摘要:
为评估HAE(HMX基含铝炸药)装药的易损性,设计了不同外壳涂层及包覆层导热系数的烤燃弹结构,研究了炸药装药在快速烤燃条件下的响应特性,分析了不同外壳涂层材料(有机隔热层和高分子复合涂层)与不同导热系数的包覆层材料对HAE炸药装药快速烤燃时间及响应结果的影响。结果表明,外壳涂层及包覆层导热系数基本没有改变炸药装药的响应等级(均为燃烧或药柱喷出),主要影响破膜的时间及耐烤燃时间,使其较对比配方(外壳无涂层,包覆层为硅橡胶)有不同程度的延迟;有机涂层对炸药装药烤燃响应参数的影响不明显,烤燃弹的破膜时间和耐烤燃时间分别较对比配方延迟0.06 min和0.12 min,高分子复合涂层单独使用时可有效延长炸药装药的响应参数,烤燃弹的破膜时间和耐烤燃时间分别较对比配方延迟1.17 min和2.81 min;同时采用有机涂层和空心玻璃微球(HGMs)取代硅橡胶的包覆层后,炸药装药在压力膜破碎的同时被喷出,而采用高分子复合涂层/HGMs取代硅橡胶的包覆层后,炸药装药稳定燃烧。
Abstract:
To assess the vulnerability of HAE charge (HMX-based aluminized explosive), a roast bomb structure with different thermal conductivity of external shell coating and coating layer was designed. The response properties of explosive charge under fast cook-off condition were studied. The effects of different outer shell coating materials (organic insulating layer and polymer composite coating) and coating materials with different thermal conductivity on the fast cook-off time and response results of HAE explosive charge were analyzed. The results show that thermal conductivity of external shell coating and coating layer does not change the response grade of the explosive charge (explosives are combustion or thrown out), they mainly affect the time of pressure membrane breakage and the time of cook-off resistance, it is delayed to a different extent than the comparative formulation (the outer coating is uncoated and the coating is silicone rubber). The influence of organic coating on the response parameters of explosive charge is not obvious, the film breaking time(t1) and the time of cook-off resistance (t3) of the roast bomb were delayed by 0.06 min and 0.12 min, respectively, compared with the comparative formulation,when the polymer composite coating is used alone, the response parameters of explosive charge can be effectively prolonged, the values of t1 and t3 were delayed by 1.17 min and 2.81 min, respectively, compared with the comparative formulation. When the external coating layer is an organic coating and the coating is replaced by hollow glass microspheres (HGMs), the explosive charge was ejected at the same time when the pressure membrane was broken, and the explosive charge can be burned steadily by using the external coating of polymer composite coating and the coating layer of HGMs substituted silicone rubber.
