Titanium Anodes For Ammonia-alkali industry details
Titanium Anodes, also known as DSA-coated titanium electrodes, are core equipment in the ammonia-alkali industry. Our company specializes in providing high-performance titanium anodes for the chlor-alkali industry. These anodes use titanium as the base material and are coated with a precious metal oxide coating, exhibiting excellent conductivity and superior corrosion resistance. They can significantly reduce energy consumption, increase current density, and extend service life.
In the ammonia-alkali industry (especially the chlor-alkali process), titanium anodes are core components. Made of titanium and plated with precious metal oxides such as ruthenium and iridium, titanium anodes possess excellent electrical conductivity and corrosion resistance. Compared to traditional graphite electrodes, titanium anodes significantly reduce energy consumption, increase current density, extend service life by several years, and produce purer chlorine and caustic soda.
Titanium Anodes For Ammonia-alkali industry details
Titanium anodes (also known as DSA anodes, Dimensionally Stable Anodes) are electrode materials with titanium as the substrate and a surface coating of noble metal oxides. In the ammonia-soda industry, titanium anodes are mainly used in the chlor-alkali production process, specifically the electrolysis of brine solutions to produce chlorine, caustic soda, and hydrogen.
Key Technical Advantages
1. Excellent Corrosion Resistance
Titanium anodes exhibit extremely strong corrosion resistance to wet chlorine, sodium chloride solutions, and corrosive media in chlor-alkali production. In a high-temperature, humid chlorine environment, the annual corrosion rate of titanium is only 0.0025 mm, far lower than other materials.
2. Long Service Life: Compared to traditional graphite anodes, titanium anodes have a significantly longer service life: Graphite anodes last only about 8 months; titanium anodes can last 6 years or more, even 3-10 years.
3. Significant Energy Saving: Lower operating voltage, reducing DC power consumption by 10%-20%; higher current density, reaching 2000A/m², more than twice that of graphite anodes; reduces the "bubble shielding effect," improving electrolysis efficiency.
4. Product Quality Improvement: The produced caustic soda is colorless with few organic impurities. The chlorine gas has high purity and contains no CO₂. The high alkali concentration saves on heating steam.
Application Areas: Besides the chlor-alkali industry, titanium anodes are widely used in:
Chlorate production
Hypochlorite production
Perchlorate production
Persulfate electrolysis
Electrolytic organic synthesis
Water treatment
Coating Technology: The coating of titanium anodes mainly uses precious metal oxides such as ruthenium and iridium, which have high electrochemical catalytic performance, effectively reducing the overpotential of chlorine and oxygen evolution reactions and improving reaction efficiency.
Economic and Environmental Benefits: The application of titanium anodes has brought significant economic benefits to the chlor-alkali industry: Approximately 70% of global chlor-alkali production capacity uses titanium anodes. Significant amounts of electricity are saved annually. The use of pollutants such as asphalt and lead is avoided, meeting environmental protection requirements.
Titanium anodes are hailed as a major technological revolution in the chlor-alkali industry. Their application not only improves production efficiency but also promotes the green transformation and technological upgrading of the entire industry.
