Abstract

ABSTRACT An innovative eco-friendly technology, applied to improve the quality of the short rotation teak, was wood modification by heat treatment. The study was to investigate the effects of heat treatment at 180°C, 200°C, and 220°C on the characteristics of the short rotation teak. The results show that the short rotation teak degraded hemicellulose and increased α-cellulose and lignin after the heat treatment. Anti-swelling efficiency value after heat treatment was improved ranging between 12.9% and 46.7%, indicating an improvement in dimensional stability. The MOE and MOR values decreased after heat treatment. The heat treated sample at 180°C after graveyard test was the lowest in weight loss, which presented good durability against termite (rating 9) and decay (rating 10). The surface roughness and SFE values decreased as the heating temperature increased. The heat treated at 220°C provided the lowest K-values (0.04 for acrylic and 5.04 for alkyd paint) which indicate the poorest wettability.

热处理对短旋柚木特性的影响

摘要采用热处理对木材进行改性，是一项创新的环保技术，旨在提高短轮柚木的质量。本研究旨在研究180°C、200°C和220°C的热处理对短旋柚木特性的影响。结果表明，短轮柚木经热处理后，半纤维素降解，α-纤维素和木质素增加。热处理后的防溶胀效率值提高了12.9%至46.7%，表明尺寸稳定性有所提高。热处理后MOE和MOR值降低。墓地试验后180°C的热处理样品的重量损失最低，对白蚁（等级9）和腐烂（等级10）具有良好的耐久性。表面粗糙度和SFE值随着加热温度的升高而降低。在220°C下热处理的K值最低（丙烯酸漆为0.04，醇酸漆为5.04），这表明润湿性最差。
