Graphite hmoov yog ib yam khoom uas rhiab heev rau cov tshuaj tiv thaiv.Nyob rau hauv ib puag ncig sib txawv, nws cov resistivity yuav hloov, uas txhais tau hais tias nws tus nqi kuj yuav hloov.Txawm li cas los xij, muaj ib yam uas tsis hloov.Graphite hmoov yog ib qho zoo uas tsis yog xim hlau conductive.Ntev npaum li cov graphite hmoov khaws cia tsis cuam tshuam rau hauv cov khoom siv hluav taws xob, nws tseem yuav raug hluav taws xob zoo li cov hlau nyias.Txawm li cas los xij, tsis muaj tus lej tseeb rau tus nqi tiv thaiv, Vim tias cov tuab ntawm graphite hmoov sib txawv, tus nqi tsis kam ntawm graphite hmoov kuj yuav txawv thaum siv cov khoom sib txawv thiab ib puag ncig.Vim nws cov qauv tshwj xeeb, graphite muaj cov khoom tshwj xeeb hauv qab no:

1) Hom kub resistant: lub melting point ntawm graphite yog 3850 ± 50 ℃, thiab boiling point yog 4250 ℃.Txawm hais tias nws raug kub hnyiab los ntawm qhov kub siab kub arc, qhov poob qis thiab coefficient ntawm thermal expansion yog tsawg heev.Lub zog ntawm graphite nce nrog kub, thiab ntawm 2000 ℃, lub zog ntawm graphite ob npaug.
2) Conductivity thiab thermal conductivity: Cov conductivity ntawm graphite yog 100 lub sij hawm siab dua li cov minerals uas tsis yog hlau.Cov thermal conductivity tshaj cov khoom siv hlau xws li hlau, hlau, thiab txhuas.Lub thermal conductivity txo qis nrog qhov kub thiab txias, thiab txawm tias qhov kub siab heev, graphite ua ib qho insulator.
3) Lubricity: Lub lubrication kev ua tau zoo ntawm graphite nyob ntawm qhov loj ntawm graphite flakes.Qhov loj ntawm cov flakes, qhov me me ntawm kev sib txhuam coefficient, thiab qhov zoo ntawm lubrication kev ua tau zoo.
4) Chemical stability: graphite muaj tshuaj ruaj khov zoo ntawm chav tsev kub, thiab tuaj yeem tiv taus acid, alkali thiab organic hnyav corrosion.
5) Plasticity: Graphite muaj qhov toughness zoo thiab tuaj yeem txuas rau hauv cov ntawv nyias nyias.
6) Thermal shock resistance: Graphite tuaj yeem tiv taus qhov kub thiab txias hloov yam tsis muaj kev puas tsuaj thaum siv hauv chav sov.Thaum qhov kub thiab txias hloov pauv, qhov ntim ntawm graphite tsis hloov ntau thiab yuav tsis tawg.

1. Raws li cov ntaub ntawv refractory: graphite thiab nws cov khoom muaj cov khoom ntawm qhov kub thiab txias tsis kam thiab siab zog.Hauv kev lag luam metallurgical, nws tsuas yog siv los ua graphite crucibles.Hauv steelmaking, graphite feem ntau yog siv los ua tus neeg sawv cev tiv thaiv rau steel ingots thiab hauv ob sab phlu ntawm metallurgical rauv.
2. Raws li cov khoom siv hluav taws xob: siv hauv kev lag luam hluav taws xob los tsim cov khoom siv hluav taws xob, txhuam, cov pa roj carbon monoxide, cov roj carbon raj, cov electrodes zoo rau mercury zoo tam sim no transformers, graphite gaskets, xov tooj qhov chaw, coatings rau TV raj, thiab lwm yam.
3. Raws li cov khoom hnav-resistant lubricating: Graphite feem ntau yog siv los ua cov roj nplua nyeem hauv kev lag luam.Lubricating roj feem ntau tsis tuaj yeem siv nyob rau hauv high-speed, high-temperature, thiab high-pressure tej yam kev mob, thaum graphite hnav-resistant cov ntaub ntawv yuav ua hauj lwm yam tsis muaj lubricating roj nyob rau hauv siab zawv zawg speeds ntawm qhov kub ntawm 200 mus rau 2000 ℃.Ntau cov khoom siv thauj khoom corrosive yog dav siv los ntawm cov khoom siv graphite los ua lub khob piston, sealing rings, thiab bearings, uas tsis tas yuav ntxiv cov roj lubricating thaum ua haujlwm.Graphite emulsion kuj yog cov roj nplua nyeem zoo rau ntau cov hlau ua haujlwm (xov hlau, kos duab raj).
