DONGSHENG offers premium recycling for seawater electrolysis nickel mesh, primarily from two brands: Italy's De Nora with DSA-coated nickel mesh and China's Baoji Yinggao Metal with foam nickel mesh. Both brands possess mature expertise in salt-spray corrosion resistance and high conductivity.
Pollution Control in Seawater Electrolysis Nickel Mesh Recycling: Residual seawater salts require freshwater rinsing. Otherwise, smelting generates dioxins, increasing processing costs by 30%.
Seawater electrolysis nickel mesh must simultaneously meet conductivity, corrosion resistance, and mechanical strength requirements. Core parameters are as follows:
Parameter Category | Technical Specifications | Impact on Electrolytic Performance |
Material & Purity | N4 grade (Nickel ≥99.9%) | High-purity nickel reduces Cl⁻ corrosion rate |
Mesh Size & Aperture | Coarse filter: 10–60 mesh (0.3–1mm aperture) | Small apertures clog easily |
Thickness & Strength | Woven mesh: 0.1–0.6mm | ≥0.3mm required for deformation resistance in high-pressure seawater |
Conductivity | Surface resistance ≤0.1Ω/□ | Directly affects energy conversion efficiency |
Porosity (foam nickel) | ≥95% | High porosity increases electrolyte diffusion & bubble release speed |
Salt Spray Resistance | ≥720h no pitting (ASTM B117) | Ensures >5-year lifespan in marine environments |
