Fiberglass yog dab tsi?

Fiberglassyog ib yam khoom siv inorganic uas tsis yog hlau nrog cov yam ntxwv zoo heev. Nws muaj ntau hom thiab muaj cov txiaj ntsig xws li kev rwb thaiv tsev zoo, tiv taus cua sov siab, tiv taus xeb zoo, thiab muaj zog kho tshuab siab.

Cov iav fiber yog tsim los ntawm cov zaub mov xws li micaceous shale, kaolin, limestone, thiab quartz xuab zeb los ntawm cov txheej txheem suav nrog kev yaj kub siab, kos duab, ziab, thiab winding. Lub cheeb ntawm ib txoj hlua yog txij li ob peb micrometers mus rau ntau tshaj nees nkaum micrometers, uas yog sib npaug rau 1/20 txog 1/5 qhov tuab ntawm tib neeg cov plaub hau.

Hauv lus yooj yim, cov iav fiber yog "ultra-fine glass filaments" kos los ntawm iav kom nyias dua li cov plaub hau tib neeg ntau zaus.

Hom Iav Fiber

Raws li cov alkali hauv cov iav, cov iav fiber tuaj yeem muab faib ua cov iav fiber tsis muaj alkali (E-iav), cov iav fiber nruab nrab-alkali (C-iav), thiab cov iav fiber siab-alkali. Ntawm cov no, E-iav yog qhov muaj ntau tshaj plaws, suav txog ntau dua 95% ntawm tag nrho cov khoom lag luam hauv kev lag luam.

Los ntawm daim ntawv thov, lawv tuaj yeem raug cais ua cov iav fibers hluav taws xob thiab cov iav fibers industrial.

Cov khoom siv iav fiber qib hluav taws xob feem ntau suav nrog cov xov hluav taws xob thiab daim ntaub hluav taws xob, uas siv rau hauv cov laug cam luam tawm (PCBs), cov ntawv laminates tooj liab (CCLs), thiab cov ntaub ntawv ceev ceev, thiab suav tias yog cov iav fibers zoo tshaj plaws.

Cov iav fiber ntau hauv hluav taws xob feem ntau yog muab faib ua thawj-, thib ob-, thiab thib peb tiam ntaub.

Cov ntaub thawj tiam feem ntau yog ua los ntawm cov iav E-iav ib txwm muaj, muab kev hloov pauv zoo thiab siv rau hauv cov PCBs thiab cov khoom siv hluav taws xob.

Cov ntaub tiam thib ob yog cov ntaub iav fiber uas tsis muaj dielectric ntau, tsis muaj kev poob (Low-Dk/Df), nrog rau cov khoom dielectric thiab kev poob zoo dua li cov ntaub tiam thawj, ua rau muaj kev sib kis teeb liab ruaj khov dua. Lawv siv rau hauv cov PCB nruab nrab mus rau qib siab, cov servers nruab nrab mus rau qib siab, 5G/6G chaw nres tsheb, thiab cov khoom siv hluav taws xob hauv tsheb.

Qhov qis dua ntawm dielectric constant (Dk), qhov ceev ntawm lub teeb liab hluav taws xob mus ncig; qhov qis dua ntawm dielectric poob (Df), qhov tsawg dua ntawm lub teeb liab poob, thiab qhov qis dua ntawm kev tsim cua sov.

Cov ntaub tiam thib peb yog cov ntaub fiber ntau Dk/Df quartz iav uas tsis tshua muaj zog heev, tseem hu ua Q (Quartz) ntaub. Nws yog siv rau hauv kev sib txuas lus siab thiab ceev ceev, AI servers, kev siv RF siab, thiab cov khoom siv ntim khoom siab, thiab tam sim no yog cov khoom siv tseem ceeb rau cov khoom siv hluav taws xob siab.

Cov khoom fiberglass qib kev lag luam suav nrog roving, chopped strand, surface felt, woven fabric, unidirectional fabric, thiab glass wool, uas yog siv rau hauv cov hniav cua turbine, cov ntaub ntawv tsim kho, tsheb, thiab cov kav dej.

