MMO Ruthenium-Iridium Oxides Coated Titanium Mesh Electrode For Chlor-Alkali Production

Core Structure & Material Advantages

1. Substrate: Titanium Mesh

• Adopts high-purity TA1/TA2 titanium mesh as the base material, with excellent mechanical strength and corrosion resistance to withstand the strong acid/alkali environment and high-temperature electrolysis conditions in chlor-alkali production.
• Mesh structure design ensures large specific surface area, uniform current distribution, and smooth electrolyte flow, effectively reducing energy consumption and improving electrolysis efficiency.

2. Coating: Ruthenium-Iridium Oxide Composite

• The ruthenium-iridium oxide (RuO₂-IrO₂) coating is applied via advanced thermal decomposition technology, with a thickness of 20-50μm, ensuring strong adhesion and wear resistance.
• Ruthenium oxide provides high electrocatalytic activity for chlorine evolution reactions, while iridium oxide enhances coating stability and anti-passivation performance, significantly extending the electrode's service life.

• High Current Efficiency: The ruthenium-iridium coating efficiently catalyzes the chlorine evolution reaction, reducing side reactions and ensuring current efficiency ≥95% in chlor-alkali electrolysis.
• Energy-Saving Advantage: Low electrode polarization resistance, reducing electrolyzer cell voltage by 5-10% compared to traditional electrodes, achieving significant energy savings.
• Long-Term Stability: The composite coating and titanium mesh substrate work synergistically to resist corrosion and wear, minimizing electrode replacement frequency and reducing maintenance costs.

Application Scenarios

• Ion-exchange membrane chlor-alkali electrolyzers (production of caustic soda, chlorine gas, hydrogen gas).
• Diaphragm chlor-alkali electrolysis systems.
• Chlorine generation units in chlor-alkali downstream processes.

Core Value Proposition

• Tailored for Chlor-Alkali: Optimized for the unique working conditions of chlor-alkali production, ensuring reliable operation in high-salt, strong-corrosion environments.
• Cost-Effective: Long service life and energy-saving performance reduce total ownership costs for chlor-alkali plants.
• Eco-Friendly: Inert electrode material, no heavy metal dissolution, avoiding secondary pollution to electrolysis products and the environment.
• Customizable: Supports customization of titanium mesh size, mesh density, and coating composition to match different electrolyzer models and production requirements.
