Abstract

The corrosion resistance performance of prefabricated cabin is an important indicator assuring the 40 a service life of the prefabricated module cabin substation, so the selection of the anti-corrosion materials used is crucial.In this research, eight cabin protection materials(electro-galvanized coating, hot-dip galvanized coating, hot-dip galvanized thickened coating, zinc aluminum magnesium coating, fluorocarbon paint composite coating, graphene zinc-rich coating, hot-dip galvanized +polyurethane double layer coating and hot-dip galvanized +polyurethane superhydrophobic double layer coating) were selected to study the bonding performance and anti-corrosion performance between the substrate and these coatings/plating layers and had provided a reference for the selection of subsequent anti-corrosion materials for substations.The coating adhesion test results showed that all coating/plating materials had good bonding properties with the substrate; the neutral salt spray(NSS) test results showed that the hot-dip galvanized and hot-dip galvanized magnesium-aluminum process showed better resistance to corrosion than the electro-galvanized sheet.The hot-dip galvanized +polyurethane double-coating process showed better corrosion resistance.In addition, if the surface is given hydrophobic properties, its corrosion resistance can be greatly improved and it also has a certain self-cleaning function.
