在用润滑油性能指标的红外光谱技术分析研究

Study on Performance Index Analysis of Used Lubricating Oil by Infrared Spectrcopy Technique

润滑油在润滑系统中起着决定性的作用,为保证装备上润滑油的使用安全,对在用润滑油性能指标的监测就显得尤为重要。本文主要介绍了利用红外光谱分析技术检测在用润滑油性能指标的发展现状,分别对润滑油的粘度、总酸/碱值、氧化安定性、水分和不溶物等理化性能指标的红外光谱方法分析进行了总结。

Lubricants plays a decisive role in the lubrication system,to ensure the safety of the equipment on the use of lubricants,it is particularly important to monitor the used lubricating performance index. The current situation of infrared spectrum to detect the used lubricating performance index was introduced,and the methods by infrared spectrum to analysis the performance index of lubricating viscosity,acid / basic numbers,oxidation stability test,water,insoluble matter,and so on,were summarized,respectively.
