摘要
闭口闪点是石油产品重要的安全性指标,可表示石油产品的蒸发性和判定是否混入轻馏分。比较详细地介绍了微量法检测石油产品闭口闪点的方法,并与传统的宾斯基-马丁闭口杯法进行了准确性、重复性、再现性的比较,结果表明:微量法的准确性、重复性、再现性更.好,而且微量法样品用量少、检测时间短,避免了宾斯基-马丁闭口杯法测量时的人为操作误差,提高了检测时的安全性,可以满足质检室的日常分析要求。
The closed flash point is an important safety indicator for petroleum products,which can represent the evaporation of petroleum products and determine whether they are mixed with light fractions.A detailed introduction was given to the micro method for detecting the closed flash point of petroleum products,and a comparison was made with the traditional Pensky-Martin closed cup method in terms of accuracy,repeatability,and reproducibility.The results showed that the micro method had better accuracy,repeatability,and reproducibility,and the sample amount of the micro method was small and the detection time was short,avoiding human operational errors during the Pensky-Martin closed cup method measurement and improving the safety during detection,which can meet the daily analysis requirements of the quality inspection room.
