Abstract

Electrostatically charged COVID-19 disinfectant spray coverage on a cylinder

Highlights

  • Electrostatic sprayers and nozzles have been researched and manufactured for several decades for various applications including agricultural [1], lubrication [2] [3], and combustion [4], among other applications

  • Electrostatic sprayers are a popular choice for disinfectant formulation spraying with the desire to spray coat all surfaces of complex items like hand rails, chairs, desks, door knobs, etc

  • PathoCide material is a hypochlorous acid solution composed of softened water and 165-200 ppm of Hypochlorous Acid (0.0165-0.02%); PathoCide contains no bleach, phosphates, ammonia, or petrochemicals, some of which may be found in other disinfectant materials

Summary

Introduction

Electrostatic sprayers and nozzles have been researched and manufactured for several decades for various applications including agricultural [1], lubrication [2] [3], and combustion [4], among other applications. Electrostatic sprayers are a popular choice for disinfectant formulation spraying with the desire to spray coat all surfaces of complex items like hand rails, chairs, desks, door knobs, etc. The spray produced by a traditional nozzle impacts the surfaces it comes directly in contact with but potentially excludes hard to reach surfaces leaving them untreated (ex: underside of a hand rail). As of mid-March 2021, the Johns Hopkins University of Medicine Coronavirus Resource Center [5] reports that the SARS-CoV-2 virus has caused over 120 million infections and 2.6 million fatalities worldwide. Spraying of disinfectants is one of several important tools in preventing the spread of this virus in public spaces such as schools, offices, and medical facilities; as well as future disinfecting needs in order prevent infectious public spaces and surfaces
