Laser incising of spruce lumber for improved preservative penetration
1991 - IRG/WP 3646
Red spruce heartwood specimens were incised using a range of laser beam power levels and pulse durations. The penetration of CCA through these holes into the wood was monitored after pressure treatment. In addition, green and dried spruce samples were incised using two patterns with incision densities of either 16.1 holes/in² or 21.3 holes/in². Following CCA pressure treatment the samples were t...

Preliminary investigation of the durability and performance of 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) treated aspen strandboard
2024 - IRG/WP 24-30804
Wood modification technologies are growing in popularity because of their potential to improve wood properties by permanent covalent chemical modifications rather than chemical impregnation. These features can be utilized in wood composites to help improve dimensional stability and composite resistance to fungal decay. In this study, 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) was used to m...
