Effects of Heat-Treatment in Hot Water and Steam Mediums on Gas Permeability of Beech Wood
2011 - IRG/WP 11-40557
Heat-treatment, as a major method of wood modification, improving dimensional stability, and natural durability, has been studied greatly from different aspects. The effect of heat-treatment on gas permeability, as an important physical property of wood, in two different mediums of hot water and steam, as well as in two buffers of 7 and 8, is the main topic of the present study. Hydrothermal treat...

Characterizing long term leaching behaviour of copper from preservative treated wood in a practical exposure scenario
2011 - IRG/WP 11-50278
To investigate the prediction of the long term emission of copper from preservative treated wood in a Use Class Class 3 scenario, treated boards were exposed vertically above ground to natural weather conditions. The study included two products; an amine copper ACQ-type formulation, air-dried after treatment to a 22 kg/m3 retention, and the same formulation which was hot oil vacuum dried after tre...

Glue-bond strength of simul (Bombax ceiba) plywood made of Neem (Azadiracta indica) leaves treated veneers
2013 - IRG/WP 13-40647
The glue-bond qualities of plywood made of treated simul (Bombax ceiba) veneers were investigated. The veneers were treated with cold and hot water solution of neem (Azadiracta indica, A. Juss.) leaves of different concentrations and treatment durations. The plywoods were made at three different pressures in hot press using urea formaldehyde glue. The glue-bond strength of untreated simul plywood ...

Development of Wood Modification – High melting point wax and hot oil treatments
2016 - IRG/WP 16-40768
This study covers an introduction to the projects where new facilities were created for developing wood modification. In this new research environment it is possible to treat wood with versatile equipment. First modifications with this equipment are going to be done in high temperature and pressure using high melting point waxes and hot oils.
Earlier studies, tests and commercial products show...
