Cov iav fiber ntau muaj cov khoom zoo heev thiab tau siv dav hauv ntau lub teb.Nws yog ib yam khoom uas tsis yog-hlau uas tuaj yeem hloov tau hlau.Vim nws txoj kev loj hlob zoo, cov tuam txhab iav fiber ntau tau tsom mus rau kev tshawb fawb txog kev ua haujlwm siab thiab kev ua kom zoo ntawm iav fiber ntau.
1 Txhais cov iav fiber ntau
Cov iav fiber ntau yog ib yam khoom siv tsis zoo uas tsis yog xim hlau uas tuaj yeem hloov tau hlau thiab muaj kev ua tau zoo heev.Nws yog npaj los ntawm kos molten iav rau hauv fibers los ntawm kev ua ntawm sab nraud quab yuam.Nws muaj cov yam ntxwv ntawm lub zog siab, siab modulus thiab qis elongation.Thaum tshav kub kub tsis kam thiab compressibility, loj thermal expansion coefficient, siab melting point, nws softening kub ncav cuag 550 ~ 750 ℃, zoo tshuaj stability, tsis yooj yim rau hlawv, muaj tej yam zoo heev yam ntxwv xws li corrosion kuj, thiab tau dav siv nyob rau hauv ntau yam teb. .
2 Cov yam ntxwv ntawm iav fiber ntau
Lub melting point ntawm iav fiber ntau yog 680 ℃, lub boiling point yog 1000 ℃, thiab qhov ceev yog 2.4 ~ 2.7g / cm3.Lub zog tensile yog 6.3 txog 6.9 g / d hauv lub xeev tus qauv thiab 5.4 txog 5.8 g / d hauv lub xeev ntub.iav fiber ntau Nws muaj cov khoom siv hluav taws xob zoo thiab yog cov khoom siv hluav taws xob zoo nrog cov rwb thaiv tsev zoo, uas tsim nyog rau kev tsim cov thermal rwb thaiv tsev thiab cov khoom siv hluav taws xob.
3 Cov iav fiber ntau
Cov iav siv hauv kev tsim cov iav fiber ntau txawv ntawm cov iav siv hauv lwm cov khoom iav.Cov iav siv los tsim cov iav fibers muaj cov hauv qab no:
(1)E-iav,tseem hu ua alkali-dawb iav, belongs rau borosilicate iav.Ntawm cov ntaub ntawv tam sim no siv hauv kev tsim cov iav fibers, iav tsis muaj alkali yog siv dav tshaj plaws.Alkali-dawb iav muaj cov rwb thaiv tsev zoo thiab cov khoom siv kho tshuab, thiab feem ntau yog siv los tsim cov iav fiber ntau thiab lub zog iav fiber ntau, tab sis alkali-dawb iav tsis resistant rau inorganic acid corrosion, yog li nws tsis haum rau siv nyob rau hauv acidic ib puag ncig. .Peb muaj e-iavfiberglass rov, e iavfiberglass woven roving,thiab e-iavfiberglass mat.
(2)C-iav, tseem hu ua medium alkali iav.Piv nrog rau cov iav tsis muaj alkali, nws muaj cov tshuaj tiv thaiv zoo dua thiab tsis muaj hluav taws xob thiab cov khoom siv kho tshuab.Ntxiv diboron trichloride rau nruab nrab alkali iav tuaj yeem tsimiav fiber nto lev,uas muaj cov yam ntxwv ntawm corrosion kuj.Boron-dawb nruab nrab-alkali iav fibers yog tsuas yog siv nyob rau hauv zus tau tej cov lim fabrics thiab wrapping fabrics.
(3)High-lub zog iav fiber ntau,Raws li lub npe qhia, muaj zog iav fiber ntau muaj cov yam ntxwv ntawm lub zog siab thiab siab modulus.Nws lub zog tensile fiber ntau yog 2800MPa, uas yog kwv yees li 25% siab dua li cov iav tsis muaj alkali, thiab nws cov elastic modulus yog 86000MPa, uas siab dua li ntawm E-iav fiber ntau.Cov zis ntawm lub zog iav fiber ntau tsis siab, ua ke nrog nws lub zog siab thiab siab modulus, yog li nws feem ntau yog siv rau hauv cov tub rog, aerospace thiab cov cuab yeej ua kis las thiab lwm yam, thiab nws tsis yog siv dav hauv lwm qhov chaw.
(4)AR iav fiber ntau, tseem hu ua alkali-resistant iav fiber, yog ib qho inorganic fiber.Lub alkali-resistant iav fiber ntau muaj alkali tsis kam thiab tuaj yeem tiv taus corrosion ntawm siab alkali tshuaj.Nws muaj qhov tsis tshua muaj siab elastic modulus thiab cuam tshuam tsis kam, tensile lub zog thiab khoov lub zog.Nws kuj muaj cov yam ntxwv ntawm non-combustibility, Frost tsis kam, kub thiab av noo kuj, tawg kuj, impermeability, muaj zog plasticity thiab yooj yim molding.Rib khoom rau iav fiber reinforced qhob.
4 Kev npaj cov iav fibers
Txoj kev tsim khoom ntawmiav fiberfeem ntau yog ua ntej yaj cov ntaub ntawv raw, thiab tom qab ntawd ua kev kho fiber ntau.Yog tias nws yuav tsum tau ua rau hauv cov duab ntawm cov iav fiber ntau lossis fiberglass rods, kev kho fiber ntau tsis tuaj yeem ua ncaj qha.Muaj peb txheej txheem fibrillation rau iav fibers:
Txoj kev kos duab: txoj hauv kev tseem ceeb yog txoj kev kos duab nozzle, ua raws li cov iav pas nrig kos duab thiab cov txheej txheem yaj poob;
Txoj kev centrifugal: nruas centrifugation, kauj ruam centrifugation thiab kab rov tav porcelain disc centrifugation;
Blowing method: tshuab tshuab thiab nozzle tshuab.
Cov txheej txheem saum toj no kuj tseem siv tau ua ke, xws li kos duab- tshuab thiab lwm yam.Post-processing tshwm sim tom qab fiberizing.Tom qab ua tiav ntawm textile iav fibers tau muab faib ua ob theem loj hauv qab no:
(1) Thaum lub sij hawm tsim cov iav fibers, cov iav filaments ua ke ua ntej winding yuav tsum tau sizing, thiab luv fibers yuav tsum tau txau nrog lubricant ua ntej yuav sau thiab drummed nrog qhov.
(2) Kev ua haujlwm ntxiv, raws li qhov xwm txheej ntawm cov iav fiber ntau thiab luv luviav fiber ntau rov muaj cov kauj ruam hauv qab no:
① Luv iav fiber ntau cov kauj ruam:
② Ua cov kauj ruam ntawm iav staple fiber roving:
