Heat treatment of wood strands for OSB production: Effect on the mechanical properties, water absorption and dimensional stability
2002 - IRG/WP 02-40238
The effect of heat treatment on the mechanical and physical properties of commercial OSB strands was evaluated. Heat treatment was applied under inert atmospheric conditions to wood strands. The aim of this study was to examine the heat treatment parameters to achieve significant reduction of thickness swelling (upon exposure to moisture in service) without causing excessive
reductions in stren...

The effect of high temperature and long pressing time on the dimensional stability and decay resistance of OSB
2002 - IRG/WP 02-40237
The exterior use of OSB is restricted because when it is exposed to wet conditions swelling, loss of internal bond strength (IB) and decay occur. In this study an alternative process of pressing which results in the production of dimensionally stable and a more decay resistant strandboard was investigated. Boards were pressed at elevated temperatures for prolonged pressing cycles and their physi...

Soil-bed decay resistance evaluation of strandboards treated with preservative at different points of the manufacture process after 18 months exposure
2002 - IRG/WP 02-40230
Strandboards were treated with a copper-boron water-based preservative at different points of manufacture process namely, green strand diffusion, vacuum, spray application in the resin blender and post manufacture heat and cold quench.
Preservative was applied to achieve five different retentions (0, 1.5, 3, 6, 12 kg m-3). The modulus of rupture and modulus of elasticity were assessed before expo...

Effect of point of preservative addition on the mechanical and physical properties of strandboard treated with Tanalith 3485
2000 - IRG/WP 00-40152
Preservative has been added to a PF bonded strandboard at various different stages in the manufacturing cycle and the physical and mechanical properties of the boards have been evaluated (modulus of elasticity, modulus of rupture, thickness swelling, water absorption, internal bond strength, and shear strength). Preservative addition has been examined at five different stages namely green strand d...

Observation on the performance of CCB and creosote treated fence posts after 18 years of exposure in Greece
2002 - IRG/WP 02-30288
The effect of 18 years exposure on toughness of CCB and creosote combination treated pine was examined. Vacuum CCB treated fence posts were subsequently treated at their lowest part (ground contact) with creosote using the open hot and cold tank process. After 18 years exposure under warm dry temperate climatic conditions in Greece, samples were taken from the above ground contact, top, middle a...
