Cov iav fiber yog ib qho ntawm cov ntaub ntawv tseem ceeb ntawm fiberglass qab nthab thiab fiberglass suab-absorbing panels. Ntxivcov iav fiberrau gypsum boards feem ntau yog kom ua kom lub zog ntawm cov vaj huam sib luag. Lub zog ntawm fiberglass qab nthab thiab cov vaj huam sib luag uas nqus suab kuj raug cuam tshuam ncaj qha los ntawm qhov zoo ntawm cov iav fibers. Hnub no peb yuav tham txog fiberglass.
Yog dab tsifiberglass:
Cov iav fiber yog cov khoom siv inorganic uas tsis yog hlau uas muaj kev ua tau zoo heev. Muaj ntau hom. Qhov zoo yog kev rwb thaiv tsev zoo, tiv taus cua sov tau zoo, tiv taus xeb tau zoo thiab muaj zog kho tshuab tau zoo.
Cov lus qhia ntawm cov iav fiber:
Tus cim qhia thawj zaug:Tus neeg sawv cev kho qhov chaw siv rau hauv cov txheej txheem kos duab ntawm cov iav fiber. Tus neeg sawv cev kho qhov chaw tseem hu ua tus neeg sawv cev ntub dej, tus neeg sawv cev ntub dej feem ntau yog tus neeg sawv cev sib txuas thiab tus neeg sawv cev ua zaj duab xis, thiab kuj muaj qee cov roj nplua nyeem, cov tshuaj antioxidants, emulsifiers, cov neeg sawv cev antistatic, thiab lwm yam. Cov hom ntxiv lwm yam muaj kev cuam tshuam loj rau cov iav fiber, yog li thaum xaiv cov iav fiber, xaiv cov iav fiber tsim nyog raws li qhov xav tau ntawm cov khoom siv hauv paus thiab cov khoom tiav.
Qhov cim qhia thib ob:lub cheeb ntawm lub monofilament. Yav dhau los nws tau qhia tias qhov ntev ntawm cov iav fiber tseem ceeb tsuas yog cuam tshuam nrog lub zog shear thiab lub cheeb ntawm lub filament. Hauv kev xav, qhov me dua ntawm lub filament, qhov zoo dua cov khoom siv kho tshuab thiab qhov tsos ntawm cov khoom. Tam sim no, lub cheeb ntawm cov iav fiber hauv tsev feem ntau yog 10μm thiab 13μm.
Kev faib tawm ntawmcov iav fiber
Feem ntau, nws tuaj yeem raug faib ua pawg raws li cov khoom siv iav raw, lub cheeb ntawm monofilament, qhov tsos ntawm fiber, txoj kev tsim khoom thiab cov yam ntxwv ntawm fiber.
Raws li cov khoom siv iav raw, nws yog siv rau kev faib tawm ntawm cov iav fibers tas mus li.
Feem ntau nws yog qhov sib txawv los ntawm cov ntsiab lus ntawm cov alkali hlau oxides sib txawv, thiab alkali hlau oxides feem ntau xa mus rau sodium oxide thiab potassium oxide. Hauv cov khoom siv iav raw, nws yog qhia los ntawm soda tshauv, Glauber ntsev, feldspar thiab lwm yam tshuaj. Alkali hlau oxide yog ib qho ntawm cov khoom tseem ceeb ntawm cov iav zoo tib yam, thiab nws lub luag haujlwm tseem ceeb yog txo qhov melting point ntawm iav. Txawm li cas los xij, qhov siab dua cov ntsiab lus ntawm alkali hlau oxides hauv iav, nws cov tshuaj lom neeg ruaj khov, hluav taws xob rwb thaiv tsev thiab lub zog yuav txo qis raws li. Yog li ntawd, rau cov iav fibers nrog kev siv sib txawv, cov khoom iav nrog cov ntsiab lus alkali sib txawv yuav tsum tau siv. Yog li ntawd, cov ntsiab lus alkali ntawm cov khoom iav fiber feem ntau yog siv ua lub cim los sib txawv cov iav fibers txuas ntxiv rau ntau lub hom phiaj. Raws li cov ntsiab lus alkali hauv cov iav muaj pes tsawg leeg, cov fibers txuas ntxiv tuaj yeem faib ua cov hom hauv qab no:
Cov fiber tsis muaj alkali (feem ntau hu ua E iav):Cov ntsiab lus R2O tsawg dua 0.8%, uas yog ib qho khoom aluminoborosilicate. Nws cov tshuaj lom neeg ruaj khov, cov khoom rwb thaiv tsev hluav taws xob, thiab lub zog zoo heev. Feem ntau siv ua cov khoom rwb thaiv tsev hluav taws xob, cov khoom siv txhawb nqa ntawm cov iav fiber reinforced yas thiab cov log tsheb.
Nruab Nrab-alkaliiavfiber:Cov ntsiab lus ntawm R2O yog 11.9% -16.4%. Nws yog ib qho khoom siv sodium calcium silicate. Vim nws muaj cov alkali ntau, nws tsis tuaj yeem siv ua cov khoom siv hluav taws xob rwb thaiv tsev, tab sis nws cov tshuaj lom neeg ruaj khov thiab lub zog tseem zoo. Feem ntau siv ua daim ntaub latex, cov ntaub checkered, cov ntaub lim kua qaub, cov ntaub thaiv qhov rai, thiab lwm yam. Nws kuj tseem siv tau ua cov khoom siv FRP txhawb nqa nrog cov kev cai tsawg dua ntawm cov khoom hluav taws xob thiab lub zog. Cov fiber no pheej yig thiab muaj ntau yam kev siv.
