Description

Technical Field

[0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetic purposes and to prevent rust. The main method used is hot-dip galvanizing. Because zinc is an active metal, if the zinc plating is not well post-treated, the coating will quickly darken and white corrosion products will appear one after another. In order to reduce the chemical activity of zinc, it is often passivated to form a chromate conversion film on the surface of the zinc layer to achieve an anti-corrosion effect.

[0003] In the prior art with the publication (announcement) number: CN218842329U, a passivation tank for galvanizing processing is disclosed, which points out the problem that "the current galvanizing passivation tank will cause the passivation liquid to precipitate when working for a long time, thereby causing the passivation liquid to be uneven, affecting the passivation effect of the workpiece, being unfavorable for the galvanizing processing of the workpiece, and reducing the quality of the workpiece", and solves the above problem.

[0004] However, in the above-mentioned prior art, the placing screen frame is placed in a passivation tank and guided by a slide rod, which makes it impossible to remove the placing screen frame from the passivation tank.
