Musiyano Wakakosha Pakati peGraphitized Petroleum Coke neOrdinary Petroleum Coke

1. Maumbirwo eAtomu: Kuchinja kweHunhu kubva paKusagadzikana kuenda paKurongeka

• Coke yePetroleum Yakajairika: Maatomu ekabhoni akarongwa muchimiro chisina kurongeka kana kuti chepfupi, chakafanana nechimiro chekabhoni isina chimiro. Ine zvikanganiso zvakawanda zve lattice, izvo zvinoganhurira kufambisa kwayo magetsi, kufambisa kwekupisa, uye kugadzikana kwemakemikari.
• Graphitized Petroleum Coke: Mushure mekugadzirisa graphitization patembiricha yepamusoro inosvika 3000°C, maatomu ekabhoni anorongwazve kuita chimiro chegraphite chine hexagonal layered. Chimiro ichi chine lattice integrity yakakura, simba repakati pezvikamu zvisina simba, uye resistance yakaderera yekufamba kwemaerekitironi. Kuchinja uku kwechimiro kunoita kuti ive nezviratidzo zvegrafiti zvakajairika, zvakaita semagetsi akakwira, kupisa kwakanyanya, uye kugadzikana kwemakemikari kwakanaka.

2. Kusiyana Kwemashandiro: Maumbirwo Anoona Mashandiro

Kufambisa Kwemagetsi uye Kupisa

• Graphitized Petroleum Coke: Kugona kwayo kusimba kwakaderera zvakanyanya pane kwepetroleum coke yakajairika (inogona kunge yakaderera kusvika pasi pe0.001 Ω·m), uye thermal conductivity yayo yakakwira kakawanda. Yakakodzera mamiriro ezvinhu ane zvinodiwa zvakasimba pamagetsi nethermal conductivity (semuenzaniso, zvinhu zveanode zvemabhatiri e lithium-ion, ma graphite electrodes ane simba guru).
• Ordinary Petroleum Coke: Nekuda kwekusashanda zvakanaka kwemuumbi wayo, haina simba rekufambisa magetsi uye inonyanya kushandiswa munzvimbo dzine zvinodiwa zvishoma (semuenzaniso, mafuta, zvinhu zvekabhoni zvakajairika).

Kugadzikana kweMakemikari

• Graphitized Petroleum Coke: Maumbirwo ayo anowedzera kuramba kwayo ngura kubva kumaacids, alkalis, nezvimwewo. Haikurumidzi kuoxidation uye kuora kana tembiricha yakakwira, zvichikonzera hupenyu hwayo hwekushanda hwakareba.
• Ordinary Petroleum Coke: Inowanzo kuvadzwa kana kuchipisa zvakanyanya kana kuti kuchipisa, zvichiita kuti mashandiro aishande nekukurumidza.

Zviri Mukati meKusachena

• Graphitized Petroleum Coke: Maitiro e graphitization anogona kuderedza zvakanyanya huwandu hwetsvina dzakadai sesarufa nenitrogen (huwandu hwesarufa hunogona kuderedzwa kusvika pasi pe0.1%), zvichideredza kusvibiswa uye migumisiro yakaipa panguva yekunyungudutsa (semuenzaniso, maburi nemaburi mu castings).
• Ordinary Petroleum Coke: Ine huwandu hwakawanda hwekusachena uye inoda kurapwa kwekutanga (semuenzaniso, calcination) kuti ienderane nezvinodiwa nemamwe maindasitiri.

3. Minda Yekushandisa: Kusiyana Kwekushanda Kunosimudzira Kusiyanisa Kwekuda

Graphitized Petroleum Coke

• Metallurgy yepamusoro-soro: Semuchina wecarburizer, unogona kuwedzera kabhoni yesimbi yakanyungudutswa zvinobudirira uye kuvandudza hunhu hwesimbi (semuenzaniso, simba, kuomarara), ukuwo uchideredza kuiswa kwezvinhu zvinokuvadza zvakaita sesarufa nenitrogen.
• Zvinhu Zvitsva zveSimba: Chinhu chakakosha pakugadzira zvinhu zve anode zvemabhatiri e lithium-ion. Kufambiswa kwayo kwemagetsi kwakakwirira uye chimiro chayo chakaiswa muzvikamu zvinobatsira kuvandudza kushanda kwechaji nekuburitsa simba uye hupenyu hwemabhatiri.
• Zvigadzirwa zveCarbon Zvakakosha: Zvinoshandiswa mukugadzira mabhuroko makuru e cathode, ma electrodes ane graphitized, nezvimwewo, zvichienderana nekuchena kwayo kwakanyanya, crystallinity yakanyanya, uye kuramba kupisa kwakanyanya.

Coke yePetroleum yakajairika

• Nzvimbo yemafuta: Coke ine sarufa yakawanda inowanzoshandiswa mumafekitori esimende, mafekitori egirazi, mafekitori emagetsi, nezvimwewo, semafuta anodhura zvishoma.
• Zvinhu Zvikuru zveKabhoni: Koke ine sarufa shoma, mushure mekuchekwa kwesimbi, inogona kushandiswa mukugadzira maanode e aluminium electrolysis, ma electrode e graphite akajairwa, nezvimwewo, asi mashandiro ayo haana kunaka pane ezvigadzirwa zve graphitized.

4. Maitiro Ekugadzira: Kuchinjana Pakati Pekupisa Nemutengo

• Coke yemafuta yakajairika: Inogadzirwa kuburikidza nekunonoka kubikwa kana kubikwa kwemvura, nemitengo yakaderera. Zvisinei, inoda kuwedzera calcination (inenge 1300°C) kubvisa zvinhu zvinoshanduka uye hunyoro, nokudaro zvichiwedzera huwandu hwekabhoni hwakagadzika.
• Graphitized Petroleum Coke: Ichishandisa petroleum coke yakajairika sezvinhu zvakabikwa, inoda kurapwa kwe graphitization yepamusoro-soro pa3000°C. Izvi zvinowedzera zvakanyanya kushandiswa kwesimba uye mitengo yemidziyo, asi chigadzirwa ichi chine kukosha kwakawedzerwa.

Mhedziso: Kusiyana Kwakakosha uye Pfungwa dzeSarudzo
