Frequently Asked Questions
Answer: The iridium titanium oxide anode of Xubo Titanium is an IrO₂-Ta₂O₅ system with a minimum coating thickness of 6μm.
Answer: All ASTM Gr1 pure titanium (99.6%) are used. All titanium basket welds are made of argon gas shielded welding (TIG), and the welds are X-ray flaw detection to ensure that there is no risk of intergranular corrosion in 10% H₂SO₄ solution.
A: This anode is specially designed for fluorinated chrome plating solution, supporting CrO₃ concentration of 50-400g/L.It has served an auto parts factory in Guangdong (24h continuous hard chrome plating, 18 months life). Support acid copper sulfate electrolysis (Cu²⁺ 80g/L, H₂SO₄ 180g/L), current efficiency ≥ 96%, case: Jiangxi copper extraction tank project (current density 3000A/㎡, running for 2 years).
Answer: In 5000A/㎡ current density and 60°C chrome plating solution, the promised life ≥ 1.8 years (calculated based on the loss ≤ 0.003g/kg per ton of plating parts).Provide ASTM D1145+ Enterprise Accelerated Aging Report: 5A/cm² constant current test, coating loss rate ≤ 1.2mg/Ah (industry average ≤2.0mg/Ah)
答：采用激光切割钛网，网孔公差为±0.08mm（例如Φ5mm网孔实际尺寸为4.92-5.08mm），以避免卡住小零件。支持全尺寸非标定制：48小时内提供3D图纸反馈方案，并已生产出φ200×1200mm超长圆柱形篮筐（专用于镍钴提取）。
Answer: The titanium/copper joint adopts vacuum explosion welding + milling plane treatment, and the measured contact resistance is **≤0.35mΩ** (industry standard ≤ 0.5mΩ).At 10kA current, the voltage drop of the joint is only 3.5V, which reduces the temperature rise by 15°C compared with ordinary brazing joints.
