Why Choose Our MMO Titanium Anode Plate for Chlor-Alkali Industry?
As a key component in chlor-alkali electrolysis (including diaphragm method, ion-exchange membrane method), our MMO Titanium Anode Plate is designed in strict accordance with industrial standards, optimized for the harsh working environment of high temperature, high alkali, and high chlorine concentration. It perfectly addresses the key challenges of chlor-alkali production, bringing tangible benefits to your enterprise:
- Ultra-Long Service Life: Reduce Replacement & Maintenance Costs
Different from traditional graphite anodes (service life only 8 months) and lead anodes (easy to deform and dissolve), our MMO Titanium Anode Plate adopts ASTM B348 standard TA1/TA2 industrial pure titanium (purity ≥99.5%) as the matrix, which can quickly form a dense 5-8nm TiO passivation film in oxidizing media, effectively resisting corrosion of high-concentration chlorine and alkali. The surface is coated with ruthenium-iridium or iridium-Tantalum MMO active coating through thermal decomposition technology, with an annual loss rate of only 1-6mg/A·a, ensuring a service life of more than 6 years in diaphragm method chlor-alkali production—7 times longer than graphite anodes. This greatly reduces the frequency of anode replacement and maintenance, saving labor and material costs for your enterprise. - High Energy Efficiency: Reduce Power Consumption Significantly
The MMO coating of our titanium anode plate has excellent electrocatalytic performance, which can significantly reduce the overpotential of chlorine evolution reaction—140mV lower than graphite anodes at 1A/cm² current density. At the same time, the honeycomb porous structure of the coating (porosity 35%-45%) can quickly eliminate bubbles on the electrode surface, reducing the "bubble shielding effect" and electrode resistance, thus lowering the cell voltage by 15%-20% compared with traditional anodes. In chlor-alkali production, this can reduce DC power consumption by 10%-20%, saving 150-250kWh of electricity per ton of products, which brings considerable energy-saving benefits for large-scale production.
- Stable Performance: Ensure Product Purity & Production Continuity
Our MMO Titanium Anode Plate is an insoluble anode, which only plays a conductive and catalytic role during electrolysis and does not dissolve into the electrolyte, avoiding pollution to the electrolyte and cathode products (caustic soda, chlorine gas) that occurs with lead anodes. This effectively improves the purity of chlorine gas (free of CO₂) and the concentration of caustic soda, reducing subsequent purification costs and improving product quality. In addition, the anode plate has stable dimensions, no deformation during electrolysis, ensuring that the distance between electrodes remains unchanged, the cell voltage is stable, and the continuity of production is guaranteed, avoiding production interruptions caused by anode damage or deformation.
- High Current Density Adaptability: Improve Production Capacity
Compared with traditional graphite anodes (working current density only 8A/dm²), our MMO Titanium Anode Plate can withstand a working current density of up to 17A/dm²—more than double that of graphite anodes. Under the same electrolyzer and plant conditions, this can double the production capacity, greatly improving the single-tank production efficiency and overall labor productivity of your enterprise. It is especially suitable for high-current density electrolysis operations in modern chlor-alkali plants, helping you expand production scale without increasing plant and equipment investment.
