航空煤油中的游离水,目前采用目视法测定。这种方法虽然简易,但误差较大。因此,我院与空军第一研究所协作,进行了粉末法和试纸法的研究。粉末法是将轻体碳酸钙为担体、玫瑰精染料为显色剂的粉末投入航空煤油样品中,若油中含有游离水,则玫瑰精染料溶解而呈粉红色。当油中水含量较高时,则粉末由粉
Free water in aviation kerosene is currently measured by visual inspection. Although this method is simple, but the error is larger. Therefore, our institute cooperated with the First Institute of Air Force and conducted research on powder method and test paper method. Powder method is light body calcium carbonate as a carrier, the rose essence dye as a developer into aviation kerosene samples, if the oil contains free water, the rose essence dye dissolved pink. When the water content of oil is high, then the powder from the powder
