1. Dab tsi yog cov iav fiber ntau?
Lub khob fiberstau siv dav vim lawv cov nqi-ua tau zoo thiab cov khoom zoo, feem ntau yog nyob rau hauv kev lag luam sib xyaw. Thaum ntxov li xyoo 18th, cov neeg European pom tau tias iav tuaj yeem spun mus rau hauv cov fibers rau weavers. Lub hleb ntawm Fabkis Emperor Napoleon twb tau kho cov ntaub ua kom zoo nkauj ua los ntawmiav yasCov. Cov iav fibers muaj ob qho tib si filaments thiab luv luv fibers lossis flocs. Cov khoom siv iav uas siv tau siv nyob rau hauv cov khoom siv sib xyaw, cov khoom siv roj hmab, cov khoom siv roj hmab, thiab lwm yam.
Iav Fiber ntau lub cev zoo nkauj thiab cov kws kho tshuab, yooj yim ntawm cov fabrication, thiab tus nqi qis piv rauCarbon FiberUa nws cov khoom siv ntawm kev xaiv rau cov ntawv thov siab composite. Cov iav fibers yog tsim los ntawm oxides ntawm silica. Cov iav fibers muaj cov khoom siv neeg kho kom zoo dua xws li muaj qhov loj dua, lub zog siab, lub zog txhav thiab tawv.
Cov fiber fiber ntau txhawb cov polymers muaj cov chav kawm sib txawv ntawm cov pob sib txawv, xws li ntev ntev, tws mats, thiabtws mats, thiab siv los txhim kho cov neeg kho tshuab thiab cov kev siv zog ntawm cov khoom sib xyaw polymer. Cov iav fibers tuaj yeem ua tiav qhov kev ua tiav zoo siab, tab sis brittleness tuaj yeem ua rau cov fibers tawg thaum ua.
1.Qhov yam ntxwv ntawm cov iav fiber ntau
Cov yam ntxwv tseem ceeb ntawm cov iav fiber muaj xws li cov hauv qab no:
Tsis yooj yim rau nqus dej:Cov iav fiber ntau yog cov tshuaj pleev cov dej ntws thiab tsis haum rau cov khaub ncaws, vim tias hws yuav tsis nqus, ua rau cov ntoo xav ntub; Vim tias cov khoom siv tsis cuam tshuam los ntawm dej, nws yuav tsis ntsws
Intelasticity:Vim yog cov tsis muaj elasticity, cov ntaub muaj me ntsis xam ncab thiab rov qab los. Yog li ntawd, lawv xav tau txoj kev kho deg kom tiv thaiv wrinkling.
Lub zog siab:Fiberglass yog qhov muaj zog heev, yuav luag muaj zog li kev muag muag. Txawm li cas los xij, thaum cov fibers rub tawm tsam ib leeg, lawv tawg thiab ua rau cov ntaub los noj ntawm cov tsos mob shaggy.
Rwb thaiv tsev:Hauv cov ntawv luv luv, fiberglass yog ib qho zoo heev insulator.
Drapability:Cov fibers drape zoo, ua rau lawv zoo tagnrho rau cov ntaub.
Thaum tshav kub kub tiv:Cov iav fibers muaj cov kub kub kuj, tuaj yeem tiv thaiv kub txog li 315 ° C, tshuaj dawb, pwm, kab lossis alkalis.
Raug cuam tshuam tau:Iav Fibers cuam tshuam los ntawm hydrofluoric acid thiab kub phosphoric acid. Txij li thaum muaj fiber ntau yog cov khoom lag luam iav, qee cov hnab ntim nqaij nyoos yuav tsum daws tau cov tawv nqaij, vim tias cov hnab looj tes hauv tsev, yog li cov hnab looj tes yog cov hnab looj tes, yog li cov hnab looj tes, yog li cov hnab looj tes, yog li cov hnab looj tes kom zoo li cov ntaub qhwv tsev neeg, yog li cov hnab looj tes ua haujlwm, yog li cov hnab looj tes yog cov hnab looj tes kom khov, yog li cov hnab looj tes yog li cov hnab looj tes khov kho
3. Kev tsim qauv txheej txheem ntawm cov iav fiber
Iav Fiberyog ib qho tsis yog xim hlau fiber uas tam sim no siv tau ua cov khoom siv muaj. Feem ntau, cov ntaub ntawv raw ntawm cov iav fiber suav nrog ntau yam ntuj thiab cov txiv neej ua yeeb yam yog silica xuab zeb, limestone thiab dej qab.
