34.为什么不能用掏或吹的办法清除火雷管加强帽上的杂物?答:火雷管的结构如图8所示。它由管壳,正、副装药和加强帽三部分组成。可以做正装药(起爆药)的炸药有:二硝基重氮酚(DDNP)、雷汞、氮化铅、三硝基间苯二酚铅等。这些炸药对冲击、摩擦、震动、火焰、静电火花等特别敏感,很多国家都禁止用任何运输工具运输(加工成雷管后例外)。火雷管的加强帽下面就是敏感的起爆药,如果火雷管中有杂物而用工具掏或用嘴吹,就
34. Why can not use the method of digging or blowing clear the fire tube to enhance the debris on the cap? A: The structure of the fire detonator shown in Figure 8. It consists of shell, positive, deputy charge and strengthen the cap three parts. You can do is charge (detonating drug) explosives are: dinitro diazo phenol (DDNP), thunder mercury, lead nitride, lead trinitro resorcinol. These explosives are particularly sensitive to shocks, friction, vibration, flames, static sparks and many other countries prohibit the use of any means of transport (exception after processing into a detonator). Fire detonator to strengthen the cap below the sensitive primer, if there is a debris in the detonator with a tool to dig or mouth blowing
