Titanium anode for electrolytic copper foil
Electrolytic copper foil, as one of the fundamental materials in the electronics industry, is mainly used for manufacturing printed circuit boards (PCBs) and copper-clad coatings CCL and other materials are widely used in industries such as home appliances, communication, and computing (3C). In recent years, due to the development of the electronics industry Rapid development, as well as its dense, light, thin, short, and small characteristics, have raised higher and newer requirements for copper foil Manifested in: low (low coarsening), thin (developing towards below 12 microns), high (high physical performance, reliability), and no (surface) Electrolytic copper foil is a highly technical copper processing product with no defects in appearance.
During electrolysis, cations in the electrolyte migrate towards the cathode, and electrons are reduced at the anode. Anion running towards the sun Extremely losing electrons and being oxidized. Connect two electrodes in a copper sulfate solution and apply a direct current. At this point, it will be observed that when the electrodes are connected
On the electrode plate of the source cathode, copper and hydrogen gas are released. The reaction is as follows:
Cathode: Cu2++2e → 2Cu 2H++2e → H2 ↑
Anode: 4OH -+4e → 2H2O+O2 ↑
The copper dissolved from the anode supplements the consumption of copper ions in the electrolyte. By treating the surface of the cathode to a certain extent, the copper layer deposited on the cathode can be peeled off, resulting in a certain thickness of copper skin. Copper foil with certain functions is called copper foil. The titanium anode used in the electrolytic copper foil produced by Denor Company has successfully replaced lead based alloy anodes in the electrolytic copper foil industry. It has the ability to withstand high current densities (8000A/m2), strong service life, and a service life of over 40000 KA.H/m2
