Zhenjiang Preferred Battery Copper Foil Price
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.

The surface of the copper foil shall be smooth and clean without obvious wrinkles, oxidation spots, scratches, pitting, pits and stains. The porosity of 305g/m2 and above shall not exceed 8 penetration points within the area of 300ram × 300mm; The total area of pores on an area of 0.5m2 shall not exceed the circular area with a diameter of 0.125mm.

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.

Excellent tensile strength and elongation High tensile strength and elongation under normal conditions can improve processing ability, enhance rigidity and avoid wrinkles to improve production qualification rate. High temperature extensibility (THE) copper foil and high tensile strength copper foil at high temperature can improve the thermal stability of printed boards and avoid deformation and warpage.

Copper foil is an indispensable raw material for making printed circuit board (PCB), copper clad plate (CCL) and lithium-ion battery. For industrial use, it can be divided into calendered copper foil and two categories according to its manufacturing process. Electrolytic copper foil is made by electrolysis of copper based on electrochemical principle. The internal structure of raw foil is vertical acicular crystal structure, and its production cost is relatively low.
