How Does an Electrostatic Spray Painter Work?
Purpose of the Electrostatic Spray Painter A spray painter propels a cloud of atomized paint at a surface to be painted. Because the paint particles are spread out, the paint creates a uniform covering, getting on everything in front of it fairly evenly, but normal spray painting is not perfect. The cloud may be denser in the middle, creating an uneven paint job. There is also the problem of overspray – clouds of paint particles that get in the air, posing a health problem and getting on things that they aren’t meant to. An electrostatic spray painter helps to reduce both of these problems Charging the Paint There are several different ways that the paint can be electrostatically charged. In some systems, a negative electric charge is applied to the paint while it is actually in the reservoir. In other systems, the charge is applied while the paint is in the barrel of the spray painter gun. Compressed gas propels the paint through the gun, where it rubs against the side, gaining a stat
