It is to immerse the rust-removed steel parts in molten zinc liquid at about 500°C to make a zinc layer adhere to the surface of the steel components, thereby achieving the purpose of corrosion protection. It is an effective metal corrosion protection method and is mainly used in metal structural facilities in various industries. During the hot-dip galvanizing process, a large amount of waste gas will be generated. The direct discharge of acidic substances in the waste gas will cause environmental pollution.
