FRP corrosion product structure type definitions and Analysis

In steel, concrete or other substrate surface to prevent production of glass fiber reinforced plastic substrates in the media or the environment under the action of damage or deterioration, known as FRP corrosion. Commonly used FRP corrosion are: FRP Lining, glass flake lining, resin clay brick panels lining, self-leveling epoxy, epoxy powder coating, the substrate coated glass and steel. stone coated metal roofing tile

FRP corrosion product structure type:

1, the substrate

Mainly refers to the surface needs to corrosion materials, substrates and materials determine the quality status of anti-corrosion adhesive material selection and quality FRP corrosion.

2, the transition adhesive layer

Mainly used for FRP adhesion to substrates, ensuring FRP shear strength between the substrate concrete and steel surfaces commonly used materials are epoxy resins, vinyl resins.

3, the resin mortar layer

Mainly used to repair defects in the substrate surface layer and improving corrosion resistance fiberglass external load deformation, mainly resin mortar composition of the resin and filler material, filler material commonly used quartz powder, ceramic powder, talc, fumed silica, hollow glass beads and so on. stone coated steel roofing tile

4, fiberglass reinforced layer

Mainly used for coating of fiberglass reinforced and anti-leakage, and improve fiberglass coating mechanical properties are guaranteed to meet site conditions of stress and strain requirements. While strengthening FRP corrosion layer anti-leakage performance.

5, the outer protective layer

Mainly used to resist the external environment and the role of the media, usually by impermeable layers, resin-rich layer. Play an anti-corrosion, anti-leakage effect.
