Changes in physical and water sorption characteristics of three solid woods after one-sided surface charring

Cupressus lusitanica, Gmelina arborea and Tectona grandis wood samples from fast-growth plantation were charred with a hot plate using three temperatures (300 °C, 350 °C and 400 °C ± 3°C) for 10 minutes. Wood density, surface quality (color and presence of splits) and sorption characteristics (wetting rate and water uptake) were evaluated.取自速生人工林的葡萄牙柏木（Cupressus lusitanica）、云南石梓（Gmelina arborea）及柚木（Tectona grandis）木材试样，通过热板法在300℃、350℃与400℃±3℃三个温度条件下进行10分钟的炭化处理。随后对其木材密度、表面质量（颜色与开裂状况）以及吸附特性（润湿速率与吸水率）开展了测试与评价。
