Electrolytic copper foil Manufacturing is a technology, capital and talent intensive industry. The production technology of electrolytic copper foil combines electronics, mechanics, electrochemistry and other disciplines, and has strict requirements on the production environment. To produce high-quality products, copper foil manufacturers need to have deep R&D technology reserves, rich production experience and advanced production equipment and technology. The technical characteristics are mainly reflected in the following aspects:

1. Additives and other formulation conditions. Additives determine the performance and use of copper foil to a certain extent. Different additives play different roles in the electrodeposition process, so different types of copper foil need different additives. Due to the variety of additives and their complex relationship, the composition and concentration of additives will affect the performance and productivity of products, so it is difficult to select and prepare additives. Mastering and developing mixed additives should be based on electrochemical and material science research, with effective detection equipment and scientific detection methods, long research and development cycle and high investment.

2. Production process control. The production process of electrolytic copper foil needs the cooperation of all links. In the process of solution preparation, the concentration of copper and acid in the electrolyte changes dynamically. In order to control the concentration within a reasonable range, it is necessary to timely monitor the concentration of copper and acid in the electrolyte and adjust them in real time. In the process of aluminum foil growth, the rotating speed and current of the cathode roll will directly affect the thickness of the copper foil, so it needs to be precisely controlled. In the process of surface treatment, in order to ensure product quality, it is necessary to treat the original foil entering the surface treatment process with different functional characteristics and conduct comprehensive tests. Each production process of copper foil affects each other, and each production node will affect the quality of the final product. Therefore, higher requirements are put forward for the process control level and scientific standardization of enterprise production site management.

3. Equipment control capability. In recent years, due to the continuous development and change of downstream application fields of electrolytic copper foil, the core equipment and operation have not yet formed a unified standard. Main equipment such as copper dissolving tank, diatomite filter, cathode roll foil machine, surface treatment machine, cathode roll grinder, etc. are non-standard equipment, and there are differences in equipment structure and operation technology points among copper foil enterprises. The operation technology of electrolytic copper foil equipment needs years of accumulation. In the process of use and development, we constantly find problems, feed back information, and constantly improve. The additive formula, current density, electrolyte concentration and other production process conditions need to match the level of production line equipment and operators. The development and application of new products, new technologies, and new processes all have a process of running in and continuous improvement.

Therefore, equipment management and control capability directly affects the competitiveness of electrolytic copper foil enterprises. Mature copper foil enterprises can refine the accumulated experience of equipment use, maintenance and upgrading in time by designing and planning the workflow in advance, and integrate it into the production line design, equipment procurement standards and operation specifications, so as to give full play to the ideal efficiency of the production line and make the product quality and yield reach a higher level. However, if electrolytic copper foil enterprises lack experience in equipment control or the ability of operators is insufficient, it will not only lead to low comprehensive efficiency of production equipment, but also have a great impact on the production of electrolytic copper foil products.
