Because iron sheets are prone to chemical reactions in various environments, they cause corrosion and rust. Zinc hardly changes in dry air. In moist air, a dense zinc carbonate film is formed on the surface of zinc. The spiral duct is mainly plated with zinc on the iron sheet of the wind pipe, which plays a protective role on the iron sheet. Zinc coating is passivated, dyed or coated with light retaining agent, which can significantly improve its protective and decorative properties.
