The Effective Disinfection of Electrostatic Spray

This cleaning method atomizes cleaning solutions to produce an electrically charged spray able to wrap around surfaces of all types for an even coat. As a chemical exits the electrostatic sprayer, it’s given a positive or negative charge that is attracted to available or negative or positive surfaces. The spray attaches to and collects positively or negatively charged unwanted particles, which are then removed from the environment with a specially designed apparatus. Surfaces that are already covered in the cleaning solution will repel the spray, making the method extremely efficient.

Q . Main Question - Does the Electrostatic power output need (+ ) Positive ) or (-) Negative of Electrostatic Sprayer ?


It depends on your environment.

for example, one internal area may have 34 % neutral (uncharged) 33 % positive 33 % negative surface area.

Triboelectric Series

When two materials contact and separate, the polarity and magnitude of the charge are indicated by the materials’ positions in a triboelectric series. The triboelectric series tables show how charges are generated on various materials. When two materials contact and separate, the one nearer the top of the series takes on a positive charge, the other a negative charge. Materials further apart on the table typically generate a higher charge than ones closer together. These tables, however, should only be used as a general guide because there are many variables involved that cannot be controlled well enough to ensure repeatability. A typical triboelectric series is shown in below table.

Virtually all materials, including water and dirt particles in the air, can be triboelectrically charged. How much charge is generated, where that charge goes, and how quickly, are functions of the materials’ physical, chemical and electrical characteristics.

Q1 .How does electrostatic effect and spray work ?


The electrostatic spray gives objects an even, 360-degree coating made possible by the negative charge of the sprayed solution as it exits the tool’s nozzle and the positive charge of the surfaces it reaches. It effectively atomizes cleaning solutions in this way, using electrostatics to attach to and wrap around harmful microorganisms and remove them from surfaces, including those that are difficult to reach. .

Q2. How does coverage of electrostatic spray ?


Q3. Does electrostatics work only when spraying metal object ?


No, nearly any piece can be sprayed electrostatically. If the electrostatic charge droplets “sees” a conductive grounded surface it will be attracted to it.

Q4. Why should I choose an electrostatic sprayer over a conventional sprayer ?


Although an electrostatic sprayer may cost more, it has many advantages over a conventional sprayer. An electrostatic sprayer has a very high transfer efficiency (60-80%) which results in a lower disinfectant cost, Manpower cost , virus cross-infection rate, and fast to disinfection large area.

Q5. What are the benefits of electrostatic disinfection?


The Benefits of Electrostatic Disinfecting

Electrostatic disinfection is an innovative method that saves time, energy and costs across the board because it presents a more efficient alternative to traditional cleaning techniques and cleaning solution applications. Below are some of the many benefits of using an electrostatic system.
Reduces the time it takes to cover and disinfect all surfaces and hard-to-reach places by 50% compared to conventional methods

  •    Improves infection control and the spread of viruses such as influenza,coronavirus, MRSA, HIV, and many others
  •    Applies chemicals in a more efficient, uniform and controlled manner, eliminating the dangers of     overuse and reducing the number        of chemicals used and waste produced
  •    Prevents costly financial burdens associated with contagious healthcare infections
  •    Avoids cross-contamination and the movement of bacteria from one surface to another
  •    Saves chemical solution costs and those associated with long-term cleaning efforts

Q6. Where can electrostatic disinfection be used ?


You can use electrostatic disinfection cleaning methods on many surfaces and in many facility types. This cleaning technique is safe to use

  • Schools
  • Car
  • Bus
  • Hospital
  • Healthcare
  • Gym
  • Medical office
  • Dental office
  • Assisted living facility
  • Hotel
  • Government Buildings
  • First Aide, Fire Department & Police Stations
  • Municipal Buildings
  • Homes

and countless other spaces that require a more complete clean.

Q7. What are the benefits of continued use ?


Electrostatic droplets cleaning kills germs, bacteria and viruses from surfaces and lasts for a while. However, it won’t continuously prevent covered surfaces from becoming re-infected. Some spaces that sees higher traffic and use, such as hospitals and schools, will benefit more from continued or regular use of electrostatic disinfection.

Reduce virus live on surfaces of complex structures

Q8. How big size can the electrostatically charged droplets from OTSON atomization nozzles ?

Ans.  Adjustable droplet size from 6 ~ 120 μ

It will depend on many factors  when you operate the  electrostatic sprayer .

  1. Room temperature
  2. Enviorment humidity
  3. Spray distance and angle from the electrostatic sprayer to object
  4. Electrostatic power voltage and current 
  5. Winds direction
  6. Air pressure of electrostatic sprayer
  7. Disinfectant viscosity
  8. Indoor or outdoor
  9. Trigger gap of the electrostatic sprayer

Q9. Can disinfectant be sprayed electrostatically ?


Yes. waterborne disinfectants are the most conductive made. This makes them ideal for electrostatic applications. However, when spraying waterborne disinfectants electrostatically, the charge will be carried back to the fluid-supply system, Therefore, spraying waterborne disinfectants electrostatically requires isolating the disinfectant supply system from no contact with people.
