It's quite simple, really. Our aim is
to eliminate wasteful overspray and get as much coating material
on the target as possible. This is achieved by negatively
charging atomized paint particles so that they are attracted
to the grounded workpiece, opposites attract.
A charging electrode is located at the
tip of the electrostatic spray gun or atomizer. The paint
is atomized as it moves past the electrode, and its particles
become ionized - negatively charged. An electrostatic field
is created between the charging electrode and the grounded
workpiece, and the spray is concentrated within it.
Further atomization is achieved as charged
particles repel each other to form a fine cloud. As a result
of electrostatic attraction, spray that would normally be
lost ends up on the back and sides of the workpiece to produce
a "wrap-around " effect.
Why Electrostatic?
Electrostatics is an environmentally responsible
way to atomize paint, because it significantly increases quality
and production, equally decreases paint costs, VOC emissions
and maintenance, and makes change of coatings easy.
The Advantages Are...
- Increased transfer efficiency and reduced
overspray, which results in significant cost savings and
reduced VOC emissions.
- No down time. Items can be refinished
in the evening and be operational the next morning.
