Fiberglass yog ib yam khoom uas tsis yog-metallic nrog cov khoom zoo heev. English original name: iav fiber. Cov khoom xyaw yog silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, thiab lwm yam. Nws siv cov khoom iav los yog cov iav khib nyiab ua raw khoom los ntawm kub melting, hlau kos duab, winding, weaving thiab lwm yam txheej txheem. Thaum kawg, ntau yam khoom raug tsim. Qhov txoj kab uas hla ntawm iav fiber ntau monofilament yog los ntawm ob peb microns mus rau ntau tshaj 20 microns, uas yog sib npaug rau 1/20-1/5 ntawm cov plaub hau. Nws yog tsim los ntawm ntau txhiab tus monofilaments thiab feem ntau yog siv los ua cov khoom siv hauv cov khoom sib xyaw, cov khoom siv hluav taws xob insulating thiab cov ntaub ntawv thermal rwb thaiv tsev, cov khoom siv hluav taws xob, thiab lwm yam.
Qhov zoo ntawm iav fiber ntau yog txawv los ntawm ntau yam khoom yam ntxwv:
iav feem ntau suav hais tias yog ib qho khoom siv tawv thiab tsis muaj zog, thiab nws tsis haum rau siv los ua cov khoom siv. Txawm li cas los xij, yog tias nws tau kos rau hauv cov ntaub lo lo ntxhuav, nws lub zog yuav ua tau zoo heev thiab nws muaj qhov yoog raws. Yog li ntawd, thaum kawg nws tuaj yeem dhau los ua cov khoom siv zoo heev tom qab tau muab cov duab nrog cov resin. Cov iav fibers nce zog thaum lawv txoj kab uas hla txo. Raws li cov khoom siv reinforcing,iav fibermuaj cov yam ntxwv hauv qab no:
(1) Lub zog tensile siab thiab me elongation (3%).
(2) High elastic coefficient thiab zoo rigidity.
(3) Tus nqi ntawm elongation nyob rau hauv qhov txwv elastic yog loj thiab lub zog tensile siab, yog li qhov nqus ntawm lub zog cuam tshuam loj.
(4) Nws yog ib qho inorganic fiber, uas tsis yog-flammable thiab muaj tshuaj tiv thaiv zoo.
(5) Kev nqus dej tsawg.
(6) Qhov seem stability thiab kub tsis kam yog txhua yam zoo.
(7) Pob tshab thiab muaj peev xwm kis tau lub teeb.
Qhov zoo li cas cuam tshuam rau E-iav fiber ntaurov?
Peb txhua tus paub tias thaum yuav khoomE-iav fiber ntaurov, peb yuav tsum yuav E-iav fiber ntau roving ntawm qhov zoo, tab sis koj puas paub tias qhov zoo ntawm E-iav fiber ntau roving cuam tshuam li cas E-iav fiber ntau roving?
Qhov tseeb, qhov zoo ntawm E-iav fiber ntau roving muaj kev cuam tshuam rau E-iav fiber ntau roving. Piv txwv li, kev pab cuam lub neej ntawm E-iav fiber ntau roving yog ze ze rau qhov zoo ntawm E-iav fiber ntau roving. Tsis tas li ntawd, qhov zoo kuj cuam tshuam rau kev siv E-iav fiber ntau roving kev lag luam.
Thaum peb xaiv yuav alkali-dawb iav fiber ntau roving, peb yuav tsum sim peb qhov zoo tshaj plaws kom tsis txhob yuav cov khoom pheej yig, thiab peb yuav tsum yuav alkali-dawb iav fiber ntau roving raws li qhov zoo ntawm alkali-dawb iav fiber ntau roving. Nyob rau hauv txoj kab nrog lub tswv yim ntawm kev tshaj lij, kev tsim kho tshiab, kev ncaj ncees thiab tus cwj pwm ntawm cov neeg siv khoom,CQDJKompajtxuas ntxiv txhim kho thiab siv zog rau txoj kev loj hlob, nrog rau lub hom phiaj ntawm kev tsim cov cuab yeej zoo, tsim cov iav fiber ntau lub lag luam, thiab koom tes nrog cov neeg ua haujlwm hauv tsev thiab txawv teb chaws los tsim kom muaj tag kis zoo dua. Peb tos ntsoov ua tsaug rau kev koom tes nrog koj thiab koom tes nrog kev tsim kho ntawm kuv lub teb chaws cov khoom siv iav fiber ntau.
