BULLET FOR FIRE EXTINGUISHER

摘要

PURPOSE: A bullet for a fire extinguisher is provided to improve a power characteristic, a destruction characteristic and a flying characteristic appropriate for a use purpose and to increase a hit rate without using lead in a bullet core material and improving an ammunition box, a propellant and a detonator. CONSTITUTION: A bullet core material is comprised of an elastomer for improving the resilience of a bullet core in a thermoplastic polymer resin; a thermoplastic resin composition(3) added up with a plasticizer; heavy metals(4,5) having small and large powder particles to adjust the gravity of the bullet core; a biodegradable additive for naturally dissolving a polymer resin; and a bonding agent for improving the interfacial adhesiveness between the thermoplastic resin composition and the heavy metal. The bullet core material is formed into a specific shape of the bullet core.
