| 摘 要： | 利用扫描电镜（SEM）和能谱仪研究了含不同钾盐的NC／TMETN推进剂熄 火表面特征,研究结果表明,有机钾盐KD使用进剂熄火表面上Cu元素的含量降低,导致Pb和Cu的复合催化作用减弱,而KNO3使推进剂熄火表面碳含量降低,铅球尺寸增大,导致催化活性组分减少,催化作用减弱;K3AlF6与铅的氧化物在推进剂熄火表面形成了PbF4,从而完全破坏了铅化物的催化作用。

| Abstract: | The quenched surface characteristics of NC/TMETN propellant with potassium salts were investigated by the scanning electron microscopy (SEM) and the LINK ISIS energy spectrum. The results showed that Cu content on the quenched surface reduced because of KD added into the NC/TMETN composition, which weak ened the cooperation between Pb and Cu. While the carbon content on the quenched surface depressed and the size of Pb ball increaied due to KNO 3, which lead the active materials to decrease and the catalysis to weaken. Because K 3AlF 6 reacted with the oxide of Pb to form PbF 4,the catalysis of Pb compound was destroyed completely. |
