Influence of Different Acid on the Interfacial Compatibility between Rusted Steel and Water-Based Coating

We aimed to improve the corrosion resistance of transmission network cabinet equipment in high temperature and humidity environment. In this paper, using acid modified acrylic acid as the main component, the composite conversion agent was obtained by adding phosphoric acid phytic acid and other comp...
