Influence of the substitution of phenol with lignin cleavage products in phenol-formaldehyde impregnation resins for wood modification on the fungal decay resistance and impregnation depth
2024 - IRG/WP 24-30805
The impregnation modification of wood with phenol-formaldehyde (PF) resins increases the woods dimensional stability and resistance against fungal decay. However, to decrease the usage of non-renewable resources, the substitution of phenol has been a topic of scientific interest. Lignin is a currently underutilized resource with a chemical structure that contains phenolic units. For adhesive appli...

Assessment of hydrophobic properties of acetylated and furfurylated Korean wood species
2024 - IRG/WP 24-30812
To increase the utilization of Korean wood species, the hydrophobic properties of the most commonly used wood species in Korea were compared according to wood modification. Pinus densiflora (sapwood and heartwood) and Larix kaempferi (heartwood) were selected as test wood species, and Pinus radiata (sapwood) was selected as the control wood species. The wood modification was performed by acetylati...
