The production of FRP on the surface of carbon steel, concrete or other substrates prevents the substrate from being damaged or deteriorated under the action of medium or environment, which is called FRP anticorrosion. Commonly used FRP anti-corrosion: FRP lining, glass flake lining, resin mortar brick lining, epoxy self-leveling, epoxy powder coating, substrate surface coated FRP.
FRP anti-corrosion product structure type:
1, the substrate
Mainly refers to the material that needs anti-corrosion on the surface. The quality and material of the substrate determine the selection of anti-corrosion bonding materials and the quality of anti-corrosion of FRP.
2. Transition bonding layer
It is mainly used for the bonding of FRP and substrate to ensure the shear strength between FRP and substrate. The commonly used materials for concrete and steel surface are epoxy resin and vinyl resin.
3. Resin mortar layer
It is mainly used to repair the surface defects of the substrate and improve the resistance to external load deformation of the FRP anti-corrosion layer. The resin mortar is mainly composed of resin and filler material. The commonly used filling materials are quartz powder, porcelain powder, talc powder, fumed silica, glass hollow. Microbeads, etc.
4, FRP reinforcement layer
It is mainly used for the reinforcement and anti-leakage effect of FRP anti-corrosion layer, improving the mechanical properties of FRP anti-corrosion layer and ensuring the stress and strain requirements of on-site working conditions. At the same time, the anti-leakage performance of the FRP anti-corrosion layer is strengthened.
5, the outer protective layer
It is mainly used to resist the external environment and media, and is usually composed of a barrier layer and a resin-rich layer. It has anti-corrosion and anti-leakage effects.
