the rust generated just now is well combined with the surface of the steel structure, and the phenomenon that the outer rust layer is loose and even falls off is caused due to the rust generated in front of the rust top generated behind the chemical reaction continuously reacting with the surface of the steel structure, so that the steel structure not only contains a large amount of phosphorus elements on the rusted surface, but also contains phosphorus elements with certain components on the surface of the rusted block contacted with metal.
The rust inhibitor adopted by the application contains a tannin component, and can well react with phosphoric acid on a rusted outer layer to generate a chemical conversion coating (HPO)4)2-Can be mixed with Fe3+Formation of complex ion Fe (HPO)4)-A blue-black protective film is formed on the surface of the steel structure, the protective film can effectively protect the surface of the steel structure from generating any scaling and corrosion within 168 hours,and tannic acid can also effectively prevent the phosphorus element from deeply diffusing in the corrosion of a steel structure after neutralizing the phosphorus element on the metal surface, and a good protection effect is also formed on the inner layer of the steel structure.
