FRP lining yog ib txoj kev tswj xeb uas siv ntau thiab tseem ceeb tshaj plaws hauv kev tsim kho tiv thaiv xeb hnyav. Ntawm lawv, tes tso FRP siv dav vim nws yooj yim ua haujlwm, yooj yim thiab yoog tau. Nws tuaj yeem hais tias txoj kev tso tes tso suav rau ntau dua 80% ntawm FRP tiv thaiv xeb tsim kho. feem pua. Cov "peb cov ntaub ntawv tseem ceeb" resin, fiber thiab hmoov fiber hauv tes tso FRP yog lub cev 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 xeb ntawm FRP.
Raws li qhov sib txawv ntawm qhov chaw corrosive thiab nruab nrab, cov ntaub ntawv ntawm FRP kuj tseem yuav hloov pauv. Kev xaiv cov khoom siv thaum lub sijhawm tsim kho yog qhov tseem ceeb kom ntseeg tau tias cov khoom tiav FRP tuaj yeem hloov kho rau qhov chaw corrosive thiab nws lub zog. Yog li ntawd, kev xaiv cov ntaub ntawv txhawb nqa FRP yuav tsum tau txiav txim siab ua ntej kev tsim kho. Piv txwv li, cov ntaub ntawv txhawb nqa uas sawv cev los ntawm iav fiber yog cov ntaub ntawv fiber ntau tshaj plaws, uas tuaj yeem tiv taus feem ntau acid corrosion; txawm li cas los xij, lawv tsis tiv taus hydrofluoric acid thiab kub phosphoric acid corrosion. Siv polyester, polypropylene thiab lwm yam organic fiber ntaub thiab felt, koj tuaj yeem xaiv siv linen lossis degreased gauze, thiab qee cov khoom FRP xav tau corrosion tsis kam thiab conductivity, koj tuaj yeem xaiv cov ntaub ntawv carbon fiber. Hauv ib lo lus, kev xaiv tes tso FRP reinforced fiber yog ib qho kev txawj thiab kev paub uas cov thev naus laus zis tiv thaiv corrosion thiab cov neeg tsim qauv yuav tsum paub.
Hauv cov khoom FRP uas tau muab nplaum, feem ntau ntawm cov fibers reinforcing yog cov iav fibers, txawm tias nws yog daim ntaub, felt lossis xov paj. Qhov laj thawj tseem ceeb yog tias ntxiv rau qhov nqi, nws kuj muaj cov yam ntxwv zoo hauv qab no:
01 Tshuaj tiv thaiv
Cov ntaub fiberglass inorganic yuav tsis lwj, pwm lossis lwj. Lawv tiv taus feem ntau cov kua qaub tsuas yog hydrofluoric thiab kub phosphoric acid.
02 Ruaj khov
Cov xov iav fiber siv los ua cov ntaub iav tsis ncab lossis ntsws vim muaj kev hloov pauv ntawm huab cua. Lub npe hu ua elongation thaum tawg yog 3-4%. Qhov nruab nrab linear thermal expansion coefficient ntawm cov iav E yog 5.4 × 10-6 cm/cm/°C.
03 Kev ua haujlwm thermal zoo
Cov ntaub fiberglass muaj cov coefficient qis dua ntawm kev nthuav dav thermal thiab cov thermal conductivity siab dua. Fiberglass dissipates cua sov sai dua li asbestos lossis cov organic fibers.
04 Lub zog tensile siab
Cov xov fiberglass muaj qhov sib piv ntawm lub zog thiab qhov hnyav. Ib phaus ntawm cov xov fiberglass muaj zog ob npaug ntawm cov hlau hlau. Lub peev xwm los tsim lub zog ib txoj kev lossis ob txoj kev rau hauv cov ntaub ua rau muaj kev ywj pheej ntawm cov khoom siv kawg.
05 Kev tiv taus kub siab
Cov iav inorganic tsis kub hnyiab thiab tsis kub hnyiab thaum ci thiab kho kub ntau zaus hauv kev lag luam. Fiberglass yuav khaws tau li 50% ntawm nws lub zog ntawm 700 ° F thiab 25% ntawm 1000 ° F.
06 Tsis tshua muaj hygroscopicity
Cov xov fiberglass yog ua los ntawm cov fibers uas tsis muaj qhov ntxeem tau thiab yog li ntawd muaj kev nqus dej tsawg heev.
07 Kev rwb thaiv hluav taws xob zoo
Lub zog dielectric siab thiab qhov tsis tshua muaj dielectric tas mus li, nrog rau kev nqus dej tsawg thiab kev tiv taus kub siab, ua rau cov ntaub fiberglass zoo heev rau kev rwb thaiv hluav taws xob.
08 Kev hloov pauv ntawm cov khoom
Cov filaments zoo heev siv rau hauv fiberglass yarns, ntau yam xov paj loj thiab configurations, ntau hom weave, thiab ntau yam tshwj xeeb finishes ua fiberglass ntaub pab tau rau ntau yam kev siv kawg industrial.
09 tus nqi qis tus nqi qis
Cov ntaub fiberglass tuaj yeem ua haujlwm thiab sib piv rau cov nqi rau cov ntaub hluavtaws thiab cov ntaub fiber ntuj.
Yog li ntawd, cov iav fiber yog cov khoom siv FRP zoo tshaj plaws uas siv tes ua, uas pheej yig, pheej yig, thiab yooj yim rau kev siv. Nws yog ib qho ntawm cov ntaub ntawv siv dav tshaj plaws ntawm ntau cov ntaub ntawv txhawb nqa tam sim no.
