Improvement of the Durability of Heat-treated Wood against Termites
Thermal modification is an attractive alternative to improve the decay durability and dimensional stability of wood. However, thermally modified wood is generally not resistant to termite attacks, limiting the field of application of such materials. One way to overcome this drawback is to combine thermal modification treatment with an additional treatment. One such treatment is the impregnation...
متن کاملPerformance Characterization of Coatings on Treated-wood
Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...
متن کاملEvaluation of Decay Resistance for Steam-heat- Treated Wood
The objective of this research was to evaluate the influence of steamheat treatment on the decay resistance of Chinese white poplar and Chinese fir wood against the wood-rotting fungi Gloeophyllum trabeum (Pers.:Fr.) Murrill. The Chinese white poplar and Chinese fir specimens were obtained from Shandong and Hunan provinces, respectively. They were steam-heat-treated at 170, 185, 200, 215, or 23...
متن کاملWeatherability and Leach Resistance of Wood Impregnated with Nano-Zinc Oxide
Southern pine specimens vacuum-treated with nano-zinc oxide (nano-ZnO) dispersions were evaluated for leach resistance and UV protection. Virtually, no leaching occurred in any of the nano-ZnO-treated specimens in a laboratory leach test, even at the highest retention of 13 kg/m(3). However, specimens treated with high concentrations of nano-ZnO showed 58-65% chemical depletion after 12 months ...
متن کاملPhysiological Effects of Touching Coated Wood
This study examined the physiological effects of touching wood with various coating with the palm of the hand on brain activity and autonomic nervous activity. Participants were 18 female university students (mean age, 21.7 ± 1.6 years). As an indicator of brain activity, oxyhemoglobin concentrations were measured in the left and right prefrontal cortices using near-infrared time-resolved spect...
