祥云县大波那木质遗存物防腐加固工艺研究

Anticorrosion Reinforcement Process of Wooden Relics in Dabona Site of Xiangyun County

摘要: 以祥云县大波那遗址木质遗存物为研究对象，分析不同加固方法对遗址古木遗存物的加固效果，结果表明：福尔马林溶液仅能够杀灭表面细菌，无法达到长期保存效果；由于木材腐朽程度存在差异，PEG处理至完全包埋最少需要48~72 h，且相关处理方法繁琐；采用酚醛树脂可以简便易行地对古木进行原地、大批量加固处理，处理效果可以达到长期保存的要求。

Abstract: The effects of different reinforcement methods on wooden relics in Dabona Site of Xiangyun County were analyzed. The findings indicated that formalin solution can only kill bacteria on surface, and can not achieve long-term preservation. Due to the difference of wood decay degree, PEG complete processing is tedious and requires at least 48-72 h. Wooden relics can be easily treated in situ and in large quantities with phenolic resin, and reach the long-term preservation.
