Titanium Anodes for Electrolytic Copper Foil Spraying Machine

Titanium Anodes for Electrolytic Copper Foil Spraying Machine

Against the backdrop of rapid development in industries such as new energy batteries, PCB circuit boards, and electronic components, electrolytic copper foil, as a core basic material, has become an indispensable key component in high-end manufacturing fields due to its excellent conductivity, ductility, and adhesion. Electrolytic copper foil is prepared by electrolyzing copper sulfate solution, and its production process has extremely stringent requirements for quality and performance, especially regarding the stability of electrolysis conditions and the load-bearing capacity of the anode. In the production of electrolytic copper foil, the anode needs to withstand extremely high currents for extended periods. Traditional anodes suffer from drawbacks such as unstable electrode spacing, high energy consumption, and short service life. The emergence of precious metal-coated titanium anodes perfectly solves this problem. As the core equipment for titanium anode preparation and recoating, the Cheersonic ultrasonic spray coating machine, with its core advantages of high precision, high adaptability, and low loss, perfectly meets the spraying needs of titanium anodes for electrolytic copper foil, helping companies achieve both energy and cost savings and promoting the high-quality development of the electrolytic copper foil industry.

The performance of titanium anodes used in electrolytic copper foil directly determines the quality and production efficiency of the electrolytic copper foil, and its coating process has extremely stringent standards. Titanium anodes use industrial pure titanium as the substrate and require a coating of precious metal oxides such as iridium and tantalum to form a dense and uniform catalytic layer. This ensures stable electrode spacing, reduces energy consumption during electrolysis, and improves the anode’s corrosion resistance and service life. The core requirements for coating are concentrated in three main aspects: First, a uniform and dense coating is essential, ensuring precise control over the thickness of the precious metal coating to avoid defects such as pinholes and bubbles, guaranteeing stable electrode spacing, and thus improving the thickness uniformity and surface smoothness of the electrolytic copper foil. Second, strong coating adhesion is crucial, requiring a tight bond with the titanium substrate to ensure the titanium anode does not peel off or fail in the high-current, highly corrosive electrolytic environment, meeting the requirements for long-term stable operation. Third, recoating and reuse are necessary, achieving uniform and precise coating coverage to meet the needs of recoating and reuse after the titanium anode’s lifespan, minimizing anode usage costs. Furthermore, precious metal materials are expensive, and the spraying process must minimize waste to meet the company’s need for cost reduction and efficiency improvement.

Traditional titanium anode spraying processes for electrolytic copper foil (brush coating, air spraying, and dip coating) have many shortcomings and are difficult to adapt to the high-end production requirements. Brush coating is inefficient, with extremely poor coating uniformity, prone to brush marks and missed coatings, leading to unstable titanium anode spacing, increased electrolytic energy consumption, and insufficient coating adhesion, making it prone to peeling and failure, and unable to meet long-term electrolytic requirements. Air spraying relies on high-pressure airflow atomization, resulting in uneven droplet size, easily producing defects such as pinholes and bubbles. High-pressure impact can also cause coating peeling, and the utilization rate of precious metal materials is less than 40%, causing serious waste and significantly increasing production costs. While dip coating can achieve full coverage, it cannot precisely control the coating thickness, easily leading to accumulation and sagging, affecting the stability of the anode spacing, and cannot meet the needs of recoating and reuse, making subsequent processing difficult and increasing process costs.

Cheersonic ultrasonic spraying machine is specifically designed to address the characteristics and spraying challenges of titanium anodes used in electrolytic copper foil production. Utilizing high-frequency atomization technology, it has been specifically optimized to completely break through traditional process bottlenecks and simultaneously meet the core demand for recoating and reusing titanium anodes. The equipment converts industrial frequency electricity into a 40-150kHz high-frequency electrical signal via an ultrasonic generator. This signal is then converted into high-frequency mechanical vibration by a piezoelectric ceramic transducer, causing the precious metal oxide slurry to form uniform droplets of 0.1-10 microns. Guided by a low-pressure carrier gas, these droplets gently deposit onto the titanium anode surface without high-pressure impact, preventing coating peeling and effectively eliminating defects such as pinholes and bubbles. This results in a dense, uniform, and highly adhesive high-quality coating, ensuring stable anode spacing and helping to reduce electrolysis energy consumption. Energy consumption per ton of copper can be significantly reduced, meeting industry energy-saving requirements. The equipment can precisely control the coating thickness, adapting to titanium anode recoating and reuse scenarios. After the titanium anode’s lifespan expires, uniform recoating can be achieved, allowing the titanium substrate to be reused repeatedly and maximizing the value of the titanium anode.

For the coating needs of titanium anodes used in electrolytic copper foil, Cheersonic ultrasonic spraying machines demonstrate four core advantages, helping enterprises reduce costs, increase efficiency, and upgrade quality. First, they offer extreme coating precision, accurately controlling coating thickness with a deviation of ≤±2% and uniformity exceeding 98%, ensuring stable titanium anode spacing, improving the quality of electrolytic copper foil, and avoiding the waste of precious metals caused by excessive coating thickness. Second, they provide strong coating adhesion; low-pressure atomization technology ensures a tight bond between the slurry and the titanium substrate, adapting to high-current, highly corrosive electrolytic environments, extending the service life of titanium anodes, and achieving 40,000 hours of continuous operation in some scenarios. Third, they boast high material utilization, reaching over 95%, significantly reducing the consumption of precious metal materials. Combined with the recoating and reusability of titanium anodes, this doubles the reduction in production costs for enterprises. Fourth, they offer excellent mass production adaptability, supporting automated continuous spraying, seamlessly integrating into large-scale production lines for titanium anodes used in electrolytic copper foil, while also supporting precise control of process parameters to adapt to the spraying and recoating needs of titanium anodes of different specifications, solving the problems of low efficiency, high waste, and poor consistency of traditional processes.

Currently, Cheersonic ultrasonic spraying machines are widely used in the spraying and recoating of titanium anodes for electrolytic copper foil, covering core production areas such as copper foil for new energy batteries and PCBs.
