摘要
测定了无壳弹发射药和参比火药 :9/ 7单基药 ,双基推进剂 (双芳 3和双铅 2 )在RH90 %～ 99% ,RH 75%～ 80 %和 19.5℃条件下的吸湿性。 95℃减量实验及DTA实验结果表明 ,无壳弹发射药比参比火药具有较大的吸湿性 ,而湿度对其热安定性有一定的影响。
The hygroscopicity of caseless propellant was compared with SB propellant 9/7,propellants DB3 and DB2 as reference under conditions of 90%～99% RH and 19.5 ℃,and 75%～80% RH and 19.5 ℃ . The influence of humidity on the thermal stability of the caseless propellant was examined by means of 95 ℃ mass loss test at 95 ℃. The experimental results show that the hygroscopicity of caseless propellants is higher than those of the referential samples mentioned above,and the hygroscopicity makes caseless propellants more thermally stable than the referential ones.
