摘要
利用高压差示扫描量热仪 (PDSC)研究了不同钾盐与三羟甲基乙烷三硝酸酯 (TMETN )和燃烧催化剂在热分解过程中的相互作用。热分析数据表明 ,钾盐与TMETN和燃烧催化剂Pb Cu CB之间存在着明显的相互作用。在三种钾盐中 ,K3AlF6对催化剂Φ Pb分解出活性组分PbO有破坏作用 。
The pressure differential scanning calorimetry (PDSC) was used to an investigation of the interaction of potassium salt flame suppressors with trimethylotethane reinitiate (TMETN) and burning catalyst used in NC/TMETN insensitive propellants during thermal decomposition. The data from thermal analyses show that there is an obvious interaction during thermal decomposition of the mixtures of potassium salt with Pb Cu CB catalyst and TMETN. Among three kinds of potassium salts, K 3AlF 6 has a destructive action for catalyst lead phthalate (Φ Pb) decomposing into active component PbO. This may be one of the reasons that K 3AlF 6 make the propellant plateau effect disappear.
