Abstract
The penetration profiles of CCA preservatives and of Cu, Cr, and As in sawn timber in the radial and tangential directions are described. Interesting differences in the penetration in these two directions can be observed. Variations of the penetration profiles are also noticed according to the impregnation process used. Similar profiles for industrially-treated pine and eucalyptus poles show marked differences in behaviour between pine and eucalyptus. The unusual trends shown by eucalyptus are quantified and their cause explained in term of the physico-chemical characteristics of the system.
Zusammenfassung
Es werden die Penetrationsprofile von CCA-Holzschutzmitteln und von Cu, Cr und As im Schnittholz in Radial- und Tangentialrichtung beschrieben. Es werden interessante Unterschiede der Penetration in den beiden Richtungen beobachtet, und Abweichungen der Penetrationsprofile entsprechend dem angewandten Imprägnierungsverfahren festgestellt. Ähnliche Profile industriell behandelter Kiefern- und Eukalyptusmasten zeigen deutliche Unterschiede im Verhalten von Kiefer und Eukalyptus. Die ungewöhnlichen Tendenzen, die Eukalyptus zeigt, wurden in der Form der physikalisch-chemischen Charakteristik des Systems quantitativ bestimmt und deren Ursache erklärt.
