Abstract

The energy state of the surface plays a decisive role in the fundamental physical processes of adsorption,
the migration of adsorbed particles along the surface, and the chemical interaction of particles near the separation of
two phases. The quality of fire-retardant surface treatment of the material is largely determined by the level of adhesive contact at the interface "coating – material", which in turn depends on the nature of the interphase interaction.
The free energy of the wood surface can be reduced as a result of adsorption of plasticizers and stabilizers, parts of which have a force field of lower intensity than parts of the material. Thus, plasticizing and stabilizing substances that reduce surface tension can be adsorbed on the surface of the material, and therefore the amount of adsorption is determined by the free surface size, concentration, temperature and nature of the adsorbent and adsorbent, and the higher the concentration of the substance, the greater the adsorption. The paper presents the results of studies of free surface energy and its components (polar and dispersed) for reeds. The sequences of polarity change and their ratio to the main component of plant material after surface treatment with a fire-retardant coating, which are consistent with the structural and functional features of reeds.
