There is given view of construction of one-step rotor-disc mixer and described work principle in this Thesis. Also given a view of additional elements construction, arranged on working bodies (discs). It is proved experimentally, that making of slots on additional work bodies (teeth) in comparison with solid additional working elements results to significant increase quality of the mixture and performance of the device. It is determined, that to create of the emulsion with certain of dispersed particles the apparatus with modified additional working elements consumes less specific power, this is due to the fact that the working medium passes through the slots, thereby creating additional highly turbulent flows, the directions of which intersect, creating zones of sharp increase and decrease in pressure, which has a positive effect on the emulsification process. In addition specific power consumption of the device with modified additional elements is less than the specific power of the device with solid additional elements, what indicates more highly energy efficiency of supposed construction of rotor-disc mixer. Also given results of experimental research, which certifies theoretical view fully.

Abstract. The article is dedicated to development of technology and hardware design of method pipeline transport reliability improving by improving the isolated coating properties modified by microwave radiation. The article describes the technology of the modification process of the coating and instrumentation production, which allows improving operational properties not only in stationary conditions in the manufacture of the insulation coating, but also during its replacement in the field.

В статье приведены результаты исследования воздействия электромагнитного излучения сверхвысокочастотного диапазона на изоляционные полимерные материалы трубопроводов изготовленных на основе поливинилхлорида и прогнозирование влияния излучения на адгезионные свойства. Показано улучшение эксплуатационных характеристик материалов, приводящее к увеличению срока службы и надежности трубопроводных систем. Разработан метод расчета изменения и распределения температур по поверхности изолируемого материала, вызванных микроволновым излучением, необходимый для определены оптимальных режимов обработки полимера. The article provides the results of the research into the high-frequency electromagnetic radiation influence on polyvinyl chloride based polymeric piping coatings as well as forecasting how radiation can affect adhesion. It also exhibits the improvement of materials efficiency leading to longer service and higher reliability of piping systems. A calculation method for temperature changes and distribution across the coated material under the influence of microwave radiation has been developed which is required to establish the most appropriate polymer treatment techniques.
