Влияние поверхностной обработки древесины на огнестойкость деревянных конструкций

Flame spread during combustion of materials determines the intensity and dynamics of fire, depending on the effectiveness of the protection and the burn-up rate of building structures in the flame burning. A mathematical model of burn-up rate of wood. For obtaining analytical equation calculated burning rate of refractory material with the corresponding value of the indicator of slowing down. installations, the change of particular structure and properties of the contact zone of the wood, a layer of wood is characterized by resistance to external sources of energy (high flame), which suggests the protective nature of the wood surface modifiers. Stability of modified wood estimated to change the compressive strength of the average 3 times higher compared with the untreated wood structure burnup. Thus, treatment of wood helps to reduce the burn-up rate and thus increases the resistance of structures.
