Description
Technical Field
The invention belongs to the technical field of passivating agent treatment, and particularly relates to passivating agent regeneration and reuse equipment and a method.
Background
Passivation refers to a process of passivating a metal surface by oxidizing the metal with a strong oxidant or an electrochemical method to make the surface inactive, and is a method of converting the metal surface into a state which is not easily oxidized to slow down the corrosion rate of the metal. In the current electroplating zinc plating process, an important process is a passivation process after zinc plating, in the passivation process, a galvanized part is soaked into a groove provided with a concentrated passivator, but ions in the passivator groove change along with the continuous passivation of the part, wherein zinc ions and iron ions are continuously increased because zinc and iron on the part are partially dissolved by the acidic passivator. When the zinc and iron ions rise to a certain level, the bath passivator is unusable and a bath is reconfigured to be emptied.
In actual production, the passivator is treated by direct treatment, recovery or discharge, and cannot be recycled, so that great waste is caused. At present, the period of passivating agent replacement of each production enterprise is generally about one month, and the production cost is overhigh.
