Problems solved by technology

[0002] The types of grid corrosion are not only diverse, but because their environment is often accompanied by high-voltage electromagnetic environment characteristics, some corrosion behaviors have obvious grid characteristics, such as DC electrolytic corrosion faced by the ground electrode of high-voltage DC transmission projects in the grid, and some equipment is exposed to strong electromagnetic fields and natural environments. Corrosion problems under the coupling of multiple factors, such as corrosion, further increase the difficulty of grid corrosion protection

Embodiment 1

[0018] A method for preparing a superhydrophobic coating based on an electrodeposition method, comprising the following steps: 1. Electrode pretreatment: the steel electrode is polished on a polishing paper, and then the polished steel electrode is cleaned with laboratory-made deionized water Clean, then polish with aluminum powder to further remove a large amount of oil, and then rinse again with deionized water made in the laboratory. After rinsing, put it in a beaker filled with ethanol and put it in an ultrasonic cleaner Ultrasound for 15 minutes, then cleaned with a large amount of deionized water, dried, sealed with a parafilm, and set aside; 2. Preparation of electrolyte: First, weigh 30 mg of graphene and dissolve it with 30 ml of deionized water. Seal the sealing film, put it into an ultrasonic cleaner and perform ultrasonication for 1 hour, until the graphene is in a pulverized state, and make a graphene aqueous dispersion for use; 3. Electrodeposition of graphene: ad...
