Investigation on the effect of acetylation and the resin type on the biological resistance of aspen tree layered particleboard

This research was conducted to evaluate the effects of acetylation and the resin type on three layered populus particleboard against white-rot fungus, Trametes versicolor. Populus particles were acetylated at three levels of acetyl content (WPG of 0, 8.39% and 17.27%). In manufacturing of single and...

Description
Summary:	This research was conducted to evaluate the effects of acetylation and the resin type on three layered populus particleboard against white-rot fungus, Trametes versicolor. Populus particles were acetylated at three levels of acetyl content (WPG of 0, 8.39% and 17.27%). In manufacturing of single and three layered boards with acetylated particles two type of resin, urea formaldehyde and isocyanate( as adhesives) were employed. The results indicated positive role of acetylation in reducing decay rate. Weight loss of boards made from isocyanate was less than the boards containing urea formaldehyde resin. Also, three layered boards showed higher resistance against the fungus compared with single layered boards.
