Raws li cov duab thiab ntev, iav fiber ntau tuaj yeem muab faib ua fiber ntau txuas ntxiv, ruaj khov-ntev fiber ntau thiab iav ntaub plaub;Raws li cov iav muaj pes tsawg leeg, nws tuaj yeem muab faib ua alkali-dawb, tshuaj tiv thaiv, nruab nrab alkali, siab zog, siab elastic modulus thiab alkali tsis kam (alkali resistance) fiberglass, thiab lwm yam.
Cov ntaub ntawv tseem ceeb rau iav fiber ntau yog: quartz xuab zeb, alumina thiab pyrophyllite, limestone, dolomite, boric acid, dej qab zib tshauv, mirabilite, fluorite, thiab lwm yam. Cov txheej txheem ntau lawm yog roughly muab faib ua ob pawg: ib qho ncaj qha ua molten iav. nyob rau hauv fibers;Lwm qhov yog ua ntej ua cov iav molten rau hauv cov iav pob los yog cov pas nrig nrog txoj kab uas hla ntawm 20 hli, thiab tom qab ntawd kub thiab tshem tawm ntau txoj hauv kev los ua iav pob los yog rods nrog txoj kab uas hla ntawm 3 mus rau 3 hli.80μm fiber ntau zoo.Cov fibers ntev infinitely kos los ntawm cov khoom siv kos duab ntawm platinum alloy daim hlau hu ua cov iav txuas ntxiv, feem ntau hu ua cov fibers ntev.Discontinuous fibers ua los ntawm rollers los yog cua ntws, hu ua taag-ntev iav fibers, feem ntau hu ua luv fibers
Cov iav fibers tau muab faib ua ntau qib raws li lawv qhov muaj pes tsawg leeg, cov khoom thiab kev siv.Raws li cov kev cai ntawm tus qauv qib, E-qib iav fiber ntau yog dav siv thiab dav siv hauv cov khoom siv hluav taws xob insulating;S-qib yog fiber ntau tshwj xeeb.
Cov iav siv hauv kev tsim cov fiberglass txawv ntawm cov iav siv hauv lwm cov khoom iav.Feem ntau, cov iav compositions rau fibers uas tau coj mus muag yog raws li nram no:
Siab zog thiab siab modulus fiberglass
Nws yog tus cwj pwm los ntawm lub zog siab thiab siab modulus.Nws ib leeg fiber ntau tensile zog yog 2800MPa, uas yog hais txog 25% siab dua li ntawm alkali-dawb iav fiber ntau, thiab nws elastic modulus yog 86000MPa, uas yog siab tshaj E-iav fiber.FRP cov khoom tsim nrog lawv feem ntau yog siv hauv kev lag luam tub rog, aerospace, high-speed rail, cua zog, mos txwv armor thiab cov khoom ua si.
AR fiberglass
Kuj tseem hu ua alkali-resistant iav fiber ntau, alkali-resistant iav fiber ntau yog ib qho khoom siv ntxiv rau iav fiber ntau reinforced (cement) pob zeb (hu ua GRC), cov txheej txheem siab inorganic fiber, thiab ib qho zoo tagnrho hloov rau hlau thiab asbestos nyob rau hauv tsis - load-bearing cement Cheebtsam.Cov yam ntxwv ntawm alkali-resistant iav fiber ntau yog zoo alkali tsis kam, tuaj yeem tiv taus qhov yaig ntawm siab alkali tshuaj hauv cov cement, muaj zog tuav quab yuam, siab elastic modulus, cuam tshuam tsis kam, tensile thiab khoov lub zog, tsis-flammable, Frost-resistant, kub. -Resistant, muaj zog humidity hloov muaj peev xwm, zoo heev tawg kuj thiab impermeability, muaj zog designability, yooj yim molding, thiab lwm yam., alkali-resistant iav fiber ntau yog ib yam tshiab ntawm ntsuab thiab environmentally friendly reinforcement lug siv nyob rau hauv high-kev ua tau zoo reinforced (cement) pob zeb khoom. .
D iav
Kuj hu ua low dielectric iav, nws yog siv los tsim cov iav tsis muaj dielectric nrog zoo dielectric zog.
Ntxiv rau cov iav fiber ntau saum toj no, cov iav fiber ntau tsis muaj alkali tshiab tam sim no muaj, uas yog tsis muaj boron kiag li, yog li txo cov pa phem ib puag ncig, tab sis nws cov hluav taws xob insulating zog thiab cov khoom siv kho tshuab zoo ib yam li E iav.Tsis tas li ntawd, muaj cov iav fiber ntau nrog ob chav iav muaj pes tsawg leeg, uas tau siv los tsim cov iav ntaub plaub, thiab nws kuj tau hais tias muaj peev xwm ua kom muaj zog fiberglass.Tsis tas li ntawd, muaj fluorine-dawb iav fiber ntau, uas yog kev txhim kho alkali-dawb iav fiber ntau tsim rau kev tiv thaiv ib puag ncig.

