摘要
【目的】研究石质文物在复杂气候条件下的加速劣化问题,为制定科学保护策略提供依据。【方法】以灰砂岩、红砂岩、石灰岩、大理石和花岗岩为研究对象,模拟浙江省亚热带季风气候条件,设计涵盖冻融循环、盐结晶浸泡及酸蚀处理的实验室加速老化试验;结合质量试验、硬度试验及扫描电镜微观分析,系统评估五类石材的劣化规律。【结果】红砂岩因氧化铁胶结物和高孔隙率特性,质量损失率及硬度下降最高;花岗岩因低孔隙率和高石英含量,劣化最轻微。【结论】多因子耦合显著加剧石质文物劣化,需针对石材特性采取差异保护措施。本研究成果可为石质文物老化机理分析提供一定的理论支撑。
[Objective]An endeavor was made to investigate the accelerated deterioration of stone cultural relics in Zhejiang Province under complex climatic conditions and to provide a scientific basis for formulating targeted conservation strategies.[Method]With gray sandstone,red sandstone,limestone,marble,and granite as the research objects,an accelerated laboratory aging experiment was designed to simulate the subtropical monsoon climate of Zhejiang Province,incorporating freeze-thaw cycles,salt crystallization immersion,and acid erosion treatments;the deterioration patterns of these five types of stone were systematically evaluated through mass tests,hardness tests,and scanning electron microscopy microstructural analysis.[Result]Red sandstone,due to its iron oxide cement and high porosity,exhibits the highest rates of mass loss and the most significant reduction in hardness;meanwhile,granite,characterized by low porosity and high quartz content,demonstrates the least deterioration.[Conclusion]Multi-factor coupling significantly accelerates the deterioration of stone cultural relics,necessitating differentiated conservation strategies based on their specific properties.The findings of this aging study thereby provide crucial data support for the analysis of their deterioration mechanisms.
