“…As a result of studies to determine the dependence of the color range of thermally treated wood on the temperature and duration of treatment, the color range of oak thermowood 25 mm thick was obtained ( Table 2). During the experiment, it was revealed that to accelerate the process of heating, and, accordingly, darkening of the material, it is necessary to use high temperature [9], the choice of the range of which should be determined taking into account the physicomechanical properties of wood changing under the influence of high temperatures. It is important to take into account that the improvement of some characteristics may lead to the deterioration of others.…”

“…A characteristic that unites these methods of heat treatment of wood is the treatment temperature in the range of 180 to 240 ° C, which is explained by the physicochemical changes that occur in the wood at a given temperature range. In all methods, the duration of the stage of sample processing in a high-temperature environment was determined by the completion of the thermal modification process, which is characterized by a change in sample mass between two measurements of less than 1% [9]. Samples were measured every 30 min.…”

This paper proposes the use of an array of heat-treated wood of various species to make parametric furniture for the purpose of operation in the exterior, and on objects in conditions of high humidity. The dependence of change in the color range of thermowoods depending on the temperature and duration of treatment is presented. Experiments were carried out to study the biological stability of thermally modified wood treated by various technologies including: vacuum-convective thermal modification in superheated steam, convective thermal modification in high-pressure saturated steam, as well as in hydrophobic liquids, in flue gas and vacuum-conductive thermal-modifying. The degree of resistance of wood was determined, which allows to conclude that the mass losses of heat-treated specimens caused by the destructive action of fungi are significantly lower compared to untreated ones. The researchwas conducted to determine the numerical characteristics of microroughness of the polished surface of wood, thermally modified at different temperatures.

The greening of processing waste from logging and woodworking industries involves measures to prevent the negative impact of production processes on the natural environment and is enabled by the development of resource-saving techniques that minimize harmful emissions to the environment. These production operations are based on hydrolytic cleavage of glycoside bonds of vegetable biomass polysaccharides with the formation of monosaccharides as the main reaction products. Despite the wide range of available methods of processing wood into promising materials (heat treatment, pyrolysis, hydrolysis, etc.), one of the most effective methods is to produce sugars by weak acids hydrolysis. In this regard, the paper describes the technology of high-temperature hydrolysis of pine sawdust with sulfurous acid in order to detect reducing substances (RS) in the hydrolysis residue. The paper considers the effect of sulfurous acid, temperature, and treatment time on the yield of RS.
