Super tank Polymer Concrete Electrolytic Cells are designed, built and installed to satisfy the most stringent requirements requested by tank house operators worldwide. In most case their main request is to guarantee full operating availability throughout the plant' s lifespan, maximizing production of high-purity metal (copper, zinc, nickel, cobalt, lead or other) with absolute safety for people and the environment.
Additionally, Polymer Concrete Electrolytic Cells must accommodate changes for continuous improvement of electrolytic process, integrating efficiently with upgrades of complementary equipment such as anodes, cathodes, cap boards, overhead crane, electrolyte agitation systems, acid mist control devices, thermal insulation, among many others.
Super tank electrolytic cells are cast monolithically based on a patented, three stratum composite material system.
the internal stratum 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 stratum is the structural core made with Hyperbonded 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 stratum 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.
