Abstract: This paper presents investigations of physical properties of hydrogel (HG) based on the lightly crosslinked polymer of acrylic acid "Carbopol ETD 2020" brand under conditions of electrical and thermal modifications when exposed to alternating frequency-modulated signal (AFMS). Data on change in the hydrogel viscosity depending on the gel-forming component concentration, AFMS treatment, and temperature were obtained. It is established that the comparative heating time of modified hydrogels increases with increased concentration of the gel-forming component and under AFMS exposure for thermally modified hydrogels near the water critical point of 4 °C. The advantages of using modernized HG with respect to the traditional fire-extinguishing agent are shown. Thermophysical and rheological properties of HG obtained under electrical modification and hydraulic calculations of watering systems for above-ground vertical stock tanks (VST) of petroleum product proved the justification for their use and showed improving efficiency of installations for thermal protection of tanks storing petroleum products. The compositions of modified HG and their field of application in the nomenclature of tanks for petroleum products were determined. Practical recommendations with calculation results for the use of modified HG on existing fire extinguishing installations in tank batteries are proposed.
