REM Automatic Applicator - Introduction
REM PROCESS REM PROCESS REM PROCESS REM PROCESS REM PROCESS
This is an air assisted method for electrostatically
applying coatings to objects. The REM system
applies a high voltage DC charge to the applicator
nozzle electrode, creating an electrostatic field
between the atomizer and the target object. The
target is electrically grounded through its support
which may be either stationary or moving.
A regulated pressure fluid system delivers coating
material to the atomizer. There the coating material
is atomized by passing through an orifice under
pressure, the resulting spray mist under the
influence of the electrostatic field, becomes
electrically charged. The air supply to the
applicator is adjustable at the rear of the applicator
and aids in shaping the coating material into a
desired pattern. The charged particles are
attracted to and deposited on the target object.
The forces between the charged particles and the
grounded target are sufficient to turn most normal
overspay around and deposit it on the back
surface of the target. Therefore, most of the spray
is deposited.
A control unit provides either manual or automatic
operation of the equipment. Controls normally
include, but are not limited to atomizing, triggering,
and shaping air, fan, and conveyor interlocks and
a protective current overload device.
