Reasons for the whitening of galvanized packaging steel strip

The reason for the whitening of the galvanized packaging steel strip.
　　 Metal products such as light steel keels, sinks, rolling doors and bridges are all non-galvanized, so the materials used to manufacture these products are galvanized steel strips. This kind of steel strip is processed on the basis of the original ordinary steel strip, such as pickling, galvanizing and other processes. These processes endow the galvanized steel strip with the characteristics of being resistant to corrosion and are deeply loved by the majority of users. Sometimes, we will find that the surface of these steel strips will appear white. Then what is the reason for this phenomenon? How to solve these problems?
　　 The whitish material on the surface of the galvanized steel strip is actually white rust. There are many reasons for this:
　　 1. There is a lot of water vapor in the ambient air where it is located, and the water vapor condensed on the surface of the steel strip will react with oxygen, carbon dioxide and other substances in the air, and the formed electrolyte will cause electrochemical corrosion with the zinc layer. There was a whitish phenomenon.
　　2, it may also be because after the production is completed, the steel strip is stored before it is completely dry, which will also cause whitening.
　　 To avoid this situation, we must try to avoid the contact of the zinc layer of the steel strip with moisture, and ensure that the air in the storage location is unobstructed. A better way is to apply a layer of oil on the surface of the galvanized layer to prevent The occurrence of whitishness.
