钌铱钛网：电解槽里的 “贵金属铠甲”—— 应用场景与回收价值解析

Group 1 - The core advantage of ruthenium-iridium-titanium mesh lies in its role as a dimensionally stable anode (DSA), making it indispensable in three key industries [2] - In the chlor-alkali industry, ruthenium-iridium-titanium mesh acts as the anode in electrolysis, converting brine into chlorine gas, hydrogen, and caustic soda, with a lifespan of 3-5 years under harsh conditions [4] - In the renewable energy sector, this mesh is crucial for hydrogen production through water electrolysis, significantly reducing energy consumption and contributing to carbon emission reductions [5] Group 2 - The ruthenium-iridium-titanium mesh has three layers of value when recycled: the precious metal coating, the titanium substrate, and environmental benefits from reduced mining impact [7] - The precious metal coating contains approximately 60%-70% iridium and 30%-40% ruthenium, with a market value of 3000 RMB per gram for iridium and 60 RMB per gram for ruthenium [8] - The titanium substrate, with a purity of over 99.5%, can be recycled and reused, with a recovery price of 50-80 RMB per kilogram [9] Group 3 - The pricing for recycling ruthenium-iridium-titanium mesh is determined by four key factors: coating residue, titanium weight and condition, market prices, and processing costs [10] - The coating residue is assessed using spectral detection, which directly influences the value of the old mesh [11] - Market fluctuations, particularly in iridium prices, can significantly impact the recycling price, with historical peaks affecting potential returns [12]
