润滑油低温流动性的研究

摘要

Low temperature fluidity of lubricating oil has an important effect on microstructure, viscosity, solidifying point and pour point. This thesis analyzes the factors that affect the low temperature fluidity of lubricating oil and puts forward relevant solving measures, including dewaxing, viscosity index improver and pour point depressant. The work provides a systematic and comprehensive basis for the use of lubricating oil at lower temperatures.%润滑油的微观结构、粘度、凝点及倾点均对低温流动性有重要的影响,本文分析了润滑油低温流动性的影响因素,提出生产脱蜡、加粘度指数改进剂及降凝剂等解决措施,为低温条件下润滑油的使用提供了较为系统、全面的参考.
