Introduction for Polymer concrete electrolytic cells

The vinylester resin monolithic cast polymer concrete electrolytic cell is a new type of environmentally friendly electrolyzer equipment. The cell body is composed of 3 layers, a corrosion-resistant layer, a polymer reinforced aggregate structural layer and an outer layer.

By modifying the vinyl resin, controlling the moisture content of quartz sand and the production environment temperature, and conducting Finite Element Analysis modeling and optimization design of the overall structure, the product is anti-corrosion, leak-proof, high insulating, high electrolysis rate, and electrolytic quality. It has the advantages of high efficiency, cleanness and environmental protection, precise dimensions, and long service life.

With the continuous improvement requirement for environment protection and the hydrometallurgy's comprehensive performance requirements for enhancing electrolytic products such as quality, environmental protection, and no leakage, Polymer Concrete cell has superior performance that is unmatched by traditional material electrolytic cells.

Different Type of Cells

Copper Cell

The purpose of electrolytic refining of copper is to improve the purity of copper and to recover precious metals in the anode mud. There is high temperature corrosive medium in the tank.

The integral polymer concrete copper cell is one-time molded using modified vinyl resin and high-quality quartz sand.

It has good corrosion resistance, temperature resistance, impermeability and impact resistance.

The electrolyte and anode mud in the cell will not be polluted, the insulation is good, and the cell body does not require maintenance. It is a high-quality cell for copper electrolysis.

Zinc Cell

The integral polymer concrete zinc cell is an electrolysis equipment and can achieve the relatively stable electrolyte temperature, high electrolysis efficiency, low energy consumption, and a simple structure.

Zinc cell is made of modified vinyl and high-quality quartz sand, cast and molded in one-time at a specific temperature. It has excellent properties such as cell insulation, no leakage, maintenance-free, high strength, corrosion resistance, and impact resistance.

Cell body is composed of a corrosion-resistant layer, a structural layer and an outer layer. It is a new type of equipment in zinc electrolysis industry.

Other Cells—Cells for Cobalt, Nickel

The vinyl resin polymer concrete cell is cast with one-time molding and is corrosion-resistant, impact-resistant and leak-proof.

The overall optimized cell occupies small area, has accurate dimension and accurate embedded parts, is easy to install and adjust, also has a long service life.

Reliable quality, excellent performance, and high strength make the polymer concrete cell maintenance-free. avoid frequent repair for other material cell deformation, leakage, or even cell replacements. Thus saved manpower, material, resources and time.

Advantagies of polymer concrete cells

1.Corrosion resistant, Long service life

It is integrally cast using modified vinyl ester resin and high-quality quartz sand, which effectively solves the stress shrinkage and linear expansion problems of electrolytic cells produced by other processes. All materials are anti-corrosive, so they have a long service life. The service life has been verified by actual use to be more than 20 years.

2.No leakage

The chemical barier meet FRP tank chemical barrier domestic and international specification, Such seals are typically composed by 3 layers fiber glass soaked with vinyl ester resin. The production process adopts one-time integral casting technology. The structural layer and outer layer are composed of polymer reinforced aggregate, so that the product will not leak electrolyte and has good leak-proof performance.

3.Improve current efficiency, Improve product quality

Under strong current electrolysis conditions, the use of steel bars can easily generate eddy currents on the cell walls. The overall insulation of the polymer concrete cell is good, the reinforcing ribs are non-metallic, and there is no eddy current, which greatly improves the current efficiency.

Excellent corrosion resistant property, achieved no leakage, thus solved the problem of accessories corrosion caused by liquid leakage, solves the problem of calcium sulfate contamination caused by electrolyte penetration, which affects the quality of cathode plates. Then improves the quality of electrolytic products.

4.High Strength

The polymer concrete cell is made of vinyl ester resin and quartz sand as the base material, and is cast as monolithicly at a specific temperature. The compressive strength is >80MPa, which can effectively avoid damage caused by the collision of cathodes and anodes during operation.

5.Accurate dimension easy to install

The vinyl resin integrally cast electrolytic cell is cast integrally in a mold. It has good integrity, high dimensional accuracy, and accurate embedded parts. It is simple for cell erection, alignment and leveling.

6.Small footprint, Easy repair and short time

Since the monolithic polymer concrete cell has good strength, precise dimensions, and low thermal expansion coefficient, the cell wall can be reduced from traditional 115-150mm to 70-100mm, and the cell spacing can be reduced from 30mm to less than 20mm. Under the same production area, 6%-10% more cells can be arranged, or 6%-10% of the factory area can be saved.

If the cathode or anode plate fall down and cause scratches and cracks on the cell body, easy to repair: rinse this place with clean water and dry，Make a "V"-shape groove at the crack and fill them with mixture of modified vinyl ester resin and quartz sand , then cure 2 hours at room temperature. Furnish the surface, it can be used again.
