The EGL process requires very robust anodes and highly customized solutions to meet a wide variety of production requirements. De Nora serves any type of cell configuration including vertical or horizontal cell alignments and radial cell designs.
The use of De Nora DSA® anodes for EGL requires a particular focus on the stability of the coating to compensate for the type of chemicals present in the operational electrolyte composition.
Proper engineering design considerations must also take into account a range of operational current density of 5 to 15 kA/m², with anode size varying from 0.15 to 2.65 m². Our family of oxygen-evolving mixed-metal oxide (MMO) coatings are capable of meeting customers’ requirements in terms of lifetime, performance, and cost.
The operation of De Nora DSA® anodes in EGL processes promotes plating uniformity across the web of the steel coil. This ensures an outstanding corrosion resistance, formability, and paint adhesion when zinc electroplating for the automotive and appliance market.
De Nora focuses its efforts in providing flexible solutions, offering significant advantages over competitors’ technology:
The use of De Nora DSA® anodes for electrotinning also requires a particular focus on the stability of the coating to compensate for the type of chemicals present in the operational electrolyte composition.
We provide tailored MMO coatings suitably formulated for operation in either Methyl Sulfonic Acid bath (MSA) or in Phenyl Sulfonic Acid bath (PSA).
De Nora DSA® anodes for this application are characterized by:
