Ultra High-Frequency Electric Installation with a Hybrid-Type Working Chamber

Abstract

Ultra-high frequency (UHF) electric installations, using the energy of UHF electromagnetic oscillations, can perform thermal UHF modification of dielectric materials and products. As a result, its properties and parameters change in an object processed in a UHF electromagnetic field faster and more uniformly than when the heat is transferred to a heated dielectric by thermal conductivity, convection, thermal radiation. The exact change in the properties and parameters of polymers of living and inanimate nature, uniform in volume and significantly in a shorter time spent in a UHF electromagnetic field, can be obtained in UHF electrical installations, and practically without heating the object as a result of the so-called non-thermal UHF modification. The paper proposes the design and design of a UHF electric installation with a hybrid-type working chamber. Such a working chamber makes it possible to simultaneously carry out non-thermal UHF modification of a polymer and thermal UHF modification of a dielectric in one installation. A UHF electric installation with a hybrid-type working chamber is cheaper. It takes up less space than two separate installations producing the same products with the same productivity.
