Graphite hmoov yog cov hmoov ntxhia, feem ntau yog tsim los ntawm cov ntsiab lus carbon, mos hauv kev ntxhib los mos, thiab xim dub grey;Nws muaj lub siab greasy thiab tuaj yeem ua rau daim ntawv.Lub hardness yog 1-2, thiab nws tuaj yeem nce mus rau 3-5 nrog kev nce ntawm impurities nyob rau hauv txoj kab ntsug.Lub ntiajteb txawj nqus yog 1.9 ~ 2.3.Nyob rau hauv cov xwm txheej ntawm cov pa cais tawm, nws cov ntsiab lus melting yog siab dua 3000 ℃, ua rau nws yog ib qho ntawm cov khoom siv kub tshaj plaws.Nyob rau hauv chav tsev kub, cov tshuaj lom neeg ntawm graphite hmoov yog qhov ruaj khov thiab insoluble hauv dej, dilute acids, dilute alkalis, thiab organic solvents;Cov khoom muaj qhov kub thiab txias tsis kam thiab conductivity, thiab tuaj yeem siv los ua cov khoom siv refractory, conductive, thiab hnav-resistant lubricating cov ntaub ntawv.

1. Siv los ua cov khoom siv refractory: Graphite thiab nws cov khoom muaj cov khoom ntawm qhov kub thiab txias thiab lub zog, thiab feem ntau yog siv hauv kev lag luam metallurgical los tsim graphite crucibles.Hauv steelmaking, graphite feem ntau yog siv los ua tus neeg sawv cev tiv thaiv rau steel ingots thiab ua ib lub hauv ob sab phlu rau metallurgical furnaces.

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).

Graphite muaj kev ruaj ntseg zoo.Tshwj xeeb ua tiav graphite muaj cov yam ntxwv ntawm corrosion kuj, zoo thermal conductivity, thiab tsis tshua muaj permeability, thiab yog dav siv nyob rau hauv zus tau tej cov tshav kub exchangers, cov tshuaj tiv thaiv tank, condensers, combustion towers, nqus yees, coolers, heaters, lim, thiab twj tso kua mis khoom.Kev siv dav hauv kev lag luam xws li petrochemical, hydrometallurgy, acid-base ntau lawm, hluavtaws fibers, papermaking, thiab lwm yam, nws tuaj yeem txuag tau ntau cov ntaub ntawv hlau.
