Regarding the maintenance of titanium anode, that is, if it is used continuously, there is basically no need for regular cleaning. Instead, it is the long downtime that needs attention. Once the equipment is shut down for a long time, it is necessary to clean the surface of the titanium anode, and usually only need to use pure water to clean the residual electroplating solution on the surface.

The key to cleaning is to clean the two substances of sulfuric acid and copper sulfate on the surface of titanium anode. This is because sulfuric acid in the plating solution will adhere to the surface of the titanium anode coating, and with evaporation, the concentration of sulfuric acid will be significantly increased, resulting in the enhancement of sulfuric acid corrosion. At the same time, the copper sulfate remaining on the surface of the titanium anode will also crystallize out. The copper sulfate in the electroplating solution will go deep into the micropores of the titanium anode surface coating and crystallize out, which will cause certain damage to the coating structure.

Another issue that needs to be reminded is that before the equipment is put into use or during major maintenance, avoid using a strong alkali solution to clean the titanium anode. Strong alkali solution not only has a certain corrosion effect on the coating but also on the titanium substrate, which is easy to cause the peeling of the coating and lead to the premature failure of the life of the titanium anode.
