Pingxiang Preferred Copper Foil Manufacturer for Heat Dissipation
During the production of copper foil, tiny foreign matters are adhered on the surface to form spots with different colors from the surface, which are called stains. Judgment method: use macroscopic inspection to judge whether it is a waste product, a secondary product or a finished product according to the number and area of stains and the impact on product quality.

At the same time of thinning, it is also necessary to improve the tensile strength, elongation and other indicators, otherwise it is easy to cause copper foil fracture, affecting the safety of the battery. Therefore, it is the general trend that the future use will be more light and meet the above indicators.

Copper foil can be divided into many kinds according to different classifications. According to the thickness, it can be divided into: thickness (more than 70 μ m) Regular thickness copper foil (more than 18 μ M but less than 70 μ m) Thin copper foil (more than 12 μ M but less than 18 μ m) Ultra thin copper foil (less than 12 μ m) Etc.

The air supply of general air conditioning has a large impact. For the stains caused by the dirty electrolyte, the filtering of electrolyte should be strengthened. After being transferred from the electrolytic cell, the copper foil must be washed with electrolyte, because the surface of the copper foil is attached with organic matter or other impurities. The water pressure of copper foil washing must have enough pressure and a certain amount of water.

The technical feature of electrolytic copper foil is that various technical conditions in electrolyte and additives must be strictly controlled, so equipment alone is not enough to produce high-performance copper foil; High performance has high requirements for the materials of anode plate and cathode roll in the raw foil equipment, the processing accuracy and consistency of the equipment; In the production process, the concentration of copper and acid in the electrolyte needs to be monitored and adjusted in real time.
