Abstract
ZnO is a cost-effective and more environmentally friendly wood preservative than other metallic-based formulations. ZnO-stearate treatment imparts superhydrophobicity to wood surfaces, thereby providing triple protection to wood products, i.e., superhydrophobicity, inhibition to insects and microorganisms, and UV radiation protection. The objective of this study was to evaluate ZnO-stearate hydrophobic treatments of southern pine sapwood for resistance to Formosan subterranean termites. The data indicated that ZnO-stearate superhydrophobic treatment of southern pine wood samples received excellent mean visual ratings and mean weight loss values. The mean termite mortality was moderate. Unidentified fibril-like substances were found on the wood surfaces that were damaged by the termites.
Zusammenfassung
ZnO ist ein kostengünstiges und umweltfreundlicheres Holzschutzmittel als viele andere Rezepturen auf Metallbasis. Eine Imprägnierung mit ZnO-Stearat verleiht der Holzoberfläche Superhydrophobizität mit Dreifachschutz, d.h. Superhydrophobizität, Wirkung gegen Insekten und Mikroorganismen sowie Schutz vor UV-Strahlung. Ziel dieser Studie war es, die Resistenz von mit ZnO-Stearat behandeltem Southern Pine Splintholz gegen die Formosan Bodentermiten zu untersuchen. Die Ergebnisse zeigten, dass der mittlere visuell festgestellte Zerstörungsgrad und der mittlere Masseverlust der mit ZnO-Stearat superhydrophobisch behandelten Southern Pine Splintholzproben sehr gering waren. Die mittlere Termitensterblichkeitsrate war mäßig. Auf den durch Termiten befallenen Holzoberflächen wurden unbekannte fibrillenartige Substanzen gefunden.
