It is said that glass fiber reinforced plastic material is resistant to corrosion, and its pitting resistance mainly depends on where? First of all, FRP is mainly made of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin as the matrix.
Its corrosion resistance mainly depends on the performance of the resin, because it is usually due to the good corrosion resistance of FRP itself, so many common products and equipment in life are made of FRP. For example, glass tempered ponds, glass fiber cooling towers, glass fiber reinforced plastic water tanks, glass fiber reinforced plastic pipes, etc., are usually used for waste heat wastewater in production and life, and are used to treat waste heat wastewater in life. Due to year-round exposure to certain contaminants, the equipment was tested for extensive corrosion resistance. From the beginning of research and development, FRP materials have been widely used in various equipment.
However, the corrosion resistance of FRP materials is mainly due to its reasonable selectivity and the crosslinking density of the resin. So, what are the three main factors of temperature, concentration and resin in the whole process? Actually it is determined on a case-by-case basis. The properties are also different for different resins. In terms of corrosion resistance: the solubility of phenolic acid is better, the alkali resistance of amine curing is better, the comprehensiveness of polyester is better, and the corrosion resistance of different resins is different.
