摘要
润滑脂的组成极大地影响其物理性能.由于润滑脂成分复杂,对润滑脂直接进行成分鉴定十分困难.通过抽提、水解、萃取、微波消解等一系列的前处理手段,对润滑脂的各种成分进行分离,结合气-质联用、ICP发射光谱、热失重等仪器对该润滑脂的基础油、稠化剂、添加剂的成分进行了全面剖析,并可将该方法用于其他润滑脂的剖析,对润滑脂的研究和质量控制具有重要的指导意义.
Abstract
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.
