STUDY OF THE INFLUENCE OF ELECTROSTATIC FIELDS ON THE CONCENTRATION OF AEROIONS AT COMPUTERIZED WORKPLACES

Abstract

The article presents the results of measurements of ion concentrations and electrostatic field strengths at computerized workplaces. A direct dependence of ion concentrations on the levels of electrostatic fields was revealed. The dependence of ion concentrations on the distance to the computer was determined. The results of field measurements show that, regardless of the permissible levels of electrostatic field intensity, the electrostatic field of the computer and other equipment significantly affects the concentration of ions. A significant factor in the electrification of surfaces is also the operator's chair and accidental friction of polymer surfaces, which are periodically carried out by the user and are inevitable for any sedentary work. The connection of aeroion concentrations with electrostatic fields is experimentally confirmed by a decrease in aeroion concentrations of the opposite sign of the electrostatic charge. As a result of research, it was established that the sign of the electrostatic charge is unpredictable. It is determined by the triboelectric effect as a result of the contact of dissimilar polymer materials that generate charge signs determined by the contact pair. That is, in the process of designing safety measures, it is necessary to determine in advance the possible degrees of electrification of polymer coatings.
