Application of the Guggenheim, Anderson, de Boer (GAB) equation to sealing treatments on pine wood

摘要

Surface treatments can modify the materials behavior toward water sorption phenomena and the GAB equation is here proposed to study pine wood samples treated with difference sealing materials limiting in different ways the access and release of water moisture. Particularly, the modification of the k_(GAB), C_(GAB), V_(ads) and S_(GAB) parameters as a function of the applied coating is studied here in order to explore the usefulness of such variables as indicator of the presence of chemical treatments on wood at high RH values.
