Product use background and introduction:
Electrolytic copper foil is copper foil produced by electrolytic copper sulfate. Due to the strict quality and performance requirements of the product, the stability of the electrolytic conditions in production is strict, and the anode must carry a large current. The precious metal-coated titanium electrode has a stable pole pitch and has lower energy consumption. At the same time, the titanium anode has the advantage of repeated use after recoating. After the life of the titanium anode reaches the end, it can be reused by recoating. In this way, both in terms of energy consumption and anode cost will be greatly saved. Because of its above advantages, coated titanium anodes are widely used in the manufacturing process of electrolytic copper foil, from the formation of copper foil at the front end to the post-treatment of copper foil.
Under the condition of current density <8000A / m2, the working life of the anode is generally about 8-10 months.
