Dry powder fire extinguisher
Dry powder fire extinguishers are filled with dry powder extinguishing agents. The dry powder fire extinguishing agent is a dry, easy-to-flow fine powder for fire extinguishing and consists of inorganic solid salt with extinguishing effect and a small amount of additives, which are dried, pulverized and mixed to form a fine solid powder. By covering the surface of the flame and insulating it from the air, it can no longer continue to burn, thus achieving the effect of extinguishing the fire.
Wind fire extinguisher
The wind fire extinguisher removes the third condition temperature and extinguishes the flame. The air fire extinguisher blows high-speed air to the flame at a high speed so that the surface temperature of the burning object drops rapidly. When the temperature is lower than the burning point, combustion stops. This is the principle of wind fire extinguishers.
The structure of the wind fire extinguisher is very simple, an electric motor, fan blades, ducts, batteries.