Raws li cov iav muaj pes tsawg leeg, cov iav fiber ntau hauv kev lag luam tau muab faib ua:E (Hluav Taws Xob) iav, uas yog qhov tseem ceeb tshaj plaws; C (Tshuaj lom neeg) iav, uas muaj kev tiv thaiv kua qaub zoo heev thiab siv rau hauv cov kav dej tshuaj lom neeg, cov thoob dej cia khoom, thiab cov ntawv thov zoo sib xws; S (High-Strength)/R (Reinforcement) iav, siv rau hauv aerospace, cov thoob roj siab, thiab cov ntawv thov fais fab cua siab; thiab HM (High Modulus) iav, siv rau hauv cov hniav cua loj thiab cov ntawv thov zoo sib xws.

Cov Cheeb Tsam Siv Cov Iav Fiber

Cov chaw thov tseem ceeb ntawm cov iav fiber thiab lawv cov lag luam sib koom ua lag luam yog raws li nram no: cov khoom siv hauv tsev thiab cov ntaub ntawv tsim kho (25%), kev thauj mus los (24%), khoom siv hluav taws xob thiab hluav taws xob (18%), lub zog thiab kev tiv thaiv ib puag ncig (14%), cov khoom siv rau cov neeg siv khoom (8%), thiab lwm yam (11%) (suav nrog kev lag luam marine, aerospace, thiab kev siv kho mob).

Cov no suav nrog cov chaw siv uas hloov pauv tas li (cov ntaub ntawv tsim kho, cov khoom siv hauv kev lag luam, thiab lwm yam) nrog rau cov chaw siv tshiab (kev siv lub teeb tsheb, 5G, lub zog cua, photovoltaics), yog li kev lag luam fiberglass muaj ob qho tib si "cyclical" thiab "kev loj hlob".

Vim li cas tus nqi thiaj nce siab?

Tsis ntev los no, cov nqi ntawm cov iav fiber tau nce ntxiv mus, thiab qee yam khoom kuj tsis tshua muaj. Qhov no yog vim muaj peb yam tseem ceeb sib xyaw ua ke: kev thov ntau ntxiv, kev txwv tsis pub muab khoom ntau, thiab cov nqi nce ntxiv - ib qho qauv uas zoo ib yam li cov nqi ntawm cov chips nco.

Nyob rau sab kev thov, kev loj hlob sai heev hauv cov khoom lag luam siab tau dhau los ua lub hauv paus tseem ceeb. AI servers tau ua rau muaj kev thov ntau ntxiv rau cov ntaub ntawv hluav taws xob siab, nrog rau kev siv cov iav fiber ib PCB hauv ib lub AI server ntau dua li ntawm lub server txheem ntau dua ob npaug. Tib lub sijhawm, qhov sib txawv ntawm cov hniav cua loj dua thiab kev ua kom lub zog tshiab hnyav dua tab tom nrawm dua, ua rau kev thov kev lag luam tag nrho thiab tsim kom muaj thaj chaw uas muaj "kev tsis txaus ntawm cov khoom lag luam siab thiab kev sib npaug ntawm cov khoom lag luam ib txwm muaj."

Nyob rau sab kev muab khoom, kev ywj pheej tsawg ua rau nws nyuaj rau ua raws li kev loj hlob ntawm kev thov.Cov chaw tsim khoom fiberglasstau hloov kho lawv cov khoom lag luam sai sai, hloov lub peev xwm ib txwm mus rau cov ntaub fiberglass tshwj xeeb uas muaj nqi siab, uas ua rau muaj kev txo qis hauv kev muab cov ntaub hluav taws xob txheem. Ntxiv mus, lub voj voog xa khoom rau cov khoom siv tseem ceeb siv hauv kev tsim cov ntaub hluav taws xob siab yog ntev li 18-24 lub hlis, ua rau kev hloov pauv hauv tsev tsis yooj yim sua hauv lub sijhawm luv luv. Ua ke nrog cov khoom lag luam qis, qhov no tau tsim kev tsis sib npaug ntawm kev muab khoom thiab kev thov.

Nyob rau sab nqi, kev nyuaj siab ntawm tus nqi ua rau cov tuam txhab yuav tsum nce tus nqi. Tus nqi ntawm platinum, uas yog cov khoom siv tseem ceeb, tau nce siab heev, thaum cov khoom siv pabcuam xws li illite tau nce siab ua ke, ua rau cov nyiaj tau los ntawm cov tuam txhab tsawg zuj zus. Kev nce tus nqi tau dhau los ua qhov kev xaiv tsis tau rau cov tuam txhab kom ua haujlwm li qub. Ntxiv mus, kev qeeb ntawm kev nthuav dav ntawm peev xwm hauv kev lag luam ua rau tus nqi nce ntxiv.
