Dab tsi yog fiberglass?
Fiberglass tau siv dav vim lawv cov nqi-ua tau zoo thiab cov khoom zoo, feem ntau yog nyob rau hauv kev lag luam sib xyaw. Thaum ntxov li xyoo 18th, cov neeg European pom tau tias iav tuaj yeem spun mus rau hauv cov fibers rau weavers. Fiberglass muaj ob qho tib si filaments thiab luv luv fibers lossis flocs. Cov khoom siv iav uas siv tau siv nyob rau hauv cov khoom siv sib xyaw, cov khoom siv roj hmab, cov khoom siv roj hmab, thiab lwm yam.
Fiberglass txaus nyiam lub cev thiab cov tshuab siv, yooj yim ntawm cov roj ntsha, thiab tus nqi qis rau cov roj carbon fiber ntau ua rau nws cov khoom siv cov kev xaiv siab sib xyaw. Cov iav fibers yog tsim los ntawm oxides ntawm silica. Fiberglass muaj cov kws kho tshuab zoo tshaj plaws xws li muaj qhov loj dua, lub zog siab, qis tawv thiab lub teeb yuag.
Fiberglass txhawb cov polymers muaj cov chav kawm sib txawv ntawm cov ntaub ntawv sib txawv, thiab siv cov khoom siv ua haujlwm ntev, thiab cov khoom siv kev ua phem ntawm cov khoom sib xyaw polymer. Cov fiberglass tuaj yeem ua tiav qhov kev ua tiav zoo siab, tab sis brittleness yuav ua rau cov fibers tawg thaum ua.
Cov Khoom Siv Fiberglass
Cov yam ntxwv tseem ceeb ntawm fiberglass muaj xws li cov hauv qab no:
Tsis yooj yim rau nqus dej: fiberglass yog dej tshuaj thiab tsis haum rau cov khaub ncaws, vim tias hws yuav tsis nqus, ua rau cov ntoo xav ntub; Vim tias cov khoom siv tsis cuam tshuam los ntawm dej, nws yuav tsis ntsws.
Inelastasticity: vim tsis muaj elasticity, cov ntaub muaj me me thiaj li ncab thiab rov qab. Yog li ntawd, lawv xav tau kev kho deg kom tiv thaiv wrinkling.
Lub zog siab: fiberglass yog qhov muaj zog heev, yuav luag muaj zog li kev muag muag. Txawm li cas los xij, thaum cov fibers rub tawm tsam ib leeg, lawv tawg thiab ua rau cov ntaub los noj ntawm cov tsos mob shaggy.
Rwb thaiv tsev: nyob rau hauv luv luv fiber ntau daim ntawv, fiberglass yog ib qho zoo heev insulator.
Drapability: cov fibers drape zoo, ua rau lawv zoo tagnrho rau cov ntaub.
Thaum tshav kub kub ua: cov iav fibers yog cov cua sov kub heev thiab tuaj yeem tiv thaiv kub, lawv tsis muaj kev cuam tshuam los ntawm lub hnub ci, tshuaj dawb, pwm, kab lossis alkalis.
Muaj kev raug: fiberglass cuam tshuam los ntawm hydrofloflic acid thiab kub phosphoric acid. Txij li thaum muaj fiber ntau yog cov khoom siv iav, qee cov ntaub tawv nqaij nyoos yuav tsum tau kho cov ntaub ntawv hauv tsev neeg, yog li cov hnab looj tes ua haujlwm hauv tsev, yog li cov hnab looj tes yog cov hnab looj tes, yog li cov hnab looj tes, yog li cov hnab looj tes kom zoo li cov tawv nqaij, yog li cov hnab looj tes ua ke, yog li cov hnab looj tes ua ke,
Daim Ntawv Thov Ntawm Fiberglass
Fiberglass yog cov khoom siv inorganic uas tsis hlawv thiab khaws tau txog 25% ntawm nws lub zog thawj ntawm 540 ° C. Feem ntau muaj me me iav nyhuv ntawm fiberglass. Inorganic fibers yuav tsis pwm lossis tsis zoo. Cov fiberglass raug cuam tshuam los ntawm hydrofluoric acid, kub phosphoric acid thiab muaj zog tshuaj.
Nws yog ib qho khoom siv hluav taws xob zoo heev. Cov ntaub npuag fiber ntau muaj cov yam ntxwv ntawm cov av noo, lub zog muaj zog, qis dielectric tas li rau cov luam ntawv iav daim hlau thiab insulating varnishes.
Lub zog muaj zog-rau-qhov hnyav piv ntawm fiberglass ua rau nws muaj cov khoom siv tau zoo rau kev siv lub zog siab thiab qhov hnyav tsawg. Nyob rau hauv daim ntawv nyeem, lub zog no tuaj yeem tsis sib xws lossis kev siv nyiaj hauv kev tsim qauv hauv kev tsim kho tsheb, kev ua kis las, kev ntaus pob ncaws pob, lub tsev thiab cua lub zog.
