Graphite, ib daim ntawv zoo tshaj plaws ntawm cov pa roj carbon, tau ntev tau lees paub rau nws cov khoom tshwj xeeb thiab dav - daim ntawv thov. Raws li ib qho ntawm cov khoom lag luam graphite, kuv feem ntau ntsib cov lus nug los ntawm peb cov neeg siv khoom: "Cov khoom siv graphite feem ntau kav ntev npaum li cas?" Hauv qhov blog no, kuv yuav delve rau hauv cov xwm txheej uas cuam tshuam rau lub neej ntawm cov khoom lag luam graphite thiab muab qee qhov kev nkag siab raws li peb cov kev paub dhau los hauv kev lag luam.
Cov khoom ntawm Graphite uas cuam tshuam rau lub neej ntev
Graphite muaj ntau yam khoom siv uas ua rau nws muaj zog. Ua ntej thiab foremost, nws muaj lub siab melting point, nyob ib ncig ntawm 3600 degree. Qhov no ua rau nws haum rau cov ntawv thov nyob rau hauv siab - qhov kub thiab txias, xws li hauv Graphite Melting Crucible. Lub siab melting point txhais tau hais tias graphite tuaj yeem tiv taus cua sov yam tsis muaj melting lossis deforming yooj yim, uas yog qhov tseem ceeb rau nws ntev - siv nyob rau hauv cov txheej txheem xws li hlau melting thiab casting.
Lwm yam khoom tseem ceeb yog nws cov tshuaj lom neeg ruaj khov. Graphite yog qhov tsis muaj zog thiab tiv taus ntau yam tshuaj, acids, thiab alkalis. Cov tshuaj tiv thaiv no tso cai rau cov khoom siv graphite siv rau hauv qhov chaw corrosive yam tsis muaj kev puas tsuaj loj. Piv txwv li, nyob rau hauv cov tshuaj ua cov nroj tsuag, graphite Cheebtsam yuav siv tau los lis ntau yam corrosive tshuaj, thiab lawv ntev - ntev kev ua tau zoo muaj nuj nqis heev.
Graphite kuj muaj thermal conductivity zoo. Cov cuab yeej no pab ua kom cov cua sov sib npaug, txo qhov kev pheej hmoo ntawm thermal stress thiab cracking. Hauv cov ntawv thov uas yuav tsum tau hloov cov cua sov sai, xws li hauv cov khoom siv hluav taws xob ua los ntawm graphite, qhov thermal conductivity no ua rau cov khoom siv tau ntev los ntawm kev tiv thaiv overheating thiab kev puas tsuaj.
Cov yam ntxwv cuam tshuam rau lub neej ntawm cov khoom siv graphite
Cov xwm txheej ua haujlwm
Cov kev ua haujlwm ua haujlwm ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab ntev npaum li cas cov khoom graphite yuav kav ntev. Qhov kub thiab txias yog ib qho tseem ceeb tshaj plaws. Yog tias cov khoom siv graphite yog siv los ntawm qhov kub thiab txias ze rau nws qhov kev txwv siab tshaj plaws rau lub sijhawm ntev, nws tuaj yeem ua rau thermal degradation. Piv txwv li, nyob rau hauv qhov kub siab - qhov cub, qhov kub thiab txias tsis tu ncua tuaj yeem ua rau cov graphite oxidize. Oxidation ntawm graphite tshwm sim thaum nws reacts nrog oxygen ntawm qhov kub thiab txias, ua rau poob phaus thiab txo cov neeg kho tshuab lub zog.
Lub xub ntiag ntawm reactive gases los yog tshuaj nyob rau hauv kev khiav hauj lwm ib puag ncig kuj muaj feem xyuam rau lub lifespan ntawm graphite khoom. Nyob rau hauv cov txheej txheem tsim tshuaj, yog tias cov graphite raug rau cov pa roj ntau heev lossis cov kua qaub uas muaj zog, nws yuav raug tshuaj lom neeg uas tuaj yeem ua rau cov khoom tawg dhau sijhawm. Piv txwv li, nyob rau hauv chlorine - ib puag ncig nplua nuj, graphite yuav hnov mob nrog cov tshuaj chlorine los ua cov tshuaj tsis haum, ua rau cov graphite hnav mus.
Mechanical stress yog lwm yam tseem ceeb. Yog tias cov khoom lag luam graphite raug cov khoom siv ntau dhau, xws li kev kub siab lossis cuam tshuam, nws yuav tawg lossis tawg. Hauv cov ntawv thov uas siv cov khoom siv graphite hauv cov tshuab, kev teeb tsa tsis raug lossis kev ua haujlwm tuaj yeem ua rau muaj kev puas tsuaj. Piv txwv li, hauv graphite - lined twj tso kua mis, yog tias lub twj tso kua mis tsis zoo, nws tuaj yeem ua rau tsis sib xws ntawm cov graphite hauv ob sab phlu, txo nws txoj sia.
