PREPARATION OF TURBINE OIL VNTP-22 IN ACCORDANCE WITH STANDARD GOST 9972-2020This paper presents the results of research on the preparation of turbine oil VNTP-22 in accordance with standard GOST 9972-2020. The research showed that a mixture of 4 cSt and 8 cSt base oils (group III) is suitable for preparation; ashless rust and oxidation (R&O) additive HiTEC 2571, antioxidant additive Yalub BODPA and demulsifier DL 32 were used as additives. According to the test results, the VNTP-22 product is equivalent to technical characteristics of the reference oil sample Tp-22 and meets the requirements of standard GOST 9972-2020.The R&O HiTEC 2571 additive allows to significantly increase the antioxidant stability of the turbine oil while providing adequate corrosion protection. Additional tests, such as foaming ability, anti-wear ability, antioxidant stability of the prepared oil, also gave good results.
