Fiberglass yog dab tsi?
Fiberglass siv dav vim lawv cov nqi tsim nyog thiab cov khoom zoo, feem ntau hauv kev lag luam composites. Thaum ntxov li xyoo pua 18th, cov neeg European tau paub tias iav tuaj yeem raug tig mus rau hauv cov fibers rau kev weaving. Fiberglass muaj ob qho tib si filaments thiab luv luv fibers lossis flocs. Iav filaments feem ntau siv rau hauv cov ntaub ntawv sib xyaw, cov khoom roj hmab, cov siv conveyor, tarpaulins, thiab lwm yam. Luv luv fibers feem ntau yog siv rau hauv cov felts tsis-woven, engineering plastics thiab cov ntaub ntawv sib xyaw.
Cov fiberglass zoo nkauj lub cev thiab cov khoom siv kho tshuab, yooj yim ntawm kev tsim khoom, thiab tus nqi qis piv rau carbon fiber ua rau nws yog cov khoom siv xaiv rau kev siv cov khoom sib xyaw ua ke siab. Cov iav fibers yog tsim los ntawm oxides ntawm silica. Fiberglass muaj cov khoom siv kho tshuab zoo heev xws li tsis tshua muaj brittle, muaj zog siab, tsis tshua muaj zog thiab lub teeb yuag.
Cov polymers fiberglass uas muaj zog muaj ntau hom fiberglass sib txawv, xws li cov fibers ntev, cov fibers txiav, cov lev woven, thiab cov lev txiav, thiab siv los txhim kho cov khoom siv kho tshuab thiab tribological ntawm cov polymer composites. Fiberglass tuaj yeem ua tiav qhov sib piv siab thaum pib, tab sis brittleness tuaj yeem ua rau cov fibers tawg thaum lub sijhawm ua.
Cov khoom fiberglass
Cov yam ntxwv tseem ceeb ntawm fiberglass muaj xws li cov hauv qab no:
Tsis yooj yim rau nqus dej: Fiberglass yog cov dej tsis haum thiab tsis haum rau khaub ncaws, vim tias hws yuav tsis nqus, ua rau tus neeg hnav xav tias ntub; vim tias cov khoom tsis cuam tshuam los ntawm dej, nws yuav tsis ntsws.
Kev Tsis Ywj Pheej: Vim tsis muaj qhov ywj pheej, cov ntaub tsis tshua muaj kev ncab thiab rov qab zoo. Yog li ntawd, lawv xav tau kev kho kom zoo nkauj kom tiv taus kev ntsws.
Muaj Zog Heev: Fiberglass muaj zog heev, yuav luag muaj zog npaum li Kevlar. Txawm li cas los xij, thaum cov fibers sib txhuam rau ib leeg, lawv tawg thiab ua rau cov ntaub zoo li shaggy.
Kev rwb thaiv tsev: Hauv daim ntawv luv luv, fiberglass yog ib qho insulator zoo heev.
Drapability: Cov fibers drape zoo, ua rau lawv zoo tagnrho rau cov ntaub thaiv qhov rai.
Kev Tiv Thaiv Kub: Cov iav fibers yog cov cua sov heev thiab tuaj yeem tiv taus qhov kub txog li 315 ° C, lawv tsis cuam tshuam los ntawm lub hnub ci, tshuaj dawb, kab mob, pwm, kab lossis alkalis.
Muaj Kev Cuam Tshuam: Fiberglass raug cuam tshuam los ntawm hydrofluoric acid thiab kub phosphoric acid. Vim tias cov fiber yog cov khoom ua los ntawm iav, qee cov fiberglass nyoos yuav tsum tau ua tib zoo saib xyuas, xws li cov ntaub ntawv rwb thaiv tsev hauv tsev, vim tias cov fiber kawg tsis yooj yim tawg thiab tuaj yeem tho qhov tawv nqaij, yog li yuav tsum hnav hnab looj tes thaum tuav fiberglass.
Kev siv fiberglass
Fiberglass yog ib yam khoom inorganic uas tsis kub hnyiab thiab khaws cia li 25% ntawm nws lub zog pib ntawm 540 ° C. Feem ntau muaj cov iav me ntsis cuam tshuam rau fiberglass. Cov fibers inorganic yuav tsis pwm lossis lwj. Fiberglass raug cuam tshuam los ntawm hydrofluoric acid, kub phosphoric acid thiab cov tshuaj muaj zog.
Nws yog cov khoom siv hluav taws xob zoo heev. Cov ntaub fiber muaj cov yam ntxwv ntawm cov av noo siab, lub zog siab, kev nqus cua sov tsawg thiab dielectric tsis tu ncua qis, thiab yog cov khoom siv txhawb nqa zoo tshaj plaws rau kev luam ntawv iav phaj thiab cov xim pleev xim rwb thaiv tsev.
Qhov sib piv ntawm lub zog siab rau qhov hnyav ntawm fiberglass ua rau nws yog cov 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 ywj pheej hauv kev tsim qauv thiab tus nqi rau ntau yam kev siv hauv kev lag luam tsheb, kev tsim kho pej xeem, cov khoom siv kis las, aerospace, marine, electronics, Tsev thiab cua zog.
