Abstract
The article deals with the formation of general approaches for energy efficiency provision and improvement of the performance of technological processes of polymer high-frequency electrothermy. The research was carried out on the basis of physics and chemistry of polymer materials, thermodynamics, electrical engineering and fundamentals of automated system design. Experimental studies involved the use of the control methods of heat deformations and fields. A functional diagram of automated control systems of technological processes of high-frequency electrothermy is presented. The tasks are identified that are solved at control implementation by individual technological processes of high frequency electrothermy (drying and welding of polymer parts). Control process cyclograms are specified. The principles and general approaches to the control organization of high-frequency heating of polymers are determined. They have been formed on the basis of the need to build a universal automated control system of technological processes and provision of energy efficiency, high performance of technological processes of high-frequency processing of polymers. According to the discussed approaches, it is shown that the transition to processing in the area of the maximum possible voltages of the operating capacitor of the electrothermal equipment U p provides the possibility to save up to 30-40% of energy costs and 70% of processing time.
