Hom Graphite Blocks

Txhawm rau ua kom tau raws li kev tsim khoom tshwj xeeb thiab kev thov kev lag luam, graphite blocks muaj nyob rau hauv ntau hom. Raws li cov qauv nplej ntawm cov blocks, thawj qhov kev faib tawm ntawm graphite blocks tuaj yeem raug hu ua nplua, nruab nrab lossis ntxhib. Tsis tas li ntawd, nyob ntawm qhov purity, crystalline thiab cov khoom tshwj xeeb, graphite blocks tuaj yeem muab faib ua ntau hom.

 

Pyrolytic graphite blocks yog tsim los ntawm cov txheej txheem ntawm decomposition ntawm hydrocarbon gas, feem ntau methane, nyob rau hauv lub tshuab nqus tsev rauv kom nws purity. Cov txheej txheem tsim khoom no yog siv sijhawm ntev. Nyob rau hauv cov txheej txheem ntawm ntau lawm, methane los yog hydrocarbon gas yuav tsum tau rhuab saum toj no 2000 degrees nrog tsis tshua muaj siab kom cov graphite los nrog lub feature ntawm tsis-porous thiab yooj yim tshuab nws nto. Tom qab microcrystalline graphite yog tsim, nws muaj peev xwm tsim ib tug tuab aggregate ntawm me me ntuj graphite crystals nrog steel-grey xim thiab ci iab xim hlau. Txawm li cas los xij, amorphous graphite ib yam nkaus li nws lub npe, mos rau qhov kov. Hais txog tshuaj stability, thermal, kub tsis kam thiab hluav taws xob conductivity, amorphous graphite muaj kev ua tau zoo. Cov yam ntxwv no tuaj yeem haum zoo nrog casting, txheej, roj teeb, thiab cov khoom siv carbon. Sib txawv ntawm cov saum toj no ob graphite blocks, flake graphite blocks yog muab los ntawm ntuj graphite ncaj qha. Hom thaiv no muaj cov txheej txheem txheej uas cov pa roj carbon atoms tau teem rau hauv hexagonal lattice, nrog rau txhua txheej muaj cov pa roj carbon atoms. Cov khaubncaws sab nraud povtseg yog xoob ua ke, yog li ua kom cov blocks tuaj nrog qhov tsis zoo. Ib qho ntxiv graphite block yog hu ua isotropic graphite lossis hluavtaws graphite. Nws yog tsim los ntawm roj av coke thiab dav siv hauv kev siv hluav taws xob cia, xws li kev lag luam hnub ci. Ib daim ntawv thov tseem ceeb ntawm cov khoom siv hluavtaws graphite yog steel furnaces thiab aluminium smelters. Nws ua haujlwm rau kev tsav tsheb turbines, qhov twg cov hluav taws xob infrared lawv emit hloov mus rau hauv hluav taws xob. Xinhui Carbon yog tus kws tshaj lij hauv kev tsim cov khoom siv hluavtaws, xws li graphite rods thiab graphite blocks. Vim tias cov khoom lag luam tawm los ntawm peb lub Hoobkas ncaj qha, peb tuaj yeem muab koj cov khoom lag luam zoo ntawm tus nqi zoo.
