In the hydrometallurgical industry, processes such as nickel electrowinning, copper electrowinning, and cobalt electrowinning.etc, which typically use titanium plates as their cathode plates. Titanium cathode plate, due to its good corrosion resistance and light weight, can effectively improve the service life of the cathode plate and reduce the working load during the stripping of the starting sheet. So titanium cathode plate is the preferred cathode material in electrolysis processes.
Normally titanium cathode plate consists of a titanium clad copper rod and a titanium cathode plate welded together. Titanium clad copper rod is a copper rod wrapped with a titanium layer, as the overall titanium layer on the outside of the titanium clad copper rod, which can effectively prevent corrosion of the internal copper rod in acidic atmospheres; At the same time, the titanium layer enhances the rigidity and suspension strength of the copper rod, making the titanium cathode plate less prone to deformation and extending its service life. The exposed copper rod is used to make the copper inside serve as a conductive carrier.
1. The titanium cathode plate has good chemical stability. In various acid and alkali media, it has good corrosion resistance, and in copper electrolyte, the corrosion rate is only 0.011 millimeters per year.
2. The surface of the titanium cathode plate forms a continuous, dense, and uniform oxide film, which is equivalent to a good and durable separating agent. The use of titanium cathode plates saves separating agents and eliminates the pre-treatment process of cathode plates.
3. Due to the difference in thermal expansion coefficient, copper and titanium plates are easily separated and can be torn by hand.
4. The density of titanium cathode plate is small, and its weight is only half that of copper, greatly reducing labor intensity and improving production efficiency.
5. It can be used in high current density to improve the utilization rate of electrolytic cells and expand production capacity.
