Документ Compatibility of Recycling Plastic Lubricants(2023) Grigorov, Andrey; Ponomarenko, Vitaliy; Slepuzhnikov, Yevhen; Bondarenko, Oleksandr; Artemev, Sergey; Ilinskyi, Oleksii; Bryhada, OlenaThe compatibility of recycled greases thickened with 5 % (wt.) polyethylene and polypropylene solid waste was studied. It was found that according to the values of the dropping point and adhesive properties, recycled greases, regardless of the base oil and thickener, are compatible. However, when 10 % (mass) of recycled lubricants are added to Solidol "Zh", its adhesion properties deteriorate by 300-400 rpm, due to the negative effect of the aging products of base oils on its structure, which indicates their incompatibility.Документ The problem of selecting and structuring of educational material in english when teaching students of technical specialities(Полтавський національний педагогічний університет ім. В. Г. Короленка, 2022) Ponomarenko, Natalia; Ponomarenko, Vitaliy; Neustroieva, Gelena; Timchenko, GalinaThe article deals with the scientifically substantiated methods of selecting and organizing educational material based on its didactic significance, taking into account the characteristics of perception, preservation and forgetting of educational information by students of technical specialities, the peculiarities of the educational process of higher education from the point of view of the influence of educational material on the formation of professional qualities of a future specialist.Документ Technology for Producing Components of Technological and Boiler Fuels from Polymer Raw Materials(2021) Shevchenko, Kyrylo; Grigorov, A. B.; Ponomarenko, Vitaliy; Nahliuk, Mikhail; Bondarenko, Oleksandr; Stetsiuk, Yevhen; Matukhno, VasylThe article presents a schematic diagram of obtaining the components of technological and boiler fuels from polymer raw materials represented by materials from low and high pressure polyethylene, polypropylene and polystyrene. This scheme is based on the process of non-catalytic thermal destruction of raw materials in a batch reactor and consists of a section for preparation of raw materials, a section for thermal destruction as well as the fractionation of the resulting products. The given scheme on an industrial scale, depending on the properties of the raw material, makes it possible to obtain 10-20% (mass) of the fraction - 200°C, 30-50% (mass) of the 200-360°C fraction and 20-30% (mass.) fractions (> 360°C). Among the by-products, 3.0-5.0% (mass) light hydrocarbon gases (0.5-1.0 mass %) and the coke residue are formed. According to their properties, the obtained liquid products can be used as components for the production of process and a boiler fuel or as additives to improve the low-temperature properties of commercial fuels.Документ Adhesion properties of recycling greases(2019) Grigorov, Andrey; Sytnik, Alexey; Karchakova, Valeriia; Ponomarenko, Vitaliy; Rudniev, VasylThe results of the study of the adhesion properties of recycling greases expressed in terms of the residual amount of grease that is stored on a metal plate after testing in a laboratory centrifuge are presented. It was established that the investigated samples of recycling greases in the range of the thickness of the deposition layer up to 1.0 mm, by their adhesion properties, are fully suitable for using in all types of bearings operated with a rotation speed of up to 2500 rpm. From the number of investigated grease samples, samples with a deposition layer thickness of 0.1 mm o have evidence of fairly high values of the rotational speed when the threshold value of the residual amount of grease is reached.
