Recently, a non-abrasive projection material made of soft synthetic resin such as plastic is mainly used as the blasting material. The main reason for the use of such non-abrasive projection materials is that the burrs, rough surfaces, and contaminants present on the outside of the blasting object can be removed more quickly and efficiently with little or no surface damage. Because there is. In addition, it is easy to recycle and can be blasted even at low pressure, which is economical and safe.

However, the blasting material made of such a conventional non-abrasive projection material is light and flexible, so that the blasting material is frequently attached to depressions of the blasting object even after the blasting process, which may cause product defects in the next process. Although necessary, since the size is small and has an inconspicuous color, it is not easy to identify, which causes problems in the overall product production process and causes product defects.

Therefore, the technical problem to be solved by the present invention is to solve the above problems to provide a blasting material that can be easily separated and removed from the blasting object by significantly improving the identification of the blasting material attached to the blasting object after the blasting process It is done.
