Kev kub-taws ntawm graphite foundt: tus hero ntawm kev tsis txaus ntseeg ntawm cov ntawv thov cua sov

Hauv kev lag luam uas kub siab rau qhov siab qhov siab, nrhiav cov ntaub ntawv uas tuaj yeem tiv thaiv cov cua sov thaum muab cov khoom muaj nuj nqi tseem ceeb. Qhov no yog qhov twgHigh-kub graphite muajcov kauj ruam rau hauv kev tsom teeb. Kab lus no ua ke mus rau hauv lub ntiaj teb ntawm graphite muaj, tshawb nws cov yam ntxwv, muaj ntau yam kev siv, thiab vim li cas nws thiaj li yuav yog tusCarbon thiab Graphitedaws koj twb nrhiav tau. Yog tias koj koom nrog kev lag luam zoo li metallurgy, rauv ua haujlwm, nyeem rau kom paub yuav ua li cas cov khoom siv dhau los tuaj yeem hloov kho koj txoj haujlwm.

1. Dab tsi yog graphite muaj thiab vim li cas nws yog qhov siab-kub superstar?

Graphite tau txais kev txaus siab, feem ntau tsis pom tab sis tseem ceeb heev nyob rau ntau qhov kev lag luam siab thiab kev lag luam hnyav. Xav txog qhov muag muag, ntaub npog, yooj yim, tab sis hloov cov paj rwb lossis ntaub plaub, nws yog tsim los ntawmpa roj carbonFibers, ua tiav ntawm qhov siab heevkublos uanpaimCov. Qhov kev hloov pauv no muab nws zoo tshaj plaws cov khoom, ua rau nws muaj tseeb kub superstar. Nws thov rau koob meej yog nws tshwj xeebThermal rwb thaiv tsevMuaj peev xwm, tshwj xeeb tshaj yog nyob rau hauv huab cua sov ib puag ncig. Xav txog cov chaw ua kom sov siv nyob rau hauv cov hlau mills lossis cov khoom siv tshwj xeeb hauv kev sim - cov chaw no xav tau cov ntaub ntawv uas yuav ua kom kub ua qhov twg nws yuav tsum yog, thiab qhov ntawd yog qhov tseebgraphite muaj kevexcrels ntawm.

Tab sis vim li casgraphite muaj kevYog li zoo ntawm kev tuav kub? Nws rhaub cia rau nws cov qauv txawv thiab muaj pes tsawg leeg. Tuspa roj carbonFibers, tom qab tau kho tshav kub, txhim kho cov qauv graphitic. Tus qauv no muabgraphite muaj kevmuaj kev sib xyaw ua ke ntawm cov yam ntxwv: nws yog lub teeb ci tseem muaj zog, yoog tau tsis ntev los, thiab tseem ceeb tshaj plaws, tsis txaus ntseeg rau siabkubCov. Piv rau ib txwmkev rwb thaiv tsevKhoom siv,graphite muaj kevtuaj yeem tiv taus ntau duakubtsis muaj kev txwv tsis pub lossis poob nwskev rwb thaiv tsevcov khoom. Qhov no ua rau nws tsis tseem ceeb hauv cov ntawv thov uas lwm cov khoom siv yuav tsuas yog yaj lossis swb. Ntxiv rau, qhov fibrous ntawm lubmuajCuab cov pa pa, ntxiv txhim kho nwsThermal rwb thaiv tsevmuaj peev xwm.

2. Rayon Graphite muaj kev zoo li vs. Pan Graphite Felt: Dab tsi yog qhov zoo rau koj?

Thaum koj pib saib mus rau hauvgraphite muaj kev, koj yuav ntsib ob hom loj:Rayon Graphite Muajthiab lauj kaubgraphite muaj kevCov. Ob qho tib si yog homCarbon thiab Graphite Zoo, tab sis lawv tau tsim los ntawm cov ntaub ntawv ua ntej prefursor -rayonThiab polyacrylonitrile (lauj kaub) fibers feem - thiab muaj me ntsis sib txawv, ua rau lawv haum rau cov ntawv thov sib txawv. Yog li, dab tsi yog qhov sib txawv tiag tiag, thiab koj xaiv li cas ntawm lawv?

Rayon Graphite Muajyog muab tau los ntawmrayon, lub cellulose fiber ntau. Thaumrayonfibers yog cov cua sov-kho nyob rau hauv tus txheej txheem hu ua carbonations thiab graphitization, lawv hloov mus uaRayon Graphite MuajCov.

Piv txwv li, nyob rau hauvLub Tshuab Nqus Tsev MetallurgyCov txheej txheem, tswj kom haumqho sothiab huab cua yog qhov tseem ceeb heev, thiabHigh carbon cov ntsiab lus graphite muajPab txhawb ua kom tiav qhov no.

5. Graphite muaj nyob rau hauv lub tshuab nqus tsev thiab cov roj hluav taws xob hluav taws xob: Ib qho kev sib tw uas muaj kev kub ntxhov?

Graphite muaj kevthiabLub tshuab nqus tsev ua kom sov thiab cov roj rauv rojyog tseeb ib qho kev sib tw zoo meej, ua lub pob zeb ntawm ntauKev kub siabMuaj cov txheej txheem. Cov khoom tshwj xeeb ntawmgraphite muaj kev, tshwj xeeb nws zoo heevthermal rwb thaiv tsev nyob rau hauv nqus tsev thiab inertatmospheres thiab kuj mus rau huabkub, ua nws qhov tsis tseem ceeb tiv thaiv nyob rau hauv cov homlub tshuab ziabCov. Xav tias nws sim ua haujlwm aLub Tshuab Cua Sovtsis muaj lub siabkev rwb thaiv tsev- nws yuav yog lub zog kawg-ua tau zoo thiab nyuaj rau kev tswj hwm qhov yuav tsum tau uaqho so.

