Cov iav fibers tuaj yeem muab faib ua cov fibers txuas ntxiv, ruaj khov -ntev fibers, thiab iav ntaub plaub raws li cov duab thiab ntev; Raws li cov iav muaj pes tsawg leeg, lawv tuaj yeem muab faib ua alkali-dawb, tshuaj lom neeg-resistant, siab-alkali, nruab nrab-alkali, siab-lub zog, siab elastic modulus, thiab alkali-resistant (alkali-}resistant) iav fibers.
Cov ntaub ntawv tseem ceeb rau kev tsim cov iav fiber ntau yog: quartz xuab zeb, alumina thiab pyrophyllite, limestone, dolomite, boric acid, dej qab zib tshauv, Glauber's ntsev, fluorite, thiab lwm yam. Cov txheej txheem ntau lawm yog roughly muab faib ua ob pawg: ib qho yog ncaj qha ua fibers los ntawm molten iav; Lwm qhov yog ua ntej ua molten iav rau hauv iav pob los yog rods nrog ib txoj kab uas hla ntawm 20mm, thiab ces kub thiab remelt lawv nyob rau hauv ntau txoj kev los ua zoo heev fibers nrog ib txoj kab uas hla ntawm 3 mus rau 80μm. Infinitely ntev fibers kos los ntawm txhua yam kev kos duab los ntawm platinum alloy daim hlau hu ua nruam iav fibers, feem ntau hu ua ntev fibers. Discontinuous fibers ua los ntawm rollers lossis airflow yog hu ua tsau -ntev iav fibers, feem ntau hu ua luv fibers.
Cov iav fiber ntau tau muab faib ua ntau qib raws li muaj pes tsawg leeg, cov khoom siv, thiab kev siv. Raws li cov txheej txheem qib kev cai (saib cov lus), E- qib iav fiber ntau yog siv ntau dua thiab siv dav hauv cov khoom siv hluav taws xob rwb thaiv tsev; S-qib iav fiber ntau yog fiber ntau tshwj xeeb.
High -qib iav fiber ntau yog tus yam ntxwv ntawm lub zog siab thiab siab modulus. Nws ib leeg fiber ntau tensile zog yog 2800MPa, uas yog hais txog 25% siab dua tensile zog ntawm alkali-dawb iav fiber. Nws elastic modulus yog 86000MPa, uas siab dua E- iav fiber. Cov khoom siv fiberglass uas tsim nrog lawv feem ntau yog siv rau hauv kev lag luam tub rog, qhov chaw, cov khoom siv phom sij, thiab cov khoom ua si.
AR iav fiber kuj hu ua alkali- iav fiber ntau. Alkali-cov iav fiber ntau yog cov khoom siv ntawm cov iav fiber ntau- siv zog (cement) pob zeb (GRC). Nws yog ib lub siab -tus qauv inorganic fiber ntau thiab ib qho zoo tagnrho hloov rau steel thiab asbestos nyob rau hauv uas tsis yog -load- bearing cement Cheebtsam. Cov yam ntxwv ntawm alkali- iav fiber ntau yog cov alkali tsis kam, tuaj yeem tiv taus qhov yaig ntawm siab -alkali tshuaj hauv cov cement, muaj zog tuav lub zog, siab elastic modulus, cuam tshuam tsis kam, tensile zog, thiab flexural zog. Nws tsis yog-flammable, tiv thaiv- khov, thiab muaj zog tiv thaiv kub thiab av noo hloov pauv. Nws muaj zoo heev tawg kuj thiab impermeability zog. Nws muaj cov yam ntxwv ntawm kev tsim muaj zog thiab yooj yim molding. Alkali-resistant iav fiber yog ib qho tshiab ntsuab thiab ib puag ncig tus phooj ywg txhawb cov khoom siv dav siv hauv siab -kev ua tau zoo reinforced (cement) pob zeb.
D iav, tseem hu ua low-dielectric iav, yog siv los tsim tsawg-dielectric iav fibers nrog zoo dielectric zog.
