In the production process of using decorative chrome plating additives, sometimes the workpiece coating will appear pitting, which will seriously affect the appearance and performance of the workpiece, and also affect the service life of the workpiece.So how can we avoid this phenomenon?
When we use chrome plating additives, we will find that the anode plate used for chrome plating is special, which is insoluble anode plate such as lead and lead alloy.Why is this?
In the production process of using chrome plating additives, sometimes the coverage of the coating is very poor, which will directly affect the quality of the coating.So what factors affect the coverage ability of the chrome layer?
When we use galvanized trivalent chromium black passivator to produce, sometimes the black color of the passivation film of the workpiece is uneven, and some do not form a film on the edge of the workpiece.At this time, the appearance of the workpiece is very bad, and the corrosion resistance is also very poor.So, what causes this?
In the process of using alkaline zinc plating additives, we sometimes use CK-778 purifier to treat the plating solution, which can effectively remove heavy metal impurities and adsorb the decomposition products of additives, and has a good adsorption effect on oil stains and suspended solids.However, the end point of the plating solution treated with CK-778 purifying agent is not obvious during the titration analysis of zinc ions, which will lead to inaccurate analysis of zinc ions. What is the reason?
With the development of production technology in the electronic component industry, people have higher requirements for coating quality, and the requirements for product coating thickness, uniformity, hardness and brightness are higher.However, the ordinary tin plating process can not meet the needs of production, and the product performance is difficult to meet the requirements, which requires the use of high-speed tin plating additives.
