Abstract

The invention relates to an ammonium-nitrate-type explosive explosion method and an apparatus based on shock-wave dynamic mixing. The apparatus is characterized in that: the apparatus comprises a shock wave tube and a sample fixing device; wherein the shock tube comprises an ignition device, a driving-segment charging port, an experiment-segment charging port, a first pressure sensor, a second pressure sensor, a polyethylene film and a signal fiber outlet; and the sample fixing device comprises a fixed copper circular ring, a movable copper circular ring, a fiber viewing port, a screw-socket, a signal fiber protected by a high-temperature tube, a circular ring pedestal and an experiment powder packaging bag. The apparatus helps to realize dynamic mixing in a fast reaction of a metallic nanometer powder / an ammonium-nitrate-type explosive, and not only helps to increase brisance, but also is capable of stimulating the real state of the novel ammonium-nitrate-type explosive when in the fast reaction. The apparatus has the advantages of being simple and easy to operate, low in price and reusable, and the method and the apparatus are widely applicable to the field of various explosive explosion experiments.

Description

technical field [0001] The various embodiments of the present invention relate to the technical field of explosive mechanics of energetic materials, and in particular to the explosion method and device of ammonium nitrate explosives based on shock wave dynamic mixing. Background technique [0002] Energetic materials have been widely researched and applied in various fields of national economy, especially military fields. Among various types of multi-series energetic materials, azacyclic nitramine explosives have always been the focus of research, and as representatives of azacyclic nitramines, RDX (RDX) and Octogen (HMX) are many high-performance explosives. One of the important components of explosives and advanced composite propellants, a lot of research work has been done on its combustion and explosion process both experimentally and theoretically. [0003] Since the nano-metal powder can accelerate the decomposition of energetic materials, the energetic materials can ...
