The importance of galvanized wire surface treatment for pickling

The galvanized wire must be subjected to a pickling process, and the galvanized wire can be subjected to surface treatment after pickling and rust removal. The galvanized wire is not easily rusted after surface treatment and has a long service life.

Galvanized wire production process:

Incoming inspection - pre-cleaning - degreasing - cleaning - pickling - acid - dip solvent - drying - hot dip zinc - removal of zinc - cooling, purification - cleaning - self-inspection - finished product inspection

After being acid-washed, the electric galvanized wire is gradually galvanically plated with metal in the electroplating tank. The production speed is slow, the plating layer is uniform, and the thickness is thin, usually only 3-15 microns, and the appearance is bright. Cold galvanized wire is mainly used in communications equipment, medical equipment and woven nets, brushes, steel cables, strainers, high pressure pipes, construction, handicrafts and other industries.

Hot dip galvanized wire is heated and melted by zinc immersion plating. The production speed is fast, the coating is thick but uneven, and the market allows a minimum thickness of 45 microns and a maximum of 300 microns or more. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. The hot-dip galvanizing can be maintained for several decades in an outdoor environment.
