Abstract:
     This one-step technology can perform fast and deep chemical etching for steel workpiece. As its etching liquid contains a protective additive that can form a slope by itself, the side surface of workpiece is protected by the protective additive when it is etched on. Thus, the etching of workpiece in etching machine can be automatically completed by one stroke. This technology is suitable for plane, curved surface, and roller.
