金属清洗剂代替汽油、煤油、柴油清洗机械零件,是近年来迅速发展的一项新技术。金属清洗剂质量的优劣,主要由洗油率等技术指标确定。目前国内普遍采用重量法测定清洗剂的洗油率,但重量法存在灵敏度低和准确性差等较多问题。对于微量残留油份的测定,重量法已不能胜任。近年来国内外广泛采用荧光法测定微量油份。在此基础上,
Metal cleaning agent instead of gasoline, kerosene, diesel cleaning machinery parts, is a rapid development in recent years, a new technology. The quality of metal cleaning agents, mainly by the wash oil rate and other technical indicators to determine. Gravimetric method commonly used in the determination of detergent wash oil rate, but the gravimetric method has low sensitivity and accuracy of the more problems. For the determination of traces of residual oil, the gravimetric method has not qualified. In recent years, extensive use of fluorescence spectrometry determination of trace oil. on the basis of,
