Detailed explanation of how to deal with moisture in galvanized steel

Causes of dampness in galvanized steel
The galvanized layer is an anti-corrosion layer made of zinc covering the surface of steel, which can effectively prevent the steel from being oxidized and making it less likely to rust. However, if the galvanized layer gets wet, rust will occur. There are three main reasons for galvanizing to become damp:
1. The surface galvanized layer has not been properly treated;
2. The storage environment is too humid;
3. The galvanized layer gets damp due to various reasons during use. How to deal with moisture in galvanized steel
1. Oil injection treatment. Use a cleaning solvent to clean the galvanized parts, and after drying, spray an oil spray on the surface to form a protective film to prevent the galvanized layer from contacting the air and causing further oxidation.
2. Comb and remove rust. Use copper wire combs, sandpaper and other tools to comb the damp parts to remove rust and corrosion, and then clean them with clean water. Then, in addition to wiping it with a dry cloth, applying rare earth zinc to the galvanized area can effectively repair the galvanized layer.
3. Heavy galvanizing treatment. Use the zinc steel hot-dip plating process to re-coat a layer of zinc to enhance the corrosion resistance to achieve the purpose of anti-corrosion.
4. Aesthetic reinvention. If the damp parts are serious and affect the appearance, they can be repaired by replacing new parts.

Methods to prevent galvanizing from getting damp
1. Anti-corrosion coatings on metal surfaces such as pipelines and equipment must be constructed with materials of stable quality and not susceptible to moisture;
2. Control the humidity of the storage environment and choose a dry and ventilated place for storage;
3. Avoid being exposed to rain, water or humid environment for a long time, especially avoid being placed in water for a long time.

Conclusion
Moisture in galvanized steel is a common problem. If not dealt with in time, it will seriously affect the service life and even cause equipment damage. Therefore, when using and storing galvanized items, attention should be paid to moisture-proof and waterproof measures. Once moisture problems occur, they need to be dealt with in time. The treatment methods introduced above can effectively repair the galvanized layer and effectively prevent the recurrence of galvanized moisture.
