Investigation of environmentally friendly lubricants
Santrauka
Many of the lubricants used in the world today cause environmental pollution. To reduce pollution environmentally friendly lubricants should be used. The attractive base oil for environmentally friendly lubricants is vegetable oil. However it is some disadvantages like pure oxidation stability. This paper discuses the influence of thermal oxidation on physico-chemical, and environmental properties of rapeseed oil. Spectral analysis, viscosity and viscosity index represents physicochemical properties, while biodegradation in aerobic conditions evaluates environmental properties of tested oil.
