Fiberglass(tseem yog iav fiber) yog ib hom tshiab ntawm cov khoom siv inorganic uas tsis yog hlau nrog kev ua tau zoo dua.
Cov iav fiber siv dav thiab txuas ntxiv nthuav dav. Nyob rau lub sijhawm luv luv, kev loj hlob ntawm plaub qhov kev lag luam loj (cov khoom siv hluav taws xob, tsheb fais fab tshiab, lub zog cua, thiab 5G) yuav coj kev loj hlob txuas ntxiv. Nyob rau lub sijhawm ntev, cov iav fiber thiab nws cov khoom yuav loj hlob sai sai yav tom ntej, qhov kev nkag mus ntawm ntau qhov chaw thov yuav nce ntxiv, thiab qhov chaw ua lag luam kev lag luam yuav dav.
Tam sim no, kuv lub teb chaws tau tsim ib txoj saw hlau ua tiav ntawm cov iav fiber (xov paj qub), cov khoom iav fiber thiab cov khoom siv iav fiber sib xyaw, uas muab faib ua peb thaj chaw: sab saud, nruab nrab thiab qis dua.
Upstream muab cov khoom siv raw tsim nyog rau kev tsim cov iav fiber, suav nrog kev khawb av, lub zog, tshuaj lom neeg thiab lwm yam lag luam.
Kev tsim cov iav fiber nyob hauv nruab nrab ntawm cov saw hlau kev lag luam. Los ntawm kev siv cov khoom siv raw thiab cov txheej txheem tshwj xeeb, iav fiberkev mus ncigthiab cov khoom siv iav fiber thiab cov khoom tsis yog woven raug tsim tawm. Cov khoom no raug ua tiav ntxiv kom dhau los ua cov khoom sib xyaw ua ke.
Cov lag luam hauv qab no suav nrog kev tsim kho vaj tse, kev tiv thaiv ib puag ncig, kev txuag hluav taws xob, lub zog tshiab, thiab kev thauj mus los.
Fiberglass kev lag luam saw:
Fiberglass: Cov Khoom Siv Raw Los Ntawm Sab Nraud
Hauv cov qauv nqi ntawm cov khoom siv iav fiber, cov khoom siv raw ntawm cov iav fiber ntau yog qhov ntau heev, thiab tus nqi suav rau feem ntau.
Cov khoom siv raw ntawm cov iav fiber ntau yog cov khoom siv raw xws li pyrophyllite, kaolin, limestone, thiab lwm yam, uas yog tsim los ntawm kev yaj kub, kos duab hlau, winding, weaving thiab lwm yam txheej txheem, thiab siv rau hauv kev lag luam downstream los ntawm kev tsim cov khoom iav fiber thiab cov khoom siv iav fiber sib xyaw.
Kuv lub teb chaws cov xuab zeb quartz thiab pyrophyllite muaj cov txiaj ntsig zoo ntawm cov peev txheej, thiab qhov kev hloov pauv ntawm tus nqi yog me me, uas muaj kev cuam tshuam me ntsis rau kev lag luam iav fiber tag nrho.
Lub zog fais fab yog qhov thib ob loj tshaj plaws hauv kev tsim cov iav fiber, feem ntau yog cov roj av, platinum thiab rhodium consumables. Hauv cov txheej txheem ntawm kev tsim cov iav fiber, cov chaw tsim khoom siv pas dej ua ke muaj kev vam khom rau lub zog cua sov, xws li roj av, hluav taws xob, thiab cov ntaub ntawv tsim khoom xws li platinum-rhodium alloy bushings.
Nruab Nrab: Cov Khoom Siv Fiberglass
Cov khoom siv iav fiber feem ntau yog muab faib ua cov khoom tsis yog woven thiab cov khoom textile.
Cov khoom tsis-woven yog hais txog cov khoom ua los ntawm cov iav fibers los ntawm cov txheej txheem tsis-woven (mechanical, chemical lossis thermal methods), feem ntau suav nrog cov iav fiber mats (xws licov hlua khid daim levs,
cov lev txuas ntxiv, cov lev uas xuas koob, thiab lwm yam) thiab cov fibers milled.

Raws li cov khoom sib xyaw, cov iav fiber muaj peev xwm muab faib ua cov iav tsis muaj alkali, nruab nrab alkali, siab alkali thiab alkali-resistant iav fiber. Ntawm lawv, cov iav fiber tsis muaj alkali nyob hauv lub ntsiab lus ntawm kev ua lag luam, thiab lub peev xwm tsim khoom ntau dua 95%.