Ntxiv nrog rau cov iav fiber ntau saum toj no, tam sim no muaj cov alkali tshiab - iav fiber ntau dawb uas tsis muaj boron txhua, yog li txo cov pa phem ib puag ncig, tab sis nws cov hluav taws xob rwb thaiv tsev thiab cov khoom siv kho tshuab zoo ib yam li E iav. Kuj tseem muaj hom iav fiber ntau nrog ob lub iav iav, uas tau siv los ua cov iav ntaub plaub. Nws tau hais tias nws kuj muaj peev xwm ua fiberglass - cov khoom siv ntxiv. Tsis tas li ntawd, muaj fluorine-dawb iav fiber ntau, uas yog ib qho kev txhim kho alkali-dawb iav fiber ntau tsim rau kev tiv thaiv ib puag ncig.
Alkali iav los yog dej qab zib txiv qaub iav. Nws yog hom fiberglass uas siv dav tshaj plaws. Alkali iav suav txog kwv yees li 90% ntawm tag nrho cov iav tsim. Nws yog hom khoom siv ntau tshaj plaws thiab siv los ua cov thawv iav xws li jars thiab fwj rau zaub mov thiab dej haus, nrog rau cov iav qhov rais.
Bakingware ua los ntawm tempered soda txiv qaub iav kuj yog ib qho piv txwv ntawm iav. Nws yog pheej yig, muaj peev xwm ua tau, thiab nyuaj heev. A- hom iav fiber ntau tuaj yeem rov ua dua - melted thiab re- softened ntau zaus, ua rau nws yog hom fiber ntau zoo tshaj rau iav rov ua dua tshiab.
AE lossis AR iav sawv cev rau alkali- iav tiv thaiv, uas yog siv tshwj xeeb rau pob zeb. Nws yog cov khoom sib xyaw ua ke ntawm zirconia.
Qhov sib ntxiv ntawm zirconia, ib qho nyuaj, tshav kub- cov ntxhia resistant, ua rau cov fiberglass no haum rau siv hauv pob zeb. AR- iav tiv thaiv pob zeb los ntawm kev tawg los ntawm kev muab lub zog thiab yoog raws. Tsis tas li ntawd, tsis zoo li steel, nws tsis xeb yooj yim.
C- iav los yog chemical iav yog siv los ua qhov zoo nkauj ntawm txheej txheej ntawm laminates rau cov kav dej thiab cov thawv ntim khoom uas khaws dej thiab tshuaj. Vim lub siab concentration ntawm calcium borosilicate siv nyob rau hauv lub iav formulation txheej txheem, nws qhia tau zoo heev tshuaj tiv thaiv nyob rau hauv corrosive ib puag ncig.
C- iav tuav cov tshuaj thiab cov qauv sib npaug hauv ib puag ncig thiab tiv taus cov tshuaj alkaline.
Dielectric iav (D- iav) fibers feem ntau yog siv rau hauv cov khoom siv, cookware, thiab lwm yam. Nws kuj yog ib hom fiberglass zoo tagnrho rau fiber ntau optics vim nws tsis tshua muaj dielectric. Qhov no yog vim muaj cov boron trioxide nyob rau hauv nws muaj pes tsawg leeg.
Cov iav hluav taws xob lossis E- iav ntaub yog cov qauv kev lag luam uas muab 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 qhov kev ua tau zoo li cov fiber ntau tau ua rau nws nyiam nyob rau hauv cov khoom lag luam xws li planters, 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. Nyob rau hauv ua ntej - ntau lawm, cov khoom ntawm E- iav fiber ntau ua kom huv si thiab nyab xeeb ua haujlwm nrog.
Tus qauv iav (S iav) paub txog nws cov khoom siv kho tshuab. Lub npe hom R- iav, S- iav, thiab T- iav tag nrho yog hais txog tib hom iav fiber ntau. Piv nrog E- iav fiber ntau, nws muaj zog tensile thiab modulus ntau dua. 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 fiberglass no yog siab -kev ua tau zoo, nws tsuas yog siv hauv kev lag luam tshwj xeeb thiab muaj kev tsim khoom tsawg. Qhov no kuj txhais tau tias S- iav tuaj yeem kim.
Advantex iav fiber ntau tau siv dav hauv cov roj, roj, thiab kev lag luam mining, nrog rau cov chaw tsim hluav taws xob thiab kev siv dej hiav txwv (kev kho dej phwj tuaj thiab kev kho dej khib nyiab). Nws muab cov khoom siv hluav taws xob thiab hluav taws xob ntawm E- iav nrog cov kua qaub corrosion ntawm E, C, thiab R fiberglass. Nws yog siv nyob rau hauv ib puag ncig uas cov qauv muaj kev cuam tshuam rau corrosion.
