When using the clear water fire extinguisher, the slap method can be used.
Firstly, the water fire extinguisher is erected upright, the protective cap is removed, and the convex head of the top of the open bar is patted with the palm of the hand,
and the water flow will be ejected from the nozzle.
Next we will tell you the principle of this clear water fire extinguisher .
The fire extinguishing agent in the water fire extinguisher is clear water.
Water has a low viscosity at room temperature, high thermal stability, high density and high surface tension.
It is an old and widely used natural fire extinguishing agent, easy to obtain and store. It relies mainly on cooling and suffocation to extinguish fires.
Since each kilogram of water is heated from the normal temperature to the boiling point and completely vaporized, it can absorb 2593.4 KJ of heat.
Therefore, it utilizes its ability to absorb sensible heat and latent heat to exert a cooling and extinguishing effect, which is unmatched by other fire extinguishing agents. In addition, the water vapor formed by vaporization of the water is an inert gas, and the volume will expand by about 1,700 times.
During the fire extinguishing, the water vapor generated by the water vaporization will occupy the space of the combustion area, dilute the oxygen content around the combustion material, hinder the fresh air from entering the combustion zone, and greatly reduce the oxygen concentration in the combustion zone, thereby achieving the purpose of suffocating fire.
When the water is sprayed, the specific surface area of the formed water droplets and droplets will be greatly increased, enhancing the heat exchange between water and fire, thereby enhancing its cooling and suffocation.
In addition, some of the flammable and flammable liquids that are easily soluble in water can also be diluted; the water mist generated by the strong jet can cause emulsification of flammable and flammable liquids, causing rapid cooling of the liquid surface and a decrease in the velocity of flammable vapors.
They can achieve the purpose of fire fighting by this clear water fire extinguisher .
No matter what the clear water fire extinguisher is high-quality ,we also need to treat them well .
