Fiberglass yog ib hom inorganic non-metallic khoom uas muaj kev ua tau zoo heev.Nws muaj ntau yam zoo, xws li rwb thaiv tsev zoo, muaj zog tshav kub tsis kam, zoo corrosion kuj thiab siab mechanical zog, tab sis nws qhov tsis zoo yog nkig thiab hnav tsis zoo.Nws yog tsim los ntawm pyrophyllite, quartz xuab zeb, limestone, dolomite, boehmite thiab boehmite los ntawm kub-kub melting, hlau kos duab, xov paj winding, ntaub weaving thiab lwm yam txheej txheem.Txoj kab uas hla ntawm nws cov monofilament yog ob peb microns mus rau ntau tshaj 20 microns, sib npaug rau 1/20-1/5 ntawm cov plaub hau.Txhua pob ntawm fiber ntau precursor yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv ntxiv hauv cov ntaub ntawv sib xyaw, cov khoom siv hluav taws xob rwb thaiv tsev, cov ntaub ntawv thermal rwb thaiv tsev, Circuit Court boards thiab lwm yam kev lag luam hauv lub tebchaws.
Thaum Lub Kaum Hli 27, 2017, cov npe ntawm cov kab mob carcinogens luam tawm los ntawm International Agency for Research on Cancer ntawm Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv tau sau ua ntej rau kev siv.Fibers rau lub hom phiaj tshwj xeeb, xws li E iav thiab "475" iav fiber ntau, tau suav nrog hauv daim ntawv teev npe ntawm Qeb 2B carcinogens, thiab cov iav fiber ntau txuas ntxiv tau suav nrog hauv cov npe ntawm Qib 3 carcinogens.
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 iav muaj pes tsawg leeg, nws tuaj yeem muab faib ua alkali dawb, tshuaj tiv thaiv, siab alkali, nruab nrab alkali, siab 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, mirabilite, fluorite, thiab lwm yam. Cov txheej txheem ntau lawm tuaj yeem faib ua ob pawg: ib qho ncaj qha ua. molten iav rau hauv fibers;Ib qho yog ua kom cov iav molten rau hauv lub khob iav los yog pas nrig nrog txoj kab uas hla ntawm 20 hli, thiab tom qab ntawd kub thiab rov ua kom nws nyob rau hauv ntau txoj kev los ua rau hauv lub khob iav los yog pas nrig nrog txoj kab uas hla ntawm 3-80 μ M ntawm fibers zoo heev. .Lub infinitely ntev fiber ntau kos los ntawm mechanical drawing method los ntawm platinum alloy phaj yog hu ua nruam iav fiber, uas feem ntau hu ua ntev fiber.Cov fiber ntau discontinuous ua los ntawm cov menyuam los yog cua ntws yog hu ua ntev iav fiber ntau, los yog luv fiber ntau.
Cov iav fiber ntau tuaj yeem muab faib ua qib sib txawv raws li nws muaj pes tsawg leeg, xwm thiab siv.Raws li tus qauv, Class E iav fiber ntau yog cov khoom siv hluav taws xob insulating siv dav tshaj plaws;Class S yog fiber ntau tshwj xeeb.
Cov ntaub ntawv qhia tau hais tias qhov concentration ntawm Tuam Tshoj txoj kev lag luam iav fiber ntau yog qhov siab tag nrho, nrog Jushi accounting rau 34%, ua raws li Taishan iav Fiber thiab Chongqing International accounting rau 17% feem.Shandong Fiberglass, Sichuan Weibo, Jiangsu Changhai, Chongqing Sanlei, Henan Guangyuan thiab Xingtai Jinniu suav rau ib feem me me, raws li 9%, 4%, 3%, 2%, 2% thiab 1%.
Muaj ob txoj kev tsim khoom ntawm iav fiber ntau: ob zaug ua cov kab kos duab hluav taws xob thiab ib zaug ua lub tshuab hluav taws xob xaim hluav taws xob.
Lub crucible hlau daim duab txheej txheem muaj ntau txheej txheem.Ua ntej, cov khoom siv iav yog melted rau hauv cov khob iav ntawm qhov kub thiab txias, tom qab ntawd cov iav pob tau yaj dua, thiab cov khoom siv hluav taws xob kub ceev yog ua rau cov iav fiber ntau.Cov txheej txheem no muaj ntau yam tsis zoo, xws li kev siv hluav taws xob siab, cov txheej txheem molding tsis ruaj khov thiab tsis muaj zog ua haujlwm, thiab yog qhov pib tshem tawm los ntawm cov tuam txhab loj iav fiber ntau.
