常用炸药潮解的原因及一般规律

Causes and General Rule of the Common Explosive Deliquescence

潮解性并不是在任何一个相对湿度下都存在的,而是存在某一特定的相对湿度数值,当小于这一值时就没有潮解性,只有相对湿度超过这一值时,才表现出显著的吸水能力。通过计算部分炸药在20℃时的吸湿点,以及对常见炸药不同温度时水及盐的饱和蒸汽压试验,分析吸湿点与温度的关系,探索其潮解的原因及一般规律。

Deliquescence does not exist in any relative humidity conditions, but there is a certain relative humidity, there is no deliquescence when the relative humidity is less than this value, only when the relative humidity is higher than this value, it will show significant moisture absorption ability. In this paper, by calculating some explosives hygroscopic point at 20 ~C and testing the saturated vapor pressure of water and salt of the common explosives under different temperature, the relation between the hygroscopic point and the temperature was determined, and causes and general rules of the common explosive deliquescence were explored.
