Sei paine musiyano mukuru mukushanda kwavo kana vese vachibva ku petroleum coke? Chii chaizvo chakachinja mashiripiti e "graphitization" pa3000℃?

Kugadziriswa kwegirafiti, kuburikidza nekupisa kwakanyanya pa3000℃, kunoshandura maatomu ekabhoni ari mupetroleum coke kubva muchimiro chisina kurongeka kuita chimiro chegirafiti chakarongeka zvakanyanya, zvichiwedzera zvakanyanya kufambiswa kwemagetsi, kufambiswa kwemafuta, kuderedza kuramba kwemagetsi uye huwandu hwedota, ukuwo zvichivandudzawo hunhu hwemakanika uye kugadzikana kwemakemikari. Izvi zvinoguma nemusiyano mukuru wekushanda pakati pegirafiti yepetroleum coke negirafiti yepetroleum coke yakajairika. Ongororo yakadzama ndeiyi inotevera:

1. Kugadziriswazve kweZvivako Zvidiki: Kubva paKusagadzikana kuenda paKurongeka

Coke yepetroleum yakajairika: Inogadzirwa nekunonoka kubikwa kwezvisaririra zvepetroleum, maatomu ayo ekabhoni akarongwa nenzira isina kurongeka, ine zvikanganiso zvakawanda uye tsvina, zvichiita chimiro chakafanana ne "kusarongeka kwezvikamu zvema "layer stacking". Chimiro ichi chinokanganisa kufamba kwemaerekitironi uye chinoderedza kushanda zvakanaka kwekupisa, nepo tsvina (yakadai sesarufa nemadota) ichikanganisa mashandiro.
Graphitized Petroleum Coke: Mushure mekugadziriswa kwekupisa kwakanyanya pa3000℃, maatomu ekabhoni anopararira uye anorongwazve kuburikidza nekupisa, zvichigadzira chimiro chakafanana negraphite. Muchimiro ichi, maatomu ekabhoni akarongwa mugridi ine hexagonal, ine zvikamu zvakabatana pamwe chete nemasimba evan der Waals, zvichigadzira kristaro yakarongerwa zvakanyanya. Kuchinja uku kwakafanana ne "kuronga mapepa akapararira kuita mabhuku akajeka," zvichiita kuti maerekitironi nekupisa zvishande zvakanaka.

2. Nzira Huru dzeKuvandudza Mashandiro

Kufambiswa Kwemagetsi: Kusasimba kwemagetsi kwe graphitized petroleum coke kunoderera zvakanyanya, uye conductivity yayo inodarika iyo ye coke yemafuta yakajairika. Izvi zvinodaro nekuti chimiro chakarongeka chinoderedza kupararira kwemaerekitironi, zvichiita kuti maerekitironi afambe zvakasununguka. Semuenzaniso, muzvinhu zvemagetsi ebhatiri, graphitized petroleum coke inogona kupa simba rakasimba remagetsi.
Kufambiswa Kwemhepo Nekupisa: Maatomu ekabhoni akarongeka zvakanaka muchimiro chakarongwa anobatsira kutamisa kupisa nekukurumidza kuburikidza nekudengenyeka kwelattice. Izvi zvinoita kuti graphitized petroleum coke ive yakanaka kushandiswa muzvinhu zvinopisa kupisa, zvakaita sema heat sinks ezvikamu zvemagetsi.
Hunhu hweMichina: Maumbirwo egirazi epetroleum coke ane graphitized anoita kuti ive yakaoma uye irambe ichikura, ukuwo ichiramba ichichinjika, zvichiita kuti isanyanya kutyoka.
Kugadzikana Kwemakemikari: Kurapa nekupisa kwakanyanya kunobvisa tsvina yakawanda (yakadai sesarufa nemadota), kuderedza huwandu hwenzvimbo dzinoshanda dzemakemikari uye kuita kuti petroleum coke ine graphitized ive yakasimba munzvimbo dzine ngura.

3. Kusarudzwa kwakasiyana kweZviitiko zveKushandisa

Ordinary Petroleum Coke: Nekuda kwemutengo wayo wakaderera, inowanzoshandiswa munzvimbo dzisina zvinodiwa zvakanyanya pakushanda, zvakaita semafuta, zvinhu zvekuvaka migwagwa, kana sezvinhu zvekugadzirisa graphitization.
Graphitized Petroleum Coke: Nekuda kwekushanda kwayo kwemagetsi kwepamusoro-soro, kufambisa kwekupisa, uye kugadzikana kwemakemikari, inoshandiswa zvakanyanya muminda yepamusoro-soro:

• MaElectrode eBhatiri: Sechinhu chisina kunaka cheelectrode, inowedzera kushanda zvakanaka kwekuchaja nekuburitsa charging uye hupenyu hwemabhatiri.
• Indasitiri yesimbi: Semuchina wekaburiza, unogadzirisa huwandu hwekabhoni musimbi yakanyungudutswa uye unovandudza hunhu hwesimbi.
• Kugadzira Semiconductor: Inoshandiswa kugadzira zvigadzirwa zvegrafiti zvine hutsanana hwakanyanya, zvichizadzisa zvinodiwa zvemichina yakanyatsogadzirwa.
• Mudenga: Inoshanda semudziyo wekudzivirira kupisa, inotsungirira mamiriro ekunze anopisa zvakanyanya.

4. Mabasa Akakosha eGraphitization Process

Kudzora Tembiricha: 3000℃ ndiyo chiyero chakakosha chekupisa kwegraphitization. Pasi petembiricha iyi, maatomu ekabhoni haagone kurongazve zvizere, zvichikonzera kusakwana kwegraphitization degree; pamusoro petembiricha iyi, kupisa kwakanyanya kwezvinhu kunogona kuitika, zvichikanganisa mashandiro.
Kudzivirirwa Kwemhepo: Maitiro aya anowanzoitwa mumhepo isina simba, senge argon kana nitrogen, kudzivirira maatomu ekabhoni kuti asapindirane neokisijeni kuti aumbe kabhoni dioxide, izvo zvinozoita kuti zvinhu zvirasikirwe.
Nguva uye Zvinokonzera: Kuwedzera nguva yekubata kana kuwedzera zvinokonzeresa (senge boron kana titanium) kunogona kukurumidzisa maitiro ekugadzira graphitization, asi zvinowedzera mitengo.
