饱水清代木材的构造腐朽程度及加固处理对其颜色的影响

以“小白礁I号”沉船主要用材为研究对象，系统研究了饱水考古木材构造特征、腐朽程度与加固剂种类对其加固处理颜色的影响。结果表明：加固剂可提高考古木材尺寸稳定性；坡垒（散孔材）比柚木（环孔材）的加固处理色差变化大；加固剂增重率和考古木材腐朽程度会影响其色差变化；加固剂分子量及其分子结构间差异是造成考古木材加固处理后各色度学参数变化规律不同的主要原因。

The Influences of the Anatomical Structure and Deterioration State of Wood from a Qing Dynasty Shipwreck on Wood Color After the Consolidation Treatment

The waterlogged archaeological wood from the 'Xiaobaijiao I' shipwreck were used as the representative to investigate the influences of the wood anatomical structure, the deterioration state and consolidants type on wood color after the consolidation treatment. Results showed that consolidants improved the dimensional stability of waterlogged wood. The waterlogged Hopea wood displayed the larger change of color than those of waterlogged Tectona wood. Besides, the wood color after the consolidation treatment became dark progressively as the increase in the weight percentage gain of the consolidants or the worse preservation state of archaeological wood. The variations in colorimetric parameters of archaeological wood samples after the consolidation treatment, were mainly resulted from the different molecular weights and molecular structures. This study will provide a theoretical basis for the conservation of waterlogged archaeological wooden artifacts in China.
