石油沥青闪点测定方法的考察

通过对比国内四个知名单位对四个沥青试样闪点的测定结果，发现沥青闪点测定误差较大。通过对比不同沥青试样的闪点高低及其模拟蒸馏数据，发现沥青闪点高低与试样中轻组分含量有较好的一致性，即沥青中轻组分含量越高其闪点越低。同时，分析了可能影响沥青闪点测定结果的因素。

Investigations on Flash Point Determination Method of Petroleum Asphalt

It was discovered that the determining error of flash point of asphalt exceeded the specified requirements in determination method by analyzing the determining results of 4 representative asphalt samples measured in 4 well - known units.The asphalt with higher component had higher flash point by comparing the datums of flash point and simulating distillation.At the same time,the factors that maybe affected the results in determining flash point of asphalt were analyzed,and the old methods had no detailed provisions for flash point determination of asphalt and should be revised.