Lub tank rauv hluav taws xob txoj kev siv hluav taws xob yog siv los yaj pyrophyllite thiab lwm yam khoom siv raw rau hauv iav tov hauv qhov cub.Tom qab cov npuas raug tshem tawm, lawv raug thauj mus rau lub qhov dej ntws los ntawm cov channel thiab raug kos rau hauv iav fiber ntau precursor ntawm kev kub ceev.Lub kiln tuaj yeem txuas ntau pua daim hlau los ntawm ntau txoj hauv kev rau kev tsim khoom ib txhij.Cov txheej txheem no yooj yim hauv cov txheej txheem, kev txuag hluav taws xob thiab kev txo qis, ruaj khov hauv kev tsim, muaj txiaj ntsig zoo thiab cov txiaj ntsig siab, uas yog qhov yooj yim rau kev tsim khoom loj loj thiab tau dhau los ua cov txheej txheem kev tsim khoom thoob ntiaj teb.Cov iav fiber ntau tsim los ntawm cov txheej txheem no suav nrog ntau dua 90% ntawm cov khoom siv thoob ntiaj teb.
Raws li Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Quo thiab Kev Txhim Kho Kev Txhim Kho ntawm Fiberglass Kev Lag Luam los ntawm 2022 txog 2026 tso tawm los ntawm Hangzhou Zhongjing Zhisheng Market Research Co., Ltd., raws li kev nthuav dav ntxiv ntawm COVID-19 thiab txuas ntxiv tsis zoo. Cov xwm txheej kev lag luam thoob ntiaj teb, cov iav fiber ntau thiab cov khoom lag luam tuaj yeem ua tiav cov txiaj ntsig zoo, ntawm ib sab, ua tsaug rau Tuam Tshoj txoj kev vam meej hauv kev tiv thaiv thiab tswj kev kis tus kab mob COVID-19, thiab lub sijhawm xa tawm ntawm kev lag luam hauv tsev, ntawm qhov tod tes, ua tsaug rau kev siv tas li ntawm cov iav fiber ntau cov xov paj tsim muaj peev xwm hauv kev lag luam, muaj tsawg dua cov haujlwm tshiab thiab lawv tau ncua sijhawm.Cov kab ntau lawm uas twb muaj lawm tau pib kho txias kom raws sijhawm thiab ncua sijhawm ntau lawm.Nrog rau kev loj hlob sai ntawm kev thov hauv kev lag luam qis qis thiab cua zog thiab lwm yam kev lag luam, ntau hom iav fiber ntau thiab cov khoom tsim tau ua tiav ntau yam ntawm cov nqi nce txij li peb lub hlis twg, thiab cov nqi ntawm qee cov iav fiber ntau cov khoom tau mus txog. los yog ze rau qib zoo tshaj plaws nyob rau hauv keeb kwm, tag nrho cov txiaj ntsig qib ntawm kev lag luam tau zoo tuaj.
iav fiber ntau tau tsim nyob rau hauv 1938 los ntawm ib lub tuam txhab Asmeskas;Thaum Tsov Rog Thoob Ntiaj Teb thib Ob hauv xyoo 1940s, cov iav fiber ntau cov khoom siv tau siv thawj zaug hauv kev lag luam tub rog (tso tank qhov chaw, dav hlau cabin, riam phom plhaub, tsho tiv thaiv phom, thiab lwm yam);Tom qab ntawd, nrog kev txhim kho txuas ntxiv ntawm cov khoom siv, kev poob qis ntawm cov nqi tsim khoom thiab kev txhim kho cov khoom siv hluav taws xob qis qis, daim ntawv thov ntawm iav fiber ntau tau nthuav dav mus rau pej xeem.Nws cov ntawv sau cia suav nrog kev tsim vaj tsev, kev tsheb nqaj hlau, kev tsheb nqaj hlau, petrochemical, tsheb tsim, aerospace, cua tsim hluav taws xob, khoom siv hluav taws xob, ib puag ncig engineering, marine engineering, thiab lwm yam, dhau los ua cov tiam tshiab ntawm cov khoom sib xyaw los hloov cov khoom siv xws li hlau, ntoo, pob zeb, thiab lwm yam, Nws yog lub teb chaws kev lag luam tawm tswv yim tawm tswv yim, uas yog qhov tseem ceeb rau kev lag luam hauv teb chaws, kev hloov pauv thiab kev txhim kho.
