Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] lumber was
converted to flakes, which were dip treated with three concentrations
each of copper chrome arsenate Type C (CCA-C), and disodium octaborate
tetrahydrate (TIM-BOR). Azaconazole [1-[{2-(2,4-dichloropheny1)-1,3-
dioxolan-2-yl}methyl]-1H-1,2,4-triazole] was used as powder. The
flakeboard panels (305 x 304 x 13 mm) were made using phenolformaldehyde...
The effect of pretreatment of Douglas-fir flakes with CCA-C, borate, and azaconazole on properties of flakeboard was studied. Flakes had higher retention levels of CCA-C and borate in their ends than in their centers. The distribution of chemicals was uniform in panels, which indicates that the chemicals did not migrate...
