摘要
研究了采用低场脉冲核磁共振(NMR)测定二醋酸纤维素丝束油剂的新方法,给出NMR法测定二醋酸纤维素丝束油剂含量的标准曲线。同时对 NMR法测量二醋酸纤维素丝束油剂不确定度进行了评估。结果表明,NMR法具有分析速度快、无污染、无损伤和准确度高的优点,适合于二醋酸纤维素丝束油剂的分析。
A new method of low-field pulsed nuclear magnetic resonance (NMR) spectroscopy for the determination of spin finish in cellulose acetate tow was investigated. Five standards for the establishment of working cusve were standardized by Soxhlet extraction with the spin finish content in range of 0.68%~1.73%, uncertainty of the determination was assessed. The method is suitable for the routine analysis of spin finish in cellulose acetate tow with the advantage of non-pollution and non-damage.
