The invention relates to the field of
nickel electroplating, and discloses a plating solution formula for continuously
electroplating satin
nickel and a process.The satin
nickel plating solution formula comprises the following components in proportion by weight: 500-560g / L of nickel
sulfate pentahydrate, 25-35g / L of nickel
chloride, 40-50g / L of
boric acid and a non-ionic surfactant; and the non-ionic surfactant comprises the components in proportion by volume: 32-36 ml / L of a cylinder opening agent, 4.0-6.0 ml / L of an auxiliary agent and 0.8-1.2 ml / L of a sand agent. The process comprises the steps of pretreatment->nickel pre-plating-> satin nickel plating->semi-gloss nickel plating->water repelling. Compared with the prior art, the formula of the satin nickel plating solution formula and a saltin nickel plating layer electroplated by the
electroplating process have the advantages that the glossiness of the saltin nickel plating layer is stabilized at 40-80, the appearance is uniform, yellow spots are avoided when the saltin nickel plating layer is exposed in air, the maintenance period of the saltin nickel plating solution is obviously prolonged, and the saltin nickel plating layer is treated and maintained once a month by
activated carbon.
