Common Problems and Solutions for Electrostatic Spraying, Understand It Through One Article!

Although electrostatic spraying is an advanced coating process, some common problems may also be encountered during the actual operation process. Today, we will interpret these problems in detail for you and provide effective solutions.

Problem One: Uneven coating thickness. This may be caused by inconsistent distances between the spray gun and the workpiece or uneven spraying speeds. The solution is to precisely adjust the distance between the spray gun and the workpiece before operation and maintain a stable spraying speed. Meanwhile, regularly check the atomization effect of the spray gun to ensure that the paint can be sprayed evenly.

Problem Two: Pinholes or bubbles appear. This is often due to the presence of water or air in the paint and improper surface treatment of the workpiece. To solve this problem, it is necessary to fully stir and filter the paint before spraying to remove the water and impurities therein. Also, conduct a thorough cleaning and degreasing treatment on the surface of the workpiece to ensure that the surface is clean and dry.

Problem Three: Leakage occurs during electrostatic spraying. This may be caused by poor grounding of the equipment or damage to the insulation of the spray gun. At this time, it is necessary to promptly check the grounding system of the equipment to ensure good grounding. Meanwhile, regularly check the insulation parts of the spray gun, and if there is any damage, they should be replaced immediately.

Understanding and solving these common problems can make your electrostatic spraying process smoother and ensure better product quality. We hope that this article can provide some practical help for friends engaged in electrostatic spraying work.
