Technical Field

[0002] Galvanizing refers to a surface treatment technique that coats metals, alloys, or other materials with a layer of zinc for aesthetic purposes and rust prevention. Hot-dip galvanizing is the primary method used. For steel substrates, zinc coating is an anodic coating, primarily used to prevent corrosion. Its protective properties are highly dependent on the coating thickness. Passivation, dyeing, or coating with a light-protecting agent can significantly enhance the protective and decorative properties of the zinc coating.

Due to the large number of testing positions, the workload is large. At the same time, the manual testing position is not fixed, and the test results may have large errors. Therefore, we propose an adjustable base for hot-dip galvanized zinc coating uniformity testing machine. Utility Model Content
