Anti-corrosion characteristics of FRP products

FRP products have become the transmission medium of many industries due to their super anti-corrosion ability, but what does it rely on to achieve its unique characteristics. The structure of fiber-wound FRP products is divided into three parts: the inner lining layer, the structural layer and the outer protective layer. Among them, the resin content of the inner lining layer is high, usually more than 70%, and the resin content of the inner and outer resin-rich layers is as high as about 95%. Through the selection of the resin used in the inner lining, the FRP product manufacturers can make the FRP products have different corrosion resistance functions when transporting liquids, so as to meet different work needs; for the occasions that require external anti-corrosion, only the outer protective layer resin needs to be treated. Careful selection can also achieve the purpose of anti-corrosion of different surfaces.
FRP products are based on different corrosion environments. FRP product manufacturers can choose different anti-corrosion resins, mainly including: isophthalic unsaturated polyester resin, vinyl resin, bisphenol A resin, epoxy resin and furan resin, etc., according to The specific conditions are selected: for acidic environment, use bisphenol A resin, furan resin, etc.; for alkaline environment, use vinyl resin, epoxy resin or furan resin, etc.; for solvent-based application environment, use furan and other resins; When the corrosion of , salt, solvent, etc. is not very serious, you can choose the isophthalic resin with a relatively low price.
