A commercially available pyrotechnic igniter was used according to the EN 14034 and ASTM E1226a Standards study explosiveness of dispersed dusts. Its composition consists 1.2 g zirconium (40% wt.), barium peroxide (30% wt.) nitrate wt.). The energy released during combustion that amount is 5 kJ. article investigates influence aging in on its initiation parameters. In study, igniters different y...

Abstract Generally, the independently designed charge is used in traditional ejectors, where gunpowder usually fixed at its end. For long-stroke energy from combustion later period of piston movement mostly for structure expansion, and only a small part converted to actuation. The can be improved by increasing amount gunpowder, which results large instantaneous pressure chamber, thus leading bi...

The paper put forward transforming HTPB propellant into a luminescent signal agent in order to seek solution for its reuse after retirement. Considering comprehensively that propellants have similar content and pyrotechnic composition, red was designed the preparation process analysed. On basis of safe pulverization, strontium nitrate added as flame colorant they recombined with shellac binder ...

High-energy substances like effect propellant and are used in fireworks. In the process of manufacture, transportation, use, heat can easily get out control. The emulsifier polyisobutene succinimide (T152) is frequently to emulsify explosives. Given thermal safety fireworks, this paper T152 propellant. Thermogravimetric Fourier-transform infrared spectrometry differential scanning calorimetry w...
