Fiberglass yog ib hom khoom siv inorganic uas tsis yog hlau uas muaj kev ua tau zoo heev, ntau yam zoo yog kev rwb thaiv tsev zoo, tiv taus cua sov zoo, tiv taus corrosion zoo, muaj zog kho tshuab siab, tab sis qhov tsis zoo yog brittle, tsis hnav tsis kam. Cov khoom siv tseem ceeb ntawm kev tsim cov iav fiber yog: quartz xuab zeb, alumina thiab pyrophyllite, limestone, dolomite, boric acid, soda tshauv, glauberite, fluorite thiab lwm yam. Txoj kev tsim khoom yog muab faib ua ob pawg: ib qho yog ua cov iav fused ncaj qha rau hauv fiber; Ib qho yog ua cov iav molten rau hauv lub pob iav lossis pas nrig nrog txoj kab uas hla ntawm 20 hli, thiab tom qab ntawd ua cov fiber zoo heev nrog txoj kab uas hla ntawm 3-80μm tom qab cua sov thiab rov yaj dua ntau txoj kev. Cov fiber tsis kawg uas kos los ntawm txoj kev kos duab los ntawm platinum alloy phaj hu ua fiberglass txuas ntxiv, feem ntau hu ua fiber ntev. Cov fiber tsis txuas ntxiv ua los ntawm cov menyuam lossis cua ntws hu ua fiberglass ntev, feem ntau hu ua fiber luv luv. Lub cheeb ntawm nws cov monofilaments yog ntau microns rau ntau tshaj nees nkaum microns, sib npaug rau 1 / 20-1 / 5 ntawm tib neeg cov plaub hau, thiab txhua pob ntawm cov fiber filaments yog tsim los ntawm ntau pua lossis txawm tias ntau txhiab tus monofilaments. Fiberglass feem ntau yog siv ua cov ntaub ntawv txhawb nqa hauv cov ntaub ntawv sib xyaw, cov ntaub ntawv rwb thaiv tsev hluav taws xob thiab cov ntaub ntawv rwb thaiv tsev thermal, roadbed panels thiab lwm yam teb ntawm lub teb chaws kev lag luam.
Cov yam ntxwv ntawm fiberglass yog raws li nram no:
(1) Lub zog tensile siab, me me elongation (3%).
(2) Cov coefficient elastic siab thiab rigidity zoo.
(3) Lub zog loj thiab lub zog tensile siab nyob rau hauv qhov txwv elastic, yog li qhov nqus ntawm lub zog cuam tshuam loj heev.
(4) Cov fiber inorganic, tsis kub hnyiab, tshuaj lom neeg zoo.
(5) Kev nqus dej tsawg.
(6) Qhov ruaj khov ntawm qhov ntsuas thiab kev tiv thaiv cua sov zoo.
(7) Kev ua tau zoo, tuaj yeem ua rau hauv cov xov, cov pob khoom, cov ntaub, cov ntaub woven thiab lwm yam khoom sib txawv.
(8) Pob tshab los ntawm lub teeb.
(9) Kev ua raws li zoo nrog cov tshuaj resin.
(10) Tus nqi pheej yig.
(11) Nws tsis yooj yim hlawv thiab tuaj yeem yaj ua cov hlaws iav ntawm qhov kub siab.
