What causes the coating to peel off easily after zinc alloy electroplating? The degreasing of the workpiece is closely related to whether it is done properly. In this article, we will analyze the reasons and how to choose chemical degreasing powder.
Whether the oil removal is thorough is an important factor affecting the adhesion of the coating. When degreasing zinc alloys, caustic alkali should not be used, nor should high temperatures be employed or the workpieces be immersed in the degreasing solution for a long time. Generally speaking, you can first use Bigely chemical degreasing powder BC-1103 to remove the residual oil stains on the surface.
When using the chemical degreasing powder BC-1103, Bigely recommends ultrasonic cleaning, which can significantly enhance the degreasing effect, especially on blind holes, grooves and concave surfaces. After degreasing, water washing should be done well to clean the residual alkaline solution on the surface and in the crevices as much as possible. If you scrub with a soft-bristled water-polishing brush or wipe with a soft cloth and soft-bristled brush, you can also achieve a good oil removal effect.
