添加剂和含添加剂润滑油中的锌含量是其重要的质量指标之一。目前,国内这一指标的测定,一般采用(SY2661-77)容量法,测定时必须进行较为复杂的灰化等前处理,费时较长。本文介绍的是用二甲苯-醋酸混合溶剂先将试样稀释后,再用空气-乙块火焰进行测定。由于它不需要灰化等前处理,所以实验手续比较简单,作一次平行实验,约只需50分钟,因此对添加剂和含添加剂润滑油的研究与生产都能广泛适用。 Zinc content in additives and additives Lubricants is one of its important quality indicators. At present, the domestic measurement of this indicator, the general use of (SY2661-77) volumetric method, the determination must be more complex ashing pretreatment, time-consuming. This article describes the sample is diluted with xylene - acetic acid mixed solvent, then air - B flame test. Because it does not require ashing and other pre-treatment, so the experimental procedure is relatively simple, for a parallel experiment, about only 50 minutes, so the additives and additives containing lubricants research and production can be widely applicable.