Silica xuab zeb ua raws li lub khob yav tas los, thaum dej qab zib tshauv thiab limestone pab txo qis melting kub. Qhov qis coefficient ntawm thermal exporsion ua ke nrog qis thermal conductivity piv rau asbestos thiab organic fiberential steable cov ntaub ntawv uas cuam tshuam nrog tshav kub sai sai.
Lub khob fibersYog tsim los ntawm kev coj ncaj qha melting, uas cuam tshuam nrog cov txheej txheem xws li compounding, melting, kiv, qhuav, thiab ntim. Lub Batch yog thawj lub xeev ntawm iav tsim tawm, nyob rau hauv uas cov khoom siv tau muab xyaw ua ke rau melting ntawm qhov kub ntawm 1400 ° C. Qhov kub no txaus kom hloov cov xuab zeb thiab lwm yam khoom xyaw rau hauv lub xeev molten; Lub iav molten ces ntws mus rau hauv lub tsev kho kom sov thiab ntsuas kub poob rau 1370 ° C.
Thaum lub sijhawm tig ntawm cov iav fibers, molten iav ntws tawm ntawm lub tes tsho nrog lub qhov zoo heev. Lub liner phaj yog rhuab hluav taws xob thiab nws qhov kub yog tswj kom tswj tau viscosity tas li. Lub dav hlau dej tau siv rau txias cov ntsiab lus thaum nws tawm ntawm lub tes tsho ntawm qhov kub ntawm kwv yees li ntawm 1204 ° C.
Cov khoom siv hluav taws xob ntawm cov iav me me yog cov txheej txheem rau hauv cov filaments nrog diameters xws li 4 μm rau 34 μm. Kev ntxhov siab yog muab siv lub tshuab cua kub ceev thiab iav molten yog kos rau hauv cov filaments. Nyob rau hauv cov theem kawg, tshuaj lom cov co coricants, binders thiab coupling cov neeg sawv cev tau thov rau cov filaments. Lubrication cov filaments los ntawm kev ua txhaum raws li lawv tau sau thiab mob rau hauv pob khoom. Tom qab sizing, cov fibers yog qhuav hauv qhov cub; Cov filaments yog tom qab npaj rau kev ua ntxiv mus rau hauv cov tws fibers, rovings lossis yarns.
4.Daim ntawv thov ntawm cov iav fiber ntau
Iav yas yog cov khoom siv inorganic uas tsis hlawv thiab khaws cia li 25% ntawm nws lub zog thawj ntawm 540 ° C. Feem ntau cov tshuaj muaj cov nyhuv me me ntawm cov iav fibers. Inorganic fiberglass yuav tsis pwm lossis tsis zoo. Cov iav fibers cuam tshuam los ntawm hydrofluoric acid, kub phosphoric acid thiab cov tshuaj tsw qab.
Nws yog ib qho khoom siv hluav taws xob zoo heev.Fiberglass FabricsMuaj cov khoom lag luam xws li cov dej khov noo noo, lub zog muaj zog, tshav kub ua kom muaj zog, ua rau lawv txhawb nqa hluav taws xob thiab insulating varnishes.
Lub zog muaj zog-rau-qhov hnyav piv ntawm fiberglass ua rau nws muaj cov khoom siv tau zoo rau kev siv lub zog siab thiab qhov hnyav tsawg. Nyob rau hauv daim ntawv nyeem, lub zog no tuaj yeem tsis sib xws lossis kev siv nyiaj hauv kev tsim qauv hauv kev tsim kho tsheb, kev ua kis las, kev ntaus pob ncaws pob, lub tsev thiab cua lub zog.
Lawv kuj tau siv nyob rau hauv kev tsim cov txheej txheem teeb tsa cov txheej txheem, luam tawm cov laug cam thiab ntau yam khoom tshwj xeeb-hom phiaj. Lub ntiaj teb cov iav fiber ntau ntau lawm yog kwv yees li 4.5 lab tons, thiab cov neeg tsim khoom tseem ceeb yog Tuam Tshoj (60% kev lag luam sib koom ua lag luam), Asmeskas thiab European Union.
