为了得到等离子体起爆电压及等离子体与不敏感含能材料接触面积对起爆响应强度的影响规律,选择典型分子类不敏感含能材料FOX-7、LLM-105和TATB,以及离子类不敏感含能材料FOX-12和HATO,以金属丝电爆炸为等离子体源,进行15、20和25 kV起爆电压及直线形(Z)和螺线形(W)金属丝形状的等离子体起爆试验,以见证板形貌及最大形变量判定含能材料的爆轰响应强度。结果表明,不同种类含能材料对等离子体的起爆响应不同,增加等离子体起爆电压可以显著增加分子类不敏感含能材料FOX-7、LLM-105和TATB的响应强度,其响应强度顺序为W/25 kV>Z/20 kV>W/20 kV;而离子类不敏感含能材料FOX-12和HATO对等离子体起爆条件没有显著规律;分子类不敏感含能材料比离子类不敏感含能材料对等离子体起爆电压和等离子体与含能材料的接触面积更敏感。 |

In order to obtain the influence rule of the plasma initiation voltage and the contact area between plasma and insensitive energetic materials on the response intensity of the insensitive energetic materials,the typical molecular insensitive energetic materials 1,1-diamino-2,2-dinitroethylene(FOX-7),2,6-diamino-3,5-dinitropyrazine-1-oxide(LLM-105)and 1,3,5-triamino- 2,4,6-trinitrobenzene(TATB)as well as ionic insensitive energetic materials N-guanylurea-dinitramide(FOX-12)and dihydroxylammonium 5,5'-bistetrazole-1,1-diolate(HATO)were selected,and a series of initiation experiments were carried out,with plasma generated by exploding bridge wire at different initiation voltages of 15,20 and 25 kV,and with straight wire (Z)and spiral wire(W).Detonation response intensity was evaluated by morphology and maximum deformation of witness plates.The results show that the initiation response are different with types of insensitive energetic materials.Increasing the plasma initiation voltage can significantly increase the response intensity of molecular insensitive energetic materials,and the order of response intensity of molecular energetic materials FOX-7,LLM-105 and TATB is W/25 kV>Z/20 kV>W/20 kV,the ionic insensitive energetic materials FOX-12 and HATO have no significant rule for plasma initiation conditions.Compared with ionic insensitive energetic materials,molecular insensitive energetic materials are more sensitive to plasma detonation voltages and contact area between plasma and insensitive energetic materials. |
