The production process of electrolytic copper foil is simple. There are three main processes: solution raw foil, surface treatment and product slitting. The production process seems simple, but it is a production process that integrates electronics, machinery and electrochemistry, and is particularly strict with the production environment. Therefore, the industry does not have a set of standard and universal production equipment and technology, and each manufacturer shows its own ingenuity, which is also an important bottleneck affecting the improvement of domestic production capacity and quality. In addition, the different requirements of customers have also resulted in the waste of many intermediate products copper foil in manufacturing. The one-time input-output ratio is even less than 80%, and these copper foils have to be manufactured again, wasting resources.

If the surface stain is caused by environmental problems, the cleaning and improvement of the air conditioning filter system should be strengthened, or the wind speed should be reduced, and the small hairs on the air conditioning filter bag must be completely removed. And the fibers and powders on the polymer materials must be completely removed, which are very easy to cause stains. The air supply pipeline is easy to use plastic material, which does not produce fiber and is easy to clean with water, acid and alkali.

The copper foil industry belongs to the copper processing industry, which processes copper into extremely thin copper strips or sheets by means of rolling, electrolysis and sputtering, and further applies them as industrial raw materials in various downstream products. The thickness of μ Below m, the thickness varies depending on the scene used.

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.

Curing treatment: deposit a layer of dense metal copper in the nodular particle gap of the roughening layer, increase the contact surface between the roughening layer and the wool foil substrate, and reduce the roughness of the roughening layer surface. Microscopically, after rough surface roughening treatment, the foil surface is uneven and undulating greatly, while after curing treatment, the copper foil surface is relatively flat. After curing treatment, although the roughness is reduced, the bonding strength between the treatment layer and the insulating substrate material is improved due to the increased contact area between the roughened layer and the wool foil, which fundamentally eliminates the delamination between the treatment layer and the wool foil.

Copper foil is a key conductive material in lithium ion batteries and printed circuit boards. It is a kind of negative electrolytic material, a thin, continuous metal foil deposited on the substrate of circuit board.
