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

... the reaction state of explosive after ignition. The microstructure of combustion products is studied by scanning electron microscopy. 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.
