Fire extinguishing principle
Water-based fire extinguisher belongs to physical fire extinguishing mechanism. The agent can form and expand a thin water film on the surface of combustible materials, which can isolate combustible materials from air and realize fire extinguishing. Through the atomizing nozzle, fine water mist is sprayed, which spreads over the fire site and evaporates heat, so as to quickly reduce the temperature of the fire site, and at the same time reduce the oxygen concentration in the air in the combustion zone to prevent re-ignition. Good re-ignition resistance is an incomparable advantage of water-based fire extinguishers.

There are two certification codes at the bottle body and pendant, and these two codes must be consistent.
