The protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior. Especially after the passivation of galvanized layer, the surface of the oxide layer is more thick and dense, itself has a high oxidation prevention.
On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, at this time, zinc bears the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.
Orchard special electroplating process wire is in the heat of zinc solution immersion plating, production speed, thick but uneven coating, the market allows 1 low thickness of 45 microns, up to 300 microns. It is dark in color, consumes more zinc metal, and forms into the layer with the base metal, and has good corrosion resistance. Hot dip galvanizing can persist for decades in outdoor environment.
Orchard special electroplating process wire shining white, galvanized wire to be sent in a dry and ventilated environment, can not be sent in a wet 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 attack deformation.
