Electrolytic Cells for Electrowinning of Non-Ferrous Metals

2.Structure Electrolytic cells are cast monolithically based on a patented, three-layer composite material system: The Internal layer is a monolithic tank made with multiple layers of fiber-reinforced vinyl ester resin (FRP) complying with chemical barrier international norms that assure long-term impermeability and corrosion resistance. The Intermediate layer is the structural core made with polymer Concrete, with a patented formulation to achieve a low coefficient of thermal expansion, providing long-term structural integrity with low thermally-induced stresses The External layer is a standard seal layer of FRP that further protects the structural core from electrolyte splashes and spills. Optionally，this external seal may be specified with multi-layered oriented fiber reinforcements to guarantee trouble-free operation in unusually extreme operating environments.
