摘要:
针对现有塑料导爆管生产过程中由于导爆药下药时易黏附在机针底部，导致机针堵塞或药粉在管内壁分布不均、爆速值不稳定的现象，本文通过增加气路装置、利用微气流吹扫药粉，抑制药粉的积聚。试验表明：微气流吹扫条件下，导爆药的下药均匀性和爆速均一性得到明显提高；药粉与导爆管内壁的黏附性亦大幅度增加，药粉脱落堆积现象减少，导爆管的使用可靠性得到提高；此外，机针经气流吹扫后表面温度降低近20 ℃，大大提高了导爆药的热安定性以及生产的本质安全性。
Abstract:
Blocking of charging needles, unevenly distribution of explosive powder on the internal wall of nonel and instability of the velocity are often caused by adhesion of explosive powder to the bottom of charging needle in the charging process. To solve such problems, gas path devices were added to prevent the accumulation of explosive powder by blowing the explosive powder using micro flow. Results show that charging uniformity and detonation velocity heterogeneity of the nonel obviously increase after the blowing of micro flow. At the same time, adhesivity of explosive powder on the internal wall of nonel increases largely, the accumulation of explosive powder reduces, and the usage reliability is improved. Moreover, the temperature of the charging needle lowers by about 20 ℃ after the micro flow blowing. Thermal stability of explosive powder and safety in the production are both enhanced.
