Hydrothermal modification for upgrading the durability properties of soft deciduous wood
2010 - IRG/WP 10-40494
To extend the application potentialities of soft deciduous wood, upgrading the durability properties, hydrothermal modification (HTM) of aspen alder and birch wood was investigated. The treatment was conducted in a multifunctional laboratory device WTT. In the previous cases it has been found that the treatment at 160oC improves the durability insufficiently. The modification at 180oC ensured a hi...

Exterior birch plywood: potentiality of the thermo-hydro treatment
2016 - IRG/WP 16-40743
It has been found in the present study that, in laboratory fungi tests after leaching with water (EN 84), exterior birch (Betula spp.) plywood, as birch solid wood, is subjected to degradation by rot fungi. This limits the use of such plywood outdoors or in building structures in high humidity conditions. The possibility to improve the birch plywood fungal resistance was investigated in two ways: ...
