摘要：乳化液的质量指标包括稳定性、析油浓度、电导率pH值。由于乳化液在使用过程中易变质，使用周期较短，因而要努力控制好乳化液的质量指标，通过必要的检测手段及时监控其变化。文章通过测定乳化液的稳定性、析油浓度、电导率、pH值反映乳化液质量,并根据相关标准进行质量评价。探讨了乳化液的组成和主要质量指标及各指标对润滑效果有什么具体影响。如何控制乳化液质量指标,为轧机生产提供优质、清洁、润滑性能良好、具有一定工序防锈性能的乳化液,已成为一项重要的研究课题。

Abstract  The quality index of emulsion comprises its stability，condensate oil concentration, electro conductibility and pH values. While being used, the emulsion in short usage period is more likely to deteriorate. Therefore, it is essential to monitor the changes of the emulsion in time through the necessary means of detection in order to control the emulsion, i.e. control the quality index of the emulsion. By determining its stability，condensate oil concentration, electro conductibility and pH values, the paper indicates the quality of the emulsion and makes a quality assessment according to the relevant standards. It also presents the composition and main quality index of the emulsion as well as its concrete influence to the lubricating effect. It has become a valuable inclination to make research about how to control the emulsion quality index so that we can provide high-qualified and clean emulsion with great lubrication performance and certain anti-rust performance for rolling mill production.
