东南沿海地区木构文物建筑白华与斑痕变色病害的表征机制研究

Characteristics of Salt Efflorescence and Discolor on Wooden Relic Buildings in the Southeast China

自然因素是造成文物建筑长时间持续破损的主要因素,东南沿海地区的木构文物建筑长期浸润于潮湿环境中,极易发生病变从而影响建筑寿命。文章将表层病害白华与斑痕变色作为研究对象,通过大量案例调查,记录和评价木构文物建筑的破损状态,进而分析白华与斑痕变色病害的表征法则,探寻表层病害发生的致病机制,从而为木构文物建筑保护提供基础资料。

Nature is the main factor which causes the continuous damage of cultural relics.The wooden relic buildings in the southeast coastal area have been infiltrated in the humid environment for a long time,which is very easy to cause damages and reduce the life.In this paper,the surface diseases,salt efflorescence and discolor as the research objects,by case investigation,are recorded and evaluated the damaged state of wood structure cultural relics.And then it can analyze the performance rules of the diseases,explore the pathogenesis of surface diseases,so as to provide basic information for the protection of wood cultural relics.