HauvLub tshuab nqus tsev, qhov tsis muaj cua tshem tawm cov cua sov hloov mus los ntawm convection thiab conduction ntawm gases. Radiant cua sov hloov pauv ua tus qauv.Graphite muaj kev, nrog nws qhov qisthermal conductivitythiab muaj peev xwm nqus tau thiab tawg cov cua sov, ua raws li qhov ua tau zooThermal rwb thaiv tsevCov. Nws me me poob los ntawm thaj chaw kub, tso cai rauqho cubmus cuag thiab tswj siabkubnrog cov tswv yim tsawg dua. Ib yam li ntawd, hauvInert Roj Furnaces, qhov twg ainert gasZoo li Argon lossis nitrogen yog siv los tiv thaiv oxidation,graphite muaj kevmuab qhov tseem ceebThermal rwb thaiv tsevthaum tseem tau sib haum nrog lubInert cuaCov. Tusinert gasntxiv mus txhim kho lub neej ntawm covgraphite muaj kevlos ntawm kev tiv thaiv nws los ntawm oxidizing ntawm siabkub.

Kev sivgraphite muaj kevhauvLub tshuab nqus tsev ua kom sov thiab cov roj rauv rojyog thoob plaws hla ntau yam kev lag luam, suav nrogmetallurgy, lub ceramatorsUa, thiab cov ntaub ntawv qib siab ua haujlwm. Los ntawm tshav kub-kho lub nkoj hauvLub tshuab nqus tsevrau sinining ceramics nyob rau hauvInert Roj Furnaces, graphite muaj kevua kom muaj txiaj ntsig zoo thiab txhim khu kev qhaKev kub siabua. Nws lub peev xwm los tiv thaiv huabkubHauv cov kev tswj hwm no ua rau nws cov ntaub ntawv tsis txaus ntseeg rau cov ntawv thov no. Kev sib xyaw ntawmgraphite muaj kevthiab tswj cualub tshuab ziabenables meejqho soKev tswj hwm thiab lub zog ua tau zoo, uas yog qhov tseem ceeb rau kev tsim cov ntaub ntawv zoo thiab cov khoom siv.

6. Dab tsi ua graphite tau txais ib cov khoom zoo tshaj plaws rau cov ntawv thov thermal condicity?

Thaumgraphite muaj kevyog feem ntau paub txog nwsThermal rwb thaiv tsev, nws tseem yuav nthuav tawm txaus nyiamthermal conductivityCov khoom uas muaj txiaj ntsig zoo hauv cov ntawv thov tshwj xeeb. Txawm hais tias nwsthermal conductivityyog qis dua cov khoomnpaim, nws tseem tseem ceebsiab duatshaj lwm yamkev rwb thaiv tsevCov ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv qee cov lus qhia. Qhov no cov xeeb ceem tshwj xeeb no ua rau nws muaj txiaj ntsig hauv cov xwm txheej uas ob leegThermal rwb thaiv tsevThiab tswj cua sov dissipation yog qhov yuav tsum tau ua.

TusThermal conductivity ntawm graphite muajyog anisotropic, lub ntsiab lus nws yuav txawv nyob ntawm cov kev taw qhia ntawm kub txaus. Kub ua kom sov yog ntau dua nyob rau hauv lub dav hlau ntawm lubmuajtxheej tshaj li ntawm cov tuab. Qhov kev qhia nothermal conductivitytuaj yeem ua tau zoo nyob rau hauv cov ntawv thov uas kub yuav tsum tau kis tawm tawm lossis channeled hauv ib qho kev taw qhia thaum tseem muab tag nrhoThermal rwb thaiv tsevCov. Piv txwv li, hauv qeeroj teebtsim qauv lossis kev hloov pauv kub,graphite muaj kevtuaj yeem siv los coj los ua kom sov deb ntawm qhov tseem ceeb ntawm cov khoom siv thaum tib lub sijhawminsulatingcov chaw ib puag ncig.

Tsis tas li ntawd, tusthermal conductivityntawmgraphite muaj kevtuaj yeem ua kom haum rau qee yam los ntawm kev kho cov kev qhia fiber ntau, ntom ntom, thiab ua cov tsis ua haujlwm thaum tsim khoom. Qhov no tso cai rau cov engineers kom zoo-tune lubthermalkev ua tau zoo ntawmgraphite muaj kevrau cov kev xav tau tshwj xeeb. Thaum tsis yog heevua hauj lwmli tawvGraph kaw electrodeKhoom siv,graphite lawv muajkev sib xyaw ntawm kev muaj pes tsawgthermal conductivitythiab zoo heevThermal rwb thaiv tsevQhib cov kev yeem tshwj xeeb hauvthermalKev Tswj thiab Kev Siv Hluav Taws Xob, tshwj xeeb hauvKev kub siabthiab tswj cov chaw puag ncig cua. Nws yooj yoog thiab ua tau zoo tseem cia nws siv rau hauv cov duab sib xyaw thiab cov chaw uas ruaj khovnpaimtej zaum yuav yog impractical.
