摘要
分析了3种微晶蜡样品的常规物性和分子碳分布、正构烃碳分布、异构烃碳分布,发现同样符合70号微晶蜡一级品标准的3个微晶蜡样品在使用性能上的差异是由于分子组成不同导致的。分子分布图峰值向较低碳数分子偏移后,蜡产品的100℃粘度有明显下降。
Physical properties,carbon number distribution,normal hydrocarbon carbon distribution and isohydro-carbon carbon distribution of three micro-wax samples were studied.The results show that the difference of service performance of three micro-wax samples which all accord with the first grade standard of 70^# micro-wax is caused by different molecular composition,after peak number of the sample in the carbon number distribution charts shifts into low carbon number molecular,viscosity of the sample decreases.
