1. Fiberglass reinforced plastic products have become a transmission medium for many industries due to their strong corrosion resistance, but what they rely on to achieve their unique characteristics? The construction of fiberglass reinforced plastic products is divided into three parts: inner lining layer, structural layer, and outer maintenance layer. Among them, the resin content of the inner lining layer is high, usually above 70%, and the resin content of the resin rich layer on the inner and outer surfaces is as high as about 95%. By selecting the resin used for the lining, fiberglass products can have different corrosion resistance when delivering liquids, thus meeting different work requirements; For places that require external anti-corrosion, simply maintaining the resin layer externally can also achieve different application purposes of external anti-corrosion.
2. Fiberglass reinforced plastic products can choose different anti-corrosion resins based on different corrosion environments, mainly including meta benzene unsaturated polyester resin, vinyl resin, bisphenol A resin, epoxy resin, and furan resin. Depending on the specific conditions, bisphenol A resin, furan resin, etc. can be selected for acidic environments; For alkaline environments, choose vinyl resin, epoxy resin, or furan resin, etc; For solvent based application environments, choose resins such as furan; When the corrosion caused by acids, salts, solvents, etc. is not very severe, cheaper meta benzene resins can be selected. By selecting different resins for the inner lining layer, fiberglass products can be widely used in acidic, alkaline, salt, solvent and other working environments, exhibiting good corrosion resistance.
