摘要

PROBLEM TO BE SOLVED: To eliminate subsequent operation required to carry out after blasting against a surface to be treated. SOLUTION: It is possible to produce frozen chemical ice grains as a shot material for blasting as a chemical discharge part 16 is furnished in a cooling tank 11. It is possible to simultaneously apply chemicals on a surface to be treated when it is blasted by using a blasting device. Consequently, it is possible to eliminate coating work of chemicals on the surface which is conventionally done after blasting treatment.
