The quality of industrial cabinet locks is directly related to the safety of materials used in the portal, so it is very important to choose the industrial cabinet locks without rust. So how to rust the locks of industrial cabinets when using locks in peacetime?
In distinguishing whether the metal in industrial cabinet lock is corroded or not, it is necessary to distinguish the metal rust from the surface defect caused by metal processing from the damage caused by daily insertion. Generally, it can be completely distinguished by magnifying glass observation.
Because most of the metal rusts are loose and porous solid substances attached to the metal surface of industrial cabinet locks, the combination with the base metal is not firm. Under the action of external force, the modifier will peel off the metal body, which is the main principle of physical rust removal. External force can be exerted by sand blasting, shot blasting, grinding and polishing. The rust of metal is mostly composed of metal oxides or hydroxides, so it is easy to react with acid.
The precipitation of hydrogen can reduce iron oxide and magnetic iron oxide in the rust layer of industrial cabinet lock to ferrous oxide which is easy to react with acid. It is conducive to the melting of oxides. It can also accelerate the exfoliation of insoluble oxide skin and the removal of oxides. However, hydrogen may also be absorbed by matrix metals and cause hydrogen embrittlement.
