Raws li cov duab thiab qhov ntev, cov iav fiber tuaj yeem muab faib ua cov fiber txuas ntxiv, cov fiber ntev ruaj khov thiab cov iav ntaub plaub; raws li cov iav muaj pes tsawg leeg, nws tuaj yeem muab faib ua cov tsis muaj alkali, tshuaj lom neeg tsis kam, nruab nrab alkali, lub zog siab, siab elastic modulus thiab alkali tsis kam (alkali tsis kam) fiberglass, thiab lwm yam.
Cov khoom siv tseem ceeb rau kev tsim cov iav fiber yog: quartz xuab zeb, alumina thiab pyrophyllite, limestone, dolomite, boric acid, soda tshauv, mirabilite, fluorite, thiab lwm yam. Cov txheej txheem tsim khoom raug faib ua ob pawg: ib qho yog ua cov iav molten ncaj qha rau hauv cov fibers; qhov thib ob yog ua ntej ua cov iav molten rau hauv cov iav pob lossis pas nrig nrog lub cheeb ntawm 20 hli, thiab tom qab ntawd cua sov thiab rov yaj hauv ntau txoj kev los ua cov iav pob lossis pas nrig nrog lub cheeb ntawm 3 txog 3 hli. 80μm cov fibers zoo heev. Cov fibers ntev tsis kawg kos los ntawm txoj kev kos duab ntawm platinum alloy phaj hu ua cov iav fibers txuas ntxiv, feem ntau hu ua cov fibers ntev. Cov fibers tsis txuas ntxiv ua los ntawm cov menyuam lossis cua ntws, hu ua cov iav fibers ntev, feem ntau hu ua cov fibers luv luv.
Cov iav fibers raug muab faib ua ntau qib raws li lawv cov khoom sib xyaw, cov khoom thiab kev siv. Raws li cov kev cai ntawm qib txheem, E-qib iav fiber yog siv dav thiab siv dav hauv cov ntaub ntawv hluav taws xob insulating; S-qib yog cov fiber tshwj xeeb.
Cov iav siv rau hauv kev tsim cov fiberglass txawv ntawm cov iav siv rau hauv lwm cov khoom iav. Feem ntau, cov khoom sib xyaw ua ke ntawm cov iav rau cov fibers uas tau muag yog raws li nram no:
Lub zog siab thiab siab modulus fiberglass
Nws yog tus cwj pwm los ntawm lub zog siab thiab modulus siab. Nws lub zog tensile ib leeg fiber yog 2800MPa, uas yog li 25% siab dua li ntawm alkali-free iav fiber, thiab nws cov elastic modulus yog 86000MPa, uas yog siab dua E-iav fiber. Cov khoom FRP tsim nrog lawv feem ntau yog siv rau hauv kev lag luam tub rog, aerospace, high-speed tsheb ciav hlau, cua fais fab, bulletproof armor thiab cov khoom siv kis las.
AR fiberglass
Kuj hu ua alkali-resistant glass fiber, alkali-resistant glass fiber yog cov khoom siv rau cov iav fiber reinforced (cement) concrete (hu ua GRC), yog cov inorganic fiber zoo, thiab yog ib qho kev hloov zoo rau hlau thiab asbestos hauv cov khoom cement uas tsis muaj load. Cov yam ntxwv ntawm alkali-resistant glass fiber yog alkali zoo, tuaj yeem tiv taus kev yaig ntawm cov alkali siab hauv cement, muaj zog gripping, siab elastic modulus, cuam tshuam tsis kam, tensile thiab khoov zog, tsis kub hnyiab, te tsis kam, kub tsis kam, muaj zog hloov pauv av noo, zoo heev tawg tsis kam thiab impermeability, muaj zog designability, yooj yim molding, thiab lwm yam. Alkali-resistant glass fiber yog ib hom tshiab ntawm ntsuab thiab tus phooj ywg ib puag ncig siv dav hauv cov khoom siv reinforced (cement) concrete.
D iav
Kuj tseem hu ua iav dielectric qis, nws yog siv los tsim cov iav fibers dielectric qis nrog lub zog dielectric zoo.
Ntxiv rau cov khoom siv iav fiber saum toj no, tam sim no muaj cov iav fiber tshiab uas tsis muaj alkali, uas tsis muaj boron kiag li, yog li txo cov pa phem ib puag ncig, tab sis nws cov khoom siv hluav taws xob rwb thaiv tsev thiab cov khoom siv kho tshuab zoo ib yam li cov iav E ib txwm muaj. Tsis tas li ntawd, muaj cov iav fiber nrog ob chav iav sib xyaw, uas tau siv rau hauv kev tsim cov iav wool, thiab nws kuj tau hais tias muaj peev xwm rau kev txhawb nqa fiberglass. Tsis tas li ntawd, muaj cov iav fiber uas tsis muaj fluorine, uas yog cov iav fiber uas tsis muaj alkali zoo dua uas tsim los rau kev tiv thaiv ib puag ncig.

Tsis tas li ntawd, muaj cov iav fiber nrog ob chav iav sib xyaw, uas tau siv rau hauv kev tsim cov iav wool, thiab nws kuj tau hais tias muaj peev xwm rau kev txhawb nqa fiberglass. Tsis tas li ntawd, muaj cov iav fiber uas tsis muaj fluorine, uas yog cov iav fiber uas tsis muaj alkali zoo dua uas tsim los rau kev tiv thaiv ib puag ncig.
