Why do galvanized coils cause white rust and black rust?
The causes of white rust and black spots are as follows: black spots are formed by further oxidation of white rust.
The main causes of white rust are:
(1) Poor passivation, insufficient or uneven passivation film thickness;
(2) The surface is not oiled or there is residual moisture on the strip surface;
(3) The surface of the strip steel contains moisture during coiling;
(4) The passivation is not completely dried;
(5) Damp or rain during transportation or storage;
(6) The storage time of finished products is too long;
(7) The galvanized sheet is in contact with or stored together with other corrosive media such as acid and alkali.
