Background

For a long time, people usually use a Halon fire extinguisher to extinguish fire on a fire site, but the Halon fire extinguisher is limited or forbidden in many countries due to the extremely strong destructive property of the Halon fire extinguisher to the atmospheric ozone layer. The aerosol fire extinguishing agent is used as a substitute product of a Halon fire extinguishing agent, is in the development and trial stages at home and abroad, and has great market potential. In the nineties, russia first developed an oxygen-containing solid fuel that was used to extinguish fires using smoke generated by combustion of the solid fuel, and this fire-extinguishing agent was called a hot aerosol fire-extinguishing agent. Although the fire extinguishing effect of the fire extinguishing agent is good, the temperature of the fire extinguishing agent outlet is still high after chemical and physical cooling through high-temperature reaction generated in the fire extinguishing process.
