Sawn wood drying regimes following initial microscopic changes in the structure of wood resulting from hydro-thermal treatment

Market-oriented research supported by the Ministry of Education and Science of the Republic of Latvia

The study gives completely new technologies and lumber drying regimes that use initial hydrothermal treatment of materials to be dried, achieving permanent changes in the colloidal structure of biological capillaries. The biological structure of freshly cut wood is fully capable of reacting to various fluctuations in temperature and air relative humidity and, depending on them, creating appropriate changes in the capillary-porous colloidal structure. The aim of the study is to ensure that these changes are irreversible, that the physico-mechanical properties of wood do not decrease, and that the drying process proceeds faster.
