Abstract: 

This paper presents a detailed overview of the topic concerning the oil-filling of polymeric materials for further research of the oil-filling methods. Since the production of polymer products is one of the innovative sectors to which the modern industry is showing increasing interest, therefore, the creation of plastics with the necessary properties is an urgent task. According to the existing methods of oil-filling of polymer and composite antifriction materials, the methods of adding oil directly into the polymer solution and keeping it in oil under different conditions are considered. For heating and drying, electric oscillations of industrial frequency (inductive heating), radio waves of high and ultrahigh frequencies (dielectric heating) and infrared radiation (infrared heating) are mainly used. It is known that the most effective way of heating polymers is dielectric heating. In this regard, in order to carry out experimental studies on thermal vacuum oil-filling, the authors upgraded the experimental plant, which was based on industrial equipment of HF-processing, touched upon the basics and theory of heating welding and related processes. Under certain processing conditions, the interrelation of the anode current with the electrophysical parameters of the polymer material changed during the processing on the basis of the high-frequency heating equation was justified and determined. In the course of the review the advantages and disadvantages of the existing methods of oil-filling were determined, the purpose and objectives of further research were defined.
