Microbecide® Electrostatic Systems with induction charging nozzle technology. |
Nano coatings are composed of extremely tiny particles that possess unique characteristics -- like extreme flexibility, easy adhesion and resistance to corrosion and microbial growth. Electrostatic application of a nano coating employs the principles Coulomb's Law, where opposite electrical charges attract and "like" charges repel. Just as metal filings are drawn to a magnet, lint is attracted to your clothes or dust attaches on a record. In science, it is known as Coulomb's Law, where opposite electrical charges attract and "like" charges repel.
Electrostatic coating systems are being used to apply nano coatings on everything from bananas and potatoes, to hospital rooms needing complete antiseptic coverage. The concept is to create opposite electric charges between the "coating" and the object.
Electrostatic application begins with the spray nozzle. A typical droplet of spray from a conventional air-blast applicator is around 250 microns. Microbecide® electrostatic systems use an air-assisted nozzle, whereby the nano coating solution is combined in a shearing action, and atomized down to a 30 to 50 micron droplet size. Then, just before the coating mist exits the nozzle, it is exposed to a negative charge. As the mist envelopes the target, it stalls, resulting in a charged fog around the target; this is when the Microbecide® magic begins.
The electrically-charged mist is strongly attracted to the targeted object. The charge on the coating particles is small, but the force attracting the coating mist to the target is substantial, up to 75 times the force of gravity. The particles actually reverse direction and coat the underside, backside and crevasses of the target, creating an "electrostatic wraparound." In comparison, a 250-micron droplet simply runs off a target and is largely wasted.
Additionally there is the second half of Coulomb's Law, that "like" charges repel. Since all of the coating particles leaving the nozzle have the same charge, they cannot collect into large droplets, which again fall off the target. At the same time, the swirling particles are not attracted to areas already coated and continue to seek out uncovered surface areas until there is uniform coverage (disposition) across the entire target. Essentially the entire target is "nano coated" with no drips or runs.
Since microscopic organisms are usually hidden in deep cracks and crevasses inside the target or on the undersides of surface areas, they can continue to survive if the spray coverage is spotty. The distinct advantages of an electrostatic applicator are the complete coverage and the extended contact time of the disinfectant with the target. Bacterial and viral strains of all kinds are becoming more and more resilient and harder to eradicate. Experience is showing it is not just what is applied but how a coating is applied that matters most.