Koj tuaj yeem faib cov fiberglass rau hauv ntau pawg, nyob ntawm cov khoom siv raw thiab lawv cov proportions.
Nov yog 7 ntau hom fiberglass thiab lawv cov ntawv thov hauv cov khoom siv niaj hnub:
Alkali iav (A-iav)
Soda iav los yog dej qab zib lime iav.Nws yog hom fiberglass dav siv.Alkali iav suav txog li 90% ntawm tag nrho cov iav tsim.Nws yog hom ntau tshaj plaws thiab siv los ua cov thawv iav, xws li cov kaus poom thiab lub raj mis rau zaub mov thiab dej haus, thiab lub qhov rais iav.
Cov tais ci ua los ntawm tempered soda txiv qaub iav kuj yog ib qho piv txwv zoo meej ntawm A iav.Nws yog pheej yig, muaj peev xwm ua tau, thiab nyuaj heev.A-hom iav fibers tuaj yeem rov ua dua thiab rov ua dua ntau zaus thiab yog cov iav fiber ntau zoo tagnrho rau iav rov ua dua tshiab.
Alkali-resistant iav AE-iav lossis AR-iav
AE lossis AR iav stands rau alkali resistant iav, uas yog tshwj xeeb yog siv rau pob zeb.Nws yog cov khoom siv sib xyaw ua ke ntawm zirconia.
Qhov sib ntxiv ntawm zirconia, ib qho nyuaj, kub-resistant ntxhia, ua rau cov fiberglass no haum rau siv hauv pob zeb.AR-iav tiv thaiv pob zeb tawg los ntawm kev muab lub zog thiab yoog raws.Tsis tas li ntawd, tsis zoo li steel, nws tsis xeb yooj yim.
Tshuaj iav
C-iav los yog chemical iav yog siv los ua cov ntaub so ntswg rau txheej txheej ntawm laminates rau cov kav dej thiab cov thawv ntim rau khaws dej thiab tshuaj.Vim lub siab concentration ntawm calcium borosilicate siv nyob rau hauv lub iav formulation txheej txheem, nws exhibits siab tshaj tshuaj tiv thaiv nyob rau hauv corrosive ib puag ncig.
C-iav tswj cov tshuaj thiab cov qauv sib npaug hauv ib puag ncig thiab muaj kev tiv thaiv zoo rau cov tshuaj alkaline.
Dielectric iav
Dielectric iav (D-iav) fibers feem ntau siv rau hauv cov khoom siv, cookware, thiab lwm yam.Nws kuj yog ib hom zoo tshaj plaws ntawm fiberglass vim nws tsis tshua muaj dielectric tsis tu ncua.Qhov no yog vim muaj cov boron trioxide nyob rau hauv nws muaj pes tsawg leeg.
Electronic iav
E-iav lossis E-fiberglass daim ntaub yog cov qauv kev lag luam uas muaj qhov sib npaug ntawm kev ua tau zoo thiab tus nqi.Nws yog ib qho khoom siv sib xyaw ua ke nrog kev siv hauv aerospace, marine thiab kev lag luam ib puag ncig.E-iav 'cov khoom raws li kev txhawb nqa fiber ntau tau ua rau nws nyiam ntawm cov khoom lag luam xws li cog ntoo, surfboards, thiab nkoj.
E-iav hauv cov iav ntaub plaub tuaj yeem ua rau txhua yam duab lossis loj siv cov txheej txheem tsim khoom yooj yim heev.Hauv kev tsim khoom ua ntej, cov khoom ntawm E-iav fiber ntau ua kom huv thiab nyab xeeb ua haujlwm nrog.
Tus qauv iav
Tus qauv iav (S iav) paub txog nws cov khoom siv kho tshuab.Cov npe lag luam R-iav, S-iav thiab T-iav tag nrho yog hais txog tib hom fiberglass.Piv nrog E-iav fiber ntau, nws muaj zog tensile ntau dua thiab modulus.Qhov fiberglass no yog tsim los siv rau hauv kev tiv thaiv thiab kev lag luam aerospace.
Nws kuj tseem siv tau rau hauv daim ntawv thov kev siv phom ballistic.Vim tias hom iav fiber ntau no yog qhov ua tau zoo, nws tsuas yog siv hauv kev lag luam tshwj xeeb nrog cov khoom ntim tsawg.Nws kuj txhais tau tias S-iav tuaj yeem kim.
Advantex fiberglass
Hom fiberglass no yog siv dav hauv cov roj, roj thiab kev lag luam mining, nrog rau hauv cov chaw tsim hluav taws xob thiab kev siv dej hiav txwv (kev kho dej phwj thiab dej khib nyiab).Nws muab cov khoom siv hluav taws xob thiab hluav taws xob ntawm E-iav nrog cov kua qaub tiv thaiv ntawm E, C, R hom iav fibers.Nws yog siv nyob rau hauv ib puag ncig uas cov qauv muaj kev cuam tshuam rau corrosion.