Khoom Zoo
Qhov zoo ntawm cov khoom graphite nws tus kheej yog qhov tseem ceeb ntawm nws txoj kev ua neej ntev. High - cov khoom graphite zoo yog tsim los ntawm cov ntaub ntawv ntshiab graphite nrog tsawg impurities. Cov impurities nyob rau hauv graphite tuaj yeem ua raws li cov ntsiab lus tsis muaj zog, txo qhov zuag qhia tag nrho lub zog thiab tshuaj tiv thaiv ntawm cov khoom. Piv txwv li, yog tias graphite crucible muaj cov impurities siab, nws yuav ua rau tawg ntau dua thaum lub sij hawm cua sov thiab cua txias.
Cov txheej txheem tsim khoom kuj tseem cuam tshuam qhov zoo ntawm cov khoom graphite. Cov txheej txheem tsim khoom siab heev tuaj yeem ua kom muaj cov qauv zoo sib xws thiab cov khoom siv kho tshuab zoo dua. Piv txwv li, hauv kev tsim cov High Ntshiab Graphite Parts, precision machining thiab kev kho cua sov txheej txheem tuaj yeem txhim kho qhov ceev thiab lub zog ntawm graphite, ua rau nws ruaj khov dua.
Kev tu thiab tu
Kev tu thiab kev saib xyuas kom zoo tuaj yeem txuas ntxiv lub neej ntawm cov khoom graphite. Kev tshuaj xyuas tsis tu ncua yog qhov tseem ceeb txhawm rau txheeb xyuas cov cim qhia ntawm kev puas tsuaj lossis hnav thaum ntxov. Piv txwv li, nyob rau hauv lub graphite tshav kub exchanger, tsis tu ncua kev soj ntsuam xyuas yuav pab tau txheeb xyuas tej kab nrib pleb los yog leaks nyob rau hauv lub graphite hlab. Yog tias kuaj pom ntxov, kev puas tsuaj me tuaj yeem kho tau, tiv thaiv kev puas tsuaj ntxiv.
Kev ntxuav kuj yog ib feem tseem ceeb ntawm kev saib xyuas. Hauv qee qhov kev siv, cov khoom siv graphite tuaj yeem khaws cov av, cov khib nyiab, lossis cov tshuaj lom neeg nyob rau lub sijhawm. Kev ntxuav cov khoom no siv cov txheej txheem tsim nyog tuaj yeem tshem tawm cov kab mob no thiab tiv thaiv lawv los ntawm kev ua kom xeb lossis lwm yam kev puas tsuaj. Piv txwv li, nyob rau hauv ib tug graphite pwm siv nyob rau hauv lub plastics kev lag luam, ntxuav cov pwm tom qab siv txhua yam tuaj yeem tiv thaiv kev tsim - li ntawm cov yas residues, uas tuaj yeem cuam tshuam rau saum npoo thiab kev ua haujlwm ntawm pwm.

Graphite Melting Crucibles
Graphite melting crucibles yog dav siv nyob rau hauv hlau melting thiab casting txheej txheem. Lub neej ntev ntawm graphite melting crucible tuaj yeem sib txawv nyob ntawm ntau yam. Hauv qhov chaw me me - qhov chaw ntsuas qhov chaw uas lub crucible yog siv rau qee zaus melting ntawm cov hlau me me ntawm qhov kub thiab txias, nws tuaj yeem kav ntev li ob peb lub hlis mus rau ib xyoos lossis ntau dua. Txawm li cas los xij, nyob rau hauv ib qho loj - scale industrial foundry qhov twg lub crucible yog siv tsis tu ncua ntawm kub kub rau melting loj ntim ntawm hlau, lub neej yuav raug txo mus rau ob peb lub lis piam los yog lub hlis.
Hom hlau raug melted kuj muaj feem xyuam rau lub neej ntawm lub crucible. Qee cov hlau, xws li txhuas, muaj qhov taw tes qis qis thiab tsis tshua muaj zog nrog graphite. Hauv qhov no, lub crucible yuav kav ntev dua. Ntawm qhov tod tes, cov hlau zoo li tooj liab lossis hlau, uas muaj cov ntsiab lus melting ntau dua thiab tuaj yeem ua rau ntau dua nrog graphite ntawm qhov kub thiab txias, tuaj yeem ua rau hnav lub crucible ntau dua.

Graphite Box Bowls
Graphite thawv tais feem ntau siv rau hauv daim ntawv thov xws li cov qauv npaj hauv chav kuaj lossis ua cov thawv rau me me - cov tshuaj tiv thaiv. Nyob rau hauv ib qho chaw zoo - khaws cia ib puag ncig, lub graphite thawv lub tais tuaj yeem kav ntev li ob peb xyoos. Txawm li cas los xij, yog tias nws siv nyob rau hauv ib puag ncig hnyav hnyav los yog raug tuav nruj, nws lub neej yuav raug txo kom tsawg. Piv txwv li, yog tias lub tais siv los tuav cov tshuaj corrosive heev yam tsis muaj kev tiv thaiv zoo, nws yuav pib corrode li ob peb lub hlis.
