Description

Technical Field

[0001] The utility model relates to the technical field of galvanized sheet processing, in particular to a chromium-free passivation device for galvanized sheets. Background Art

[0002] In the machinery manufacturing industry, various metal plates and parts are often processed. In order to slow down the corrosion rate of the metal, most of the various metal plates and parts are passivated to improve the corrosion resistance of the metal. The existing galvanized chromium-free plate passivation device passivates the surface of the galvanized chromium-free plate. During the passivation process, it is difficult to ensure that both sides of the galvanized plate are in full contact with the passivation liquid, and the passivation effect of the galvanized chromium-free plate is not good enough. Therefore, it is necessary to provide a galvanized chromium-free plate passivation device that can passivate the galvanized chromium-free plate in all directions and improve the passivation quality.
