Abstract

The invention discloses a method for measuring reaction completeness of powdered aluminium, and the method can solve the characterized problem of dynamic reaction completeness during an aluminized explosive explosion process. In the method, based on process measurement and combined with an airtight exploder, reacting conditions of powdered aluminium are comprehensively evaluated by measuring and recording temperature and pressure schedule curves during the aluminized explosive explosion process. In comparison with the traditional explosion heat measurement method, the method aims at reaction characteristics and dynamic characteristics of the powdered aluminium. Through the method, the reaction condition of the different-specification powdered aluminium in the phase-condensed aluminized explosive with the same ratio is evaluated along with time.

Description

Technical field

[0001] The invention belongs to the technical field of explosives, and specifically relates to a measurement method for characterizing the completeness of aluminum powder reaction during the explosion of aluminum-containing explosives. The method can directly target the same formula but different aluminum powder scales during the explosion of aluminum-containing explosives. The completeness of the reaction is characterized in real time. Background technique

[0002] A lot of practice has shown that the actual energy released by aluminum-containing explosives in the explosion process is much lower than its design value, and with the continuous increase of the ratio of aluminum powder to explosives, this problem has become increasingly prominent. Analysis shows that this is mainly caused by aluminum-containing explosives. The incomplete reaction of aluminum powder in explosives is caused by the non-ideal detonation characteristics of aluminum-containing explosives. ...
