particles selected from silicon carbide, diamond and boron carbide are uniformly dispersed inside the composition. A working slurry with concentration of the solid phase equal to 20-28% of the volume of the composition is obtained. Water is added to the working slurry in order to change viscosity to the one required for cutting.;EFFECT: invention enables to obtain low-viscosity abrasive slurries which prevent settling down of the solid phase and reduce destruction of plates when cutting with a wire saw.;20 cl, 1 tbl, 2 dwg, 3 ex
