摘要:
点火方式是影响毫秒延期雷管延期时间及精度的重要因素，文中以铅丹-硅系毫秒延期雷管为基础，采用2种延期药配方平行试验，控制延期体切长等差增加，对比电点火头和导爆管2种点火方式条件下雷管延期时间，并计算延期时间标准偏差。结果表明：平行试验结果一致性好，同种配方2种点火方式下，延期时间存在差异，开始时电点火头点火的延期时间高于导爆管点火，后面则是电点火头点火的延期时间低于导爆管点火；试验切长范围内，导爆管点火时的延期精度普遍高于电点火头点火，且更加稳定。
Abstract:
The ignition method is an important factor to determine the delay time and the precision of the millisecond delay detonator. In this paper, two kinds of delay powder were used on the base of red leadsilicon millisecond delay detonator in the parallel experiments. The deference of the gauge lengths was controlled as a constant for all the delay elements used in experimental delay detonators. These detonators were then subjected to electric fusehead ignition or nonel ignition to measure the corresponding ignition delay times. The standard deviations were calculated accordingly. The results show that parallel experiments agree well with each other. The delay time difference under two ignition methods was observed for the same delay powder. A longer delay time can be observed for detonator subjected electric fusehead ignition than that subjected to nonel ignition when the gauge length of delay element is short. However, this observation will be reversed when the gauge length of delay element increased beyond to a certain value. Within the experimental gauge length range, the delay precision of detonator subjected to nonel ignition is normally higher and much more stable than that subjected to electric ignition.