Koj tuaj yeem faib fiberglass ua ntau pawg, nyob ntawm cov khoom siv raw siv thiab lawv cov feem.
Nov yog 7 hom fiberglass sib txawv thiab lawv cov ntawv thov hauv cov khoom siv txhua hnub:
Alkali iav (A-iav)
Iav dej qab zib los yog iav txiv qaub ntsuab. Nws yog hom fiberglass uas siv dav. Iav alkali suav txog li 90% ntawm tag nrho cov iav tsim tawm. Nws yog hom feem ntau thiab siv los ua cov thawv iav, xws li cov kaus poom thiab lub raj mis rau khoom noj thiab dej haus, thiab iav qhov rai.
Cov khoom siv ua noj ua haus uas ua los ntawm cov iav tempered soda lime kuj yog ib qho piv txwv zoo meej ntawm cov iav A. Nws pheej yig, ua tau yooj yim, thiab tawv heev. Cov iav A-hom tuaj yeem yaj dua thiab ua kom mos dua ntau zaus thiab yog cov iav fiber zoo tagnrho rau kev siv cov iav rov ua dua tshiab.
Iav tiv taus alkali AE-iav lossis AR-iav
AE lossis AR iav sawv cev rau alkali resistant iav, uas yog siv tshwj xeeb rau cov pob zeb ua vaj tse. Nws yog cov khoom sib xyaw ua ke uas muaj zirconia.
Qhov ntxiv ntawm zirconia, ib qho khoom siv tawv, tiv taus cua sov, ua rau cov fiberglass no tsim nyog rau kev siv hauv cov pob zeb ua vaj tse. AR-iav tiv thaiv kev tawg ntawm cov pob zeb los ntawm kev muab lub zog thiab kev ywj pheej. Tsis tas li ntawd, tsis zoo li hlau, nws tsis xeb yooj yim.
Cov iav tshuaj lom neeg
C-iav lossis iav tshuaj lom neeg siv ua cov ntaub so ntswg rau txheej sab nraud ntawm cov laminates rau cov kav dej thiab cov thawv rau khaws dej thiab tshuaj lom neeg. Vim yog qhov concentration siab ntawm calcium borosilicate siv rau hauv cov txheej txheem tsim iav, nws qhia tau tias muaj kev tiv thaiv tshuaj lom neeg siab tshaj plaws hauv cov chaw corrosive.
C-iav tswj tau cov tshuaj lom neeg thiab cov qauv sib npaug hauv txhua qhov chaw ib puag ncig thiab tiv taus cov tshuaj alkaline.
Dielectric iav
Cov iav dielectric (D-iav) fibers feem ntau siv rau hauv cov khoom siv hauv tsev, cov khoom siv ua noj, thiab lwm yam. Nws kuj yog hom fiberglass zoo tagnrho vim nws qhov dielectric tsis tu ncua qis. Qhov no yog vim muaj boron trioxide hauv nws cov khoom.
Iav hluav taws xob
E-iav lossis E-fiberglass daim ntaub yog tus qauv kev lag luam uas muab kev sib npaug ntawm kev ua tau zoo thiab tus nqi. Nws yog cov khoom sib xyaw ua ke uas sib dua nrog kev siv hauv aerospace, marine thiab industrial ib puag ncig. E-iav 'cov yam ntxwv ua cov fiber reinforcing tau ua rau nws yog qhov nyiam ntawm cov khoom lag luam xws li cov nroj tsuag, surfboards, thiab nkoj.
Cov iav E-iav ua los ntawm cov iav fiber tuaj yeem ua rau txhua yam duab lossis qhov loj me siv cov txheej txheem tsim khoom yooj yim heev. Hauv kev ua ntej tsim khoom, cov yam ntxwv ntawm iav E-iav ua rau nws huv thiab muaj kev nyab xeeb rau kev ua haujlwm nrog.
Cov iav tsim
Cov iav qauv (S iav) yog lub npe hu ua nws cov khoom siv kho tshuab. Cov npe lag luam R-iav, S-iav thiab T-iav txhua tus hais txog tib hom fiberglass. Piv nrog E-iav fiber, nws muaj lub zog tensile thiab modulus siab dua. Cov fiberglass no yog tsim los siv rau hauv kev tiv thaiv thiab kev lag luam aerospace.
Nws kuj tseem siv rau hauv cov ntawv thov ballistic rigid. Vim tias hom iav fiber no muaj kev ua tau zoo, nws tsuas yog siv rau hauv cov lag luam tshwj xeeb nrog cov ntim khoom tsawg. Nws kuj txhais tau tias S-iav tuaj yeem kim.
Advantex fiberglass
Hom fiberglass no siv dav hauv kev lag luam roj, roj av thiab kev khawb av, nrog rau hauv cov chaw tsim hluav taws xob thiab cov ntawv thov hauv dej hiav txwv (cov dej phwj thiab cov dej khib nyiab kho). Nws muab cov khoom siv kho tshuab thiab hluav taws xob ntawm E-iav nrog rau kev tiv thaiv acid corrosion ntawm E, C, R hom iav fibers. Nws yog siv rau hauv cov chaw uas cov qauv yooj yim rau xeb.
