Abstract:

Purpose. The rationale for the use of environmentally acceptable polymer surfactants of the guanidine series to increase the fire extinguishing efficiency of water when extinguishing fires in natural ecosystems.

Methodology. Studies on the criteria for the effectiveness of aqueous solutions of polymer surface active agents of the guanidine series in quenching model fire 1A. Field tests of aqueous solutions of guanidine polymers in a stream with a high jet velocity were carried out using a water fire extinguisher VVSH-9 (produced by Makiivka Plant “Fakel” JSC).

Findings. It has been established that the addition of small concentrations of solutions of polymer surfactants of the guanidine series to water leads to an increase in the range of the jet supply by 20–30 % using a water extinguisher VVSH-9; accelerating the supply of charge of the VVSH-9 fire extinguisher by 20–22 %; reducing the time of extinguishing the quenching model fire 1A by 15–20 %; increasing fire extinguishing efficiency of water by 1.98–2.23 times. It has been experimentally established that the use of a 6 % SFPM foaming agent solution makes it possible to extinguish quenching model fire 2A with a total area of 9.36 m2, and the use of polyhexamethylene guanidine urea phosphate solution makes it possible to extinguish a quenching model fire 3A with a total area of 13.89 m2. The fire extinguishing ability of the solutions of polyhexamethylene guanidine urea and SFPM foaming agents has been calculated, which is 0.55 and 0.93 kg/m3, accordingly. It is shown that the investigated solutions of guanidine polymers have a higher fire extinguishing efficiency compared to the SFPM foaming agent under these technological conditions, which is possibly associated with a decrease in energy dissipation and loss of friction of the turbulent flow.

Originality. The obtained results indicate a significant improvement in the fire extinguishing properties of the studied aqueous solutions of guanidine polymers compared to water. This is directly related to the improvement in the fluidity of aqueous solutions of polyhexamethylene guanidine salts in the studied range of concentrations, which proves that polymer features hydrodynamic activity and the ability to reduce the hydrodynamic resistance of water, as a result of which an increase capacity of pipelines may take place, in particular in primary fire fighting equipment.

Practical value. The obtained results create the prerequisites for the successful use in practice of polymer surfactants of the guanidine series as highly effective additives to water to increase the efficiency of fire fighting in natural ecosystems.
