Application of a New Cleaner Emulsion‐Explosive Formula: Cu/Al Parallel Plates Explosive Welding

“…Materials which are used to prepare the new formula are all commercially available or can be easily sourced.

And purchased from the Minnesota Mining and Manufacturing Corporation of USA, we use hollow glass micro-spheres (HGMs, as shown in Figure 3(a)) as the sensitizers, whose average size, density and softening temperature are about 100 mm, 0.14 g · cm À3 and 600 8C, respectively.…”

Study on a New Cleaner Emulsion Explosive Containing Common Clay

“…Materials which are used to prepare the new emulsion explosive are all commercially available or can be easily sourced. The emulsion matrix, which has a density of about 1.45 g cm À3 , is obtained from the Shuntai Chemical Corporation of Huainan, and its chemical composition is listed in Table 1 [22], where C 14 H 44 O 6 is the emulsifier used in the emulsion matrix. For the sensitizers, we used HGMs, which are usually extracted from the waste products of cogeneration plants, as seen in Figure 1(a), using the tungsten filament scanning electron microscope (machine model: EVO/ MA15).…”

The Effect of the Hydrogen Containing Material TiH2on the Detonation Characteristics of Emulsion Explosives

“…In the early-stage, the MgH 2 powders were added to emulsion explosives as chemical sensitizers, and they would react with the emulsion matrix to produce gas bubbles to sensitize the emulsion matrix. The experiments results showed that MgH 2 powders could improve the explosion power [9,10] and the pressure-resisting ability [11][12][13] of emulsion explosives remarkably. But MgH 2 sensitized emulsion explosives may also have problems of foaming and safety for the hydrogen bubbles.…”

“…In our previous research, we developed a new kind of high-power emulsion explosives sensitized by hydrogen containing material MgH 2 [9][10][11][12][13]. In the early-stage, the MgH 2 powders were added to emulsion explosives as chemical sensitizers, and they would react with the emulsion matrix to produce gas bubbles to sensitize the emulsion matrix.…”
