What causes galvanized steel to appear whitish?
If there is a layer of condensed water on the surface of the zinc coating, it will turn into a corrosive aqueous solution after interacting with chemical gases such as oxygen, carbon dioxide, hydrocarbons, sulfur dioxide, smoke, dust, etc., and then adhere to the surface of the zinc coating to form Electrolytes. The electrolyte electrochemically corrodes the zinc layer with poor chemical stability, resulting in a powdery corrosion product - white rust.
The main reasons for corrosion of the zinc layer indoors are: ① High indoor air humidity; ② The finished product is stored in the warehouse without drying; ③ There is a layer of water film condensation on the surface of the zinc layer. When the water content in the air reaches 60% or is in the range of 85~95%, and the PH value is less than 6, the corrosion reaction will be more intense.
When the water temperature reaches about 70°C, the corrosion rate of the zinc layer is faster. Methods to prevent white rust include: ① When stacking zinc plates, there must be no condensation on the surface; ② Air circulation should be maintained in the warehouse, and the relative humidity of the air should not be 60% or Between 85~95%; ③ There should be no harmful gases and excessive dust when stacking zinc plates; ④ The surface of the galvanized layer should be oiled and passivated.
