JOURNAL FREE ACCESSChromated-copper-arsenate (CCA) treated Douglas-fir was laminated using a commercial phenol-resorcinol resin. CCA treatment enhenced the water repellency of wood especially in the presence of extractives. The shear strength of CCA treated wood was significantly lower in wet condition after six cycles of vacuum-pressure test than that of untreated wood. Slight removal of treated wood surface by planer contributed to better bonding, although it was not enough.
The characteristics of treated wood surface was analyzed by x-ray photoelectron spectroscopy (XPS). CCA treatment increased C1 (carbon bonded to carbon and/or hydrogen) and decreased C2 (carbon bonded to one oxygen) in XPS Cls spectra, indicating migrated extractives enhanced the water repellency of treated surface. The removal of hydrophobic surface of CCA-treated wood decreased C1 and increased C2 on the new surface.View full abstractDownload PDF (353K) -
