7. Product use background and introduction:
Electrolytic copper foil is made by electrolyzing copper sulfate. Due to the strict requirements of the product on quality and performance,th stability of the electrolytic conditions in production is srictly required, and the anode needs to carry a large current. The precious metal-coated titanium electrode has a stable electrode spacing and lower enery 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 recoatng ,in this way,both energy consumption and anode cost will be greatly saved. Due to the above advantages the coated titanium anode is widely used in the manufacturing process of electolytic cooper foil ,from the formation of the copper foil at the front end to the post-treatment of the copper foil.
Under the condition of current density <8000A/m2, the working life of the anode is generally about 8-10 months.
