Influence of Humidity on Burning Perfectibility of Winding Combustible Cartridge Case

Abstract:

Studied the hygroscopic properties of winding combustible cartridge case by weighing method. Investigated residue formation of cylinder materials with different water contents by nitrogen-bomb tests. The results show that the higher the relative humidity is, the greater the equilibrium moisture content of the inside-wall material is. When the relative humidity was about 90%, its absorption rate was about 4.3%. Compared with its outside wall, the inner parts have much stronger moisture absorption properties. And the gross of combustion remains reached to the minimum when the relative humidity was about 60%.
