The corrosion of the aluminum sheet that I request is friction during operation, not the surface of the container after the passivation of the surface of the container containing sulfuric acid. I'd like to use the evaporating plate, the evaporator fin and so on for the cooling in the quick freezing equipment. The ice of ice making machine is attached to the aluminum plate after anodic oxidation or passivation. When it is peeled off, it will cause friction to the surface of the aluminum plate and block the passivation layer, which will make the aluminum plate easier to corrode.
Directly on the surface coating H2SO4Because the AL and H2SO4 react to produce a dense oxide film that prevents corrosion again, the barrel containing sulfuric acid can be made from AL
Aluminum does not need to be processed to prevent corrosion, and the formation of dense oxide film with oxygen can prevent corrosion
