Zinc

is easily soluble in acid and soluble in alkali, so it is called an amphoteric

metal. Zinc hardly changes in dry air. In moist air, a dense zinc carbonate

film is formed on the zinc surface. In the atmosphere containing sulfur

dioxide, hydrogen sulfide and marine, the corrosion resistance of zinc is

poor, especially in the atmosphere containing high temperature and high

humidity containing organic acid, the zinc coating is easily corroded. The

standard electrode potential of zinc is -0.76V. For steel substrates, zinc

coating is an anodic coating. It is mainly used to prevent corrosion of steel.

Its protective performance has a great relationship with the thickness of

the coating. After passivation, dyeing or coating of the photoresist, the zinc

coating can significantly improve its protection and decorative properties.
