Popis: | 1. Compared with the similar foreign oils, turbo-oil-35 and turbo-oil-300, synthetic oils VNII NP-7 and VNII NP-50-1-4F are less hydrolytically stable, because of which the quality of VNII NP-7 and VNII NP-50-1-4F oils is appreciably reduced upon absorption of moisture from the air. To improve the hydrolytic stability of VNII NP-7 and VNII NP-1-50-4F oils, it is necessary to seek out anti-hydrolysis additives to them. 2. MN-7.5 oil, which is fundamentally a mineral oil, is more stable hydrolytically, and therefore corrosion of a copper plate is slight and the acid number increased only slightly. |
