DOI: 10.1016/j.firesaf.2020.103148
Abstract: Abstract Ultra-fine dry chemicals, as an effective fire suppressant, may have higher fire extinguishing efficiency and the ability to inhibit pool fires re-ignition after oil-repellent treatment. Thus, we used two surfactants, i.e. POTS (1H,1H,2H,2H-perfluorooctyltrimethoxysilane) and… read more here.
