Poster summary

Fire-extinguishing powders (FEP) are the most effective and versatile extinguishing materials which have high specific fire-extinguishing efficiency and capable to extinguish all classes of fire. In our research, the spray drying method was used for the synthesis of FEP extinguishing components: ammonium phosphates, magnesium and aluminum hydroxides. This method made it possible to obtain materials with particles having a spherical shape and a given size distribution, D(50) = 7 μm. Moreover, hydrophobic silicon dioxide as a functional additive for FEP was obtained by the sol-gel process. The ratio of components, synthesis time and amount of the hydrophobizing agent were determined to obtain superhydrophobic spherical particles with a size of 50–400 nm and a contact angle of more than 150°. The use of synthesized materials in the manufacturing of FEP provides their high flowability and efficiency of combustion processes inhibition, increases the ability to water repellency and extends the shelf life.
