Název v původním jazyce

Densification of beech wood and fixation of compressive deformation by steaming at lower temperatures

Popis výsledku v původním jazyce

The process of wood plasticization and densification that improves mechanical properties has been known for decades, but the utilization in wet conditions is limited due to the problems with dimensional stability. The deformation produced during the process is not stable and recovers almost totally when re-moistened and heated. This phenomenon is known as compression set recovery (KUTNAR, KAMKE 2012) or shape memory (NAVI, SANDBERG 2012). Treatment in high temperatures can decrease the compression set recovery, but mechanical properties are negatively affected (HILL 2006). Process with saturated steam is more efficient (KUTNAR, KAMKE 2012), so that complete fixation can be reached for example in 20 min at 180oC or 4 min at 200oC (NAVI, SANDBERG 2012). The process with lower temperatures takes more time; however, the mechanical properties are less decreased (HEGER 2004).
