Customized Services

To meet the needs of different industries, Wstitanium’s professional technical team can customize coating formulations and anode morphologies based on your provided parameters, including electrolyte composition, current density, temperature, and pressure. For example, we develop specialized tantalum-doped coatings for high-fluorine environments, increasing the fluorine concentration tolerance to over 50ppm. Coating materials are a key factor in determining the performance of MMO titanium anodes. Based on different electrochemical reaction characteristics, Wstitanium has developed three types of coating systems, covering over 95% of industrial applications:

1. Ruthenium Coatings

Based on RuO₂-IrO₂ and RuO₂-TiO₂ composite oxides, they focus on optimizing chlorine extraction performance. The chlorine evolution overpotential is ≤1.36V (vs. SHE), making it particularly suitable for high-chloride environments. This coating remains stable in Cl⁻ concentrations above 300g/L, with an annual corrosion rate of less than 0.01mm. It is a specialized coating system for the chlor-alkali industry. Field tests at a large chlor-alkali plant have shown that the use of this coated anode increased chlorine purity from 99.5% to 99.98%, with a current efficiency of 94%, achieving mercury-free production.

2. Iridium Coating

Mainly includes two mixed oxide formulations: IrO₂-Ta₂O₅ and IrO₂-SnO₂. These coatings focus on oxygen evolution reaction efficiency. The oxygen evolution potential can be controlled below 1.40V, with a polarizability of ≤40mV. Among them, the IrO₂-Ta₂O₅ coating offers exceptional corrosion resistance and stable operation within a pH range of 0-14. It is suitable for sulfate electrolysis and high-potential electrolytic hydrogen production, with a service life exceeding five years. The IrO₂-SnO₂ coating excels in hydrometallurgy, particularly suited for the electrolytic extraction of metals such as copper and zinc.

3. Special Functional Coatings

Two types of specialized coatings have been developed for high-end precision applications: a platinum-group metal modified layer, doped with nano-sized platinum particles, achieves coating thickness uniformity of ±3%, meeting the precision electroplating requirements of 5G communication devices and high-end watches. The PbO₂-MnO₂-doped coating is specifically designed for treating refractory organic matter. In dyeing and printing wastewater treatment, it can achieve a COD removal rate of 85% and a color removal rate exceeding 90%. Furthermore, for aluminum foil electroplating, the custom-developed iridium-tantalum coating can operate stably in ammonium adipate and ammonium citrate media for 9-18 months, achieving a weight loss of ≤0.006 mg/s⁻¹.

MMO Titanium Anode Shapes

Wstitanium offers six types of MMO titanium anodes, tailored to the equipment structure and space requirements of various industries. Full-size customization is available:

1. Mesh Anode

Woven from 3×50mm titanium ribbon, this anode features a mesh density of 50-200 mesh and a porosity of 60%-80%. Its surface area is 3-5 times higher than that of flat electrodes, making it particularly suitable for applications requiring efficient mass transfer. Standard sizes range from 500×1000mm to 2000×3000mm, and it can be spliced ​​to suit the size of the electrolytic cell. For tank corrosion protection, mesh anodes laid at 3m intervals can increase edge protection coverage from 85% to 98%.

2. Tubular Anodes

Outer diameter specifications are 20-100mm, standard lengths are 1-3 meters, and can be customized up to 6 meters. Wall thicknesses are 3-5mm to ensure strength for deep well installation. Multiple anodes can be connected in series to form anode strings with dimensions of 219×4000mm, 219×6000mm, and other sizes, providing a protection radius of up to 150m.

3. Plate Anodes

Using 0.5-3mm thick Gr1-grade titanium plates, the surface is sandblasted to enhance coating adhesion. Standard sizes are 300×500mm and 500×800mm, and customizable cutting is possible. In the electroplating industry, plate anodes provide uniform current distribution, increasing the electroplating yield of mobile phone midframes from 82% to 97%.

4. Wire and Flexible Anodes

Wire anodes have a maximum diameter of 3mm. Flexible anodes utilize an 8mm PTFE encapsulation with a minimum bend radius of 50mm, allowing for flexible routing along equipment contours. In the cargo hold area of ​​LNG carriers, flexible anode cables achieve a splash zone protection potential compliance rate exceeding 99%, increasing installation efficiency threefold compared to traditional plate anodes. Their unique connection design ensures that a single point breakage does not affect overall performance.

5. Rod Anodes

Diameters range from 8-20mm, and lengths range from 500-2000mm. They are primarily used in small electrolysis equipment and laboratory devices. In small water treatment equipment, rod anodes enable precise localized electrolysis and, when combined with a three-dimensional electrode system, improve pollutant removal efficiency.

6. Wire Anodes

Diameters range from 1-3mm. Made using a precision wire drawing process, they are suitable for high-density electrochemical devices. They are widely used in micro-electroplating and medical devices, enabling nanoscale coating control.
