FRP hauv ob sab phlu yog ib txoj hauv kev zoo tshaj plaws thiab tseem ceeb tshaj plaws ntawm kev tiv thaiv corrosion.Ntawm lawv, tes nteg-up FRP tau dav siv vim nws txoj haujlwm yooj yim, yooj yim thiab yoog raws.Nws tuaj yeem hais tias txhais tes lay-up txoj kev suav nyiaj ntau dua 80% ntawm FRP los tiv thaiv corrosion.kev faib ua feem.Cov "peb cov ntaub ntawv tseem ceeb" resin, fiber ntau thiab hmoov fiber ntau hauv tes-ntev FRP yog cov pob txha ntawm FRP, txhawb nqa lub zog ntawm FRP system, thiab yog ib feem tseem ceeb ntawm kev paub txog cov txiaj ntsig ntev ntawm kev tiv thaiv corrosion ntawm FRP.

Raws li qhov sib txawv ntawm corrosive ib puag ncig thiab nruab nrab, cov khoom siv ntawm FRP kuj tseem yuav hloov.Kev xaiv cov khoom siv thaum lub sij hawm tsim kho yog qhov tseem ceeb los xyuas kom meej tias cov khoom tiav FRP tuaj yeem hloov mus rau qhov chaw corrosive thiab nws cov kav ntev.Yog li ntawd, kev xaiv ntawm FRP cov ntaub ntawv txhawb nqa yuav tsum tau txiav txim siab ua ntej kev tsim kho.Piv txwv li, cov ntaub ntawv txhawb zog sawv cev los ntawm iav fiber ntau yog cov khoom siv fiber ntau, uas tuaj yeem tiv taus cov kua qaub feem ntau;Txawm li cas los xij, lawv tsis tiv taus hydrofluoric acid thiab kub phosphoric acid corrosion.Siv polyester, polypropylene thiab lwm cov organic fiber ntau daim ntaub thiab muaj kev xav, koj tuaj yeem xaiv siv linen lossis degreased gauze, thiab qee cov khoom FRP xav tau kev tiv thaiv corrosion thiab conductivity, koj tuaj yeem xaiv cov ntaub ntawv carbon fiber.Nyob rau hauv ib lo lus, kev xaiv ntawm tes nteg-up FRP reinforced fiber yog ib qho kev txawj thiab kev paub taw tes uas anti-corrosion technology thiab designers yuav tsum paub.

Nyob rau hauv pasted FRP cov khoom, feem ntau ntawm cov reinforcing fibers yog iav fibers, txawm nws yog ntaub, ntaub los yog xov paj.Lub ntsiab yog vim li cas ntxiv rau tus nqi zoo, nws kuj muaj cov yam ntxwv zoo hauv qab no:
01 Tshuaj tiv thaiv
Inorganic fiberglass textile fibers yuav tsis rot, pwm los yog deteriorate.Lawv tiv taus cov acids feem ntau tsuas yog hydrofluoric thiab kub phosphoric acid.
02 Dimensionally ruaj khov
Cov iav fiber ntau siv los ua cov ntaub iav tsis ncab lossis ntsws vim qhov hloov pauv hauv huab cua.Qhov nominal elongation ntawm so yog 3-4%.Qhov nruab nrab linear thermal expansion coefficient ntawm bulk E-iav yog 5.4 × 10-6 cm / cm / ° C.
03 Kev ua haujlwm zoo thermal
Fiberglass fabrics muaj qis coefficient ntawm thermal expansion thiab ntau dua thermal conductivity.Fiberglass dissipates tshav kub sai dua asbestos los yog organic fibers.
04 High tensile zog
Fiberglass yarn muaj lub zog-rau-hnyav piv.Ib phaus ntawm fiberglass yarn yog ob npaug zog li steel hlau.Lub peev xwm los engineer unidirectional lossis bidirectional lub zog rau hauv cov ntaub zoo heev ua rau kom yooj yim ntawm cov khoom siv kawg.
05 Siab kub tsis kam
Inorganic iav fibers tsis kub hnyiab thiab yog qhov tseem ceeb tiv thaiv rau lub siab ci thiab kho qhov kub thiab txias feem ntau ntsib hauv kev lag luam.Fiberglass yuav khaws li 50% ntawm nws lub zog ntawm 700 ° F thiab 25% ntawm 1000 ° F.
06 Tsawg hygroscopicity
Fiberglass yarns yog ua los ntawm non-porous fibers thiab yog li ntawd muaj tsawg heev noo noo nqus.
07 Zoo hluav taws xob rwb thaiv tsev
Lub zog dielectric siab thiab tsis tshua muaj dielectric tsis tu ncua, nrog rau kev nqus dej tsawg thiab kub tsis kam, ua fiberglass fabrics zoo heev rau hluav taws xob rwb thaiv tsev.
08 Cov khoom yooj yim
Cov filaments zoo heev siv hauv fiberglass yarns, ntau qhov ntau thiab tsawg thiab kev teeb tsa, ntau hom kev sib txawv, thiab ntau qhov tshwj xeeb ua tiav ua fiberglass fabrics pab tau rau ntau yam kev lag luam kawg.
09 tus nqi qis qis
Fiberglass fabrics tuaj yeem ua txoj haujlwm thiab sib piv rau tus nqi rau cov khoom siv hluavtaws thiab ntuj fiber ntau.

Yog li ntawd, iav fiber ntau yog ib qho zoo tagnrho tes nteg-up FRP cov khoom siv ntxiv, uas yog kev lag luam, pheej yig, thiab yooj yim rau kev khiav lag luam.Nws yog ib qho ntawm cov khoom siv dav tshaj plaws ntawm ntau cov ntaub ntawv txhawb nqa tam sim no.
