摘　　要：采用称重法研究了某卷制可燃药筒的吸湿特性。通过密闭爆发器实验,测试了在不同环境湿度下吸湿饱和的可燃药筒样品的附着性残渣和沉降性残渣大小。结果表明,可燃药筒在潮湿环境中的平衡吸湿量随环境相对湿度的增加而增大,当相对湿度为90%左右时,其含湿量接近2%,与参比发射药具有相近的吸湿特性;当相对湿度接近70%时,药筒的残渣生成量最大,燃烧最不完全。The hygroscopic properties of a rolling combustible cartridge case were studied by weighing method.The floating and sinkable residue formations of samples saturated in different humidity were tested by a closed-bomb test.The results show that the higher the relative humidity,the greater the equilibrium moisture content of the cylinder wall.Its absorption rate closes to 2%,when the relative humidity is about 90%.Compared with its inner propellants,the combustible cartridge case has a similar hygroscopicity.When the relative humidity is about 70%,the amount of combustion remains is maximum and burning perfectibility is worst.
