PROJECTION MATERIAL FOR BLAST WORK AND BLASTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a projection material for blast work and a blasting method by which a surface of a workpiece can be mirrored or smoothened in a very short period of time without generating a satin-finished-like unevenness on the surface of the workpiece comparing with conventional techniques such as polishing with a polishing paper or a polishing cloth.;SOLUTION: In the blasting method, the projection material is projected to the surface of the workpiece by a blasting apparatus, wherein the projection material is formed by bonding polishing particles one another, and the each polishing particle is formed with abrasive materials having a diameter of 0.1-300 μm supported on a surface of a thermoplastic resin particle having a diameter of 1-500 μm.;COPYRIGHT: (C)2011,JPO&INPIT
