“…For selected GS, the concentration of water glass can vary in the range (3)(4)(5)(6)(7)(8)(9)(10)(11)(12) wt.%, And the concentration of gelation catalysts (3.5-15) wt.%. Preliminary studies have shown that after the loss of fluidity, the foams gradually collapsed.…”

To isolate the surface of toxic liquids, it is proposed to use fast-hardening highly resistant foams. To obtain fast-hardening, highly resistant foams, the process of gel and foaming is combined. For this, solutions of sodium polysilicate and gelation catalyst are mixed. To increase the stability of the foams, it is proposed to add water-soluble polymers to the gel-forming composition. It is shown that a fast-hardening foam of the composition Na2O·2.5SiO2 (9%)+NaHCO3 (9%)+6% foaming agent +0.5% carboxymethyl cellulose with thickness reduces the mass rate of benzene evaporation by more than 5 times. It retains its insulating properties for more than 5 days. It is concluded that it is advisable to use fast-hardening highly resistant foams for the elimination of emergencies with the spill of toxic liquids.

“…Not only chemistry, but also informatics, electrotechnics, electronics, and even acoustics and ICT (information and communications technologies) are indicated as fields of scientific research in this area. Studies on the effectiveness of particular techniques and their application have been conducted for years [4][5][6][7][8][9][10][11][12][13][14][15]. A recent scientific novelty is the use of neural networks for flame detection and wireless links for communication with the extinguishing system (innovation), thanks to which-in the case of flame detection-the extinguishing system can switch on automatically.…”

Symmetry plays a key role in the processing and analysis of not only visual but also acoustic signals in various multidisciplinary areas. New innovative and environmentally friendly methods for extinguishing flames are still being sought worldwide. One of these techniques appears to be the acoustic method. A laboratory stand was built for this purpose, which was coupled with the tested prototype of a high-power acoustic extinguisher, and then the original experiments and analyses of extinguishing effectiveness were carried out. For extinguishing, waveforms with specified parameters selected symmetrically around the frequency for which the extinguisher was designed were used. The aim of this article is to present and discuss selected measurement results concerning the possibility of flame extinguishing with the use of sinusoidal acoustic waves of low frequency (below 21 Hz), as well as with the use of frequency sweeping techniques with set parameters. Such an extinguisher can be equipped with an intelligent module so that the extinguisher may be activated automatically (without human intervention) when flames are detected. The benefits of this combination as well as the importance of image processing for flame detection are also presented in this paper. This solution, with its good fire detection and fast response, may be applicable for extinguishing firebreaks in particular.
