Fiberglass yog dab tsi?
Fiberglass yog dav siv vim lawv cov nqi-zoo thiab cov khoom zoo, feem ntau hauv kev lag luam composites.Raws li thaum ntxov xyoo pua 18th, cov neeg European pom tau hais tias iav tuaj yeem hloov mus rau hauv fibers rau kev xaws.Fiberglass muaj ob qho tib si filaments thiab luv fibers los yog flocs.Cov iav filaments feem ntau yog siv rau hauv cov ntaub ntawv sib xyaw, cov khoom siv roj hmab, cov khoom siv conveyor, tarpaulins, thiab lwm yam. Cov fibers luv luv feem ntau yog siv hauv cov ntaub ntawv tsis-woven, engineering plastics thiab cov ntaub ntawv sib xyaw.
Fiberglass txaus nyiam lub cev thiab txhua yam khoom, yooj yim ntawm fabrication, thiab tus nqi qis piv rau carbon fiber ua rau nws cov khoom ntawm kev xaiv rau high-kev ua tau zoo daim ntaub ntawv.Cov iav fibers yog tsim los ntawm oxides ntawm silica.Fiberglass muaj cov khoom siv zoo heev xws li tsis muaj nkig, siab zog, tsis tshua muaj zog thiab lub teeb yuag.
Fiberglass reinforced polymers muaj cov chav kawm loj ntawm ntau hom fiberglass, xws li longitudinal fibers, tws fibers, woven mats, thiab tws strand mats, thiab yog siv los txhim kho cov neeg kho tshuab thiab tribological zog ntawm polymer composites.Fiberglass tuaj yeem ua tiav qhov sib piv siab thawj zaug, tab sis brittleness tuaj yeem ua rau fibers tawg thaum ua.
Fiberglass zog
Cov yam ntxwv tseem ceeb ntawm fiberglass muaj xws li cov hauv qab no:
Tsis yooj yim rau nqus dej: Fiberglass yog cov tshuaj tiv thaiv dej thiab tsis haum rau cov khaub ncaws, vim hws yuav tsis nqus, ua rau cov neeg hnav ntub dej;vim tias cov khoom tsis cuam tshuam los ntawm dej, nws yuav tsis ntsws.
Inelasticity: Vim tsis muaj elasticity, cov ntaub muaj me ntsis inherent stretch thiab rov qab.Yog li ntawd, lawv xav tau kev kho saum npoo los tiv thaiv wrinkling.
Lub zog siab: Fiberglass muaj zog heev, yuav luag zoo li Kevlar.Txawm li cas los xij, thaum cov fibers rub tawm rau ib leeg, lawv tawg thiab ua rau cov ntaub ua rau lub ntsej muag shaggy.
Rwb thaiv tsev: Hauv daim ntawv luv fiber ntau, fiberglass yog ib qho zoo heev insulator.
Drapability: Cov fibers drape zoo, ua rau lawv zoo tagnrho rau curtains.
Thaum tshav kub kub Resistance: Cov iav fiber ntau yog kub resistant thiab tuaj yeem tiv taus kub txog 315 ° C, lawv tsis cuam tshuam los ntawm tshav ntuj, tshuaj dawb, kab mob, pwm, kab los yog alkalis.
Txaus siab: Fiberglass cuam tshuam los ntawm hydrofluoric acid thiab kub phosphoric acid.Txij li cov fiberglass yog cov khoom siv iav, qee cov fiberglass nyoos yuav tsum tau saib xyuas, xws li cov khoom siv rwb thaiv tsev hauv tsev, vim tias cov fibers kawg yog qhov tsis yooj yim thiab tuaj yeem tho rau ntawm daim tawv nqaij, yog li cov hnab looj tes yuav tsum hnav thaum tuav fiberglass.
Kev siv fiberglass
Fiberglass yog cov khoom siv tsis zoo uas tsis hlawv thiab khaws cia txog 25% ntawm nws lub zog pib ntawm 540 ° C.Feem ntau muaj cov iav me me ntawm fiberglass.Inorganic fibers yuav tsis pwm los yog deteriorate.Fiberglass cuam tshuam los ntawm hydrofluoric acid, kub phosphoric acid thiab cov khoom muaj zog.
Nws yog cov khoom siv hluav taws xob zoo heev.Cov ntaub fiber ntau muaj cov yam ntxwv ntawm cov av noo, siab zog, tsis muaj cua sov nqus thiab tsis tshua muaj dielectric, thiab yog cov khoom siv zoo tshaj plaws rau kev luam ntawv iav daim hlau thiab cov varnishes.
Qhov siab zog-rau-qhov hnyav piv ntawm fiberglass ua rau nws yog ib qho khoom siv zoo heev rau cov ntawv thov uas xav tau lub zog siab thiab qhov hnyav tsawg.Hauv daim ntawv textile, lub zog no tuaj yeem yog unidirectional lossis bidirectional, tso cai rau kev hloov pauv hauv kev tsim thiab nqi rau ntau yam kev siv hauv kev lag luam tsheb, kev tsim kho vaj tse, kev ua kis las, aerospace, marine, electronics, Tsev thiab cua zog.
