Automated Study of Electrophysical Properties of Polymeric and Composite Materials

Abstract

The use of secondary resources and composites in modern polymer materials would make it possible to reduce the cost and change the physical and mechanical properties of the packaging material. The use of composites to impart new properties to polymers complicates the implementation of technologies for the production of products from them, which prevents the improvement of product quality. This is due to the lack of an accumulated database and methods of predictive determination of the obtained properties of composite materials and polymers produced with the use of secondary raw materials. (Research purpose) The research purpose is testing the methodology of automated determination of electrophysical parameters of polymer and composite thermoplastic materials. (Materials and methods) A resonant method of monitoring the electrophysical parameters necessary for an energy-efficient method of high-frequency electrothermal heating of polymers has been substantiated. We selected and modified with the installation of an automated monitoring and data collection system cumeter with a working chamber from a standard cell, retrofitted with a heating system and thermal insulation. (Results and discussion) The results of the use of an automated process of control and determination of electrophysical parameters of polymer and composite materials based on polypropylene, polyethylene with a composite of titanium dioxide were presented. The method of establishing analytical dependencies for calculating the correction coefficient when calculating the effect of thermal insulation material (dielectric cardboard) and air gap in the working capacitor on the even electrophysical parameters of the polymer and composite under study was shown. (Conclusions) The possibility of conducting automated studies to determine the dielectric properties of polymer and composite materials using the developed automated control system for the process of control, transmission, processing, visualization and storage of information about the dielectric properties of ε, ε», tgδ polymer and composite materials was substantiated. The heating temperature ranges of polymer and composite materials PP H030 GP/3 TS and 1060PE were identified in automatic mode in order to organize the most energy-efficient operating modes of high-frequency electrical equipment.
