ADN与硝胺氧化剂的相互作用

Interaction of ADN with nitrate oxidizer

用高压差示扫描量热法(PDSC)和热重-微商热重法(TG-DTG),研究了高能氧化剂ADN(二硝酰胺铵)的热分解及其与HMX和RDX的相互作用。结果表明,ADN与HMX和RDX之间存在着强烈的相互作用。因部分HMX溶于熔融的ADN中,而参与了ADN组分的分解,ADN的放热分解峰温因压力升高而提高,而HMX产生了双分解峰。大量的RDX因ADN的熔融而提前液化与ADN一起分解,因ADN气相产物的抑制作用,使混合体系中RDX组分常压下的分解峰温后移,而RDX自身分解气相产物的催化作用,使其高压下的分解峰温前移。

Thermal decomposition of ADN as well as the interaction of ADN, HMX ADN RDX were investigated by means of PDSC ADN TG-DTG. The results show that there exists strong interaction among ADN, HMX ADN RDX. Because partial HMX dissolved into the molten ADN takes part in decomposition of ADN, the exothermic decomposition peak temperature of ADN increases with the increase of pressure while HMX appears double decomposition peak. A large amount of RDX is liquefied in advance due to molten ADN , then decomposes together with ADN . The decomposition peak temperature of RDX in the mixture system at normal pressure would shift rearward because of inhibition function of gaseous products from ADN, while the decomposition peak temperature of RDX at high pressure would shift forward because of catalytic effect of gaseous products from RDX decomposition.
