AI Technical Summary
Technical Problem
I-beams are susceptible to corrosion due to environmental factors in electromagnets, which affects their performance.
Method used
A combination of hydrophobic and hydrophilic coatings is used to form a three-layer coating structure of hydrophobic-hydrophilic-hydrophobic. The hydrophobic coating is mainly composed of epoxy resin with a silicon dioxide layer coated with graphene oxide. The hydrophilic coating uses hydrophilic modified epoxy resin emulsion and modified adsorbent. The three layers work together to prevent rust.
Benefits of technology
It effectively reduces the contact between I-beams and water molecules, improves rust prevention, and reduces corrosion. It is suitable for the surface of I-beams used in electromagnets.
