| 摘 要： | 为了研究硝酸铵粉尘的静电特性,通过模拟改性硝铵炸药连续化生产线实际生产中的气流输送装置,对气流输送过程中的改性硝酸铵粉尘进行了静电测试.从14组有效试验结果可以看出,尽管气固浓度较高,放电电压较大,但是改性硝酸铵在试验过程中并未发生反应,没有因为电极放电而出现冒烟等反应现象.结果表明,改性硝酸铵的静电火花感度E50＞2 073.6 mJ,最小静电着火能E0.01＞103.7 mJ,在模拟气流输送过程中对静电是安全的.

| Abstract: | In order to study electrostatic properties of modified ammonium nitrate dust(MAND),based on the continuous product line of modified ammonium nitrate explosive,the equipments for airflow transportation were simulated and the electrification of MAND in the airflow transportation process was detected.14 set of effective experimental data indicated that although the gas-solid concentration and the discharge voltage were slightly high, MAND were not reacted in the process of experiments,and some experimental phe... |
