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 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.
