Beschreibung
Zusammenfassung:	The invention discloses a method for treating a metal surface after a fire by using ethylene diamine tetraacetic acid tetrasodium salt, and belongs to the field of metal material repair, and the treatment method comprises the following specific steps: (1) collecting and cleaning metal parts influenced by a disaster situation; (2) the cleaned metal part is put into reducing gas to be reduced; (3) preparing a Na4EDTA (Ethylene Diamine Tetraacetic Acid) solution to soak the metal part; (4) collecting image information of the metal part and spraying a protective coating; according to the invention, real-time monitoring and adjustment of coating application are realized, the precision and efficiency of construction are improved, and a metal part can resist corrosion and oxidation for a longer time, so that the cost of subsequent maintenance and repair is reduced, and meanwhile, accurate control of the treatment process is realized to meet the requirements of different metals and applications. 本发明公开了乙二胺四乙酸四钠在火灾后金属表
