摘要
用水悬浮分散包覆工艺制备了ε-HNIW造型粉,利用FT-IR及SEM和DSC对其进行了表征。结果表明,包覆剂Estane可有效包覆ε-HNIW,包覆表面光滑且棱角减少;Estane与ε-HNIW的相容性为1级;与ε-HNIW原料相比,包覆样品的撞击感度和摩擦感度均有所降低,特性落高H50由17cm升至44cm,摩擦爆炸概率P由100%降至68%;包覆后ε-HNIW的爆速为8923m/s,是一种新型高能钝感传爆药。
In order to develop a new high-performed, low-sensitive booster explosive, molding powder of ε-HNIW was obtained by self-improved water slurry coating technology and was characterized by FT-IR and SEM. The results indicate that Estane is effective for coating ε-HNIW, the coated surface is smooth and the angularity is reduced. The results of DSC show that the Estane-ε-HNIW mixture have good compatibility with grade one. Compared with raw ε-HNIW, the impact sensitivity and the friction sensitivity of coated samples all decreased to some extent, the 50% drop height of impact sensitivity （H50） of ε-HNIW increases from 17cm to 44cm and explosion probability P decreases from 100% to 68%, the detonation velocity of coated ε-HNIW is 8 923m/s. It is a new high-performed and low-sensitive booster explosive.
