1. Dab tsi yog iav fiber ntau?
iav fiberstau dav siv vim lawv cov nqi-zoo thiab cov khoom zoo, feem ntau hauv kev lag luam composites. Raws li thaum ntxov xyoo pua 18th, cov neeg European pom tau hais tias iav tuaj yeem hloov mus rau hauv fibers rau kev xaws. Lub hleb ntawm Fabkis Emperor Napoleon twb muaj cov ntaub zoo nkauj ua los ntawmfiberglass. Cov iav fibers muaj ob qho tib si filaments thiab luv fibers lossis flocs. Cov iav filaments feem ntau yog siv rau hauv cov ntaub ntawv sib xyaw, cov khoom siv roj hmab, cov khoom siv conveyor, tarpaulins, thiab lwm yam. Cov fibers luv luv feem ntau yog siv hauv cov ntaub ntawv tsis-woven, engineering plastics thiab cov ntaub ntawv sib xyaw.
Cov iav fiber ntau zoo nkauj lub cev thiab cov khoom siv kho tshuab, yooj yim ntawm fabrication, thiab tus nqi qis piv raucarbon fiber ntauua nws cov khoom ntawm kev xaiv rau kev ua haujlwm siab ua haujlwm sib xyaw. Cov iav fibers yog tsim los ntawm oxides ntawm silica. Cov iav fibers muaj cov cuab yeej zoo heev xws li tsis tshua muaj nkig, siab zog, tsis tshua muaj zog thiab lub teeb yuag.
Cov iav fiber reinforced polymers muaj cov chav loj ntawm ntau hom iav fibers, xws li longitudinal fibers, tws fibers, woven mats, thiabchopped strand mats, thiab siv los txhim kho cov khoom siv kho tshuab thiab tribological ntawm cov khoom siv polymer. Cov iav fibers tuaj yeem ua tiav qhov sib piv siab thawj zaug, tab sis brittleness tuaj yeem ua rau cov fibers tawg thaum ua.
1.cov yam ntxwv ntawm iav fiber ntau
Cov yam ntxwv tseem ceeb ntawm iav fiber ntau muaj xws li cov hauv qab no:
Tsis yooj yim rau nqus dej:Cov iav fiber ntau yog cov tshuaj tiv thaiv dej thiab tsis haum rau cov khaub ncaws, vim hws yuav tsis nqus, ua rau cov neeg hnav ntub dej; vim tias cov khoom tsis cuam tshuam los ntawm dej, nws yuav tsis ntsws
Inelasticity:Vim tsis muaj elasticity, cov ntaub muaj me ntsis inherent stretch thiab rov qab. Yog li ntawd, lawv xav tau kev kho saum npoo los tiv thaiv wrinkling.
Siab zog:Fiberglass muaj zog heev, yuav luag zoo li Kevlar. Txawm li cas los xij, thaum cov fibers rub tawm rau ib leeg, lawv tawg thiab ua rau cov ntaub ua rau lub ntsej muag shaggy.
Rwb thaiv tsev:Hauv daim ntawv luv luv, fiberglass yog ib qho zoo heev insulator.
Drapability:Cov fibers drape zoo, ua rau lawv zoo tagnrho rau curtains.
Thaum tshav kub kub Resistance:Cov iav fibers muaj qhov kub thiab txias, tuaj yeem tiv taus qhov kub txog 315 ° C, lawv tsis cuam tshuam los ntawm tshav ntuj, tshuaj dawb, kab mob, pwm, kab los yog alkalis.
Raug mob:Cov iav fibers raug cuam tshuam los ntawm hydrofluoric acid thiab kub phosphoric acid. Txij li cov fiber ntau yog cov khoom siv iav, qee cov iav fiber ntau yuav tsum tau ua tib zoo saib xyuas, xws li cov khoom siv rwb thaiv tsev hauv tsev, vim tias cov fibers kawg yog qhov tsis yooj yim thiab tuaj yeem tho rau ntawm daim tawv nqaij, yog li cov hnab looj tes yuav tsum tau hnav thaum tuav fiberglass.
3. Kev tsim cov txheej txheem ntawm iav fiber ntau
iav fiber ntauyog ib qho uas tsis yog-hlau fiber ntau uas tam sim no tau dav siv los ua cov khoom lag luam. Feem ntau, cov khoom siv raw ntawm iav fiber ntau suav nrog ntau yam khoom siv ntuj tsim thiab tshuaj lom neeg tsim, cov khoom tseem ceeb yog silica xuab zeb, limestone thiab soda tshauv.
