Application Principle of Collagen Peptide in Copper Foil Industry

The introduction of Bovine Bone Collagen Peptide is an important way of performance regulation in the preparation process of electrolytic copper foil. By introducing an appropriate amount of gelatin or collagen additives into the electrolyte, when the additive content in the electrolyte is about 0.02%~0.05%, it can be improved to varying degrees. Increasing the cathodic polarization and inhibiting the abnormal growth of metal is beneficial to obtain dense cathode deposits and improve the elasticity, strength, hardness and smoothness of copper foil. The addition amount of collagen additive must be appropriate, if the addition amount is too much, not only the voltage of the tank will increase, but also streaks will appear on the rough surface of the raw foil, and the copper foil will become brittle.

Purpose of Adding Collagen Peptide in Copper Foil Industry

The purpose of adding gelatin and collagen to the electrolyte is to act as a leveling agent to improve the surface roughness of the electrolytic copper foil. (Mechanism: On a microscopically rough surface, the effective thickness of the diffusion layer at the valley is greater than that at the peak, and the diffusion rate of the leveling agent (molecules or ions) into the valley is smaller than that at the peak, so the concentration of the leveling agent at the peak Greater than the concentration of the leveling agent at the valley, the inhibitory effect on Cu2+ discharge at the peak is greater than that at the valley, so as to achieve the leveling effect.)

1. The principle of dissolving copper:

Liquidation (production of copper sulfate solution) is carried out in the liquidation tank through the chemical reaction of sulfur and copper materials under heating conditions. , and perform multi-channel filtration to generate copper sulfate solution. → The special pump drives into the electrolyte storage tank.

4，Raw foil manufacturing

When the copper sulfate electrolyte enters the anode tank, an electric field is formed between the positive and negative electrodes. Under the action of an electric field, copper ions migrate and deposit on the surface of the cathode roll, depositing a very thin copper. Peel off from the cathode roll and wind up on another roll. In this way, the electrolyte is continuously circulated.

The principle of wool foil electrolysis: the main components of copper sulfate aqueous solution are copper ions, hydrogen ions and a small amount of other metal ions, hydroxide ions, sulfate ions and other anions. Under the action of direct current, cations move to the cathode, and anions move to the anode. The anode generally uses an insoluble anode (lead-silver alloy or coated titanium plate, etc.). Copper ions are reduced to copper, which crystallizes on the cathode roll.

The purpose of adding gelatin and collagen to the electrolyte is to act as a leveling agent to improve the surface roughness of the electrolytic copper foil. (Mechanism: On a microscopically rough surface, the effective thickness of the diffusion layer at the valley is greater than that at the peak, and the diffusion rate of the leveling agent (molecules or ions) into the valley is smaller than that at the peak, so the concentration of the leveling agent at the peak Greater than the concentration of the leveling agent at the valley, the inhibitory effect on Cu2+ discharge at the peak is greater than that at the valley, so as to achieve the leveling effect.)
