| Abstract: |
| The Electric Spark Sensitivity of Powder Emulsion Explosives (PEE) was tested, and then the minimum Ignition Energy was calculated. At the same time, the correlation between environmental factors and operative conditions and the electrification intensity of PEE was investigated. The Maximum Electric-discharge Current and the Maximum Electric-discharge Quantity were determined, and then the Maximum Electric-discharge Energy was calculated. The voltage and the Mass Electric-charge Density in the process of PEE preparation were tested. According to the evaluation standard, the electrification safety of PEE was evaluated. The experimental results show that the PEE in production process is safe to Electric-discharge. |
