Why can FRP profiles prevent corrosion?
The corrosion resistance of FRP profiles mainly depends on the resin. The less functional groups in the resin, the less active and the more stable the resin. For example, ester groups are easy to be dissolved by alkaline water, amide groups are easy to be dissolved by acid, polar bonds such as C-O and C-N are easy to hydrolyze, and C-H is easy to be oxidized. These are chemical actions. It is also related to glass fiber, filler, curing agent and surface treatment agent. In addition to chemical or physical effects on glass fiber and resin, chemical media also play a role in its interface bonding, leading to the destruction of FRP properties. Therefore, reasonable selection of materials and improvement of resin crosslinking density are the key to manufacturing corrosion resistant FRP. The three factors, temperature, concentration and resin type, which play a dominant role, can only be determined according to the specific situation.
What is the material of FRP profile
There are many kinds of FRP pultrusion profiles, including FRP round tubes, FRP square tubes, FRP rectangular tubes, FRP round rods, and FRP I-beams. The basic components of pultruded FRP profiles are resin and glass fiber (including cloth, felt, etc.). It uses fiber (including glass fiber, carbon fiber, organic fiber and other metal and non-metallic fibers) as reinforcement materials, and resin (mainly epoxy resin, polyester resin, phenolic resin) as binder, It is compounded with other auxiliary materials (main auxiliary materials: release agent, curing agent, catalyst, sealing agent, UV light stabilizer, mold cleaning water, gel coat, etc.). It has a series of excellent characteristics such as high temperature resistance, corrosion resistance, high strength, small specific gravity, low moisture absorption, small extension and good insulation
