倾点是考察润滑油产品低温流动性能的常规技术指标之一。实验室研究发现使用滤纸过滤后,润滑油的倾点会降低,对多种润滑油产品测试后发现了这种现象的普遍性。为了解释其原因,文章从油品凝固的机理出发,提出了静电降凝的理论模型,并通过对滤纸和油品分别处理后多组实验的倾点变化,验证了该理论,同时证明,油品中的静电来源于过滤所用的滤纸。

The pour point is one of the generally technical targets evaluating the low-temperature fluidity of lubricating oil.Research found that the pour point would fall after lubricating oil is filtrated.The universal phenomenon is found by testing all sorts of lubricating oils.In order to explain the reason,the theoretical model of pour point depression of lubricating oil caused by static electricity is put forward based on the mechanism of solidification.Through the observing experiments on pour point changing after dealing with the filter paper and oil,the correctness of this theory is proved.It also shows that the static electricity comes from the filter paper.
