Principle of zinc plating

Galvanized coating, also known as cold galvanizing, involves immersing galvanized wire in a solution containing zinc salts after degreasing and acid washing, and then connecting it to the negative pole of an electrolytic device. A zinc plate is placed opposite the galvanized wire and connected to the positive pole of the electrolytic device. When the power supply is turned on, the directed movement of current from the positive pole to the negative pole causes a layer of zinc to deposit on the galvanized wire. Electroplating has a slower production speed, but results in a uniform, thin coating with a shiny appearance, although it is less corrosion-resistant compared to hot-dip galvanized wire。
