Cov iav fiber muaj cov khoom zoo thiab yog siv dav hauv ntau thaj teb. Nws yog ib qho khoom xyaw tsis yog xim hlau uas tuaj yeem hloov cov hlau. Vim tias nws txoj kev txhim kho zoo, cov tuam txhab fiber ntau tau tsom rau kev tshawb fawb ntawm cov iav fiber ntau.
1 lub ntsiab lus ntawm cov iav fiber ntau
Iav Fiber yog ib hom inorganic cov khoom siv tsis yog xim hlau uas tuaj yeem hloov cov hlau thiab muaj kev ua tau zoo heev. Nws tau npaj los ntawm Kos Duab Molten Germ rau hauv cov fibers los ntawm kev nqis tes ua ntawm sab nraud quab yuam. Nws muaj cov yam ntxwv ntawm lub zog siab, cov modulus siab thiab tsis tshua muaj elongation. Thaum tshav kub kub ua hauj lwm thiab plhaw platform, loj melting taw tes, tsis yooj yim rau hlawv, muaj qee yam zoo heev rau corrosion tsis kam, thiab tau siv dav hauv ntau thaj teb Cov.
2 Cov yam ntxwv ntawm cov iav fiber ntau
Lub ntsiab lus melting ntawm cov iav fiber yog 680 ℃, lub qhov cub npau yog 1000 ℃, thiab lub ntom ntom yog 2.4 ~ 2.7g / cm3. Lub zog tensile yog 6.3 mus rau 6.9 g / d nyob rau hauv tus qauv xeev thiab 5.4 mus rau 5.8 G / d nyob rau lub xeev ntub.Iav Fiber Muaj cov cua sov tsis kam thiab yog cov khoom siv insulating zoo nrog cov khoom rwb thaiv tsev zoo, uas yog qhov tsim nyog rau cov khoom siv hluav taws xob thiab hluav taws kub.
3 COMPOSITION NTAWM IAV Fiber
Lub iav siv nyob rau hauv kev tsim cov iav fibers yog txawv ntawm cov iav siv hauv lwm cov khoom siv iav. Lub iav siv nyob rau hauv kev tsim cov iav fibers muaj cov hauv qab no:
(1)E-iav,Kuj tseem hu ua cov iav Alkali dawb, belongs rau borosilicate iav. Ntawm cov ntaub ntawv tam sim no siv nyob rau hauv kev tsim cov iav fibers, cov iav alkali-dawb yog qhov feem ntau siv. Alkali-dawb iav muaj cov khoom siv rwb thaiv tsev zoo thiab yog siv cov iav siab tsis txaus ntseeg, yog li nws tsis haum rau kev siv hauv cov acidic ib puag ncig Cov. Peb muaj e-iavFiberglass Rovinging, e-iavFiberglass Woven Roving,thiab e-iavFibrrlllass Mat.
(2)Lub khob c-iav, Kuj tseem hu ua nruab nrab alkali iav. Piv nrog cov iav alkali-dawb, nws muaj cov tshuaj tsis kam zoo thiab cov hluav taws xob tsis zoo thiab cov neeg kho tshuab. Ntxiv Diboron trichhloride rau nruab nrab cov iav alkali tuaj yeem tsimIav Fiber Txawv Mat,uas muaj cov yam ntxwv ntawm corrosion tsis kam. Boron-Free Nruab Nrab-Alkali iav cov fibers yog siv ntau lawm hauv kev tsim cov lim lim thiab qhwv cov ntaub.
(3)High-zog khob fiber ntau,Raws li lub npe qhia, High-zog iav fiber ntau muaj cov yam ntxwv ntawm lub zog siab thiab lub siab modulus. Nws lub zog muaj zog tensile yog 2800MPA, uas yog li 25% siab dua li ntawm cov iav alkali yog 86000mpa, uas yog siab tshaj qhov e-iav fiber ntau. Cov zis ntawm lub zog iav siab yog tsis siab, txuas nrog nws cov khoom siv siab thiab cov khoom siv kis las thiab lwm yam khoom siv kis las thiab lwm thaj chaw, thiab nws tsis yog dav siv hauv lwm daim teb.
(4)AR IAV Fiber, tseem hu ua alkali-resistant iav fiber ntau, yog kev sib deev fiber ntau. Lub alkali-resistant iav fiber muaj zoo alkali kuj thiab tuaj yeem tiv thaiv kev corrosion ntawm cov tshuaj Alkali siab. Nws muaj cov modastic heev heev thiab cuam tshuam kuj, tensile lub zog thiab khoov zog. Nws tseem muaj cov yam ntxwv ntawm cov tsis-ua kom tsis pom zoo, ntsuas kub thiab noo noo, condermeabability, muaj zog yas thiab yooj yim moulding. Tav cov khoom rau iav fiber ntau txhawb kev qhob.
4 npaj cov iav fibers
Cov txheej txheem tsim khoom ntawmIav FiberFeem ntau yog thawj zaug melt cov ntaub ntawv raw, thiab tom qab ntawd ua cov kev kho fiber ntau. Yog tias nws yuav tau ua rau cov duab ntawm cov pob zeb fiber ntau lossis cov pas nrig fiberglass, kev kho fiber ntau, tsis tuaj yeem ua ncaj qha. Muaj peb tus txheej txheem fibrillation rau cov iav fibers:
Txoj kev kos duab: lub hom tseem ceeb yog cov filamin kos duab txoj kev, ua raws li cov iav Rod kos duab kos duab thiab cov qauv tso duab kos duab;
Centrifugal Txujcation: Nruas centrifugation, kauj ruam centrifugation thiab kab rov tav plooj (kab rov tav centrifugation;
Tshuab kev: Tshuab txujci hom thiab nozle tshuab txoj kev.
Cov txheej txheem saum toj no kuj tseem siv tau ua ke, xws li kos duab-tshuab thiab lwm yam. Kev ua haujlwm tom qab ua haujlwm tom qab fiber ntau. Kev ua haujlwm tom qab ntawm textile iav fibers tau muab faib ua cov kauj ruam hauv qab no:
(1) Thaum lub sijhawm zus tau los ntawm cov iav cov fibers, cov iav ua ntej winding yuav tsum yog sizing, thiab cov qoob loo luv yuav tsum tau txau nrog cov roj nplua nyeem ua ntej sau thiab nruas nrog qhov.
(2) Ntxiv kev ua, raws li qhov teeb meem ntawm cov iav luv fiber ntau thiab luvIav Fiber Reoving Muaj cov theem hauv qab no:
Eshort Cov kauj ruam ua cov kauj ruam:
Cov kauj ruam ntawm cov kauj ruam ntawm iav Staple fiber Reoving:
