润滑脂结构的扫描电镜观察及其制样方法的研究

Study on the Observation on the Structure of Grease by Scanning Electron Microscope and Sample Preparation Method

扫描电子显微镜(SEM)是用于观察润滑脂皂纤维结构的一种常用且有效的手段。借助扫描电镜可以观察润滑脂皂纤维的长度、形状和排列方式,进而研究润滑脂皂纤维结构与性能的关系,为提高润滑脂使用性能提供依据。本文分别从样品的导电处理、扫描电镜的操作模式和润滑脂样品的制备方法等方面,研究了用扫描电镜观察复合锂基脂样品的最佳操作方法。对于不同稠度、不同稠化剂类型的润滑脂产品,应该摸索相对适合的制样方法。

Scanning electron microscopy （SEM）is a common and effective methodwhich is used to observe soap fiber structure of grease.With the aid of SEM,the fiber length,shape and arrangement of grease can be observed,then the relationship between structure and performance of grease can be studied in order to improve the using performance of grease.The best operating method of SEM for the observation of grease was obtained from conductive sample processing,operation mode of SEM and sample preparation methods.The results showed that for grease products with different consistency and thickener types,the relative suitable sample preparation method should be groped.
