Electrostatic spraying gives a more even, full coat of spray unlike other spray methods.
When paint which is positively charged is sprayed onto a negatively charged surface, paint particles are attracted to the surface much like a magnet.
Because the entire surface has a negative charge, the entire surface is covered by paint. This leads to complete, uniform coverage. Once the surface is covered by paint particles, the remaining airborne particles become too far away from the surface to be attracted by the negative charge. This leads to an even coat throughout the surface.
Because of the nature of the charged particles, electrostatic spraying can get to hard-to-reach areas, crevices, around corners, and back sides of surfaces. This is beneficial as electrostatic spraying will reach areas that could not otherwise be reached when using brushes, rollers, other sprayers, or other methods.
Electrostatic spraying has been used in the automotive and other coatings industries for years. With technological advancements, it is gaining traction for efficiency and effectiveness in the cleaning industry. Not by applying paint, but by applying cleaners and disinfectants.
When it comes to cleaning surfaces and objects, traditional wet and dry dusting and cleaning methods tend to be the first methods that we think of. These cleaning methods do little more than spread dirt and grime around, unless the rags used are washed regularly. Dry dusting moves the resting particles; most often with a large portion of them becoming airborne spreading to already cleaned areas. Wet cleaning often involves methods that make it hard to reach certain spots or objects. When you are dealing with sensitive spaces, like hospitals, R&D areas, educational institutions and even homes of people who are at high-risk for infection, the best way to clean and sanitize is using the electrostatic method.
Virtually any liquid can be electrically charged and applied onto a variety of surfaces. Most common surfaces (walls, floors, and fixtures) are naturally grounded, meaning they have a negative charge. When a liquid is positively charged, it will fully coat the surface. This is particularly effective for cleaners and disinfectants. By using an electrostatic sprayer system, all surfaces can be coated with a cleaner or disinfectant, and the room will be much more efficiently and completely cleaned.
The most useful cleaning method that is being utilized with electrostatic spraying is disinfecting. To effectively disinfect a surface, you must fully coat a surface and leave it wet for a recommended contact time. For most disinfectants, this means ensuring the surface remains wet for 10 minutes.
In most cases, surfaces are sprayed and wiped almost immediately. Electrostatic spraying solves this issue allowing you to spray the entire room with disinfectant and leave it to air dry. This makes the disinfection process easier, more effective, and more efficient.
One other disinfecting issue, regardless of the method of application, is ensuring that all surfaces are disinfected. Traditionally, hard-to-reach areas or larger areas are rarely, if ever, truly disinfected. This poses an ongoing infection risk. Electrostatic spraying can spray every surface in the room, fully disinfecting it, while saving time as well.
