Study on the composition identification method of a lubricating grease for locomotive and vehicle brake cylinders
The composition of lubricating grease greatly affects its physical properties.Due to the complex composition of lubrica-ting grease,it is very difficult to directly identify its composition.Through a series of pre-treatment methods,such as extraction,hydrolysis,extraction,and microwave digestion,various components of lubricating grease were separated.The composition of the base oil,thickener,and additive of the lubricating grease was comprehensively analyzed using gas mass spectrometry,ICP emis-sion spectroscopy,thermogravimetric analysis,and other instruments.The method was applied to the analysis of other lubricating greases with satisfactory results.
