compounds have received wide attention. This study focused on investigating the interaction mechanism of guanidinium-5-aminotetrazole (GA) and nitrocellulose (NC) by kinetic methods and TG-DSC-FTIR analysis. DSC and TG experiments indicated that there was a certain interaction during the pyrolysis process of NC and GA. Comparing the kinetic models of NC and peak 3 in NC-GA, it can be found that the addition

硝化纤维素(NC)的相互作用机制。
DSC和TG实验表明NC和GA在热解过程中存在一定的相互作用。对比NC和NC-GA中峰3的动力学模型可以发现,GA的添加主要影响第二步B→C中的m值和贡献,机理函数从F n变为C n ,米。TG-
