Selective removing method for gypsum weathering layer on surface of stone relics and stone materials
The present invention provides a selective removing method for the gypsum weathering layer on the surface of stone relics and stone materials. According to the method, in an aqueous solution, a co-solvent is used to dissolve and convert the harmful gypsum weathering layer on the surface of stone relics and stone materials, and the finally produced insoluble salt stays in the co-solvent. According to the present invention, the gypsum weathering layer removing is complete, no chemical residue exists, the removing is selective, the dissolving and conversion reaction can be automatically terminated after completing the gypsum weathering layer removing, and the stone material substrate is not damaged.
