Electrolyzer of Electrorefinning of Zinc, Lead, Gold etc

       Electrolytic cell consists of three layers, the internal layer which contact with electrolytic solution and the external layer are FRP, middle layer is resin mortar. Materials be used are excellent corrosion-resist vinyl ester resin,high purity acid-resist quartz aggragates, glassfiber rebar and auxiliary agents, adopt monolithic casting process, no secondary lamination to internal layer, it makes electrolytic cells with high mechanical strength, excellent corrossion-resist and leakage-proof, technical defects of electrolytic cell with re-lining be resolved fundamentally.

     Our monolithic casting electrolytic cells have high compression-resist, adopt advanced vibrating process, to guarantee it's compactness and strength. Internal layer is corrosion-resist FRP which can improve properties of corrosion-resist & leakage-proof and service life be extended. FRP rebar make cells with high strength, thin wall thickness, insulation and isolation, investment of tankhouse and auxiliary equipments be saved, and electrolytic efficiency be improved. We use monolithic steel molud manfacturing process and our exclusive hydraulic demoulding technology (patented), to improve production efficiency.

1.Vinyl ester resin monolithic casting electrolytic cells
Electrolytic cells are designed, built and installed to satisfy the most stringent requirements requested by tankhouse operators worldwide. In most cases 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 nonferrous metals) with absolute safety for people and the environment. Additionally, cells must accommodate changes for continuous improvement of the 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.
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.
