Abstract

The detonation of mixtures of highly dispersed PETN with sodium bicarbonate with a mass fraction of the latter up to 90% is investigated using radio interferometric method and electron-optical method NANOGATE-22 along with a method using a polyvinylidene fluoride pressure sensor. The experimental results obtained indicate the possibility of the existence of various detonation regimes in mixtures. If the mass fraction of NaHCO₃ is \(\le\) 85%, the detonation wave propagation is mainly due to shock compression. At a higher NaHCO₃ content (90%), the jets of explosion products predominantly serve as propagation agents.

碳酸氢钠轰炸PETN炸药的机理

摘要

使用无线电干涉法和电光法NANOGATE-22，以及使用聚偏二氟乙烯压力传感器的方法，研究了高度分散的PETN与碳酸氢钠（质量分数高达90％）的混合物的爆轰。获得的实验结果表明混合物中可能存在各种爆轰机制。如果NaHCO ₃的质量分数为 \（\ le \） 85％，则爆炸波的传播主要是由于冲击压缩。在较高的NaHCO ₃含量（90％）下，爆炸产物的射流主要充当繁殖剂。
