AI Technical Summary
Existing fire extinguishing agents have low extinguishing efficiency when extinguishing Class B fires caused by the combustion of fuel liquids such as gasoline and diesel, cannot effectively absorb toxic gases in the fire scene, and pose a hazard to the environment.
A method for preparing biomass-based aerogel fire extinguishing agent is adopted, which uses aerogel matrix, sodium lignosulfonate, phytic acid and other raw materials to prepare aerogel, and forms a hydrophobic and oleophilic biomass-based aerogel by hydrophobic modification and mixing with other components. Combined with mesoporous nano silica and modified vermiculite, it can achieve rapid fire extinguishing and toxic gas adsorption.
It enables rapid extinguishing of fuel fires, reduces the concentration of oil vapor in the combustion zone, adsorbs toxic gases, and is environmentally friendly, preventing explosions and reignition during combustion and improving rescue safety.
