Simple-Paint System - Operating Principle

“Any rubbing between one or more bodies produces an electrostatic charge”

In the non-electrostatic painting process, rubbing occurs.

This produces low static charges that disturb the operator during paint application.

More precisely, these charges are generated at two specific moments:

  • the rubbing of the atomised paint when it passes through the gun nozzle (small density charges are generated on the tip of the gun that dirty the operator's hand with paint);
  • the rubbing of the atomised paint pushed on the surface of the object during painting ( this rubbing generates a higher quantity of static charges that disperse the paint on the operator and on the walls of the booth).

This rubbing action charges the paint particles (or dust) electrostatically.

These particles discharge the static energy on the bodies, or in the areas closest to them (painting booth, operator and object) where the concentration of static charges is lower, causing:

  • dispersion of paint in the environment (over-spray),
  • a paint rebound effect onto the operator,
  • paint spreading, uniformity and accumulation (dripping) problems;
  • the tendency of the object to attract dirt and dust.
