摘要: 采用pH值分别为5.6,4.5和3.0的人工模拟酸雨,在实验室条件下对具有相同成分的石材进行降雨侵蚀实验,测定了不同pH值下的腐蚀速率.同时,运用XRD和SEM分析酸雨腐蚀的规律.结果表明:酸雨侵蚀首先发生在颗粒间隙处;pH值愈低,腐蚀愈严重;酸雨腐蚀后,石材表面碳酸钙流失严重,其它成分相对富集在表面,而且改变了其原来的形貌.

Abstract: In order to study the effects of acid rain on carved stone,simulated precipitation erosion experiments were carried out in the laboratory by applying artificially prepared acid rain with pH 5.6,4.5 and 3.0 onto stone materia.Rates of deterioration for different pH were obtained.Meanwhile,deterioration process was monitored with XRD and SEM.The results of experiments indicated that deterioration started among gain boundaries of crystals,and the deterioration increased with the decrease of pH.Calcium carbonate on the surface lost severely with relative enrichment of other components,which resulted in the changes on initial appearance.
