2. Fluorine and chlorine resistance improved by 200%. Corrosion resistance in electrolytes: Cl-≤500mg/L; F-≤300mg/L.
3. The electric current efficiency can be increased by 5% ~ 10%.
4. Cell voltage can be reduced by 0.05V ~ 0.10V.
5. The current density can be increased to 350-500A/m² during the copper or zinc electrowinning process.
6. The copper production capacity is increased by 3% ~ 10%.
7. The comprehensive power consumption reduced by 3%.
8. During the electrowinning process, the lead leaching rate is reduced by 99%, and almost no anode slime is generated. Therefore, the cathode product has a very high purity, and there is no need to stop production to clean up the anode slime, which can significantly improve production efficiency.
The Next-Generation Anode: Engineered to Slash Operational Costs and Enhance the Purity of Cathode Product
Pushing the boundaries of productivity in electrowinning requires innovation that delivers measurable financial impact. While traditional lead alloy anodes have been the industry staple, they come with inherent limitations in efficiency and maintenance costs. Our Titanium-based Lead Dioxide (Ti/β-PbO₂) Anode represents a technological leap forward. Designed for the most demanding copper and zinc electrolytes, it is engineered to significantly extend service life, eliminate anode-related contamination, and reduce the total cost per ton of metal produced.
Advanced Structure and Process: The Anatomy of the Service Life
The superior performance of our titanium-base lead dioxide anode plate is rooted in its multi-layered, composite structure, each layer serving a critical function.
1. Robust Titanium Substrate:
We start with a high-strength, industrial pure titanium base. Titanium is chosen for its exceptional corrosion resistance in acidic environments, forming a stable, passive oxide layer that serves as the unbreakable backbone of the anode. The substrate is meticulously sandblasted degreasing and pickling processes to ensure perfect adhesion for the subsequent layers.
2. Precision Intermediate Coating:
A critical step for long-term performance. We apply specialized nanobuffer intermediate layer onto the titanium substrate. This layer is crucial for preventing oxidation of the titanium and ensuring excellent bonding force and electrical conductivity between the substrate and the active coating, while also providing a superior barrier against corrosion.
3. Electrodeposition of Active Layer:
The core of the anode’s functionality is the thick, dense, and highly crystalline Beta-Lead Dioxide (β-PbO₂) coating. This layer is electrodeposited under controlled conditions of temperature and current density. The resulting β-PbO₂ coating is non-porous, possesses high oxygen evolution potential, and is extremely resistant to chemical attack, making it the ideal catalytic surface for the oxygen evolution reaction.
