Aerial algal can easily propagate on the surface of open-air stone cultural relics. The reproduction of algal will induce the formation of biofilm on the surface of the stone, which will not only make the stone discolored and crusted, but also secrete bio-acid to corrode the stone, which will make the lettering and patterns on the surface of stone blurred and affect the value and safety of cultural relics. The purpose of this study is to clarify the difference of algal growth on the surface of stone carvings with different orientations and its main influencing factors in Jiangnan area of China and to predict the propagation speed of algal on the surface of stone carvings under typical climatic conditions in Jiangnan area. In this study, the difference of algal growth and the main influencing factors on different surfaces were discussed through field investigation and the algal reproduction prediction model coupled with heat and moisture transfer model. The results show that the growth of algal is mainly affected by the temperature of the material surface. In summer, the algal growth in the horizontal plane and the western vertical plane is inhibited by high temperature. Generally, the north vertical plane has the most algal growth, while the west vertical plane has the least algal growth. The growth of algal on the inclined surface is more than that on the horizontal surface due to the less solar radiation. Rainwater promotes the growth of algal, and the amount of algal growth in three years in the case of rain is about ten times than that without rain. In addition, when hygroscopicity of the algal is considered, the growth of hygroscopic algal is faster than that of non-hygroscopic algal. [ABSTRACT FROM AUTHOR] |
