钌铱钛网：从电解槽核心到资源循环的价值跃迁

Group 1 - Ruthenium-iridium-titanium mesh is penetrating the new energy and chemical industries, acting as an "industrial vitamin" due to its exceptional corrosion resistance and conductivity [1] - In a domestic chlor-alkali enterprise, the ruthenium-iridium-titanium mesh anode has a lifespan of 8 years, which is 300% longer than traditional graphite electrodes, and reduces the electricity consumption for producing caustic soda by 15% [1] - The recycling market is experiencing a significant value transformation, with the price of used mesh materials showing a notable gradient, reaching 820 RMB/kg for materials containing 15g/m² of ruthenium and 5g/m² of iridium [1] Group 2 - Traditional pyrometallurgical recovery has a recovery rate of only 70%, while a leading company has improved ruthenium recovery to 92% and iridium purity to 99.95% using a "microwave digestion-ion exchange" technology [3] - The demand for ruthenium-based catalysts is expected to reach 220 tons/year by 2030 due to the global hydrogen energy strategy, creating a tight supply-demand balance that increases the recycling value of used ruthenium-iridium-titanium mesh [3] - The comprehensive recovery rate of ruthenium and iridium from recycled mesh materials has increased by 18 percentage points from 2020, directly boosting the gross profit margin of a recycling company to over 35% [3] Group 3 - The dual revolution in materials and resources is constructing a closed-loop value chain, where front-end applications drive industry upgrades and back-end recycling ensures resource security [6] - Establishing a graded management system for waste mesh materials and utilizing rapid detection technologies can maximize recycling value for waste-producing enterprises [6] - Advanced technologies like supercritical CO₂ extraction are key for recyclers to break through industry homogenization in the context of increasingly scarce precious metal resources [6]
