[0002] Electroplating chemical liquid can expand the cathode current density range of metals, improve the appearance of the coating and increase the anti-oxidation stability of the solution. Electroplating liquid refers to a liquid that can expand the cathode current density range of metals, improve the appearance of the coating and increase the anti-oxidation stability of the solution.
