PROBLEM TO BE SOLVED: To provide a projection material for blasting capable of mirror-finishing or smoothening, without producing satin finished surface-like irregularities, the surface of a workpiece in a very shorter time than in the case of conventional techniques such as polishing or the like by abrasive paper or abrasive cloth, and also provide a method of manufacturing the projection material for blasting. SOLUTION: This projection material for blasting is formed by supporting an abrasive material 12 of 1-50μm on the surfaces of vinyl chloride particles 11 of 10-3,000μm in diameter. The projection material is manufactured by kneading, while heating, polyvinyl chloride particles, an abrasive material, a plasticizer, and a molding assistant 13. COPYRIGHT: (C)2011,JPO&INPIT |
