Influence of Two Preparation Methods on Rheological Properties of Lithium Grease

作者：He Yifeng

摘要：The dropping point,cone penetration,corrosion,oil separation rate and oxidation stability of lithium grease prepared by two different processes at room temperature and high temperature were measured.The rheological properties of the samples were studied and analyzed with the microstructure of soap fiber.The results show that the content of thickener used in grease prepared by the room temperature method is higher in order to obtain the same consistency.The dropping point and evaporation loss of grease samples prepared by two processes are similar,and the oil separation rate of the lubricating grease prepared by the room temperature method is smaller.The preparation process has a great influence on the rheological properties of grease,and the higher content of thickener is beneficial to improving the rheological properties of grease.
