Cathode Plate Edge Strip

Cathode Plate Edge Strip | PP Modified Edge Clamp

In copper electrolysis and electrowinning tankhouses, stainless steel cathode plate edges are constantly subjected to dual stress: frequent friction with electrolytic cell walls during hoisting and stripping, and long-term immersion in sulfuric acid electrolyte (typically 180-220g/L concentration). This often leads to edge wear (up to 0.3mm/year under unprotected conditions), deformation, and localized corrosion-directly causing uneven current distribution, rough cathode copper edges, and shortened cathode plate service life (reduced by 30-40% on average). As a dedicated protective accessory for cathode plates, PRS's cathode plate edge strip is installed on both sides of the plate to form a robust protective barrier.

PRS's cathode plate edge strip is manufactured in strict accordance with GB/T 20202-2018 industrial standards and our own on-site test data, with precise dimensional control to ensure perfect compatibility with 316L, LDX2101, and 2205 stainless steel cathode plates (the most commonly used models in copper tankhouses). All parameters are verified through 1,000+ hours of immersion testing in simulated electrolyte environments, ensuring reliable long-term performance.

• Material: Self-developed PP modified material (15% glass fiber reinforced) – tested to resist 220g/L sulfuric acid electrolyte at 55℃ for 1,500 hours without aging, deformation, or corrosion. It outperforms ordinary PP material in wear resistance (abrasion loss ≤0.02g/cm²) and mechanical stability, fully adapting to the acidic, high-friction environment of copper electrolysis cells.
• Clamping Plate Thickness: 3.0mm (±0.05mm tolerance) – precisely matched to the thickness of standard stainless steel cathode plates (2.5-3.0mm). The design ensures firm clamping without damaging the plate edge, and no loosening occurs even under strong electrolyte flow (up to 0.8m/s) or mechanical vibration during hoisting.
• Product Set Composition: 1 set includes 1 tension rod + 1 edge strip (length customizable: 1.2m-3.6m, matching cathode plate length). The tension rod is made of the same PP modified material for consistent corrosion resistance, and the set is pre-assembled for on-site use-no additional accessories or tools are required, reducing installation time by 40% compared to split-type edge strips.
• Surface & Cutting Requirements: The product surface is polished with a 600-mesh abrasive, ensuring smoothness (surface roughness Ra ≤0.8μm) and uniform color (no color difference within a single batch). The saw cut edge is deburred by a fully automatic machine, with no obvious burrs or flashes-field tests show it causes zero scratches on cathode plate surfaces during installation, avoiding potential short circuits caused by scratch-induced copper deposition.

Tailored for stainless steel cathode plate matching, PRS's edge strip integrates material innovation and on-site operational needs, solving practical problems for electrolytic production and bringing tangible economic benefits to tankhouses:

• Superior Corrosion Resistance: The glass fiber-reinforced PP modified material is specially formulated for copper electrolysis. On-site data from 12+ copper tankhouses shows it maintains stable performance for 5+ years in 180-220g/L sulfuric acid electrolyte, with no aging, deformation, or corrosion-extending the edge strip's service life by 2+ years compared to ordinary PP edge strips.
• Firm Clamping: The 3.0mm thick clamping design, combined with the integrated tension rod, forms a "double fixation" structure. Field tests confirm it remains tightly attached to the cathode plate edge even after 500+ hoisting and stripping cycles, preventing loosening caused by electrolyte flow or mechanical vibration-reducing edge strip replacement frequency by 60%.
• Protective Performance: The smooth, burr-free surface avoids scratching the cathode plate, while the edge strip effectively isolates the plate edge from electrolyte corrosion and cell wall friction. On-site practice shows it reduces cathode plate edge wear by 80%, extending the overall service life of the cathode plate by 30-40% and reducing replacement costs significantly.
• Easy Installation & Disassembly: The integrated design eliminates the need for complex tools-only a 1.5kg rubber hammer is required for installation. A single worker can install 15-20 sets per hour, saving 40% of labor costs compared to traditional split-type edge strips. Disassembly is equally simple, facilitating cathode plate maintenance and edge strip replacement.
• Consistent Quality: We implement a 3-stage quality inspection process (raw material testing, production process sampling, finished product immersion testing) to ensure uniform product size (dimensional tolerance ≤±0.05mm), smooth surface, and stable performance. Batch consistency is verified by random sampling of 5% of each batch, ensuring no quality differences between products.

The installation and removal of the cathode plate edge strip are simple and efficient, requiring only a 1.5kg rubber hammer (no special tools needed). To help on-site workers master the operation quickly, we provide a detailed installation video-contact our team to obtain it, which includes on-site operation demonstrations, common problem solutions, and safety tips.

Installation Steps:

1. Take out 1 set of edge strip and tension rod, and inspect the product for integrity: check for cracks, burrs, or color unevenness (any defective product can be replaced free of charge within the warranty period).
2. Align the edge strip with the side of the stainless steel cathode plate (ensure the clamping groove is fully fitted with the plate edge), then use a 1.5kg rubber hammer to gently knock the edge strip into place-tap evenly along the length of the edge strip to ensure it is closely attached to the plate edge with no gaps (avoid excessive force to prevent edge strip deformation).
3. After the edge strip is in place, insert the tension rod into the reserved hole of the edge strip, and gently knock it into position with the rubber hammer-this further tightens the edge strip and ensures firm clamping, preventing loosening during electrolysis or hoisting.

Post-installation Check: After installation, gently pull the edge strip to confirm it does not loosen; check the fit between the edge strip and the cathode plate-no gaps or warping are allowed. If any issues are found, adjust the position or replace the product in time to ensure the protective effect.
