Process for producing electrolytic copper foil
At present, roller cathode and insoluble anode are used to produce electrolytic copper foil by continuous method.
1, electrolytic copper. Electrolytic copper or wire return material of the same purity is used as raw material, dissolved in a solution containing copper sulfate, electrolysis is carried out in an electrolytic cell with an insoluble material as anode and a cathode roll with a constant speed rotation at the bottom immersed in the copper sulfate electrolyte as cathode. Copper in the solution is deposited on the surface of the cathode roll to form a copper foil. The thickness of the copper foil is controlled by the cathode current density and the rotation speed of the cathode roll. After the copper foil is transferred out of the liquid surface with the roller, it is continuously peeled from the cathode roller, washed, dried and rolled to produce the original foil.
2, electrochemical reaction as the main process. The process is carried out in three stages: the first stage is to maintain the coarse layer of the dendritic crystal structure composed of copper and copper oxide. A second brass or zinc layer is used as a barrier. In the process of producing printed circuits, the copper foil with a barrier layer can ensure that there is no substrate pollution such as particle migration. In the third stage, in order to prevent oxidation during handling, storage or lamination, the surface of the copper foil is galvanized, nickel, tin and other metals or alloys as an anti-oxidation coating.
3, that is, cut packaging. As some of the cutting and packaging equipment comes with control devices, we do not consider it here. In this way, the entire production process can be divided into four parts: electrolytic copper, surface copper, 10 air conditioning units, and 300,000 air conditioning units.
Electrolytic copper foil production method in the copper dissolution process:
1, principle: The treated copper material is added to the copper dissolving tank, the greater the surface area of the copper material, the better, There should be small gaps between the copper materials, which can increase the reaction area. After adding a certain amount of pure water and sulfuric acid, the compressed air is used to oxidize and combine to produce copper sulfate solution. The chemical formula is 2Cu+2H2SO4+O2=2CuSO4+2H2O. The reaction belongs to solid-liquid, solid-gas and liquid-gas multiphase reactions. The reaction speed is related to the total surface area of the copper material in the tank, the greater the surface area, the faster the reaction speed. Secondly, it is related to the air volume, and the reaction speed is also accelerated as the air volume increases.

Advantage
Our company Titanium Anode For Copper Foil Electrolysis has the following significant characteristics:
1, excellent coating uniformity
From sandblasting to coarsening of titanium plate, optimization of coating formula design, to perfect brushing and heat treatment process, to ensure that the prepared new plate and repaired plate coating has good uniformity and improve the quality of copper foil products.
2, excellent electrocatalytic activity
By increasing the macroscopic and microscopic roughness of titanium matrix, optimizing the coating formulation and preparation process, increasing the catalytic active surface area of the coating and reducing the true current density; At the same time, the resistance of the coating film and the electrochemical reaction resistance are reduced, and the voltage of the electrolytic copper foil production tank is reduced.
3, long service life
By special preparation technology, the forming of IrO2 crystal clusters with electrocatalytic activity is promoted and the crack width of the coating is controlled. It is beneficial to improve electrochemical activity, inhibit the erosion of dissolved oxygen, slow down the formation of TiO2 passivation film, and extend the service life of anode. Under harsh working conditions, the service life of the copper foil anode can reach more than 50000KAh/m2.
4, save power consumption
By electrochemical oxidation technology, TiO2 nanotube array structure was generated to improve the specific surface area and micro-roughness of titanium matrix, enhance the coating bonding force, and reduce the cell voltage.
The initial tank voltage is less than 4V, which is more than 0.15V lower than the anode products in the same industry.
Under 8000A/m2, each single column can save power consumption of about 60,000 KWH/year.
