Abstract

The adhesive properties of two domestic hardwood species-beechwood and oakwood have been estimated by analyzing the surface chemical composition determined by ESCA (XPS). The estimated reactivity of wood, based on the occurrence of certain types of carbon bonds that corresponds to specific wood components, was proved by wetting measurements and the determination of adhesion expressed as the pull-off strength of polyurethane coating. Beechwood showed better adhesive properties than oakwood,

Vergleich der Oberflächeneigenschaften der Buche und der Eiche mit Hilfe der ESCA Methode

Zusammenfassung

Die adhäsiven Eigenschaften zweier heimischer Bäumarten -der Buche und der Eiche - wurden durch Analyse der chemischen Oberflächenzusammensetzung, die durch ESCA (XPS) bestimmt wurde, eingeschätzt. Ebenso wurde die Holzaktivität bewertet, die sich auf die Anwesenheit unterschiedlicher Arten von Kohlenstoffbindungen in den einzelnen Holzkomponenten gründet. Dazu wurden Befeuchtungsmessungen herangezogen sowie das Bestimmen der Adhäsion, ausgedrückt als Abreißfestigkeit der Polyurethanbeschichtung. Die Buche zeigte bessere adhäsive Eigenschaften als die Eiche.