Silica xuab zeb ua raws li lub khob qub, thaum soda tshauv thiab limestone pab txo qhov kub thiab txias. Qhov qis coefficient ntawm thermal expansion ua ke nrog tsawg thermal conductivity piv rau asbestos thiab organic fibers ua fiberglass ib tug dimensionally ruaj khov khoom uas dissipates tshav kub sai.
iav fibersyog tsim los ntawm direct melting, uas muaj cov txheej txheem xws li compounding, melting, spinning, txheej, ziab, thiab ntim. Lub batch yog thawj lub xeev ntawm iav manufacturing, nyob rau hauv uas cov khoom kom muaj nuj nqis yog sib tov kom huv si thiab ces cov sib tov yog xa mus rau lub cub tawg rau melting ntawm ib tug kub ntawm 1400 ° C. Qhov kub no txaus los hloov cov xuab zeb thiab lwm cov khoom xyaw rau hauv lub xeev molten; cov iav molten ces ntws mus rau hauv lub refiner thiab kub poob mus rau 1370 ° C.
Thaum lub sij hawm spinning ntawm iav fibers, molten iav ntws tawm los ntawm lub tes tsho nrog lub qhov zoo heev. Lub phaj liner yog rhuab hauv hluav taws xob thiab nws qhov kub thiab txias yog tswj kom muaj viscosity tas li. Lub dav hlau dej tau siv los ua kom txias cov ntaub ntawv thaum nws tawm ntawm lub tes tsho ntawm qhov kub ntawm kwv yees li 1204 ° C.
Lub extruded kwj ntawm molten iav yog mechanically kos rau hauv filaments nrog diameters li ntawm 4 μm mus rau 34 μm. Kev nruj yog muab los ntawm kev siv lub tshuab cua kub ceev thiab cov iav molten yog kos rau hauv filaments. Nyob rau theem kawg, tshuaj coatings ntawm lubricants, binders thiab coupling agents yog siv rau cov filaments. Lubrication pab tiv thaiv cov filaments los ntawm puas thaum lawv tau sau thiab raug mob rau hauv pob. Tom qab sizing, cov fibers yog qhuav nyob rau hauv ib lub qhov cub; Tom qab ntawd cov filaments tau npaj rau kev ua haujlwm ntxiv rau hauv cov fibers tws, rovings lossis yarns.
4.daim ntawv thov ntawm iav fiber
Fiberglass yog cov khoom siv tsis zoo uas tsis hlawv thiab khaws cia txog 25% ntawm nws lub zog pib ntawm 540 ° C. Feem ntau cov tshuaj muaj me ntsis cuam tshuam rau cov iav fibers. Inorganic fiberglass yuav tsis pwm los yog deteriorate. Cov iav fibers raug cuam tshuam los ntawm hydrofluoric acid, kub phosphoric acid thiab muaj zog alkaline tshuaj.
Nws yog cov khoom siv hluav taws xob zoo heev.Fiberglass ntaubmuaj cov khoom xws li tsis muaj noo noo nqus, siab zog, kub tsis kam thiab tsis tshua muaj dielectric tas li, ua rau lawv zoo tagnrho cov khoom siv rau cov ntawv luam tawm Circuit Court boards thiab insulating varnishes.
Qhov siab zog-rau-qhov hnyav piv ntawm fiberglass ua rau nws yog ib qho khoom siv zoo heev rau cov ntawv thov uas xav tau lub zog siab thiab qhov hnyav tsawg. Nyob rau hauv daim ntawv textile, lub zog no tuaj yeem yog unidirectional lossis bidirectional, tso cai rau kev hloov pauv hauv kev tsim thiab nqi rau ntau yam kev siv hauv kev lag luam tsheb, kev tsim kho vaj tse, kev ua kis las, aerospace, marine, electronics, Tsev thiab cua zog.
Lawv kuj tau siv rau hauv kev tsim cov khoom sib xyaw, cov ntawv luam tawm Circuit Board thiab ntau yam khoom siv tshwj xeeb. Lub ntiaj teb cov iav fiber ntau txhua xyoo yog kwv yees li 4.5 lab tons, thiab cov neeg tsim khoom tseem ceeb yog Tuam Tshoj (60% kev lag luam sib koom), Tebchaws Asmeskas thiab European Union.
