对装药生产线高氯酸铵(AP)处理工艺进行研究。采用与现有工艺不同的射流式真空(负压)输送AP方式,经输送距离(垂直距离4.5 m,水平距离1 m)的试验测定,AP1粒度d43变小约3μm。推进剂装药试验结果显示,球形AP d43变化10μm,推进剂燃速变化约0.1 mm/s。针对AP用量多,耗费人力大,提出了AP处理的优化组合新工艺,为解决AP输送难题探索出了可行的方法。
The charge of ammonium perchlorate (AP) process was studied. The AP mode, which is different from the existing jet-type vacuum (negative pressure) technology, was adopted to measure the AP1 particle size d43 by about 3μm after the test of transport distance (vertical distance 4.5 m, horizontal distance 1 m). Propellant charge test results showed that the spherical AP d43 changes 10μm, the propellant burning rate changes about 0.1 mm / s. Aiming at the large amount of AP used and the labor-intensive manpower, this paper proposed a new optimized combination process of AP processing and explored a feasible method to solve the problem of AP transportation.
