Hav nyob ntawd! Kuv yog tus xa khoom ntawm graphite ingots, thiab kuv feem ntau tau nug txog yuav ua li cas los ntsuas qhov zoo ntawm cov kev xav me me no. Graphite ingots yog ib qho tseem ceeb heev nyob rau hauv ib pawg ntawm kev lag luam, los ntawm hlau smelting mus rau electronics. Yog li, tau txais qhov zoo yog qhov loj. Cia peb dhia mus rau hauv txoj kev sib txawv peb tuaj yeem kuaj xyuas qhov zoo ntawm graphite ingot.
Kev tshuaj xyuas lub cev
Thawj kauj ruam hauv kev sim graphite ingot yog qhov qub zoo - kev tshuaj xyuas lub cev. Qhov no zoo li muab nws ib zaug - dhau ntawm koj tus kheej ob lub qhov muag thiab txhais tes.
Qhov tshwm sim: Ua tib zoo saib ntawm qhov chaw ntawm lub ingot. Nws yuav tsum tau du, tsis muaj cov kab nrib pleb, qhov, lossis lwm yam tsis xws luag. Ib qho ntxhib lossis puas nto tuaj yeem qhia tau tias muaj teeb meem thaum lub sijhawm tsim khoom. Piv txwv li, yog tias muaj cov kab nrib pleb loj, nws tuaj yeem txhais tau tias lub ingot tsis txias kom zoo, uas tuaj yeem cuam tshuam rau nws lub zog thiab kev ua haujlwm.
Loj thiab Zoo: Xyuas kom lub ingot ua tau raws li qhov ntev. Txhua qhov sib txawv ntawm tus qauv loj tuaj yeem ua rau muaj teeb meem thaum nws siv hauv cov ntawv thov. Piv txwv li, yog tias nws loj dhau lossis me dhau rau cov khoom siv graphite xws li Graphite Tube, nws yuav tsis haum.
Kev ntsuas ceev
Qhov ceev yog qhov tseem ceeb hauv kev txiav txim siab qhov zoo ntawm graphite ingot. Nws muab peb lub tswv yim ntawm yuav ua li cas nruj nreem ntim cov graphite hais.
Kev ntsuas ntsuas: Peb feem ntau siv Archimedes 'txoj cai los ntsuas qhov ceev. Ua ntej, peb ntsuas lub ingot nyob rau hauv cov huab cua. Tom qab ntawd, peb muab tso rau hauv dej (feem ntau yog dej) thiab ntsuas nws qhov hnyav. Los ntawm kev siv ob qhov hnyav thiab qhov ntom ntawm cov kua, peb tuaj yeem xam qhov ntom ntawm cov ingot.
Dab tsi Ceev Qhia Peb: Qhov ceev dua feem ntau txhais tau tias zoo dua. Nws qhia tau hais tias cov graphite muaj tsawg qhov pores thiab cov qauv zoo sib xws. Qhov no yog ib qho tseem ceeb vim hais tias ib tug denser ingot yuav muaj zog thiab ntau resistant rau hnav thiab tsim kua muag. Piv txwv li, nyob rau hauv Graphite Crucible, ib tug denser graphite ingot yuav muaj peev xwm tiv taus qhov kub thiab txias thiab tshuaj tiv thaiv zoo dua.
Kev Xeem Hardness
Hardness yog lwm qhov tseem ceeb ntawm graphite ingot zoo. Nws cuam tshuam zoo npaum li cas lub ingot tuaj yeem tiv thaiv khawb, puas, thiab deformation.
Cov txheej txheem kuaj: Muaj ob peb txoj hauv kev los ntsuas qhov hardness ntawm graphite ingot. Ib txoj hauv kev yog Rockwell hardness test. Hauv qhov kev sim no, ib qho me me indenter yog nias rau hauv qhov chaw ntawm lub ingot nrog lub zog tshwj xeeb, thiab qhov tob ntawm qhov indentation yog ntsuas. Lwm txoj kev yog Brinell hardness test, uas siv lub indenter loj dua thiab ntsuas lub cheeb ntawm indentation.
Qhov tseem ceeb ntawm Hardness: Ib qho nyuaj graphite ingot yog ntau ruaj. Nws tuaj yeem siv rau hauv cov ntawv thov uas nws yuav raug rau ntau yam kev ntxhov siab. Piv txwv li, yog tias lub ingot yuav raug siv los ua cov khoom siv rau cov tshuab, lub hardness siab dua yuav ua kom cov khoom siv ntev dua thiab ua tau zoo dua.
Thermal Conductivity Test
Graphite paub txog nws cov thermal conductivity zoo heev, thiab cov cuab yeej no yog qhov tseem ceeb hauv ntau daim ntawv thov.
Kev xeem: Txhawm rau ntsuas qhov thermal conductivity ntawm graphite ingot, peb siv cov cuab yeej tshwj xeeb hu ua thermal conductivity meter. Lub 'meter' ntsuas tus nqi ntawm cov cua sov kis los ntawm lub ingot.
