油料化验分析中几个细节问题的探讨

Discussion on Several Details in Oil Products Analysis

依据相关标准,对石油成品油化验分析中存在的蒸馏测定过程中的最后一次加热的调整问题、喷射蒸发法胶质实验条件的选取问题、沸点测定中的脱脂棉问题、润滑脂工作锥入度测定中标准锥尖的位置问题、测定密度时温度计读数的有效位数问题进行了探讨,提出了相应的改进措施,为准确获得实验数据提供了保证。

According to the relevant standards,the adjustment of the last heating in the distillation process,the selection of resin experimental conditions in jet evaporation method,the absorbent cotton in boiling point determination,the position of standard cone tip in the determination of working cone penetration of grease,and the effective digit of thermometer reading in the determination of density were discussed.The corresponding improvement measures are provided to ensure the accurate acquisition of experimental data.
