| description | The problem of using fire-resistant materials for wooden building structures is to ensure their stability and durability when operating in atmospheric conditions, when it is possible to wash out flame retardants and lose fire resistance. The purpose of this study is to identify the indicators of fire hazard of wood, fire-proof coatings and the effect on them of the heat-insulating layer of coke formed, which allow justifying the effectiveness of the fire-resistant coating under the influence of temperature. The study used a comprehensive research method, which consisted in determining the fire-hazardous properties of fire-proof wood and methods for determining the operational properties of wood fire protection. It was found that upon applying a coating based on alkyd-polyurenitan varnish, due to the polymer film formed on the wood surface, the permeability of flame-retardant components decreases. Tests of fire-hazardous features of wood protection from fire have shown that the coating swells under the influence of heat flow and contributes to a significant heat-insulating layer of coke, which prevents oxygen from reaching the wood and, accordingly, hot temperature, which can ignite the wood. In general, the effectiveness of wood protection from fire shown that wood protected from fire belongs to hard-to-burn materials that slowly spread flames on a surface with low smoke-forming ability. The practical value of this paper lies in the fact that the obtained method for identifying the features of wood protection from fire, comprises determining both atmospheric and thermal properties, and allows establishing the operating conditions of fire protection and the use of products and building structures made of wood of a wide range of uses |
