The method of mathematical planning of the experiments was used for determination of the leading factors influencing on the efficiency of nitrogen-phosphorus-containing flame inhibitors for wood, peat. It was found, that the inhibition of free radical reactions in the gaseous phase with volatile nitrogen products is dominating mechanism of burn ter...

In the chosen direction g, a consistent displacement was performed at step α 1 = 0.2 and then at step α 2 = 0.4 with transition to the ¦rst point with coordinates: X For each of the two new FRC pertaining to the coordinates in the nat- ural variables, ¦ve experiments were conducted to determine the e©ciency of §ame-retarding and ¦re-extinguishing of peat and wood and which furnished the experimental results, as well as average values of vectors y peat and y wood listed in Table 2. Thus, the new recipe made it possible to improve extinguishing and ¦re-resisting properties of FRC for both peat and wood. ...

Thus, the new recipe made it possible to improve extinguishing and ¦re-resisting properties of FRC for both peat and wood. Inasmuch as fur- ther displacements in the selected direction g at α 3 = 0.6 has led to an FRC, ¦re tests of which showed lower ¦re-extinguishing and ¦re-protection e©ciencies (see Table 2), the previous FRC with parameters x (2) 1 = 6.17, x (2) 2 = 2.87, and x (2) 3 = 6.21 was adopted as the best formulation. Application of the mathemat- ical method of experiment planning allowed to optimize the FRC and increase its ¦re-retardant and ¦re-extinguishing e©ciency with respect to both peat and wood as compared to the initial recipe. ...
