Summary

The portable dry powder fire extinguisher is suitable for extinguishing the begining fire of flammable and combustible liquids, gas, solid class and electric equipment.

Working principle:

 1.Chemical inhibition and negative catalyze are prosuced by the reaction between the volatile decomposer of inorganic salts in dry powder and free radicals or active groups produced by fuel in the process of burning, which makes the chain reaction be interrupted of burning for fighting fire.

 2.The powder of dry powder fall on the surface of combustible substance to have chemical reaction and form a vitreous covering layer under the effect of high temperature, thereby isolating oxygen.
