In order to understand the reaction growth characteristics and its influencing factors of typical explosives after non-impact ignition, a device and method for studying the reaction growth characteristics of explosives after non-impact ignition were established. The effects of explosive composition, forming process and porosity on the reaction growth after ignition were studied by this method. The research on ZY-5 explosive shows that the change of explosive composition can significantly affect

It is considered that the bonding and combustion products of hydroxyl-butadiene system used in pouring explosive construct a space network with flame retardant function, which plays a very good role in flame retardant. Inhibition.
