Electrostatic spraying is a method used for coating. It uses gun spray to create an electrical charge on powder particles. The aim of electrostatic process is to get as much coating material to create an electrical charge on powder particles and this is achieved by negatively charging atomized paint particles.
A charging electrode is situated at the tip of the electrostatic gun. The paint, either in powdered form or atomized form moves past the electrode and its particle become ionized- negatively charged, due to which electrostatic field is created between ground work piece and charging electrode. In electrostatic spray finishing, an electric field is generated through ionizing needle. The benefits of this spray finishing are due to the electric fields between the needle and the grounded object, and the fields between the charged paint particles and the grounded object.
Electrostatic spray guns have numerous benefits especially for commercial painting or site spraying. Let’s have a look at these amazing benefits of electrostatic spray painting:
Electrostatic spray guns have numerous benefits especially for commercial painting or site spraying. Let’s have a look at these amazing benefits of electrostatic spray painting:
- High-efficiency: These guns are truly efficient. When paint particles are charged, the paint adheres to the surface of the painting. There is a wrap-around effect in which particle change directions to adhere. The process is used for the purpose to coat the object that is intended to paint. Therefore wastage is less comparatively.
- Saves money: Although they have larger upfront investment, the efficiency gains of gun make it much cost-effective. Due to less wastage paint and material costs decrease significantly. Also due to its great paint adhering property less cleanup is required.
- Paint all types of objects: Due to its wrap-around effect, electrostatic spray guns are ideal for painting all types of objects such as poles, fences, carvings or engraved surfaces, and porous materials.
