Abstract
The effect of wood material type on biocide retention and distribution during supercritical fluid impregnation was assessed using three different wood types including solid wood, plywood and oriented strand board (OSB). The result revealed that biocide treatability differed with structural composition and permeability of the various materials. Low treatability of plywood might be attributed to interferences of glue line limiting fluid movement. OSB samples showed higher biocide retentions, resulting from the presence of interconnecting gaps permitting more open flow.
