The aerosols currently on the market basically belong to the third and fourth generation products. Compared with traditional dry powder fire extinguishers, aerosol fire extinguishers have the advantages of small size, light weight, high fire extinguishing efficiency, fast fire extinguishing speed, good diffusion, explosion-proof function for initial fire, good environmental friendliness, no secondary damage to electronic equipment, and human body. Non-toxic, product safety is greatly improved.
From the historical development of the entire aerosol, we can basically see the advantages and disadvantages of product iterations.
The first generation of aerosol technology originated from military technology and was completed by researchers from Tianjin Fire Protection Research Institute.
The second-generation aerosol technology, which is collectively referred to as K-type aerosol in the industry, is derived from the explosion suppression system of the former Soviet armored vehicle, adding potassium-containing substances to the fire extinguishing agent, which greatly improves the fire extinguishing efficiency. possibility of damage.
The third and fourth generations were compiled by the predecessor Xi'an Jianrui, which is now Ji An Dun Fire Technology Co., Ltd. It adopts a new combination of strontium nitrate as the main oxidant and potassium nitrate as the auxiliary oxidant, which greatly reduces the damage of aerosol to electronic equipment while ensuring the fire extinguishing ability.
Finally, the S-type hot aerosol fire extinguishing agent was developed, which fundamentally solved the problem of secondary damage to the protection object in terms of insulation and corrosion.
