DEPENDENCE OF BURNING OF MATERIALS FROM FIRE-PROTECTED WOOD, TAKING INTO ACCOUNT ITS HUMIDITY

Abstract

The article discusses the dependence of the effectiveness of different flame retardants, in this article three different compositions are presented, with the same drawing method to protect building structures from wood from the degree of humidity of the finished building material of wood beams. At the same time, wood modification continues to be one of the main areas of research for its durability and fire safety. Research is now focused on the multicomponent nature of systems, of which only some are of practical use. The main reason for this is the incompleteness of research. The results of studies on obtaining a stable response of the rate of change of temperature on the quality of flame retardant treatment taking into account moisture during fire exposure at a standard temperature curve on samples of wooden beams are given. Since humidity is one of the important characteristics when studying the behavior of wooden structures in case of fire, since it affects ignition and even less burning, while this humidity also affects the mass of the structure, which in turn affects the strength characteristics of wooden structures. The effect of flame retardants on the structure of the surface layer and the need to study the effect of various flame retardants on the performance properties of wood and on strength capabilities are also considered. A variety of factors is shown that affect the quality of flame retardant treatment for wood construction constructions. It is concluded that it is necessary to develop instrumental and methodological support that allows quick and accurate studies to determine fire-retardant efficiency and control the quality of fire protection work by surface coating of the protective layer on wooden building structures during operation and further study of the interaction of fire-retardant coatings during their repeated application Operated wooden structure.
