摘要

目的研究用ＧＰＣ法测定双基火药中硝化棉（ＮＣ）．方法用峰高比的方法来检验双基火药中硝化棉含氮量对定量准确度的影响，采用增大进样量等项措施克服硝化棉二重多分散性影响．结果试验证明双基火药中硝化棉含氮量对ＧＰＣ法的准确度无明显影响；增大进样量可提高其测量精度，达到使用要求．结论ＧＰＣ法测定ＮＣ含量的精度和准确度达到标准要求

Abstract

Aim\ To research the NC content in double base propellant with Gel Permeation Chromatography (GPC) method. Methods\ The rate of peak value was used to detect the effect of average nitrogen content in NC for the quantitative conclusion. The effect of double polydispersity can be overcome by adopting the feed in large amount. Results\ When the feed in large amount are adopted

the difference of average nitrogen content of NC has no evident effect for the measurement accuracy of GPC. Conclusion\ The measurement precision and accuracy about NC content with GPC can satisfy the specification of standard.
