FIRE PROTECTION OF WOOD BASED ON MULTICOMPONENT MIXTURES OF SUBSTANCES

Abstract

Analysis of scientific, technical, and patent literature highlights the relevance of further research aimed at developing new, more effective and economically attractive three-component mixtures of substances to be used as fire- extinguishing and fire-protective agents for wood. The composition (active basis) of the three-component systems was visualized using the Gibbs– Rosenbaum method. An equilateral triangle was constructed for this purpose, with its sides calibrated to represent component percentages in 20% increments. After obtaining the efficiency for each point, the data were entered into the matrix of the Statsoft Statistica software. This program was then used to construct an additive surface, the efficiency surface of the three-component mixture, a zone map, and a contour plot. Additionally, the equation describing the dependence of the mixture's efficiency on its composition was derived. To investigate the effectiveness of fire-extinguishing powders, a laboratory setup with a Bunsen burner was used. A mathematical calculation was performed to determine the predicted increase in the fire-extinguishing efficiency of powder E2 when preheated to a specific temperature t2, given its known fire- extinguishing efficiency E1at a lower ambient temperature t1.
