Currently, the steel with the steel plate containing magnesium, the zinc coat of aluminium as the corrosion resistance excellent to rust, are exposed to general ring
Border, when being especially an exposure in wet atmosphere, the phenomenon that surface can generate white rust and get rusty.In addition, due to being included in coating
In magnesium and aluminium and oxygen affinity it is better than zinc, therefore, if being incorporated into the hypoxgia of zinc, blacking phenomenon will be easy to happen.Make
For the link of antirust treatment, organic film is formed after industrially generally pre-processing using chromate to metal surface.However, chromium
The problems such as safety of the heavy metal-polluted water process of hydrochlorate and staff, is paid more and more attention.In addition, in washing water and giving up
The solution containing 6 valence chromium generated in water etc. needs to be handled by specially treated process, and subsequent expense is excessively high., therefore need
It develops and chromium-free anti-corrosion uses surface treating agent.
