摘要
为研究造型流动性对分步压装工艺适应性及其装药安全性的影响,测量了不同配方造型粉的流散性和堆积密度,通过分步压装工艺试验,研究炸药的流动性对分步压装工艺及其安全性的影响。结果显示,炸药的流散性在一定范围内才能适合分步压装工艺,降低炸药的流散性,可提高局部装药密度,但增加了径向密度差,降低了装药过程的安全性。在流散性适宜的条件下,分步压装装药密度随堆积密度的增加而增加。
In order to research the effect of molding powder flow on technique adaptability and charge safety of step-press-loading, the flow and packing density of different powder have been measured. Through the experiment of step-press-loading charge technique, the results show that the flow of explosive during proper area can adapt to technique of step-press-loading charge techniques. By reducing flow of explosive, explosive loading density can be increased locally, but radial density uniformity and loading safety become worse. Having moderate flow, loading density of step-press-loading charge can enhanced with the increase in packing density of explosive.
