Bright nickel plating process is widely used in automobile, electronics, architecture, decoration and other industries because of its good decorative and anti-corrosion properties. However, in the plating process, the surface of the coating sometimes appears speckle phenomenon, which not only affects the aesthetic effect of the coating, but also may reduce its corrosion resistance. This paper discusses the main causes of the glitter failure on the surface of bright nickel plating layer, especially the two key factors of unclean oil removal and the use of wrong brightener, and puts forward the corresponding solutions.
Cause of speckle fault
The main causes of bright nickel plating surface speckle failure include the following aspects:
1. Incomplete degreasing:
Failure to thoroughly clean oil, dust and other organic impurities on the surface of the substrate will directly affect the adhesion and uniformity of the plating layer, resulting in the inability to form a uniform nickel deposition layer, triggering the phenomenon of splotch.
2. Use of incorrect brightener:
Nickel plating brightener plays an important role in the surface effect of bright nickel plating. The use of unsuitable brighteners, e.g. brightener failure, wrong formulation or substandard quality, can lead to a lack of surface gloss, poor uniformity of the plated layer, and lead to speckle failure. For this reason, we can use Bigely nickel brighteners to obtain nickel plating with good surface quality.
Solutions
In view of the speckle failure on the surface of bright nickel plating layer, especially the two main reasons of unclean oil removal and the use of wrong brightener, the following measures can be taken:
1. Strict degreasing:
Use a good degreaser: Choose a degreaser with a good, fast degreasing effect to ensure that the surface of the substrate is thoroughly degreased.
Enhance cleaning process: Remove as much residual oil and impurities from the surface as possible through ultrasonic cleaning or multiple water washes.
2. Correct use of brightener:
Choose the right brightener: According to the process requirements, choose the right formula, reliable quality brightener.
Regular detection and replacement: regular detection of brightener components, find problems in time to replace, to ensure its activity and effect.
Conclusion
The surface speckle fault of bright nickel plating layer is a common problem that affects the quality of the coating. By ensuring thorough oil removal and the use of Bigely nickel brightener, speckle faults can be prevented and resolved, and the quality and aesthetics of the coating can be improved.
