Frp ob sab phlu yog ib qho kev tswj hwm thiab tseem ceeb tshaj plaws hauv kev tswj hwm hauv cov haujlwm hnyav-xeb. Ntawm lawv, tes nteg frp yog dav siv vim nws txoj haujlwm yooj yim, yooj yim thiab hloov tau. Nws tuaj yeem hais tau tias txhais tes kab txheej txheej rau ntau dua 80% ntawm Frp los tiv thaiv corrosion corrosion. ua feem. "Peb cov ntaub ntawv loj" Resin, fiber ntau thiab hmoov fiber ntau hauv kev paub txog kev paub txog lub sijhawm ntev ntawm kev ua xeb ntawm FRP.
Raws li qhov sib txawv ntawm kev thaj chaw corrosive thiab nruab nrab, cov khoom ua haujlwm ntawm FRP tseem yuav hloov pauv. Cov lus xaiv cov khoom siv yog qhov tseem ceeb ntawm cov khoom qav ua tiav tuaj yeem hloov kho kom haum rau txoj kev xeb thiab nws cov kav ntev. Yog li ntawd, xaiv ntawm FRP Txuas Txuas Cov Khoom Siv Lub Zog yuav tsum raug txiav txim ua ntej kev tsim kho. Piv txwv li, lub zog txhawb cov khoom los ntawm cov iav fiber ntau yog cov ntaub ntawv fiber ntau tshaj plaws, uas tuaj yeem tiv thaiv feem ntau acid corrosion; Txawm li cas los xij, lawv tsis tiv taus hydrofluoric acid thiab kub phosphoric acid acid acidosion. Siv polyester, polyproter thiab lwm cov ntaub organic fiber ntau thiab cov khoom siv frp, koj kuj tseem tuaj yeem xaiv cov ntaub ntawv fiber ntau. Hauv ib lo lus, kev xaiv ntawm txhais tes nteg-up fiberfled Fiber yog kev txawj thiab kev paub txog kev tiv thaiv corrosion thiab cov tsim qauv yuav tsum muaj tswv.
Nyob rau hauv cov frp cov khoom lag luam, feem ntau ntawm kev txhawb nqa cov fibers yog iav fibers, txawm hais tias nws yog daim ntaub, muaj ntaub qhwv ntsej muag. Lub ntsiab yog vim li cas yog tias ntxiv rau tus nqi sib ntxiv, nws tseem muaj cov yam ntxwv zoo hauv qab no:
01 Tshuaj Txhuam Kuj
Inoracicic fiberglass textile fibers yuav tsis rot, pwm lossis tsis zoo. Lawv tiv taus feem ntau cov acids tsuas yog hydrofluoric thiab kub phosphoric acid.
02 tshuav tsis tau
Cov xov tooj iav fiber ntau siv los ua cov iav cov ntaub tsis ncab lossis ntsws vim hloov pauv ntawm cov huab cua. Noominal elongation thaum so yog 3-4%. Qhov nruab nrab linear thermal expansion coefficient ntawm bulk E-iav yog 5.4 × 10-6 cm / ° C.
03 Kev ua tau zoo thermal
Fiberglass ntaub muaj cov coefficient ntawm thermal nthuav thiab siab dua thermal conductivity. Fiberglass dissipates kub sai dua li asbestos lossis organic fibers.
04 lub zog tensile lub zog
Cov xov paj fiberglass muaj lub zog siab-rau-qhov hnyav piv. Ib phaus ntawm cov xov paj fiberglass yog ob zaug kom muaj zog npaum li steel hlau. Lub peev xwm rau cov engineer unidirectional lossis bidirectional lub zog rau hauv cov ntaub zoo nce qhov yooj ntawm kev siv cov khoom kawg.
05 Kev Kub Kub Kub Kuj
Inorganic iav cov fibers tsis hlawv thiab yog qhov tseem ceeb tiv thaiv kab mob siab thiab kho kev kho kom kub feem ntau ntsib hauv kev lag luam kev lag luam. Cov iav fiberglass yuav khaws tau txog 50% ntawm nws lub zog ntawm 700 ° F thiab 25% ntawm 1000 ° F.
06 tsawg hygroscopicity
Cov xov paj fiberglass yog ua los ntawm cov tsis muaj qhov ntxig fibers thiab yog li ntawd muaj cov av noo tsawg heev.
07 Kev Rwb Thaiv Hluav Taws Xob
Kev ua kom muaj zog thiab lub zog tsis muaj zog, nrog rau cov dej nqus dej tsawg thiab kub ua kom zoo nkauj rau hluav taws xob rwb thaiv tsev.
08 cov khoom lag luam yooj yim
Cov lus zoo heev uas tau siv hauv cov xov paj nrog cov xov paj, ntau yam ntawm weave, thiab ntau cov kev sib tw ua tiav, thiab ntau cov kev ua tiav tshwj xeeb ua rau ntau yam kev lag luam muaj kev lag luam xaus.
09 tus nqi pheej yig tsawg
Fiberglass ntaub tuaj yeem ua txoj haujlwm thiab muaj sib piv hauv cov nqi hluavtaws thiab cov khoom siv fiber ntau.
Yog li ntawd, iav fiber yog qhov zoo tshaj plaws ntawm tes nteg-up frp qhov cuab yeej siv, 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 cov ntaub ntawv uas cuam tshuam rau tam sim no.
