Abstract

In this study the effect of an atmospheric pressure plasma treatment by a dielectric barrier discharge (DBD) on the wettability and absorption characteristics of thermally modified beech veneer is investigated. A common immersion test using water and melamine solution has been conducted and showed improved wettability and liquid uptake after plasma treatment. Determination of the weight percent gain (WPG) confirmed increased melamine content after plasma treatment.

Verbesserte Absorptionscharakteristiken von thermisch behandeltem Buchenholzfurnier nach einer Plasmabehandlung

Zusammenfassung

In dieser Arbeit wird der Effekt eines Plasmas unter Atmosphärendruck nach dem Prinzip der dielektrisch behinderten Entladung auf die Benetzungs- und Absorptionscharakteristik von thermisch behandelten Buchenholzfurnieren untersucht. Ein einfacher Immersionstest unter Verwendung von Wasser und Melaminlösung wurde ausgeführt und zeigte eine verbesserte Benetzung und Flüssigkeitsaufnahme nach einer Plasmabehandlung. Die Bestimmung des WPG (weight percent gain) bestätigte einen erhöhten Melamingehalt nach einer Plasmabehandlung.
