As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in the production of advanced electrocatalytic anodes for the chlor-alkali industry. Our Ruthenium-Iridium Coated Titanium Mesh Cylinder Anode is engineered to deliver exceptional performance in the electrolytic production of chlorine and caustic soda. With an annual export value of US$5-10 million and a global market reach spanning North America, Europe, Asia, and beyond, we combine decades of wire mesh expertise with cutting-edge coating technology to provide a reliable, efficient solution for demanding chlor-alkali processes.

This product is specifically designed to replace traditional graphite or dimensionally stable anodes (DSA) in modern chlor-alkali cells. The unique combination of ruthenium and iridium oxides on a titanium substrate ensures low oxygen overpotential, excellent chlorine evolution selectivity, and outstanding corrosion resistance even in harsh acidic and chloride-rich environments. The mesh cylinder structure maximizes surface area while maintaining mechanical strength, facilitating uniform current distribution and efficient gas bubble release.

Below we outline the key features, technical specifications, and benefits that make our anode a top choice for chlor-alkali producers worldwide.

Key Features

High Catalytic Activity: The Ru-Ir mixed metal oxide coating provides excellent electrocatalytic activity for chlorine evolution, reducing energy consumption by 5-15% compared to conventional anodes.
Outstanding Durability: Titanium substrate offers superior mechanical strength and corrosion resistance, while the coating is formulated to withstand the aggressive chlor-alkali environment (high Cl⁻ concentration, pH 1-4, elevated temperatures).
Uniform Current Distribution: Mesh cylinder design ensures even current density across the entire electrode surface, minimizing hot spots and extending service life.
Low Maintenance: The robust coating reduces the need for frequent replacements; typical service life of 3-5 years under normal operating conditions.
Customizable Dimensions: Cylinder diameter, height, and mesh opening can be tailored to fit specific cell designs (e.g., membrane cell, diaphragm cell, or mercury cell).
Enhanced Gas Release: Open mesh structure facilitates rapid escape of chlorine and hydrogen bubbles, preventing gas blinding and improving efficiency.
Environmentally Friendly: Reduces energy consumption and extends operational life, contributing to lower carbon footprint and less waste.

Benefits for Your Chlor-Alkali Process

Energy Efficiency: The low overpotential coating reduces cell voltage, leading to direct electricity savings. In membrane cell operations, savings of up to 10% have been reported.
Longer Operational Life: The robust titanium substrate and stable coating resist degradation from chlorine and acid, ensuring 3-5 years of continuous service, reducing downtime and replacement costs.
Improved Product Purity: High selectivity for chlorine evolution minimizes oxygen formation, resulting in higher purity chlorine gas.
Scalability & Flexibility: Custom dimensions allow seamless integration into existing cell designs, whether membrane, diaphragm, or mercury cells.
Reliable Supply Chain: Our factory in Hengshui, Hebei, China, with over 25 years of manufacturing experience, ensures consistent quality and timely delivery from Tianjin, Qingdao, Shanghai, or Foshan ports.

Frequently Asked Questions

Q: What is the typical lifespan of this anode in chlor-alkali service?
A: Under normal operating conditions (current density 2-4 kA/m², temperature ≤80°C, brine pH 2-4), the anode can last 3-5 years. For more aggressive conditions, thicker coatings can be applied to extend service life.
Q: Can the anode be used in both membrane and diaphragm cells?
A: Yes, the mesh cylinder design is suitable for both membrane and diaphragm cell configurations. We can customize the outer diameter and height to match your cell dimensions.
Q: How does the coating resist chlorine and oxygen evolution?
A: The Ru-Ir mixed oxide coating has high electrochemical stability. The iridium oxide component enhances corrosion resistance, while ruthenium oxide provides high catalytic activity for chlorine evolution. The optimized ratio suppresses oxygen evolution, ensuring high chlorine selectivity.
Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the size and specification. Typically, we accept orders starting from 10 pieces for standard sizes. Custom sizes may require a higher MOQ; please contact us for details.
Q: Do you offer samples for testing?
A: Yes, we can provide small sample anodes for laboratory or pilot-scale testing. The sample cost and shipping are negotiable, and we can adjust the coating composition to match your electrolyte conditions.
Q: Can you provide technical data sheets or performance curves?
A: Yes, we can share typical polarization curves, Tafel plots, and accelerated life test results upon request. Contact our technical team for detailed documentation.
Q: How do you ensure the coating quality and consistency?
A: We use a proprietary thermal decomposition method to apply the coating. Each batch is tested for coating thickness, adhesion, and electrochemical performance using scanning electron microscopy (SEM) and potentiostatic tests. Our quality control complies with internal standards.
Q: What is the lead time for a standard order?
A: For standard sizes, lead time is typically 15-25 working days after order confirmation. For custom sizes, it may be 25-40 working days, depending on complexity.