Cov fiber ntau alkali:Cov khoom siv iav uas muaj R2O sib npaug lossis ntau dua 15%. Xws li cov iav fibers rub los ntawm cov iav tiaj tiaj, cov iav fwj tawg, thiab lwm yam ua cov khoom siv raw, koom nrog pawg no. Nws tuaj yeem siv ua cov roj teeb cais, daim ntaub qhwv yeeb nkab thiab daim ntawv lev thiab lwm yam khoom siv tiv thaiv dej thiab noo noo.
Cov iav fiber tshwj xeebxws li cov iav fibers muaj zog siab uas muaj cov ntshiab magnesium-aluminium-silicon ternary, magnesium-aluminium-silicon muaj zog siab thiab siab elastic iav fibers; silicon-aluminium-calcium-magnesium tshuaj tiv thaiv iav fibers; txhuas-muaj fibers; Silica fiber ntau; quartz fiber, thiab lwm yam.
Kev faib tawm los ntawm txoj kab uas hla ntawm monofilament
Cov iav fiber monofilament yog cylindrical, yog li nws cov tuab tuaj yeem qhia tau hauv txoj kab uas hla. Feem ntau, raws li qhov ntau thiab tsawg ntawm txoj kab uas hla, cov iav fibers kos tau muab faib ua ntau hom (tus nqi ntawm txoj kab uas hla yog hauv um):
Cov fiber nyoos:nws lub monofilament txoj kab uas hla feem ntau yog 30um
Cov fiber tseem ceeb:nws lub monofilament txoj kab uas hla yog ntau dua 20um;
Cov fiber nruab nrab:monofilament txoj kab uas hla 10-20um
Cov fiber ntau ntxiv:(tseem hu ua textile fiber) nws lub monofilament txoj kab uas hla yog 3-10um. Cov iav fibers nrog lub monofilament txoj kab uas hla tsawg dua 4um kuj hu ua ultrafine fibers.
Cov kab sib txawv ntawm monofilaments tsis yog tsuas yog muaj cov khoom sib txawv ntawm cov fibers, tab sis kuj cuam tshuam rau cov txheej txheem ntau lawm, cov zis thiab tus nqi ntawm cov fibers. Feem ntau, 5-10um fiber yog siv rau cov khoom siv textile, thiab 10-14um fiber feem ntau yog tsim rauFiberglasskev mus ncig, cov ntaub tsis yog woven,fiberglasstxiavtxoj hluadaim lev, thiab lwm yam.
Kev faib tawm los ntawm cov tsos ntawm fiber
Qhov tsos ntawm cov iav fibers, piv txwv li nws cov duab thiab ntev, nyob ntawm seb nws tsim tawm li cas, nrog rau nws siv. Nws tuaj yeem muab faib ua:
Cov fiber txuas ntxiv (tseem hu ua cov ntaub fiber):Hauv kev xav, cov fiber txuas ntxiv mus tas li yog cov fiber txuas ntxiv mus tas li uas tsis muaj qhov kawg, feem ntau yog rub los ntawm txoj kev bushing. Tom qab ua cov ntaub, nws tuaj yeem ua rau cov xov iav, hlua, ntaub, siv, tsis muaj kev sib ntswg. Roving thiab lwm yam khoom.
Cov fiber ntev ruaj khov:nws qhov ntev tsuas yog txwv, feem ntau 300-500 hli, tab sis qee zaum nws tuaj yeem ntev dua, xws li cov xov ntev uas tsis zoo hauv daim lev. Piv txwv li, paj rwb ntev ua los ntawm txoj kev tshuab pa tsuas yog ob peb puas millimeters ntev tom qab nws raug rhuav tshem ua cov ntaub plaub roving. Muaj lwm yam khoom xws li txoj kev pas nrig roving thiab thawj roving, uas txhua yam ua rau cov ntaub plaub roving lossis lev.
Cov iav ntaub plaub:Nws tseem yog cov iav fiber ntev ruaj khov, thiab nws cov fiber luv dua, feem ntau qis dua 150 hli lossis luv dua. Nws yog fluffy hauv cov duab, zoo ib yam li paj rwb, yog li nws tseem hu ua paj rwb luv luv. Nws yog siv rau kev khaws cia cua sov thiab lub suab nqus. Tsis tas li ntawd, muaj cov fiber txiav, cov fiber khoob, cov iav fiber hmoov thiab cov fiber milled.
Kev faib tawm los ntawm cov khoom fiber
Qhov no yog ib hom iav fiber tshiab uas tau tsim tshiab los ua kom tau raws li qhov xav tau tshwj xeeb ntawm kev siv. Lub fiber nws tus kheej muaj qee yam tshwj xeeb thiab zoo heev. Nws tuaj yeem muab faib ua: iav fiber muaj zog siab; modulus siabiav fiber; iav fiber ntau tiv taus kub; alkali tsis kam iav fiber; acid-resistant iav fiber; iav fiber ntau (hais txog alkali-dawb thiab nruab nrab-alkali iav fiber); optical fiber; qis dielectric tas li iav fiber; conductive fiber, thiab lwm yam.
