Used by domestic users, it has the following advantages:
The weight of the electrode is relatively light and the operation is more convenient.
Long service life, 1-2 times that of lead-based alloy anodes.
The electrode adopts a mesh structure, the current is more uniform, and the fluidity of the electrolyte is improved.
The labor expenditure is reduced. Since there is no lead sulfate falling off, there is no precipitation at the bottom of the electrolytic cell, thereby reducing the number of personnel, and at the same time avoiding the deposition of conventional electrolysis, which needs to be returned to the high level of fire treatment. pollution and high energy consumption.
Since there are no Sn, Sb, Ag and other ions in the coating, there will be no secondary pollution to the solution, and the cathode copper produced can reach 4N5 or above or A-grade copper standard.
The solution conditions for the electrolyte are wider.
Application areas: electroplating copper, nickel, cobalt, etc. in the hydrometallurgical industry, electroplating, metallurgy, domestic sewage treatment, persulfate production, phenol-containing wastewater fading treatment, oil field wastewater, printing and dyeing wastewater, ammonia nitrogen wastewater treatment and other fields.
