Modification of Wood with Monoethanolamino-borate by The Data of X-Ray Photoelectron Spectroscopy

The difficulty of wood protection from biocorrosion and fire is due to the fact that modifiers in use are washed out from the surface of the substrate under the influence of environmental factors. This results in a rapid loss of the protective effect and other practically important wood characterist...
