High-performance titanium anode plate: the core component leading the upgrade of electrolysis process

Product structure and manufacturing process
This anode plate uses high-quality 6mm thick TA1 pure titanium plate as raw material, and is manufactured through multiple processes such as precision bending, shaping, welding and inner arc surface treatment to ensure that it can still maintain structural stability and electrode activity in a long-term electrolysis environment. After special treatment, the inner arc surface is evenly coated with DSA (Dimensionally Stable Anode) coating, which is composed of precious metal oxides and has extremely strong stability and corrosion resistance under high-intensity electrolysis conditions.
The structure of the anode plate adopts a back dry power connection method, which is not only convenient for installation and replacement, but also greatly reduces the complexity of equipment maintenance. From the perspective of installation and maintenance convenience, the dry connection method sets the current introduction part of the anode plate on the back of the anode, and connects it to the busbar through back bolts or conductive hooks, avoiding connection on the front of the anode plate or the electrolyte immersion area. This structure not only makes electrode replacement more convenient and quick, but also allows local repairs or anode replacement without interrupting the operation of the electrolyzer when the equipment is abnormal, greatly reducing the complexity of maintenance and the risk of shutdown, and improving the overall operation efficiency of the factory.
Dry connection avoids direct immersion of the electrical connector in the electrolyte, reducing the risk of contact corrosion and contact resistance. Under long-term operation, the traditional wet structure is prone to problems such as joint corrosion, poor contact, and increased power consumption, while the dry structure achieves good sealing and conductivity in the back power transmission area, extending the stable operation cycle of the electrode system and reducing energy waste caused by joint loss.
In terms of anode functional performance, the DSA coating of the anode plate is one of its performance cores. The DSA coating is composed of precious metal oxides such as iridium, ruthenium, and titanium. It has extremely strong electrochemical stability and catalytic activity, and can maintain stable operation of the anode under high current density and complex electrolyte environments. The DSA coating does not participate in the electrolysis reaction and does not dissolve, which can greatly reduce the risk of contaminating the electrolyte.
Under standard operating conditions, the DSA coating service life of the anode plate can reach ≥30000KAh/㎡, which is equivalent to continuous operation for more than 2300 hours at a current density of 13000A/㎡, or several years of use under medium current density conditions. This ultra-long service life means lower replacement frequency, less downtime and more stable electrolysis efficiency** for enterprises, thereby significantly reducing operating costs.

Main application areas
Titanium anode plates are widely used in the following high-end electrolysis industries:
Electrolytic copper foil manufacturing: As an important process link in the production of lithium battery copper foil, PCB/CCL electronic circuit copper foil, and low-profile copper foil, electrolytic copper foil has extremely high requirements for the stability, current uniformity and corrosion control of the anode material. Titanium anode plates have become the preferred components of copper foil manufacturing equipment due to their extremely high conductivity and insolubility.
Continuous electroplating of steel plates: Titanium anodes can significantly improve the uniformity of the coating, reduce electrode consumption, and improve the overall process consistency in applications such as automatic continuous nickel plating and electrogalvanizing of steel strips.
PCB and hardware electroplating industry: In the hole plating and copper surface plating of PCB multilayer circuit boards, the anode plate can provide a stable electrolytic environment, reduce pinholes and defective rates, and is the core of ensuring the quality of electroplating.
Precious metal electrolytic extraction and non-ferrous metal recycling: Titanium anodes can be used in the electrolytic extraction process of precious metals such as gold, silver, and platinum, as well as the efficient recycling of non-ferrous metals such as cobalt, zinc, and nickel.
Wastewater treatment and organic synthesis: Its excellent corrosion resistance and electrocatalytic properties are also widely used in environmental protection and chemical fields such as industrial wastewater electrolysis treatment and electrocatalytic organic synthesis.

According to different equipment and application requirements, titanium anode plates provide a variety of specifications and models for selection:
Diameter range: φ1500mm, φ2016mm, φ2700mm, φ3000mm, φ3600mm
Width range: 970mm, 1020mm, 1380mm, 1450mm, 1550mm, 1650mm, 1820mm
Users can flexibly customize the appropriate size and shape according to the electrolysis machine model, current density requirements and working environment to meet the multi-level needs from small equipment to large-scale automated production lines.

Titanium anode plates have the following core performance parameters:
Current density bearing capacity: < 13000 A/㎡
Operating temperature range: ≤ 60 ℃
Service life (DSA coating): ≥ 30000 KAh/㎡
Conductive performance: stable output, uniform current distribution
Corrosion resistance: can withstand harsh electrolyte environments such as strong acids and alkalis
These indicators mean that in conventional or complex electrolytic processes, titanium anode plates can show superior characteristics such as durability, stable performance, and economic efficiency.
