Description

Technical Field

[0001] The invention relates to the technical field of electroplating liquid purification, in particular to electroplating liquid purification equipment. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics. During the electroplating process, metal residues, dust, oxide scale, metal oxides, sulfate, chloride ions, nitrates and other impurities are often generated in the plating solution. When they reach a certain concentration in the plating solution, they will affect the stability of the plating solution and the electroplating effect. Therefore, electroplating solution purification equipment is used to purify the plating solution so that it can be recycled.
