Why is galvanized wire not easy to rust? The protection of the zinc layer on the iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, its oxide film is not as loose and dense as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc inside. Especially after passivation galvanized layer, the surface oxidation layer is more thick and dense, and it has a high oxidation resistance.
On the other hand, when the surface of the galvanized layer is damaged, exposing the internal iron matrix, because zinc is more active than iron, then zinc assumes the role of sacrificing zinc anode, zinc will be oxidized before iron, thus protecting the iron layer from damage.
Orchard special electroplating process iron wire is dipped in the heated melting zinc solution, the production speed is fast, the coating is thick but not uniform, the market allows a low thickness of 45 microns, up to 300 microns or more. The color is dark, the consumption of zinc metal is much, the entry layer is formed with the base metal, the corrosion resistance is good, and the hot dip galvanizing can persist for decades in the outdoor environment.
Orchard special electroplating process wire shiny white, galvanized wire should be placed in a dry and ventilated environment, can not be placed in a humid environment. Galvanized wire can not be put together with acid and alkaline substances to prevent chemical reactions and corrosion of galvanized wire. Galvanized wire must also be placed flat to prevent zigzag deformation.
