We know that the application range of FRP is diverse, involving almost all aspects of our work and life, such as chemical containers, water supply pipes, sewage pipes, trash cans, park sculptures, etc. FRP products are not easy to classify, but can be divided into:
1). According to the molding process, it is divided into: hand lay-up, pouring, molding, winding and pultrusion products, etc.;
2). According to the base material, it is divided into: polyester, epoxy resin and phenolic FRP products, etc.;
FRP products have good building properties, which are embodied in:
1). Chemical resistance
FRP has good anti-microbial and acid and alkali resistance, organic solvent and seawater corrosion ability, especially suitable for chemical construction, underground construction and hydraulic construction and other projects.
2). Sound insulation
Although the sound insulation performance of FRP is not ideal, it has the effect of attenuating the transmission of vibration and sound. The specially designed sandwich structure can achieve the double-layer effect of sound insulation and heat insulation.
3). Water permeability and water absorption
FRP has very low hygroscopicity and is impermeable to water, and can be used for waterproofing, water supply and drainage in construction projects.
4). Good decoration
The surface finish of FRP can be made into various bright colors, as well as different patterns and patterns, suitable for making various decorative panels, large-scale reliefs and handicrafts, etc.
