针对盐害治理目前常用的表面贴敷法、浸泡法等易造成硅酸盐材料二次破坏的问题，采用新型的雾化水汽控盐-脱盐法，借助激光粒度分析仪、X射线衍射仪、可见短波红外高光谱成像系统和离子色谱仪等手段，检测了对表面即将发生盐害的试样治理前后内部盐分的分布变化。结果表明：雾化水汽进入试样后对试样的润湿面为以喷雾点为中心的半球面，试样浅表层的盐分被运移到半球状润湿面外，得到了雾化水汽法控盐的路线，初步验证了雾化水汽法预防性治理硅酸盐质材料盐害的可行性。

The salt control and desalination for treating the secondary damage of silicate materials caused by sticking ointment and soaking method commonly used in salt damage control were investigated by a spraying atomized water vapor method. The salt distributions in the samples before and after treatment were analyzed by laser particle size analysis, X-ray diffraction, visible shortwave infrared hyperspectral imaging analysis and ion chromatograph. The results show that after the atomized water vapor enters the sample, the area where the sample is wetted is a hemisphere centered on the spray point, and the salt in the superficial layer of the sample is transported to the outside of the hemispherical wetting area. Also, the route of controlling the salt distribution by atomized water vapor was proposed, and the feasibility of preventive treatment of salt damage in silicate material was preliminarily verified.
