Abstract | Plywood panels collected from thirty seven mills located throughout the Pacific Northwest they were treated with chromated copper arsenate Type C (CCA-C) or ammoniacal copper zinc arsenate (ACZA) using modified full cell and full cell processes respectively. Preliminary tests were performed to determine plywood sample size, replication, and treating schedule. ACZA produced better preservative treatment than CCA in plywood from all regions. For both treatments, outer veneers had higher preservative penetration than inner veneers. Plywood panels from Washington, Oregon, or Idaho were similar in treatability and were better treated than plywood from Montana. Differences in plywood treatability between Washington, Oregon, Idaho and Montana differed from those previously found in lumber. Species composition and veneer distribution also influenced plywood treatability. Within a geographic region log source was linked to plywood treatability in panels containing only one species. |
