When using nickel plating brightener, are you often troubled by iron impurity contamination? Is it that after using electrolysis method, not only can't completely remove impurities, but also lose a lot of nickel salt? Is not the use of impurity remover but become serious, iron ions can not sink, the plating solution becomes cloudy, add hydrogen peroxide to adjust the PH also can not? This article will tell you how to solve the problem.
Steel parts directly rolled nickel plating or tubular workpiece nickel plating, as we all know, in the use of nickel-plated brightener, steel in the acidic solution is very easy to corrode and dissolve, especially steel tubular workpiece nickel plating, nickel plating on the outside, by the nickel layer of protection, so that the steel parts will not corrode and dissolve.
But the depth of the inner wall is not plated on the nickel layer, and for a long time immersed in an acidic solution, parts plated for how long, but also equal to the steel parts in an acidic solution corrosion dissolved for how long.
In this way, a large amount of divalent iron impurities are produced. When the divalent iron is greater than 0.05 g/L, it makes the plating layer rough, appears pinholes and brittleness increases, the porosity of the plating layer increases and the brightness decreases.
When using nickel plating brightener, in order to avoid the above problems, we can use Bigely nickel plating iron remover Ni-392, which adopts the masking coordination method to deal with the iron impurities, the principle is to change the deposition potential of iron impurities, so that the iron impurities can be co-deposited with nickel ions and purify the iron impurities in the nickel solution in the form of nickel-iron alloy plating layer. So there is no need for filtration equipment, no need to stop production and small current electrolysis, as long as the addition of nickel-plated iron remover slightly stirred, can be normal production.
