Our company can repair the old electrolysis device and transform it into a high-density membrane electrode pitch electrolyzer; maintain the original electrolyzer structure, install nickel elastic mesh, nickel-based mesh and active cathode mesh on the cathode mesh to make the electrode The gap is reduced to the thickness of the film, supplemented by the technology of reducing the bubble effect and the active cathode technology, which effectively reduces the cell voltage and prolongs the service life of the electrode. The cell types include: Beihua Machinery electrolyzer, Asahi Kasei electrolyzer, BiTAC electrolyzer, F2 electrolyzer, Woody electrolyzer, etc.
