摘要
本文研究了废弃军用火炸药的再利用技术。主要内容包括,废弃发射药SF-3和高能炸药RDX制造球形小粒药;废弃单基发射药制备灌注型炸药和粉状低爆速炸药。
     废弃发射药SF-3经溶剂溶解后,根据产品性能要求决定是否加入增能物质RDX,再通过球形药的制药工艺加工成小粒药,以满足不同的民用或军用需求;文中研究了球形药制备过程中各种因素对小粒药产品质量的影响,该工艺成功通过工厂生产扩试。
     论文对所制备球形药的燃烧机理提出了合理的解释。为提高球形小粒药燃烧的稳定性,创造性地采用了炭黑替代传统的石墨对球形小粒药进行光泽,并对其原理和性能进行了解释和分析。重点测试了文中所制备的小粒药在射钉枪装药中的弹道性能,两种小粒药分别能满足中高和低能量的射钉弹的装药要求。
     废弃单基发射药经氧化剂胶液灌注后,制成性能稳定的廉价灌注型炸药。利用聚丙烯酰胺凝胶研制出了一种柔性灌注型炸药;筛选出一种新的廉价胶液用于制备刚性灌注型炸药。所研制的两种灌注型炸药均有密度高(1.51~1.61g/cm~3)、抗水、爆速较高等特点。
     废弃单基发射药通过特殊工艺制成粉状低爆速炸药。论文对其爆炸机理和震源机理进行了研究,提出了相应的理论计算方法。测试并分析了该低爆速炸药在石油勘探中的应用效果。结果表明,该炸药能够较大幅度地提高地震勘探的分辨率。
This dissertation studies on reclaimable technologies of obsolete military explosives and propellants, focusing on preparation of small size spheric propellants from obsolete propellants (SF-3) and obsolete high energy explosives (RDX), and preparation of perfusion explosives and powdery explosives with low detonation velocity from obsolete single base propellants.
    In order to meet the different demands of the civilian and military use, it may be necessary to add various amounts of additional energetic material (RDX) into small size spheric propellants after dissolving obsolete propellants (SF-3) in an appropriate solvent. The pilotscale experiments have been successfully carried out in the factory.
    The combustion mechanism of spheric propellants obtained is discussed reasonably. To improve the combustion stability of small size spheric propellants, carbon black is introduced to polish the propellants instead of traditional graphite, and the combustion principle and properties of the polished propellants are discussed as well. The ballistic performance of powder actuated tool bullets, in which charged with 2 kinds of prepared propellants is tested, and the results show that the propellants obtained can fit the charge requirement of both mid-high and low energy actuated tool applications.
    By adding oxidants and glue solutions into the obsolete single base propellants, the reliable and low-cost perfusion explosives are prepared. The soft perfusion explosives and the rigid perfusion explosives are prepared by utilizing PAM gel and a new low-cost glue respectively, having the excellent properties of high density(1.51~ 1.61g/cm3), waterproofness, high detonation speeds and etc.
    By means of special techniques, the powdery explosives with low detonation speed are prepared from waste single base propellants. Their detonation and hypocenter mechanism are studied in this thesis. Theoretical calculating methods for the
    
    
    
    explosives are put forward, and their application to rock oil prospecting is tested and analyzed in this paper as well. The results show that the low detonation velocity hypocenter explosive can greatly improve the resolution of the earth-shock prospecting.
