Study on a New Cleaner Emulsion Explosive Containing Common Clay

Abstract

This paper introduces a novel emulsion explosive, which has three primary advantages, namely, the ability to easily adjust various detonation properties to desired values, decrease the overall cost of civil explosive products, and minimize environmental pollution during use. Immediate and time‐related experiments are performed in order to identify changing detonation properties of these new formulas. Our results show that both common clay and hollow glass micro‐spheres (HGMs) function as thermal diluents, which indicates that for a larger quantity of these additives, the weaker are the detonation properties under the condition of our experimental ratios (HGMs: from 5 wt.% to 15 wt.%; common clay: from 0 wt.% to 20 wt.%). Furthermore, a comparison of four alternative emulsion explosive compositions reveals that the longest storage time in this study is 5 weeks with No. 3‐3, which contains 15 wt.% HGMs and 10 wt.% common clay. In addition, nonlinear attenuation is observed and explained for that period.

Influence of Titanium Powder on Detonation Characteristics and Thermal Stability of RDX‐Based Composite Explosive

“…As shown in Figure 3(b), results of specific bubble energy of five kinds of composite explosives are summarized. Compared to specific shock energy, there is a rising tendency as the concentration of titanium powder grows whenever the distance was 0.8 m or 1.2 m. It has been determined that the value of E b was only related to detonation gas products rather than the testing distance [22]. Thus, there is no doubt that the maximum of E b will be obtained at 20 %.…”
