饱水木质文物由于在地下长期的埋藏环境中,因为化学和生物的作用,其成分和结构都发生了不同程度的变化。出土后,由于失去水分,会发生严重的变形,破坏了文物的原始形态。本文拟从木材的结构与成分出发,对木质文物的腐蚀类型进行了划分,尝试分别从化学腐蚀与物理形变的角度,具体分析各种腐蚀病害的成因和机理。
Due to the long-term buried underground environment, the water-saturated woody relics vary in composition and structure due to the effects of chemistry and biology. After unearthed, due to loss of water, serious deformation will occur, undermining the original form of cultural relics. This paper, starting from the structure and composition of wood, classifies the types of wood artifacts, trying to analyze the causes and mechanisms of various kinds of corrosion diseases from the perspective of chemical and physical deformation respectively.
