BLASTING METHOD AND APPARATUS HAVING ABRASIVE RECOVERY SYSTEM, PROCESSING METHOD OF THIN-FILM SOLAR CELL PANEL, AND THIN-FILM SOLAR CELL PANEL PROCESSED BY THE METHOD

摘要

PURPOSE: A blast processing method and apparatus having the abrasive recovery system, and the processing method and the thin film solar panel processing with this of the thin film solar panel inhale the sound pressure space inside to a pair of suctions. The abrasive within the sound pressure space and cutting piece is collected effectively. CONSTITUTION: The sound pressure space(20) is faced keeping some space. The injection hole(31) of the blast gun(30) is arranged within the sound pressure space. Suctions(21a, 21b) inhale the sound pressure space inside. The opening locates in the floor side of the sound pressure space. Opening comprises the flange type push plate. The rectifying plate(24) locates in both sides of the injection hole of the blast gun. The rectifying plate prevents from the abrasive being attached to the surface of product.
