ESS sprayers improve target coverage and use less spray material. This
virtual demonstration shows the results. (Click image to enlarge.)
First, we setup the test spraying apparatus.
Next, we take a black plastic sphereand place it a set distance from
the spray nozzle.
Now, we spray the sphere with electrostatics turned OFF: 1-2-3-4
seconds. (The setup is the same; the black background was added to make
the spray more visible.)
Notice the coverage
on the target.
Finally,
we turn electrostatics ON, and spray a new sphere for half the time:
1-2 seconds. (All other settings are kept constant, so half the amount
of material is sprayed.)
Notice the coverage on the target. The charged droplets wrapped around,
reaching the back of the sphere.
