Effect of Particle Size on Wax Distribution in Paraffin Wax Emulsion Impregnated Wood
2017 - IRG/WP 17-40779
Paraffin wax emulsion impregnation has been a common eco-friendly approach for improving water repellency of wood. In this study, southern pine (Pinus spp.) and Scots pine (Pinus sylvesteris L.) samples were impregnated with paraffin wax emulsions of different solid contents and particle sizes, and then the time domain nuclear magnetic resonance (TD-NMR) was used to elucidate the influence of part...

Long-term field exposure of wood-plastic composites processed on a commercial-size extruder
2020 - IRG/WP 20-40894
Wood-plastic composites (WPC) contain wood fiber (or flour), thermoplastics and additives and are exposed to UV light, moisture, and biological deterioration in outdoor installations. Accelerated laboratory tests can help to predict the durability of WPCs, but long term evaluations are needed to validate these results. Field exposed above-ground WPC deck boards (30.5 x 139.7 x 609.6 mm) and in-gro...
