Identifying parameters for wood protection against water absorption
Keywords:thermally modified wood, resistance to water, ange in the structure of wood, treatment with a hydrophobic agent
An issue related to using wood and timber for building structures is to ensure the stability and durability during operation within wide limits. Therefore, the object of research was the inhibition of the process of water absorption of pine and hornbeam wood during a thermal change in its structure. It is proved that in the process of thermal modification of wood, its structure changes, and, accordingly, water absorption. Namely, the maximum increase in mass under the action of water on an untreated sample of wood was more than 40 %, after thermal modification – less than 35 %. The increase in the mass of wood samples thermally modified and treated with a hydrophobic agent was less than 25 %. On the basis of the obtained results of physicochemical studies, discrepancies were found in the IR spectra of wood, both during thermal modification and with additional treatment with a hydrophobic agent, indicating structural changes in the components. In particular, the decrease or absence of the intensities of the absorption bands of some functional groups and the appearance or intensification of others. On the original hornbeam and pine thermogram, thermally modified, and thermally modified with the addition of a hydrophobic coating, thermogravimetric curves are similar to each other and are characterized by a loss of sample mass. This is possible with increasing temperature due to the processes of dehydration, destruction of hemicellulose, lignin, and cellulose with the formation of a non-combustible residue. During heat treatment of cellulose in the region of temperatures of 150÷450 °C, two processes take place in parallel. This is dehydration, accompanied by the destruction of the pyranose cycle and carbonization to form a carbon residue. Also, the process of destruction of glycosidic bonds while maintaining hydroxyl groups, accompanied by regrouping of pyranose cycles.
