Practical extraction of metals from CCA-treated wood
2014 - IRG/WP 14-50305
The extraction effects of acid concentration, reaction time and temperature in a microwave reactor on recovery of chromated copper arsenate (CCA)-treated wood were evaluated. Extraction of copper, chromium, and arsenic metals from CCA-treated southern pine wood samples with three different wood particle sizes (i.e., (1) 0.5 cm3, (2) 0.5x05x1.0 cm, and (3) 0.5x0.5x1.5 cm) was investigated using a m...

Outcomes deal to impregnability of Eucalyptus globolus L. wood after microwave treatment
2015 - IRG/WP 15-40712
Microwave treatment of wood has been used with several aims in many studies as drying, enhancement of pulp properties, angle fibre detecting, density evaluation, etc., and also to improve permeability of wood. Eucalyptus globulus Labill. is a refractory species which is spreading its use as solid wood for construction in Spain. Studies of different ways to improve their impregnability (uptake and ...

Permeability of Eucalyptus wood improved by microwave treatment
2017 - IRG/WP 17-40773
The wood species with low permeability may cause many problems during timber manufacturing. Extreme difficulties take place in fabricating new wood-based composites by impregnating low- permeability timber with functional materials, such as flame retardant, preservatives and resins. Microwave (MW) treatment can increase the permeability of wood both in transverse and longitudinal directions. The e...

The Effects of Pre-Microwave Treatment on Retention Levels And Some Mechanical Properties of Spruce Wood Treated with CCA
2017 - IRG/WP 17-40800
Microwave (MW) treatment of wood has been evaluated in recent years for different purposes by several scientists. Microwave conditioning improves permeability, reduces density and heat conductivity and changes dimensional stability. Furthermore, it could even improve the permeability of refractory wood species such as spruce and Douglas fir. In this study, MW pre-treatment was applied to spruce wo...

Efficacy of microwave treatments against Pine Wood Nematode
2019 - IRG/WP 19-20658
The pine wood nematode Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle (PWN) is the causal agent of “Pine wilt disease” affecting coniferous forests, and since its detection in 1999 in Portugal, has obliged the European Union to take action to prevent its spread (Decision 2006/133/CE). One of the main measures applied is the International Standard for Phytosanitary Measures ISPM No. 15 ...
