The Lead Dioxide Anode (also known as Lead Dioxide Metal Anode) is a high-efficiency electrode product specifically engineered for strong acid environments and high-demand electrochemical scenarios. As a high-quality alternative to platinized anodes, it integrates exceptional performance, superior stability, and cost-effectiveness, widely adapting to core needs across multiple fields such as industrial production and environmental protection treatment.
Core Product Features
- Premium Substrate & Coating Technology: Adopts Grade 1 (Gr1) pure titanium as the substrate, with chemical composition strictly complying with industrial standards (N ≤ 0.03%, C ≤ 0.08%, H ≤ 0.015%, Fe ≤ 0.20%, O ≤ 0.18%, Ti as balance), delivering excellent corrosion resistance and mechanical strength. The surface is coated with high-purity lead dioxide (PbO₂) coating, boasting industry-leading uniformity and an oxygen evolution potential of <1.75V, which effectively reduces electrochemical reaction energy consumption and extends the electrode's service life.
- Adaptability to Harsh Operating Environments: Specifically designed for chlorine-free (Cl⁻-free), pH=7, and high-COD medium environments. It can withstand an operating temperature of 40-60°C, support a current density of ≤5000 A/m², and adapt to polarity reversal requirements of 2-4 hours. Exhibits outstanding anti-wear performance in strong acid systems, preventing electrode failure that may impact production efficiency.
- Cost-Effective Advantage: Compared with traditional platinized anodes, it significantly reduces procurement costs while maintaining comparable core electrochemical performance. Additionally, it simplifies post-maintenance processes, providing strong support for enterprises to achieve cost reduction and efficiency improvement.
Core Application Scenarios
- Electroplating & Surface Treatment: Suitable for conventional chromium plating, hard chromium plating processes in strong acid systems, as well as metal surface chromate treatment. Ensures uniform and dense coatings, enhancing the corrosion resistance and wear resistance of workpieces.
- Chemical Synthesis: Applicable to the electrolytic production of chemical products such as chromic acid, perchlorates, and periodates. Features high reaction conversion rate and stable product purity, meeting the stringent requirements of the fine chemical industry.
- Organic Sewage Treatment: Targets high-COD organic wastewater, efficiently degrading pollutants through electrochemical oxidation technology without the need for additional chemical agents. Environmentally friendly with up-to-standard treatment effects, adapting to industrial wastewater and special sewage purification scenarios.
- Nonferrous Metal Recovery: Enables the electrolytic extraction and recovery of nonferrous metals such as copper, nickel, and cobalt in strong acid solutions. Ensures high metal recovery rate and purity, supporting resource recycling and sustainable development in the metallurgical industry.
