High-Quality Permanent Stainless Steel Cathodes from China Suppliers and Factory for Hydrometallurgy Applications
Product Description
1. Material properties
- Strong corrosion resistance: Made of high-quality stainless steel (such as 304, 316, 316L, etc.), it can resist the corrosion of electrolyte (often containing sulfuric acid, chloride ions, etc.), and has a long service life.
- High electrical conductivity: The surface is usually specially treated (such as polishing, coating) to reduce contact resistance and improve current efficiency.
- High mechanical strength: Stainless steel has good rigidity, is not easy to deform, and can withstand mechanical stress during hoisting, transportation, and stripping.
2. Structural Design Features
- High flatness requirement: The surface of the plate is extremely flat (the tolerance is usually ≤ ±2mm/m²), ensuring uniform metal deposition and avoiding short circuits or local over-thickness.
- Optimized edge sealing: The edges are designed with flanging or sealing to prevent the deposited metal from wrapping around the edges, facilitating stripping.
- Robust lifting lug structure: The lifting lugs are firmly welded to the plate body with a reasonable design, facilitating hoisting by crane and stripping operations.
- Lightweight design: The thickness is optimized under the guarantee of strength to reduce weight, lowering material and transportation costs.
3. Performance Characteristics
- High deposition efficiency: Smooth surface finish, fine metal crystallization, uniform adhesion, and easy stripping.
- Long service life: Corrosion-resistant and wear-resistant, can be reused thousands of times, and has low maintenance costs.
- Energy-saving and consumption reduction: Good electrical conductivity, reduces cell voltage, and minimizes electrical energy loss.
- Convenient operation: Humanized design, easy to hoist, align, and strip, enhancing production efficiency.
4. Economy and Environmental Protection
- Low comprehensive cost: Although the initial investment is relatively high, its long service life and low maintenance cost make it highly economically beneficial in the long term.
- Environmentally friendly: Stainless steel can be fully recycled, reducing waste; the optimized electrolytic process lowers energy consumption and pollution.
