Application Of Ultrasonic Cleaning Equipment in Galvanized Steel Sheet Cleaning

The core advantages of ultrasonic cleaning equipment in cleaning galvanized steel sheets lie in its comprehensive cleaning of complex structures and low-damage protection of the galvanized layer. Traditional cleaning methods struggle to reach the threads, deep holes, and corners of galvanized steel sheets. Ultrasonic cleaning, however, utilizes the cavitation effect generated by high-frequency vibrations, causing the cleaning solution to form tiny bubbles that rapidly collapse. The resulting impact force penetrates all hard-to-reach areas, thoroughly removing rolling oil, cutting fluid, oxide scale, and passivation solution residues.

Especially in the pre-treatment and post-treatment stages before and after galvanizing, this thorough cleaning effectively prevents defects such as plating bubbles, incomplete plating, and peeling, reducing the defect rate of the plating layer by more than 60%, and improving cleaning efficiency by 8-12 times compared to traditional methods. Simultaneously, precise control of process parameters prevents damage to the galvanized layer, solving the problem of traditional cleaning methods causing blackening and corrosion of the galvanized steel sheet surface.
