摘要
通过对电雷管安全电流影响因素的分析,认为在雷管生产中一定要保证混药时间和混药力度。在保证单发发火电流不超过上限前提下,尽量降低DDNP外加量,以确保安全电流合格。
By analyzing the influence factors of the safety current of electric detonator, the opinion is that in order to ensure the safety current is qualified, the mixing time and strength must be assured in the process of detonator production, and under the premise of single ignition current doesn't surpass 0.45 A, the constituent of DDNP must be decreased as much as Possible.
