摘要:
以硝基胍发射药实际生产加工过程中不同时段的药料为研究对象，采用自主研发的固体推进剂专业双料筒毛细管流变仪测试药料的流变特性，并对流变特性曲线进行拟合，获得硝基胍发射药的流变本构方程。结果表明：硝基胍发射药具有典型的假塑性流体特征；延长捏合时间有利于高分子链充分溶胀；剪切应力-剪切速率曲线采用自构函数y=Aln2x+Bln x+C时的拟合效果较好；剪切黏度-剪切速率曲线采用Williamson流变本构方程时的拟合效果好。
Abstract:
The rheological properties of nitroguanidine-based gun propellant were tested using a self-developed professional double barrel capillary rheometer at different periods during the production of nitroguanidine-based gun propellant. The rheological characteristic curve was fitted, and the rheological constitutive equation of nitroguanidine-based gun propellant was obtained. The results indicate that nitroguanidine-based gun propellant exhibits typical pseudoplastic fluid characteristics. Extending the kneading time is beneficial for the full swelling of the polymer chain.The fitting results of the shear stress-shear rate curve by the self-constructing function y=Aln2x+Bln x+C?are good. When using the Williamson
