The basic components of pultrusion FRP profiles are resin and glass fiber (including cloth, felt, etc.). It is based on fiber (including glass fiber, carbon fiber, organic fiber, and other metal, nonmetal fiber) as reinforced material. Resin (mainly epoxy resin. Polyester resin, phenolic resin) as a binder, supplemented by other auxiliary materials (main auxiliary materials: Release agent, curing agent, catalyst, sealing agent, UV light stabilizer, clean water, gel, etc.) of composite, it has the corrosion-resistant, high strength, the proportion of small, low moisture absorption, low extension, and good insulation, and a series of good features, there are many kinds of FRP pultrusion profiles, FRP pipe, FRP pipe, FRP rectangular pipe, FRP rods, glass steel beams.
Application field of pultrusion profiles
1. Petrochemical industry: Because FRP pultrusion profiles, excellent corrosion resistance in the petroleum, chemical industry for electric and pneumatic circuits of hungry stents, generator radiator, corridor, stair and handrail, operation platform, oil tank, switchboards and distribution, drain and drainage system, berth identification marks and underwater identification marks, the good sucker rod, tower packing of stents, filter plate, etc.
2. Power: Because of the good performance of the FRP pultrusion profile machine, pultrusion profile is used as an insulating supporting member. High voltage cable bridge, antenna column, high voltage current operating rod.
3. Urban rail three rail protection cover and bracket, insulation support components, antenna column, high voltage cable bridge, high voltage power supply operation bar, generator loose handrail, operation platform, aisle, storage tank, distribution board and distribution room, Drainage system, berths and submarine identification marks, as pressure bar in trains and automobiles, corner plate, highway guardrail, sound-absorbing board, anti-dazzle board, filler bracket in the tower, filter plate bracket, frame material of cold storage, etc.
FRP pultrusion profiles have advantages: FRP product’s quality stability. Enhanced material content can be adjusted according to requirements, can adjust the longitudinal strength and transverse strength of products, for different use requirements, can produce products with complex section shape, can be used in some occasions, FRP products integrity is good.