Vim Li Cas Nws Tseem Ceeb: Zoo thermal conductivity yog ib qho tseem ceeb hauv kev siv xws li hlau smelting. Hauv Graphite Tube siv rau hauv cov hlau smelting, siab thermal conductivity tso cai rau kev hloov pauv kom zoo, uas pab ua kom cov hlau yaj sai thiab sib npaug.
Tshuaj ntsuam xyuas
Cov tshuaj muaj pes tsawg leeg ntawm graphite ingot tuaj yeem muaj kev cuam tshuam loj rau nws qhov zoo thiab kev ua haujlwm.
Txoj kev tsom xam: Peb siv cov txheej txheem zoo li spectroscopy los soj ntsuam cov tshuaj muaj nyob hauv cov khoom siv. Qhov no tuaj yeem qhia peb yog tias muaj cov impurities lossis yog cov graphite muaj qhov sib piv ntawm carbon thiab lwm yam khoom.
Kev cuam tshuam ntawm cov tshuaj lom neeg: Cov impurities tuaj yeem ua rau lub cev tsis muaj zog thiab cuam tshuam rau nws cov khoom. Piv txwv li, yog tias muaj ntau cov hlau tsis huv, nws tuaj yeem txo cov hluav taws xob conductivity ntawm graphite. Ntawm qhov tod tes, ib qho tshuaj muaj pes tsawg leeg kom ntseeg tau tias lub ingot muaj cov khoom xav tau rau nws daim ntawv thov.
Kev ntsuas hluav taws xob conductivity
Graphite kuj yog ib qho khoom siv hluav taws xob zoo, thiab cov cuab yeej no tseem ceeb hauv ntau qhov kev lag luam, tshwj xeeb tshaj yog cov khoom siv hluav taws xob.
Txoj Kev Xeem: Peb siv lub voj voog yooj yim los ntsuas qhov hluav taws xob conductivity ntawm lub ingot. Los ntawm kev siv ib qho hluav taws xob hla lub ingot thiab ntsuas qhov tam sim no, peb tuaj yeem suav nws qhov tsis kam thiab tom qab ntawd txiav txim siab qhov conductivity.
Qhov tseem ceeb hauv kev siv: Hauv cov khoom siv hluav taws xob, graphite ingot nrog cov hluav taws xob hluav taws xob siab tuaj yeem siv los ua cov khoom xws li electrodes. Nws tso cai rau kom muaj txiaj ntsig zoo ntawm hluav taws xob, uas yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov cuab yeej.
Oxidation Resistance Test
Graphite tuaj yeem oxidize thaum raug kub thiab oxygen. Kev ntsuas nws cov oxidation tsis kam yog qhov tseem ceeb los xyuas kom meej tias nws ua haujlwm ntev -.
Cov txheej txheem kuaj: Peb sov lub ingot nyob rau hauv ib qho oxygen - nplua nuj ib puag ncig thiab ntsuas qhov poob phaus nyob rau hauv ib lub sij hawm. Qhov poob phaus qhia tau zoo dua oxidation tsis kam.
Qhov cuam tshuam hauv kev siv: Hauv cov ntawv thov uas cov graphite ingot yuav raug kub thiab oxygen, xws li hauv qee cov hlau - cov txheej txheem smelting, zoo oxidation kuj tseem ceeb. Nws xyuas kom meej tias lub ingot tsis tawg sai sai thiab tuaj yeem siv tau ntev dua.
Kev kuaj porosity
Porosity yog hais txog qhov chaw lossis qhov pores hauv graphite ingot.
Txoj Kev Xeem: Muaj ntau txoj hauv kev los ntsuas qhov porosity, xws li mercury intrusion porosimetry. Nyob rau hauv txoj kev no, mercury raug yuam mus rau hauv lub pores ntawm lub ingot nyob rau hauv siab, thiab lub ntim ntawm mercury absorbed yog ntsuas.
Qhov cuam tshuam rau Kev Ua Zoo: Cov porosity siab tuaj yeem ua rau lub ingot tsis muaj zog thiab txo nws qhov ntom thiab lwm yam khoom. Nws tseem tuaj yeem ua rau lub ingot muaj kev cuam tshuam rau cov tshuaj tua kab mob. Piv txwv li, nyob rau hauv ib tug Graphite Crucible, siab porosity tuaj yeem ua rau nkag mus rau cov hlau molten rau hauv lub qhov hws, uas tuaj yeem ua rau lub crucible puas.
Yog li ntawd, koj muaj nws! Nov yog txoj hauv kev tseem ceeb uas peb ntsuas qhov zoo ntawm graphite ingot. Raws li tus neeg xa khoom, kuv paub tseeb tias tag nrho peb cov khoom siv tau dhau los ntawm cov kev xeem nruj no kom ntseeg tau tias lawv ua tau raws li cov qauv siab tshaj plaws. Yog tias koj nyob hauv kev ua lag luam rau siab - zoo graphite ingots, kuv xav nrog koj tham. Txawm hais tias koj xav tau lawv los ua Graphite Tubes, Graphite Crucibles, lossis lwm yam khoom, peb tau txais koj them. Hu rau kuv yog tias koj xav tham txog koj cov kev xav tau thiab tau txais qhov zoo tshaj plaws graphite ingots rau koj lub lag luam.
