Description:

The profitability of electrolysis/electrodeposition plants is closely related to the performance of cathode plates. By maintaining the cathode plates, their performance cannot be avoided. SMEEC implements a process for cathode maintenance, resulting in a maintained cathode plate with a smooth and level surface, removed impurities, clean contact points, and seamless composite insulation edges. SMEEC's proprietary cathode edge wrapping technology, cathode plate leveling technology, and proprietary service equipment enhance the performance of cathode plates in electrolysis/electrodeposition plants to a new level. Based on the customer's situation, we can provide targeted on-site services.

Detailed explanation of maintenance/repair process:

1、 Cleaning stainless steel cathode plate

Firstly, remove the stainless steel cathode plate from the electrolytic cell, rinse it with clean water, and then clean it with dilute acid solution or alkaline cleaning agent to remove surface dirt and oxide scale. Then, rinse thoroughly with clean water to make the surface dry and free of water stains.

2、 Check the stainless steel cathode plate

After cleaning, it is necessary to inspect the stainless steel cathode plate. The main inspection is to check whether there are scratches, cracks, deformations, and other issues on its surface, as well as whether the contact surface is smooth and free of oxidation. If any problems are found, they need to be fixed.

3、 Repair stainless steel cathode plate

Corresponding repairs are required for the issues identified during the inspection. For example, for surface scratches, a grinding machine can be used for polishing; For deformation or cracks, cold bending or welding repair can be carried out; For oxidation issues, dilute acid or alkaline cleaning agents can be used for cleaning treatment. After repair, it needs to be checked again.

4、 Testing stainless steel cathode plate

After repair, it is necessary to test the stainless steel cathode plate. Mainly test its insulation performance and contact resistance indicators to ensure its normal operation. If the test fails, it needs to be repaired again.

Through the above steps, the repair process of the stainless steel cathode plate is completed. In the production process of electrolytic copper plants, stainless steel cathode plates are very important equipment and require regular maintenance. I hope this article can help readers understand the repair process of stainless steel cathode plates, so as to better carry out equipment maintenance work.
