摘要: 利用卡尔费休电量滴定法测定了PAO中的微量水含量,用润滑油清净剂浊度测定法、石油产品颜色测定法、红外光谱和热重等分析手段评价了冷冻前后PAO的理化性能,考察微量水对PAO冷冻后形成的表面现象及对冷冻前后PAO理化性能的影响。结果表明,微量水是影响PAO冷冻后外观的主要原因,但对冷冻前后PAO的理化性能基本没有影响。

Abstract: The amount of trace water in poly alpha-olefin (PAO) was measured by Karl Fischer Coulometric Titration method. The detergent turbidity method,the petroleum products color measurement, infrared, and TGA were used respectively to determine the physical and chemical properties of PAO before and after refrigeration. The frozen PAO’s interface phenomenon was analyzed. No influence on the physical and chemical properties of PAO before and after freezing was observed. The results indicate that the trace water is the main reason for the appearance of PAO after freezing.

Key words: PAO, trace water, color , turbidity
