道路渣油表面处治含油率的测定方法,以往是采用以苯作溶剂的抽提法。这种方法需要一套构造复杂的萨克斯列特抽提仪和价贵且不易买到的溶剂及其它设备。测定时,需要供水循环冷却溶剂,测定所费时间也多,每测定一次约需三小时以上,消耗溶剂300克左右。一般仅适合实验室使用,在施工和养护工地现场不便采用。最近我们试验成功了一种用煤油作溶剂的快速测定渣油表面处治含油率的方法(参加这一工作的有成圣祝,肖泽勋,王元惠等同志)。所需的试验仪具有:天平(称量100克,感量1/100克)或托盘天平一
Road residual oil surface treatment method for the determination of oil content, the past is to use benzene as solvent extraction. This method requires a complex set of Saxlett extraction apparatus and expensive and not readily available solvents and other equipment. Measurement, the need for cooling water cycle of the solvent, the determination of the time it takes more time for each measurement takes about three hours or more, consumes about 300 grams of solvent. Generally only suitable for laboratory use, construction and maintenance site inconvenient to use. Recently, we successfully tested a method for the rapid determination of oil content on the surface of residual oil using kerosene as a solvent. (Participants in this work are Saint Marys, Xiao Zexun, Wang Yuanhui and other comrades). The required tester has: balance (weighing 100 grams, the sense of volume 1/100 grams) or tray balance one
