Influence of Composition of Dielectric Liquid Mixtures on Electrostatic Charge Tendency and Physicochemical Parameters

The paper presents research results on ECT (electrostatic charge tendency) of hexane and toluene mixtures, that is dielectric liquids of a simple chemical structure and high purity (Pro analysis). The research tests are carried out in a spinning disk system, where the factors affecting the value of the electrification current registered are a varying composition of the mixture, rotational speed and a disk diameter. In the next stage physicochemical parameters are measured in order to determine the relationship between the properties of the mixtures under study and the electrification current generated. The research results show that the ECT of the mixture depends, to a large extent, on the proper selection of particular components.
