Study on explosion risk of typical high-concentration hydrogen peroxide under shock wave and thermal stimulation
To investigate the explosion risk of propellant-grade hydrogen peroxide and how various concentrations affect this hazard,hydrogen peroxide samples with mass concentrations of 91％,95％,and 98％respond to shock wave and thermal stimulation under high containment were tested using UN gap,koenen,and sympathetic detonation tests.The results show that under a strong shock wave impact of about 20 GPa,the perforation diameters in the verification plates are 68 mm,74 mm and 76 mm for hydrogen peroxide concentrations of 91％,95％and 98％respectively.All tested hydrogen peroxide concentrations exhibit overall explosive hazards,and the higher the concentration,the stronger the ability to propagation detonation.At a weaker shock wave stimulation(around 2 GPa),none of the hydrogen peroxide concentrations caused perforation in the verification plates,suggesting that initiation capacity is critical to the compound's explosivity.During the Koenen test,an increase in the critical explosion diameter,which was measured at 1.0 mm,2.0 mm and 2.5 mm,respectively,corresponding to the hydrogen peroxide concentrations rising from 91％to 95％,and finally to 98％was observed.Consistent findings across both tests underscore the significant explosion risk associated with high-concentration hydrogen peroxide.The sympathetic detonation test reveals that with increasing detonation wave intensity,the reactivity of the 98％hydrogen peroxide sample heightens despite a negative outcome.
