Research Progress of Polymer Fire Extinguishing Gel and Its Application in Forest Fire Prevention

[...]research has been conducted in various fields to enhance the utilization rate of water resources. [...]these materials retain moisture even under high temperature and high pressure conditions, while also exhibiting excellent stability in light, cold, heat, acid, and base environments (2) Therefore, the use of polymer fire extinguishing gel has great potential in preventing and extinguishing forest and grassland fires. 2.1 Structure From a molecular structure perspective, the fire extinguishing gel is primarily composed of a polymer 3D framework, polar waterabsorbing functional groups, and water molecules. [...]the SAP precipitates due to particle formation. Solution polymerization offers a simple and easy process, but it also presents some drawbacks, such as high viscosity, low polymerization rate, low molecular weight, and heat dissipation difficulties during the middle and late stages of polymerization. 4.2 Reversed phase suspension polymerization Reversed phase suspension polymerization is a polymerization process where the initiator is dissolved in the aqueous phase, with the solvent (oil phase) acting as the dispersing medium, and the water-soluble monomer or polymer presenting as an aqueous droplet or particle.
