Abstract

In this work, experimental studies of the fire-retardant efficiency of the DSA agent for oak wood have been carried out. The dependence of the fire retardant efficiency on the mass of the dry agent was obtained, applied, which is important when processing oak wood with DSA. The influence of the characteristics of wood of various species on the effectiveness of fire-retardant impregnating agents was investigated using the example of oak and DSA agents. It has been established that the standard method of studies of fire retardant efficiency using exclusively pine cannot provide fair data on the effectiveness of the agent in other types of wood. So, according to the instructions of the means that the subject, 3 applications are necessary, but for oak to achieve the 1st group of fire retardant efficiency, 7 applications were required. After the study of the fire-retardant efficiency of the DSA is provided in the norms for the example of oak wood processing, the fire-resistance of other types of wood can be analyzed. In the course of previous studies, the fire retardant characteristics of the main fire retardants for some types of wood have already been obtained. Species of wood with a high density have poor impregnation, as a result of which more treatments are required to achieve the 1st group of fire retardant efficiency. The resulting dependence of the weight loss of a treated wood sample on the amount of fire retardant composition during standard tests makes it possible to perform engineering, economic and other calculations when performing works on fire protection. Tested standard fire retardant per-formance testing method using pine exclusively. It has been determined that standard test methods cannot be objective when processing species other than pine. Particularly useful for research is the dependence of the weight loss of a treated wood sample on the amount of fire retardant composition during standard tests, the effect of the characteristics of wood of various species on the effectiveness of fire retardant impregnating agents on the example of oak and DSA agents. Oak has a higher specific gravity than pine, so it is more difficult to add a sufficient amount of active ingredient.
