AI Technical Summary

Technical Problem

When used in high humidity and high salt spray environment, the fiber tensile strength decreases, fatigue resistance decreases, and service life shortens.

Method used

The composite coating structure is adopted, including a hydrophobic wear-resistant layer, a barrier layer and a fill layer. It uses modified polyurethane, fluoroelastomer, nanoZnO, nanomontmorillonite and nanographene to form a dense barrier and conductive network to block salt spray and water molecules penetration, and enhance the wear resistance and corrosion resistance of the fibers.

Benefits of technology

It extends the service life of the aramid rope conveyor belt in high humidity and high salt spray environments, improves the fiber's salt spray corrosion resistance and wear resistance, and enhances fatigue resistance.
