Cov downsides ntawm cov rebarlass rebar
Iav yas tus rebar (GFRP, lossis khob fiber ntau txhawb nqa yas) yog cov khoom siv sib xyaw ua ke, suav nrog cov iav ntxiv rau qee cov ntawv thov kev teeb tsa. Txawm hais tias nws ntau qhov zoo, muaj qee qhov tsis zoo:
1. Tsis zoo Alkali Kuj:Cov iav fibers muaj kev cuam tshuam rau kev yaig hauv ib puag ncig alkaline feem ntau yog alkaline, uas yuav cuam tshuam rau cov khoom sib txuas lus thiab ntev ntev ntawm cov kab tuav.
2. Qis Qis Txiaj Ntsig Zog:Fiberglass Reinfercing Cov Nqis Muaj qis dua shear lub zog piv tau piv rau cov kab hlau zoo tib yam, uas txwv lawv siv hauv cov txheej txheem txheej txheem uas siab dua shear tsis kam.
3. Cov duci tsis zoo:Iav yastus rebar yog tsis yog ua kom zoo li cov hlau sib txuas, uas txhais tau tias lawv tuaj yeem tiv taus lawv lub zog kawg, thiab tsis xaiv qhov kev xaiv zoo tshaj plaws rau qee cov seismic tsim.
4. Tsis zoo ua tau zoo ntawm qhov kub:Lub zog ntawmiav yastus rebar txo qis nyob rau hauv qhov chaw kub ib puag ncig, uas txwv lawv siv hauv cov ntawv thov uas lawv yuav raug rau qhov kub siab.
5. Cov teeb meem nqi: Thaum iav yastus rebar tuaj yeem raug nqi-txuag hauv qee kis, hauv lwm tus neeg tuaj yeem kim dua li cov khoom siv uas muaj txiaj ntsig zoo ntawm cov khoom, kev tsim khoom thiab kev teeb tsa.
6. Cov Qauv Qauv thiab Tsim Qauv: Daim ntawv thov ntawmFiberglass Reinfercing Cov Nqis yog tus tshiab piv rau cov kev txhawb nqa hlau hlau ntxiv, thiab tsim cov qauv tshwj xeeb yuav tsis paub tab txaus, thiab cov qauv txwv tsis pub muaj cov lus qhia thiab cov lus qhia rau lawv siv.
7. Kev Siv Khoom Siv:Txhim kho thiab kev tsim kho ntawmiav yastus rebar Yuav tsum muaj kev txawj tshwj xeeb thiab kev ceev faj, uas yuav ua rau muaj kev nyuaj ua haujlwm thiab raug nqi.
8. Lub tshuab kho cov teeb meem ntawm Anchoring: Lub thauj mus los ntawmiav yastus rebar Yuav ua tau ntau qhov nyuaj tshaj li ntawm kev txhawb nqa cov kab uas muaj kev txhawb nqa, yuav tsum tau ua tshwj xeeb rau Anchoring tsim qauv thiab txoj kev tsim qauv.
Dua li ntawm cov teeb meem no,Iav Fiber ReBar tseem yog qhov kev xaiv txaus nyiam rau qee cov ntawv thov tshwj xeeb, tshwj xeeb tshaj yog qhov chaw tsis muaj sib nqus, xeb-corrosion-resistant lossis lub teeb yuag.
Qhov zoo ntawm fiberglass rebar
GFRP muaj cov txiaj ntsig hauv qab no tshaj cov sib txuas hlau sib txuas (feem ntau yog cov pob roj carbon ntau):
1. Corrosion Kuj:GFRP Bars Tsis txhob xeb, yog li lawv kav ntev dua nyob rau hauv ib puag ncig hnyav xws li cov tubrog nkoj muaj sia, tshuaj lom neeg lossis cov av noo siab.
2. Cov hlau tsis muaj zog:Frp rebar Yog tsis muaj kev sib nqus, uas ua rau lawv muaj txiaj ntsig hauv cov xwm txheej uas xav tau, xws li MRI chav nyob hauv tsev kho mob lossis nyob rau cov khoom siv tshuaj ntsuam xyuas geological.
3. Lub teeb:Fiberglass rebar Muaj ntau dua qis dua cov hlau sib txuas, uas ua rau lawv yooj yim dua thiab nruab thaum lub sijhawm tsim kho thaum tseem txo qhov hnyav ntawm cov qauv tag nrho.
4. Hluav taws xob rwb thaiv tsev:Iav Fiber Reintermolmolmolmbited Polymer Bars Yog insulators ntawm hluav taws xob, yog li lawv tuaj yeem siv rau cov qauv uas xav tau cov rwb thaiv tsev hluav taws xob, xws li cov qauv kev txhawb nqa rau cov kab hluav taws xob.
5. Tsim kev tsim qauv:GFRP Bars Yuav tuaj yeem kho cov qauv thiab qhov loj uas xav tau, muab tus tsim qauv tsim kev ywj pheej ntau dua.
6. Durability: nyob rau hauv txoj cai xwm txheej,Fiberglass Reinfercing Cov Nqis Muaj peev xwm muab cov sij hawm ntev ntev, txo kev txij nkawm thiab tus nqi hloov.
7. Kev qaug zog: Fiberglass rebars Muaj cov nkees nkees ua hauj lwm, uas txhais tau tias lawv tswj lawv qhov kev ua tau zoo nyob rau hauv cov khoom siv uas raug rau cov teeb meem cyclic, xws li txuas hniav thiab kev loj.
8. Cov coefficient ntawm thermal expansion:Fiberglass rebars Muaj cov coefficient ntawm thermal expansion, uas muab rau lawv zoo dua seem ruaj khov nyob rau hauv ib puag ncig nrog loj kub hloov.
9. Txo cov npog khawm: vim tiasfiberglass rebars Tsis txhob xeb, cov tuab ntawm cov vaj tse npog tuaj yeem raug txo nyob hauv qee qhov kev tsim qauv, txo qhov hnyav thiab tus nqi ntawm cov qauv.
10. Txhim kho cov qauv qauv txheej txheem: hauv qee cov ntawv thov,fiberglass rebars tuaj yeem ua haujlwm tau zoo dua nrog cov pob zeb ua kom zoo thiab txhim kho cov kev ua tau zoo ntawm cov qauv, xws li hauv kev khoov thiab shear tsis kam.
Dua li no cov kev ua tau zoo,fiberglass rebars Kuj muaj lawv cov kev txwv, raws li tau hais ua ntej. Yog li ntawd, thaum xaiv siv Iav Fiber cov rebars, Nws yog ib qho tsim nyog kom muaj kev nkag siab txog qhov xav tau ntawm cov qauv thiab cov txheej txheem ib puag ncig.
