摘要：The water-shedding property and the interfacial tension of marine engine oils with various additives have been assessed and analysed in this paper. It is concluded that the weak water-shedding property was mainly due to the molecular structure and the interfacial property of sulphonate detergent, which can adsorb on the oil-water interface intensely to form a strong interfacial film and prevent coalescence of droplets. The impact of a demulsifier to the water-shedding property and the interfacial tension indicated that demulsifier improved the water-shedding property of marine engine oil in the manner of being much easy to adsorb onto the interface but formatting a flimsy interfacial film.
