Theory of dry powder fire extinguisher:
Using carbon dioxide gas and nitrogen gas as power to eject dry powder from the cylinder. Then the volatile decomposition products of inorganic salts in the dry powder have chemical inhibition and negative catalysis with the free radicals or active groups produced by the fuel during the combustion process, so that the chain reaction of combustion is interrupted and the fire is extinguished. The other is that the powder of dry powder falls outside the surface of combustibles, which causes chemical reaction and forms a glass like covering layer under the action of high temperature, so as to isolate oxygen and suffocate the fire.
