Stock Office Fire Extinguisher Using Fire Extinguisher and Dry Powder

The dry powder fire extinguisher is filled with ammonium phosphate dry powder fire extinguishing agent. Dry powder fire extinguishing agent is a dry and easily flowing fine powder used for fire extinguishing. It is composed of inorganic salt with fire extinguishing effect and a small amount of additives which are dried, crushed and mixed into fine solid powder. It is a fire extinguishing agent widely used in fire fighting, and is mainly used in fire extinguishers.

The total specific surface area of quantitative dry powder is small, the mass of single particle is large, the sedimentation rate is fast, and the decomposition rate is slow when heated, resulting in its low ability to capture free radicals, so the fire extinguishing ability is limited, which limits the use range of dry powder fire extinguishing agent to a certain extent. The particle size of dry powder fire extinguishing agent is directly related to its fire extinguishing efficiency. The larger the critical particle size of the fire extinguishing component, the better the fire extinguishing effect. Therefore, it is an effective way to improve the fire extinguishing efficiency of dry powder fire extinguishing agent to prepare ultrafine fire extinguishing powder that can be uniformly dispersed and suspended in the fire space, ensure the activity of fire extinguishing component particles, and reduce the amount of fire extinguishing agent used per unit space.
