Electrostatic Properties and Characterization of Specific Polymeric Materials for Building Purposes

Abstract

This work analyzes the opportunities of wider characterization of the materials used in home or industrial constructions
which may get electric charge. A non-contact way (method) for electrostatic properties measurement affecting these
materials by ions with positive or negative charge is described. The method allows to measure the surface potential
dependence on time and the surface potential dependence on deposited charge. From the measured dependencies the
following set of parameters was calculated: the surface potential limiting value, the surface potential discharge rate, the
maximum deposited charge, the layer capacitance, the energy of the accumulated charge, the volume resistance, the
electric field strength and others. To verify the possibility of the proposed method for characterization of specific
building materials a series of experiments were performed in order to establish the above-mentioned parameters of
polymer, polyester, resin based varnishes, enamels, coatings and paints, polyethylene, polyurethane films, tapes and
foams. The performed experiments demonstrate the possibilities of method application for comparison of different
materials used for the same tasks or the same materials produced by different technological processes.
