اثر N-متیل-4- نیتروآنیلین، 2- نیترو دی فنیل آمین و دی فنیل آمین به عنوان پایدارکننده برای پیشرانه تک پایه (علمی-پژوهشی)

The explosion material due to inner pressure have structural instability and this subject special in case of compounds contain nitrate, nitro, di-azo, and azide agents, …,while show in higher temperature than normal media will be greater. thus, the compound is added as a stabilizer to the materials that are capable of reacting with the products of decomposition of the propellant and stable them. In this research, three types of powder, were produced from 98.5% of nitrocellulose, and 1.5% of stabilizer (containing diphenyl amine, 2-nitro diphenyl amine, and n-methyl para nitro aniline), and investigated by different stabilization experiments, like: Bergmann- Junk test, Differential Scanning Calorimetry analysis. Results showed stabilizer: N-methyl-4- nitro aniline in another tests in comparision with other two stabilizers not to be shown acceptable results ,but methyl violet thermal test. 2-nitrodiphenyl amine showed good results in all tests.
