Tratamiento térmico y químico como mejora del proceso de densificación de tres maderas de plantaciones forestales

The densification of wood through the use of compressive forces combined with temperature and steam is called thermo-hydro-mechanical densification. However, densified wood is sensitive to moisture and the release of internal forces and tends to recover its initial dimensions. This phenomenon is called set-recovery and can be reduced by thermal and chemical modification of the wood. In Costa Rica, the densification process is relatively new and is being applied to fast-growing timber species with densities of less than 0.45 g/cm³. Currently, work has been done on the densification of Alnus acuminata, Vochysia ferruginea, and Vochysia guatemalensis wood; however, although it was possible to increase its density by up to 80%, the wood tends to recover its initial dimensions when subjected to changes in humidity. Therefore, this project aims to perform a thermal modification after the densification process and a chemical modification with acetylation and furfuration prior to densification. Then densified wood will be evaluated in its

dimensional stability, water absorption, the percentage and changes in the porosity of the wood, hardness and changes in its anatomy

evaluar el efecto de la modificación térmica y química como tratamiento complementario del proceso de densificado de la madera de tres especies de plantaciones forestales (Alnus acuminata, Vochysia guatemalensis y Vochysia ferruginea) en Costa Rica.
