Abstract
Turkey oak (Quercus cerris L.) wood has some technological limitations that reduce its market value despite its great potential. This study evaluated the effect of indirect steaming on the resistance to footprints of Turkey oak wood in order to assess its use as parquet. Steaming treatments were carried out on green wood at 120°C and for 24 hours, while a drying process was carried out on all boards at 63°C, 120 mm Hg of vacuum for 34 days. Good elastic restoration was observed for untreated wood, while for treated wood the resistance to footprints was higher in the radial than in the tangential direction. By contrast, a significant negative effect on the elastic recovery of the original dimensions was found which was higher in radial than in tangential direction, when a load was conducted on steamed wood.
Zusammenfassung
Das Holz der Zerreiche (Quercus cerris L.) unterliegt einigen technologischen Nachteilen, die seinen Marktwert trotz seines großen Potenzials verringern. Diese Studie untersucht den Einfluss einer indirekten Dampfbehandlung auf den Eindruckwiderstand dieses Holzes im Hinblick auf seine Verwendung als Parkett. Dampfbehandlungen wurden am frischen Holz bei 120°C und über eine Dauer von 24 Stunden durchgeführt. Das daraus hergestellte Schnittholz wurde im Vakuum bei 63°C und 120 mm Hg über einen Zeitraum von 34 Tagen getrocknet. Unbehandeltes Holz wies eine gute elastische Rückfederung auf. Behandeltes Holz wies in radialer Richtung einen höheren Eindruckwiderstand auf als in tangentialer Richtung. Im Gegensatz dazu ergab sich bei gedämpftem Holz in radialer Richtung eine signifikant geringere Rückfederung als in tangentialer Richtung.
