Electrostatic Spraying Technique
Electrostatic spraying is a method that utilizes a high-voltage electrostatic field to efficiently apply coatings to workpieces. This technique involves inducing negatively charged coating particles to move towards the oppositely charged surface of the workpiece, ensuring a strong adherence of the particles.
Operational Principle
During operation, the spray gun’s spray disc or spray cup is connected to the negative electrode of the coating particles, while the workpiece is connected to the positive electrode and grounded. This setup, coupled with the high voltage supplied, allows for the efficient application of a thicker coating in a single pass.
Equipment Used
- Spray gun
- Spray cup
- High-voltage power supply dedicated to electrostatic spraying
Benefits of Electrostatic Spraying
One of the key advantages of electrostatic spraying is its ability to achieve a uniform coating thickness while minimizing overspray, resulting in cost savings and improved efficiency.
