【摘要】 提出了塑料导爆管轴向静电火花感度的概念、测试原理。用标准的静电感度测试仪配以一定结构的起爆针 ,建立了可用于导爆管感度测试的实验装置 ,采用升降法测出导爆管起爆所需静电能量并用它来表征导爆管的感度。用三种导爆管进行了感度测试 ,实验条件下其感度值E0 .50 分别为 0 .4 3、1.0 8、>1.94J。更多还原

【Abstract】 A new method based on Bruceton method to determine the initiation sensitivity of nonel tube is introduced. The testing instrument is composed of standard electrostatic sensitivity instrument and a needle like discharge device. The data were processed by Bruceton method and the initiation sensitivity of nonel tube can be indicated by 50% responsive point of the detonation of nonel tube to initiation energy E 0.50 . Three types of nonel tube were determined at the experimental condition. Their E 0.50 were 0.43, 1.08 and more than 1.94J respectively.更多还原
