Fiberglass yog ib yam khoom siv inorganic uas tsis yog hlau nrog cov khoom zoo heev. Lub npe thawj lus Askiv: Cov iav fiber. Cov khoom xyaw yog silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, thiab lwm yam. Nws siv cov pob iav lossis cov iav pov tseg ua cov khoom siv raw los ntawm kev kub siab yaj, kos hlau, winding, weaving thiab lwm yam txheej txheem. Thaum kawg, ntau yam khoom tau tsim. Lub cheeb ntawm iav fiber monofilament yog los ntawm ob peb microns mus rau ntau dua 20 microns, uas yog sib npaug rau 1/20-1/5 ntawm ib txoj plaub hau. Nws yog tsim los ntawm ntau txhiab tus monofilaments thiab feem ntau yog siv ua cov khoom siv reinforcing hauv cov ntaub ntawv sib xyaw, cov ntaub ntawv hluav taws xob rwb thaiv tsev thiab cov ntaub ntawv thermal rwb thaiv tsev, cov khoom siv hluav taws xob, thiab lwm yam.
Qhov zoo ntawm cov iav fiber yog txawv los ntawm ntau yam khoom yam ntxwv:
Feem ntau cov iav yog suav tias yog ib yam khoom tawv thiab yooj ywm, thiab nws tsis haum rau kev siv ua cov khoom siv hauv tsev. Txawm li cas los xij, yog tias nws raug rub mus rau hauv daim ntaub txhob lo lo ntxhuav, nws lub zog yuav nce ntxiv ntau thiab nws muaj kev ywj pheej. Yog li ntawd, nws tuaj yeem ua cov khoom siv hauv tsev zoo heev tom qab tau muab cov duab nrog cov resin. Cov iav fibers nce ntxiv hauv lub zog raws li lawv txoj kab uas hla txo qis. Raws li cov khoom siv txhawb nqa,iav fibermuaj cov yam ntxwv hauv qab no:
(1) Lub zog tensile siab thiab me me elongation (3%).
(2) Cov coefficient elastic siab thiab rigidity zoo.
(3) Tus nqi ntawm elongation hauv qhov txwv elastic yog loj thiab lub zog tensile yog siab, yog li qhov nqus ntawm lub zog cuam tshuam yog loj.
(4) Nws yog ib qho inorganic fiber, uas tsis yog flammable thiab muaj tshuaj lom neeg zoo.
(5) Kev nqus dej tsawg.
(6) Qhov ruaj khov ntawm qhov ntev thiab kev tiv taus cua sov yog txhua yam zoo.
(7) Pob tshab thiab tuaj yeem kis lub teeb.
Qhov zoo cuam tshuam li cas rau E-iav fiberkev mus ncig?
Peb txhua tus paub tias thaum yuav khoomE-iav fiberkev mus ncig, peb yuav tsum yuav E-iav fiber roving zoo, tab sis koj puas paub tias qhov zoo ntawm E-iav fiber roving cuam tshuam li cas rau E-iav fiber roving?
Qhov tseeb, qhov zoo ntawm E-iav fiber roving muaj qhov cuam tshuam rau E-iav fiber roving. Piv txwv li, lub neej ua haujlwm ntawm E-iav fiber roving muaj feem cuam tshuam nrog qhov zoo ntawm E-iav fiber roving. Tsis tas li ntawd, qhov zoo kuj cuam tshuam rau kev siv E-iav fiber roving kev lag luam.
Thaum peb xaiv yuav cov iav fiber roving uas tsis muaj alkali, peb yuav tsum sim peb qhov zoo tshaj plaws kom tsis txhob yuav cov khoom pheej yig, thiab peb yuav tsum yuav cov iav fiber roving uas tsis muaj alkali raws li qhov zoo ntawm cov iav fiber roving uas tsis muaj alkali. Ua raws li lub tswv yim ntawm kev ua haujlwm, kev tsim kho tshiab, kev ncaj ncees thiab kev pabcuam rau cov neeg siv khoom,CQDJComapantxuas ntxiv txhim kho thiab siv zog rau kev txhim kho, nrog lub hom phiaj ntawm kev tsim cov khoom siv zoo, tsim kom muaj lub tuam txhab ua lag luam iav fiber, 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 yuav koom tes nrog koj thiab koom tes ua ke rau kev txhim kho kev lag luam iav fiber ntawm kuv lub teb chaws.
Yuav ua li cas kom paub qhov txawv ntawm cov iav fiber alkali-free zookev mus ncig?
Tam sim no, kev siv covE-iav fiber rovingyog ntau dua thiab ntau dua, yog li yuav ua li cas kom paub qhov txawv ntawm E-iav fiber roving thaum yuav nws? Cov hauv qab no yog kev taw qhia los ntawm cov chaw tsim khoom siv iav fiber roving alkali. Kuv vam tias cov lus qhia hauv qab no yuav pab tau rau koj.
1. Nws paub los ntawm lub chaw tsim khoom siv iav fiber ntau alkaline tias cov iav fiber ntau alkaline roving zoo dua muaj qhov chaw huv si, cov kab warp thiab weft ntawm daim phiaj yog txawm thiab ncaj, qhov toughness zoo dua, thiab lub mesh yog sib xws. Ntawm qhov tod tes, cov iav fiber ntau alkaline roving tsis zoo muaj cov phiaj tsis sib xws thiab toughness tsis zoo.
2. Cov iav fiber roving uas tsis muaj alkalinrog rau qhov zoo dua yog glossy thiab sib xws hauv xim, thaum lub alkali-free glass fiber roving nrog qhov tsis zoo tsis yog tsuas yog thorny kov, tab sis kuj tsaus thiab turbid hauv xim.
3. Qhov zoo ntawm E-iav fiber roving kuj tuaj yeem txiav txim siab los ntawm kev ncab nws. E-iav fiber roving nrog qhov zoo tsis yooj yim deformed, thiab tuaj yeem rov qab tau los ntawm kev ncab, thaum E-iav fiber roving nrog qhov tsis zoo yog qhov nyuaj rau rov qab los ntawm lawv qhov deformation tom qab raug ncab, uas yuav cuam tshuam rau kev siv ib txwm muaj.
