Distribution of fire retardant chemicals in kempas (Koompassia malaccensis)
1994 - IRG/WP 94-40037
Samples of Kempas (Koompassia malaccensis) heartwood were treated by vacuumpressure impregnation with solutions of monammonium phosphate, diammonium phosphate, ammonium sulphate or a borax-boric acid mixture. A commercial saltbased fire retardant formulation was also used. After slow air drying, the treated wood samples were sub-divided and zonal analysis carried out in order to determine the grad...

Effects of nano-silver on brittleness of heat-treated solid woods
2011 - IRG/WP 11-40572
The present study is aimed at the effect of heat-treatment of normal as well as nano-silver-impregnated Populus nigra, Populus deltoides, and Fagus orientalis on brittleness. Specimens were impregnated with 200 ppm water-based solution of nano-silver particles under 3 bars in a pressure vessel using empty-cell process. For heat treatment, both nano-silver-impregnated and normal specimens were kept...

Effect of Nano-Silane on Permeability in MDF as a Result of Susceptibility to Moulds and Fungi
2016 - IRG/WP 16-40716
Effects were studied of vapor chamber on specific gas permeability of nanosilane-treated medium-density fiberboards (MDF). Size range of nanoparticles was 20 – 80 nm. Nano-silane (NS) was used at four consumption levels of 0, 50, 100, and 150 g/kg dry wood fibers. Density of all treatments was kept constant at 0.67 g/cm3. Specimens were kept for 18 weeks in vaporized chamber; their specific gas ...
