结果表明:随着浓度的增大,胶原溶液的弹性模量(G′)、粘性模量(G″)和复数黏度(η*)都提高,并且出现假固态行为,当胶原溶液浓度大于0。
Based on the problems of low viscosity index and the acidity increasing in the lubricating base oil,it has been found that the unstable quality of the crude oil was the root cause to effect on the quality of the base oil by analysis for long time;the low viscosity index and the higher acidity were resulted from the low paraffinicity and the high content of aromatics,cyclane.
