Titanium is a valve type metal. In the electrolysis process of many industries, titanium as an anode is not conductive. Therefore, when the coating loses its activity, the exposed titanium matrix will not be corroded due to surface passivation, and the titanium matrix can be used repeatedly. When the cell is electrolyzed at the same current density and the economic loss caused by the rise of cell voltage is greater than the cost of anode coating repair and regeneration, it is reasonable to consider repair and recoating. The method of titanium anode repair is to remove the failure coating first, and then recoat it on the bare and clean titanium substrate, which can ensure the electrochemical stability of the repaired titanium anode. The main methods to remove the failure coating are molten salt method, acid boiling method, sulfate electrolysis method and so on. Our company can provide titanium electrode repair and repainting according to the actual needs of customers, so as to save operating costs for customers.
