自然灾害发生后迅速修建救援路线是全球关注的问题。硝基甲烷(NM)是通过控制爆炸建立这种路线的拟议方法之一。然而，当使用钨来引发爆燃时，使用NM通常需要高能量的输入。在本研究中，使用通过一根细金属丝的大电流脉冲来引发纳米金属的燃烧和加热。我们发现，由于导线的电爆炸而蒸发的轻金属元素与NM中的氧发生了化学反应，当施加到轻金属线上的能量密度增加时，NM在几微秒内通过加热开始了燃烧过程。如果金属丝被部分汽化，由于选择性加热，爆燃反应在发生这种情况的点开始。用固体或液体钨加热NM不能实现瞬时NM爆燃反应。发现挥发金属元素的氧化反应加速了NM的爆燃。我们证明了铝和镁可以成功地在电火花脉冲粉碎系统中替代钨，因为它们对启动爆燃反应的能量输入要求较低。引发NM燃烧的氧化反应的热量可以通过改变轻金属丝的直径来控制。
The rapid construction of rescue routes following natural disasters is of global interest. Nitromethane (NM) is among the proposed means of creating such routes via controlled explosions. However, the use of NM typically requires a highly energetic input when tungsten is employed to initiate deflagration. In this study, a high-current pulse passing through a thin metal wire was used to initiate the deflagration and heating of NM. We found that light-metal elements vaporized by the electrical explosion of a wire chemically reacted with the oxygen in NM, and when the energy density applied to the light metal wire increased, NM began the deflagration process via heating within several microseconds. If the metal wire was partially vaporized, the deflagration reaction began at the point where this occurred because of selective heating. Heating NM with solid or liquid tungsten failed to achieve an instantaneous NM deflagration reaction. The oxidation reaction of vaporized metal elements was found to accelerate the deflagration of NM. We demonstrated that Al and Mg could successfully replace tungsten in electric-discharge impulse crushing systems, as they have lower energy-input requirements for initiating the deflagration reaction. The heat of the oxidation reaction that initiates NM deflagration can be controlled by varying the diameter of the light-metal wire.
