摘要:
为了给单基发射药连续生产过程提供一种切药条件快速判定方法，研究了单基药溶剂质量分数对切药质量的影响及利用近红外光谱法快速检测药条溶剂的质量分数。通过对单基药样品与醇醚溶剂光谱采集及光谱分析，确定了醇醚溶剂建模波长范围为9 403.2~7 499.5 cm－1，选择一阶导数的方法对单基药样品光谱预处理，以偏最小二乘法建立醇醚溶剂质量分数的模型，模型的决定系数为0.971 2，预测平均误差小于1%，说明模型拟合效果良好，准确可靠，该模型能用于单基药切药过程药条溶剂质量分数的快速检测。经切药试验研究，药条中溶剂质量分数为20%～24%，才能保证切药的质量。近红外光谱法对药条溶剂质量分数快速检测，为单基发射药连续生产过程提供了一种切药条件快速的判定方法。
Abstract:
In order to provide an efficient method for determining the continuous production of single-base propellants, influence of solvent content on the quality of the single base propellant and the solvent content of the cartridge were detected by near infrared spectroscopy (NIR). Through the analysis of single base propellant samples with ether and ethanol spectrum acquisition and spectrum, solvent modeling wavelength range was represented as 9 403.2-7 499.5 cm－1, and first-order derivative method was selected to preliminarily treat spectra of single-base propellant sample. Partial least squares method was used to establish the model of solvent content, determination coefficient of the model is 0.971 2, and relative prediction error is less than 1%, that means the model fitting effect is good, accurate and reliable. The model could be used in cutting process of a single-base propellant for rapid detection of drug solvent content. The content of the solvent in the propellant is 20%-24%, so as to ensure the quality of the propellant. The rapid detection of the solvent content of propellant by NIR provides a rapid determination method for the continuous production of single-base propellant.
