Abstract

Cultural property made of wood may require consolidation with soluble resins because, of biological deterioration. Certain effects of solvents and moisture on consolidated wood were studied, using Douglas-fir wood damaged by bacteria. It was found that the mechanical properties of consolidated wood are quite stable over a period of 3.5 years, but that retained solvents may have an effect with some treatments. Consolidants do not appear to affect wood hygroscopicity because of their high molecular weight. Wood will swell during consolidation treatment, the amount being proportional to the swelling potential of the solvent used.

Zusammenfassung

Kulturgut aus Holz kann wegen biologischen Verfalls eine Verfestigung mit löslichen Kunstharzen benöfigen. Gewisse Einflüsse von Lösungsmitteln und Feuchtigkeit auf verfestigtes Holz wurden an von Bakterien geschädigtem Douglasienholz untersucht. Es wurde festgestellt daß die mechanischen Eigenschaften von verfestigtem Holz über eine Zeitspanne von 3,5 Jahren recht stabil sind, daß aber zurückgehaltene Lösungsmittel bei manchen Behandlungen einen Einfluß haben können. Die Verfestigungsmittel scheinen wegen ihres hohen Molekulargewichts keinen Einfluß auf die Hygroskopizität auszuüben. Das Holz quillt während der Verfestigungsbehandlung, und zwar im Verhältnis zu dem Quellungsvermögen des verwendeten Lösungsmittels.
