Application of vinyl resin monolithic electrolytic cell

Epoxy vinyl ester resin has a special molecular structure and has better corrosion resistance and temperature resistance than epoxy resin and unsaturated polyester resin. It is widely used in anti-corrosion projects in chemical, energy, smelting, biology, medicine, electronics, power and other industries, especially in the non-ferrous smelting industry of metal copper. Due to its production process requirements in the wet electrolysis process, a higher concentration of electrolyte is required. The crude copper plate is electrolyzed under certain temperature conditions to obtain refined copper. This process requires the equipment for storing the electrolyte to have higher corrosion resistance and higher impact resistance.

Copper smelting electrolyte usually uses sulfuric acid and copper sulfate as mother liquor. Cathode refined copper is obtained by electrolyzing anode copper at 60~80 degrees. The electrolyte is highly corrosive. In the early days, concrete electrolytic cells were usually used, and vinyl resin was used to make FRP lining anti-corrosion layer to protect the concrete tank body. However, after long-term immersion in electrolyte and collision of electrolytic plates, the FRP lining anti-corrosion layer is easily damaged and protection fails. The service life is as short as 1~2 years and as long as 3~5 years.

The vinyl resin electrolytic cells used and produced by our company not only have good corrosion resistance and anti-penetration characteristics, but also have better impact resistance, maintenance-free and long service life cycle advantages compared with conventional fiberglass lined concrete electrolytic cells.
