顺德、肇庆地区红砂岩文物的风化机理及其保护措施

中国有着丰富的文化遗产,其中绝大部分为石质文物,而在石质文物中红砂岩文物又占了很大的一部分。大量的石质文物风化破坏的情况十分严重。本课题主要对广东顺德、肇庆地区的红砂岩文物进行实地考察和取样,在实验室内采用偏光显微镜、傅立叶红外光谱、X-射线衍射、离子色谱方法对其进行实验分析。结果表明：顺德肇庆地区的红砂岩文物风化严重,在风化过程中有多种因素共同作用,既有物理作用,也有各种化学反应的存在,生物对文物的风化也起了重要的作用。本文在研究了这些地区的红砂岩文物的风化情况之后,根据风化的机理提出了相应的保护措施。

Weathering Mechanism and Protection Measures of Red Sandstone Heritage

China leaves lots of precious cultural heritage,narrating the old history and accumulation of culture.Most of the material heritage is stone relic,while red sandstone relic takes the main part.Because of lack of protection,the efflorescent damages to the stone relic are very serious.And the research of stone relic protection has almost not yet started.In this study,exploration and sampling of red sandstone in Shunde and Zhaoqing city,Guangdong province are managed.And then the materials are analyzed by the modern experimen-tal equipment in the laboratory.The main research methods are polarizing microscopic analysis,fourier infrared spectroscopic analysis,X-rays diffracting analysis,and ion chromatogram analysis.The findings of the research are： the efflorescence of the red sandstone is serious,and the efflorescence course consists of the effect of conjunct factors,including physical effects and chemical reactions,mean-while creatures also play an important role in the course.After the study of efflorescence of the red sandstone in these areas,the author lists the corresponding safeguard and believes that the protection of the stone relic should begin from the source of efflorescence.