Yuav ua li cas paub qhov txawv ntawm qhov zoo ntawm alkali-dawb iav fiber ntaurov?
Tam sim no, kev siv ntawmE-iav fiber ntau rov qabyog ntau thiab ntau, yog li yuav ua li cas paub qhov txawv ntawm E-iav fiber ntau roving thaum yuav nws? Cov hauv qab no yog kev taw qhia los ntawm alkali-dawb iav fiber roving chaw tsim tshuaj paus. Kuv vam tias cov lus qhia hauv qab no yuav pab tau koj.
1. Nws yog lub npe hu los ntawm alkali-dawb iav fiber roving chaw tsim tshuaj paus uas alkali-dawb iav fiber roving nrog zoo zoo muaj ib tug huv si nto, warp thiab weft kab ntawm daim phiaj yog txawm thiab ncaj, lub toughness yog zoo dua, thiab cov mesh kuj zoo ib yam. Ntawm qhov tod tes, alkali-dawb iav fiber ntau rov qab nrog cov khoom tsis zoo muaj cov kab sib npaug thiab tsis muaj zog.
2. Cov iav fiber ntau tsis muaj alkali rovingnrog zoo zoo yog glossy thiab uniform nyob rau hauv cov xim, thaum lub alkali-dawb iav fiber rov qab nrog cov neeg pluag zoo tsis yog tsuas yog pos rau kov, tab sis kuj tsaus thiab turbid xim.
3.Qhov zoo ntawm E-iav fiber ntau rov tuaj yeem raug txiav txim los ntawm kev ncab nws. E-iav fiber ntau roving nrog cov khoom zoo tsis yooj yim deformed, thiab tuaj yeem rov qab los ntawm kev ncab, thaum E-iav fiber ntau roving nrog cov khoom tsis zoo yog qhov nyuaj rau rov qab los ntawm lawv cov deformation tom qab ncab, uas yuav cuam tshuam rau kev siv ib txwm.
Luv luv piav qhia txog daim ntawv thov teb ntawm alkali-dawb iav fiber ntaurov
Vim yog cov kev cai tshwj xeeb rau cov ntaub ntawv hauv aerospace, tub rog thiab lwm yam kev lag luam, kev siv E-iav fiber ntau roving yog ntau dua, vim E-iav fiber ntau roving muaj cov yam ntxwv ntawm lub teeb yuag, siab zog, zoo cuam tshuam thiab nplaim hluav taws.
Qhov tsis muaj alkaliiav fiber roving chaw tsim tshuaj paushais tias cov iav tsis muaj alkali-dawb fiber ntau roving muaj qhov zoo ntawm qhov zoo thiab kev ua haujlwm zoo. Piv nrog rau cov hlau, pob zeb thiab lwm yam ntaub ntawv, nws muaj cov yam ntxwv ntawm lub teeb yuag thiab corrosion kuj, uas ua rau alkali-dawb iav fiber ntau rov qab. roving tau dhau los ua cov khoom siv zoo tshaj plaws rau kev tsim vaj tse xws li txuas hniav, docks, txoj kev loj pavements, trestle choj, cov vaj tse hauv dej, thiab cov kav dej.
Daim ntawv thov ntawmE-iav fiber ntau rov qab nyob rau hauv hluav taws xob thiab hluav taws xob teb mas siv nws cov hluav taws xob rwb thaiv tsev, corrosion kuj thiab lwm yam ntxwv. Cov ntawv thov ntawm E-iav fiber ntau roving hauv kev lag luam hluav taws xob thiab hluav taws xob feem ntau yog hluav taws xob hloov lub thawv, hluav taws xob thaiv lub thawv, ntsuas vaj huam sib luag npog, insulators, insulating cov cuab yeej, lub cev muaj zog npog npog, thiab lwm yam. brackets, thiab lwm yam.
