G1300-1-4 Development of Composite Abrasive for Glass Polishing

Abstract

Composite abrasives have been developed for improving the dispersibility and cleanability of the conventional glass polishing that uses cerium oxide abrasives. The composite abrasives are fabricated by adhering cerium oxide abrasives to the surface of polymer particles using a hybrid mixer. In this report, the effect of the shape and specific gravity of polymer particles on the polishing characteristics are investigated using aspherical poly-urethane particles and SiO2 mixed poly-urethane particles. The "golf ball-shaped" particles are found to be most effective for glass polishing. The removal rate increases with increasing the specific gravity of polymer particles.
