2. Fire extinguishers are stored in public places or places where fires are likely to occur. They are divided into different types such as portable and cart type. Different types of fire extinguishers have different components. They are designed for different fire causes, including foam, Dry powder, halogenated alkanes, etc.
3. The extinguishing agent in the clean water fire extinguisher is clean water. Water has lower viscosity, higher thermal stability, higher density and higher surface tension at room temperature. It is an ancient and widely used natural fire extinguishing agent, easy to obtain and store.
4. It mainly relies on cooling and suffocation to extinguish fires. Because each kilogram of water is heated from room temperature to the boiling point and completely vaporized, it can absorb 2593.4KJ of heat. Therefore, it uses its own ability to absorb sensible and latent heat to play a cooling and extinguishing effect, which is unmatched by other fire extinguishing agents. In addition, the water vapor formed after the water is vaporized is an inert gas, and the volume will expand by about 1700 times.
