The first patent on electrostatic spraying was issued in 1932. The idea of electrostatic spraying was being examined early in the 1940´s and since then various sprayers and commercial machines have been developed.
One of the first important applications of electrostatic technology was spray coating in the automobile industry. The paint spraying industry recognized the benefits of electrostatic spraying of paint finishing early. Today most all farm machine and appliance manufactures worldwide use various types of electrostatic sprayers for coating and painting applications. Practically all the sandpaper manufactured in the world is produced by electrifying the abrasive particles in deposition on the backing material.
The principle of applying a PCO Coating is the same. A charged cloud of antimicrobially active droplets is driven by electrostatic force towards an object or surface. When the charged droplets exit the spraygun of the electrostatic sprayer, those charged droplets are forced to move along field lines according to Coulombic forces. Since the electrostatic force is much stronger than gravitational or inertia forces for a small droplet, the motion of the charged droplet is easily controlled by the electrostatic force.
It is possible for droplets to reverse their flight path and coat areas of the target that would not otherwise be coated with uncharged spray. Such attraction can only occur if electrostatic forces on the droplets are dominant over gravity, inertia, and the force of air currents. Typically that means droplets less than 100 microns in size give best results.
Microbecide® Electrostatic Sprayers use air-assistance for better spray delivery. Air is necessary in electrostatic spraying to cause the charged coating to push deep into complex targets. Electrostatics, with air-assist, plus the right droplet size is a perfect combination for the most effective and efficient application of a coating. The force of electrostatic attraction is strong if the droplets are small and the droplet charge is sufficiently high.
Electrostatic sprayers are ideal for schools, day care centers, nursing homes, clinics and hospitals, gyms and spas, hotels, public transportation, restaurants, mold remediation firms and others for decontamination, disinfecting and odor elimination. They are also used by greenhouses, nurseries, and grounds staff for application of insect control products on plants and flowers.