Raws li qhov loj ntawm lub monofilament txoj kab uas hla, nws tuaj yeem muab faib ua peb series: roving, spun roving thiab hluav taws xob yarn. Ntawm lawv, roving feem ntau yog compounded nrog resin los ua iav fiber reinforced yas (iav fiber reinforced yas);tigkev mus ncig tuaj yeem ua rau cov khoom siv iav fiber ntau; cov xov hluav taws xob yog woven rau hauv daim ntaub iav fiber, uas feem ntau yog siv los tsim cov tooj liab clad laminates ua cov khoom siv raw rau cov laug cam luam tawm.
Los ntawm qhov kev xav ntawm qhov sib piv ntawm lub peev xwm tsim khoom, qhov tso zis ntawm kev roving hauv kuv lub tebchaws suav txog li 70% -75%, tab sis nrog kev tshem tawm thiab kev hloov kho ntawm kev tsim khoom roving, qhov sib piv ntawm kev roving maj mam txo qis.
Cov cheeb tsam thov hauv qab
Cov iav fiber tsis yog daim ntawv kawg ntawm cov ntawv thov downstream, tab sis yog siv ua cov khoom nruab nrab thiab cov khoom downstream los tsim cov khoom siv fiber ntau sib xyaw ua ke los txhim kho kev ua tau zoo ntawm cov khoom siv.
Cov dej ntws ntawm kev lag luam iav fiber yog tawg ua ntau thiab muaj feem cuam tshuam nrog kev lag luam macro.
Tam sim no, cov ntaub ntawv siv hauv tsev, kev thauj mus los, kev lag luam thiab lub zog cua yog cov lag luam tseem ceeb ntawm cov iav fiber, thiab plaub lub lag luam suav txog 87% ntawm cov qauv thov iav fiber.
Nyob rau hauv keeb kwm yav dhau los ntawm "ob chav carbon", cov cai txhawb kev hloov kho ntawm cov qauv zog, kev nqis peev ntawm lub zog cua yuav tsum tswj hwm qhov muaj zog siab, kev thov rov qab los ntawm lub zog cua yuav maj mam rov qab los, thiab tus nqi nkag mus ntawm cov tsheb fais fab tshiab tau nce ntxiv tas li, tsav tsheb nce ntxiv ntawm kev siv cov ntaub ntawv iav fiber cuam tshuam, thiab sab kev thov Lub sijhawm nruab nrab thiab ntev kev loj hlob tseem zoo.
Hauv kev lag luam fais fab cua, cov iav fiber feem ntau yog siv rau hauv kev tsim cov hniav fais fab cua thiab cov npog nacelle. Tam sim no Tuam Tshoj tau dhau los ua lub khw muag khoom fais fab cua loj tshaj plaws hauv ntiaj teb.
Kev loj hlob sai ntawm kev lag luam cua ntawm kuv lub teb chaws tau tsav tsheb kev loj hlob sai ntawm qhov kev thov rau cov iav fiber thiab nws cov khoom. Nrog rau kev txhim kho tas mus li ntawm kev lag luam cua yav tom ntej, thiab kev siv ntau cov kab tsim khoom cua, kev siv cov iav fiber muaj kev cia siab dav.
Cov xov paj iav hluav taws xob yog ib hom khoom siv iav fiber uas muaj kev rwb thaiv tsev zoo, uas tuaj yeem ua rau daim ntaub iav fiber, uas yog siv rau kev tsim cov tooj liab clad laminate, lub hauv paus substrate ntawm lub rooj tsavxwm luam tawm (PCB).
Raws li qhov zoo ntawm tus nqi tam sim no, kev txhawb nqa ntxiv rau kev tsim cov chaw tsim khoom ntse, txo cov nqi zog ua haujlwm, thiab txo kev siv hluav taws xob los ntawm kev hloov pauv kev kho txias yog txoj hauv kev tseem ceeb rau kuv lub tebchaws los tswj hwm qhov zoo ntawm tus nqi thiab txhawb nqa qhov kev siv nyiaj.
Raws li txoj kev npaj txhim kho "14th Five-Year" ntawm Tuam Tshoj Glass Fiber Industry Association, kev tsim kho tshiab yog lub zog tseem ceeb los txhawb kev siv cov kev hloov pauv ntawm sab kev muab khoom hauv kev lag luam iav fiber. Tswj hwm kev loj hlob ntau dhau ntawm kev tsim khoom lag luam; coj kev ua lag luam ua tus qhia, ua haujlwm zoo hauv kev tshawb fawb thiab kev txhim kho thiab kev nthuav dav kev ua lag luam ntawm iav fiber thiab cov khoom; tsom mus rau kev txhawb nqa tag nrho kev lag luam kom txhim kho mus rau kev txawj ntse, ntsuab, kev sib txawv thiab kev thoob ntiaj teb, thiab ua tiav kev txhim kho zoo.
