The studies of influence of wood fire protection on ignition have established parameters of flame propagation and combustion suppression which makes it possible to influence this process. It was proved that fire protection consists in creation of a layer on the material surface which prevents the material from warming up to its critical temperature. Experimental studies confirmed that the untreated wood specimen ignited under thermal action resulting in its combustion with a burnout rate of 18 g/(m2∙s). With an increase in intensity of combustion of the ignition gas mixture by 25 % and 50 %, rate of the specimen weight loss increased by 1.4 times and 1.8 times, respectively. In the case of wood impregnation, the rate of weight loss was reduced to 4.8 g/(m2∙s) due to decomposition of flame retardants under thermal action with release of non-combustible gases which inhibited material oxidation and formed a coke layer. When treating wood with an inorganic coating, a heat-resistant ceramic film is formed on the wood surface which reduces the burnout rate 3.8 times. But with an increase in intensity of combustion of the igniting gas mixture by 50 %, the wood specimen has ignited which was reflected by increase in the weight loss rate. Application of organic-mineral coatings under thermal action has resulted in formation of a layer of foamed coke, inhibition of heat transfer from high-temperature flame and reduction of burnout rate to 3 g/(m2∙s). This has made it possible to determine conditions of change and inhibition of the combustion parameters for fire protection of wood by creation of a barrier for thermal conductivity. The results of comparison of experimental data on the wood burning rate with the derived analytical equations have shown conformity between them. Thus, there are grounds to assert about the possibility of directed regulation of processes of wood fire protection by using flame retardant coatings capable of forming a protective layer on the material surface that reduces the wood burnout rateReferences
