Abstract Compared to the traditional field of propellants and explosives preparation molding technology, photocuring 3D printing which could realize precise control manufacturing performance, overturn concept explosives, had attracted close attention scientists all over world great progress been made in explosives. According technical characteristics application direction printing, this paper s...

We investigated the fate of explosives compounds in slurries containing fractured and weathered soil particles. Three soils were crushed with a piston to emulate detonation-induced fracturing. We used X-ray diffraction, scanning electron microscopy and gas adsorption surface area measurements to quantify the mineralogies and surfaces of the weathered and fractured soil particles. Soil batch slu...

Abstract In order to study the energy output characteristics of multi-component explosives mixed with aluminum powder and emulsified explosives, five groups containing different proportions were used for underwater explosion experiments overpressure tests in air. The experimental data show that when mass fraction increases from 0% 40%, shock wave 0.68 kJ·g -1 1.22 , which by 79.41%. Bubble incr...

This study describes the biological degradation of TNT by using induced aeration. Three plastic reactors were used. In each reactor 3 kg of soil were used. In order to increase the porosity of the soil, sawdust was added to soil. Textile wastewater treatment plant sludge was also added to soil. TNT at the concentrations of 1000 mg/kg of soil was added thereafter. Rhamnolipid biosurfactant at th...

A novel molecular descriptor index, viz., TG index, has been defined for modeling and estimation of detonation parameters of explosives. The index is simple to calculate, unique for each molecule and is applicable to the heteroatom containing species. The results of the correlation analyses of the TG index with the explosion data indicate that the TG index can be a very successful tool for pred...

When an explosive detonates or a propellant or flare burns, consumption of the energetic filler should be complete but rarely is, especially in the presence of large amounts of non-combustible materials. Herein we examine three types of perchlorate-containing devices to estimate their potential as sources of contamination in their normal mode of functioning. Road flares, rocket propellants and ...

The heat of explosion is one of the most important thermodynamic parameters of aluminized explosives. Two improvements in numerical calculations to predict the behaviour of the explosion of non-ideal aluminized explosives were completed in this work. The chemical reaction between aluminum and the C-J detonation products of high energy ingredients was determined and the equation of state for the...
