Ask about the fire extinguisher on the train.

Portable water mist fire extinguisher is a new fire extinguisher developed in recent years. Because of its wide range of fire extinguishing types and good fire extinguishing effect, it has become one of the main products to replace halon fire extinguishers. This introduction mainly includes MSWZ3S and MSWZ6 portable water mist fire extinguishers. The extinguishing mechanism of the fire extinguisher is 1. Because the droplets are very small and the specific surface area is large, the water vapor generated by the evaporation of the droplets absorbs a lot of heat, which makes the ambient temperature around the fire drop rapidly. 2. A large amount of water vapor generated by water mist evaporation expands rapidly, which reduces the oxygen concentration around the fire and plays a role in isolating oxygen. 3. Atomization flow directly affects the emulsification, wetting and cooling of combustion products. 4. Water mist surrounds other fuels in the protected area to prevent radiant heat from radiating to nearby combustibles. 5. Because the water mist vapor enters the fire, it dilutes the combustible gas and hinders the combustion. Fire extinguishing characteristics: 1, clean and environment-friendly: due to the use of efficient and flame-retardant water-based fire extinguishing agent, it is non-toxic, tasteless, dust-free and other residues during fire extinguishing, which will not cause secondary pollution to the environment and destroy the atmospheric ozone layer, and is a very good environmental protection product. 2. Safe and reliable: adopting patented atomizing nozzle technology (patent number: ZL 02 2 92747). 6) The water mist droplets sprayed by the water mist fire extinguisher are extremely fine, and the electrical insulation performance is good, up to 36KV, which ensures the safety of the fire extinguisher users in fire extinguishing or electrical equipment fire.
