Electrostatic Discharge, or ED, is a process that involves electrostatic attraction and repulsion between electrically charged particles. The concept behind electrostatic sprayers is that an electric current is applied to a surface, which attracts the charged particles on that surface. An electrostatic charge is formed at the contact point, which is generally a thin film of metal or plastic applied to the surface being worked on. Electrostatic sprayers are used to discharge potentially hazardous materials such as corrosive salts, acids, strong alkalis, solvents, metals, and synthetic fibers. They are also used in many different manufacturing applications for application in the production of finished goods, and in many service applications for equipment such as computers, television sets, and medical equipment. Because of their wide variety of uses, they are a very versatile industrial appliance.
One application of electrostatic sprayers is for biological contamination. In the early days, biological hazards were not electrostatically charged but were rather attracted by static charges due to the presence of microbes on certain types of natural or man-made surfaces. The use of an electrostatic sprayer is particularly important when dealing with such potential hazards, since it is not possible to manually clean or eliminate all microbes on any type of surface. In fact, ED technology was primarily used for biological contamination of work places, rather than in other environments, where mechanical scrubbers and other equipment would be impractical or simply not cost effective. For this reason, the installation of electrostatic discharges in such work areas as workstations, warehouses, and other similar environments has provided enormous benefits in terms of health protection and in the elimination of potential harm to employees and the environment.
Additionally, electrostatic sprayers are often used for the elimination of potential pathogens. These electrostatic devices are commonly used in the health care industry, particularly in the treatment and prevention of disease. In this sector, they are often used in combination with other types of preventive and curative measures. The use of a protective device against infectious agents presents many benefits in terms of safety, cleanliness, and efficiency. In fact, there are very few health care settings in which the application of a chemical agent alone is considered to be sufficient for the elimination of potential pathogens. However, since the early days of electrostatic disinfection, improvements have been made that have vastly improved the efficacy of such devices.
As with any type of electrostatic disinfectant or cleaning solution, potential pathogens should be eliminated using some sort of physical or chemical method. For example, a physical approach could involve the use of physical barriers, such as plastic sheeting or sealing materials. However, there are a number of factors involved in the proper use of electrostatic sprayers in the workplace, including the frequency of use, the frequency of cleaning, and the overall safety of the facility in which the device is utilized.
For example, it is important that the electrostatic sprayer be maintained in good working order. Properly-maintained sprayers are able to provide an effective means of containing infectious agents, as well as other sources of contamination. For this reason, it is necessary to check and adjust the sprayer nozzle often to ensure that it is always spraying at its maximum effectiveness. There are a number of different types of electrostatic sprayer nozzles, including:
When using a portable electrostatic sprayer in high-risk or hazardous conditions, it is important to use the right type of chemical for the job. Commonly used chemicals include: oxalic acid (such as oxalic acid, hydrochloric acid, phosphate bleach, or chlorine dioxide), or diluted sodium hypochlorite disinfectant using granular carbon. In situations where there is a greater amount of contact between potentially contaminated surfaces, a combination of these chemicals may be used. It is also possible to use an ozone generator (using ozone gel, nitrogen, or an ozone generator unit), in order to minimize the harmful effects of electrostatic discharges.
Sars-Cov-2 is a unique kind of electrostatic sprayer that was developed by a group of researchers in the early 1990s. This technology has been especially useful for infectious disease clinics and hospital settings, where many hazardous conditions, such as inhalation of infectious aerosols, are known to occur. In fact, this novel disinfection technology is currently used to prevent the spread of a number of diseases, such as Hepatitis A virus, Hepatitis B virus, and possibly the Sars-Cov-2 virus. In this type of electrostatic sprayer, a collection bag containing a dilution of a potential contaminant is placed over potentially contaminated surfaces. When charged, the positive electrical charge attracts and neutralizes any potential contaminants that come into physical contact with the collection bag.
As an alternative to the novel, single cell and electrolysis pumping ionic solvent spraying techniques, the most commonly used electrostatic techniques include the accelerated wet spraying, rapid wet spraying, and cold spray spraying. Accelerated wet spraying and rapid wet spraying are far less damaging to nonporous materials than the former and the latter are far easier to use on porous materials, especially plastics. The cold spray, however, is the best for destroying spores and infectious agents that have to be eliminated through inhalation. The only real downside to these types of electrostatic sprayer systems is that the charge generation is a little too rapid for some applications, such as those where particles or pathogens could be dislodged through physical interaction with the surface of a surface.
