DNTF及其低共熔物对PBX可压性的影响

研究了二硝基呋咱基氧化呋咱（DNTF）、TNT、三硝基氮杂环丁烷（TNAZ）及其DNTF—TNT和DNTFTNAZ低共熔物作为添加剂，对压装PBX炸药可压性的影响。结果表明，低熔点单质炸药及其低共熔物混合物添加剂能够提高PBX的可压性；在DNTF、TNT、TNAZ3种炸药中，熔点越低，作为添加剂对PBX的可压性提高得越多；低共熔物混合物添加剂对PBX可压性的影响不仅与其熔点有关，而且与构成低共熔物混合物炸药的品种有关，其中DNTF与TNAZ形成的低共熔混合物比DNTF与TNT形成的低共熔混合物能够更好地改善PBX的压制成型性；作为增塑添加剂，适宜的质量分数为2％～3％。

The Effect of DNTF and its Eutectics on the Mouldability of PBX

The effects of 3,4-dinitrofurazanofuroxan(DNTF),TNT,1,3,3-trinitroazetidine(TNAZ) and eutectics DNTF-TNT and DNTF-TNAZ as additive agents on the mouldability of PBX were studied.The results show that the single and eutectic mixture explosives as additive agents could increase the mouldability of PBX.For single explosive additives including DNTF,TNAZ and TNT,the lower the melting point,the higher the moulding density for PBX,but for eutectic mixture explosive additives,the mouldability of PBX was effected by not only their melting points but also their components.The DNTF-TNAZ eutectic mixture additives could promote the pressing density much higher than DNTF-TNT eutectic mixture additives,and the suitable content in PBX was 2%-3%.
