盐的风化是遗址和坟墓等文化遗产的主要问题，而通过涂抹海水淡化是有效去除污染盐的一种有趣的潜在方法。预测可实现的脱盐程度是非常重要的。然而，现有的许多考虑盐水在多孔材料中运移的模型都是基于纯水理论建立的。为了了解盐水在多孔材料中的流动情况，我们采用降头法测定了凝灰岩的盐水渗透性。我们发现凝灰岩的渗透性除了受盐水的密度和动态粘度的影响外，还受其他因素的影响。
Salt weathering is a major concern for cultural heritages such as ruins and tombs, and desalination by poulticing is an interesting potential method to efficiently remove contaminating salt. Predicting the degree of achievable desalination is very important. However, many existing models used to consider saline water transport in porous materials have been developed based on the theory of pure water. To understand saline water flow in porous materials, we determined the saline water permeability of a tuff stone by the falling-head method. We found that the permeability of the tuff stone was affected by factors other than the density and dynamic viscosity of the saline water.
