Mg-Al合金爆炸特性的试验研究

Experiment research of detonation performance of Mg-Al alloy

Mg-Al合金是一种广泛运用于工业、国防等领域的化工材料。为研究其爆炸特性,对不同浓度、不同粒度下合金粉尘爆炸压力的变化规律进行了实验探究,并考察了惰性粉尘的加入对爆炸压力的影响。结果表明,Mg-Al合金粉末的爆炸压力随着浓度的增加均呈现先增大后减小的趋势;Mg-Al合金粉末的粒度越小,达到爆炸最大压力的时间越短,且压力值越大;碳酸钙粉末的加入,可以显著降低爆炸压力。

Mg-Al alloy is a chemical material widely used in industry and national defense. In order to research the explosion properties, the change discipline of blasting pressure under different concentration and practical size is explored by experiments, and so as the influence of contents of inert dust on blasting pressure. Results show that the blasting pressure of Mg-Al alloy dust increases at first then decreases with the concentration increasing. The smaller the particle size is, the earlier and larger the pressure gets to max. Inert dust can lead a significantly reduce to the max pressure.
