The reason of galvanized steel strip packing surface pale

The reason of galvanized steel strip packing surface pale. As light steel keel, sink, shutter and bridge are not secondary metal products such as galvanized, so the material in the manufacture of these products is galvanized steel strip. This kind of steel belt is on the basis of the original ordinary steel strip after some processing, such as acid pickling and galvanized process, the process gives the characteristics of the galvanized steel belt is not easy to corrode, was deeply loved by the masses of users. In some cases, we will find the steel strip surface will appear white phenomenon, so what is the reason of this phenomenon? How to solve these problems? The phenomenon of white substance on the surface of the galvanized steel belt is white rust, cause there are many reasons for this: 1, the it environment the presence of large amounts of water vapor in the air, and condensation on the surface of the steel belt, water vapor will react with oxygen in the air, carbon dioxide and other substances, formation of the electrolyte can produce electrochemical corrosion and zinc layer, such a white phenomenon. 2, it may also be because the production is completed, no deposit steel strip completely dry it up, that will also form white. To avoid the happening of this kind of situation, we should avoid to steel with zinc layer contact with the water, in addition to ensure that the location of air flow, a better approach is galvanized layer surface with a layer of oil to prevent white situation.
