The fire extinguishing mechanism of fire extinguishing gas is one or several of the four elements of eliminating combustion. K-type aerosol fire extinguishing technology, also known as potash fire extinguishing technology, is the second phase of the development of aerosol fire extinguishing technology, beginning in the Soviet Union in the mid-1960s. China started late in this respect, beginning in the early 1990s. The first generation of products was successfully developed by Beijing Institute of Technology. The aerosol generator mainly uses potassium nitrate as the main oxidant. The fire extinguishing efficiency is high, but because it contains a large amount of potassium ions, it is easy to absorb moisture, forming a yellowish sticky and strong alkaline conductive liquid film, which is very damaging to electronic equipment, so the K-type aerosol is automatically Fire extinguishing devices should not be used in electronic equipment, precision instruments and cultural relics archives.
The cabinet type ultra-fine dry powder fire extinguishing device cannot be designed as a combined distribution form for fire protection. Yangquan explosion-proof sound and light alarm installation

The four elements of combustion: combustibles, oxidants, temperatures, and uninhibited chain reactions. This is a new fire-fighting technology different from the past. It has both smoke and fog. It has both fine solid particles and an aerosol material formed by water vapor and N2 and CO2 fire extinguishing gas. Aerosol fire extinguishing technology is a new type of fire extinguishing technology developed on the basis of military pyrotechnics. In the 1960s, the oil tank smoke fire control technology studied by the Fire Research Institute was the earliest aerosol fire extinguishing technology. At that time, this new fire extinguishing technology did not attract widespread attention.
At present, some design institutes misunderstand the cabinet type ultra-fine dry powder fire extinguishing device, or hand it over to the production company to design a plan, and mix the cabinet fire extinguishing device with the dry powder fire extinguishing system, especially in the fire protection application of the chemical enterprise, a cabinet The fire extinguishing device adopts a combined distribution form to protect multiple fireproof units, and even three or four cabinet fire extinguishing devices are connected in series to become a large system, disregarding fire protection products and design and construction standards, and daring! Such design and construction, once a fire is likely to cause a major accident, designers, product providers, builders are difficult to take their responsibility! !
