Ultrasonic Coating for Seawater Electrolysis Anode Preparation

Application of Ultrasonic Spraying Machine in the Preparation of Anodes for Seawater Electrolysis

Seawater electrolysis for chlorine production is currently the mainstream, safe, and efficient marine biological anti fouling technology in thermal power plants, nuclear power plants, ships, and coastal industrial scenarios. It can effectively solve problems such as the adhesion and growth of marine organisms, equipment pipeline blockage and corrosion, and ensure the long-term stable operation of coastal industrial equipment. Natural seawater is rich in salt substances such as sodium chloride, with a chloride ion content of up to 15-19g/L. By relying on a diaphragm free electrolytic cell to electrolyze seawater, strong oxidizing and effective chlorine can be generated, which can kill marine larvae and spores and achieve long-term pollution prevention. The entire electrolytic seawater anti fouling system consists of seawater transportation equipment, power distribution equipment, and electrolytic cell group. The seawater electrolysis anode is the core component of the electrolytic cell group, and its performance directly determines the chlorine production efficiency, equipment service life, and enterprise operating costs.

The harsh seawater conditions impose extremely high performance requirements on the electrolytic anode, which is also a long-term technical pain point faced by the industry. The seawater electrolysis anode needs to have electrochemical characteristics of low chlorine evolution potential and high oxygen evolution potential to ensure efficient chlorine production and suppress side reactions; At the same time, it must also withstand high salt and corrosive environments in seawater, with excellent corrosion resistance and structural stability. The anodes prepared by traditional processes generally have problems such as uneven coating, weak catalytic activity, and easy detachment and corrosion. Not only is the electrolysis efficiency low, but it also significantly shortens the service life of the anode. Frequent equipment replacement will significantly increase the operation and maintenance costs of enterprises, restricting the large-scale and efficient application of seawater electrolysis anti fouling systems.

The innovative application of ultrasonic spraying technology has perfectly solved the shortcomings of traditional anode preparation process and become the core process for high-performance seawater electrolysis anode production. The ultrasonic spraying machine relies on the principle of high-frequency ultrasonic vibration to uniformly atomize the ruthenium based catalytic slurry into nanoscale fine droplets. Through targeted and precise deposition, a dense, uniform, and highly adhesive catalytic coating is formed on the surface of the titanium based anode substrate. Compared with traditional spraying and brushing processes, this non-contact spraying method can avoid the problems of substrate damage and uneven coating thickness, greatly improving the utilization rate of catalytic materials and laying a solid foundation for high performance from the process level.

The ruthenium based titanium based metal oxide anode prepared by ultrasonic spraying technology is suitable for the harsh working conditions of seawater electrolysis for chlorine production, and has outstanding comprehensive performance advantages. The uniform and dense nano catalytic coating endows the anode with excellent catalytic activity and selectivity, effectively reducing the chlorine evolution potential and increasing the oxygen evolution potential, accurately enhancing the main chlorine production reaction, suppressing the oxygen evolution side reaction, and greatly improving the efficiency of seawater electrolysis. At the same time, the regular coating structure can effectively block the corrosive medium of seawater, making the anode highly resistant to acid, alkali, and seawater corrosion, completely improving the defects of traditional anodes that are prone to corrosion and failure, and significantly extending the service life of equipment.

In practical industrial applications, the energy-saving and efficiency enhancing advantages of seawater electrolysis anodes prepared by ultrasonic spraying are significant. The stable and efficient electrochemical performance significantly reduces electrolysis energy consumption, and the long service life of the equipment reduces the frequency of anode replacement and equipment maintenance costs, comprehensively reducing the long-term operating expenses of the enterprise. With its technological advantages and high product performance, this spray preparation solution has been widely adapted to various large-scale seawater electrolysis anti fouling systems, providing reliable technical support for marine anti fouling projects in coastal power plants, ships, and industrial facilities.

In summary, ultrasonic spraying technology has reshaped the preparation process of seawater electrolysis anodes, solved the performance shortcomings of traditional anodes, and achieved multiple breakthroughs in high efficiency, long lifespan, and low energy consumption. It is a key core technology for improving the quality, reducing costs, and upgrading the development of seawater electrolysis pollution prevention industry.
