I-Needle coke luhlobo oluphezulu oluphuhliswe ngamandla kwizinto zekhabhoni. Inkangeleko yayo iqinile ene-porous kunye nesilivere engwevu kunye ne-metallic luster. Ulwakhiwo lwayo lunendlela ecacileyo yokuqukuqela, enemingxuma emikhulu kodwa embalwa kunye nokumila okumbhoxo kancinane. Yimpahla eluhlaza yokuvelisa iimveliso zekhabhoni eziphezulu ezifana ne-ultra-high power electrode, izinto ezikhethekileyo zekhabhoni, i-carbon fiber kunye nezinto zayo ezidibeneyo.
Ngokwezixhobo ezahlukeneyo zokuvelisa, i-coke yenaliti inokwahlulwa ibe luchungechunge lweoyile kunye nothotho lwamalahle eentlobo ezimbini zeenaliti ze-coke. I-coke yenaliti eveliswe ngentsalela yepetroleum njengento ekrwada luluhlu lwenaliti yecoke. I-coke yenaliti yokulinganisa amalahle eveliswe kwitha yetha yamalahle kwaye iqhezu layo libizwa ngokuba yicoke yenaliti yokulinganisa amalahle.
Izalathisi ezichaphazela umgangatho wenaliti ye-coke zibandakanya ubuninzi bokwenene, umxholo wesulfure, umxholo we-nitrogen, umxholo oguquguqukayo, umxholo womlotha, i-coefficient yokwandisa i-thermal, i-resistiveivity yombane, i-vibration-solid density, njl.
Umahluko wokusebenza phakathi kwenaliti yokulinganisa ilahle kunye ne-oyile yokulinganisa inaliti ye-coke iquka amanqaku alandelayo.
1. Phantsi kweemeko ezifanayo, i-electrode yegraphite eyenziwe nge-oil series inaliti ye-coke kulula ukuqulunqwa kunokuba i-coke yamalahle yenaliti ngokwemigaqo yokusebenza.
2. Emva kokuba iimveliso zegraphite zenziwe, iimveliso zegrafu ze-oyile yochungechunge lwenaliti i-coke inoxinaniso oluphezulu kancinane kunye namandla kunelo lamalahle ochungechunge lwenaliti ye-coke, ebangelwa kukwandiswa kwe-coke yamalahle yeenaliti ngexesha le-graphitization.
3. Ekusetyenzisweni okuthe ngqo kwe-electrode yegraphite, iimveliso zegrafu ezinenaliti yeoli zine-coefficient ephantsi yokwandiswa kwe-thermal.
4. Ngokubhekiselele kwizalathisi zomzimba kunye neekhemikhali ze-graphite electrode, ukuxhathisa okuthe ngqo kweemveliso ze-graphitized ze-oyile yochungechunge lwenaliti ye-coke iphezulu kancinane kuneemveliso zamalahle zeenaliti ze-coke.
5. Eyona nto ibaluleke kakhulu kukuba i-coke yokulinganisa amalahle iyanda kwinkqubo yokushisa okuphezulu kwe-graphitization, xa ubushushu bufikelela kwi-1500-2000 ℃, ngoko isantya sokunyuka kweqondo lokushisa kufuneka silawulwe ngokungqongqo, kungekhona ukufudumeza ngokukhawuleza, kungcono ukuba ungasebenzisi uchungechunge lwenkqubo yokuvelisa i-graphitization, i-coke yokulinganisa i-coke yokulinganisa amalahle ngokudibanisa i-additives yokunciphisa isantya sokwandisa, ukulawula izinga lokwandiswa. Kodwa kunzima ngakumbi ukufezekisa ioli - i-coke yenaliti esekelwe.
6. Inkqubo yeoli ye-calcined inomxholo omncinci we-coke kunye nobukhulu bengqolowa obuncinci, ngelixa inaliti yokulinganisa amalahle inomlinganiselo omncinci we-coke kunye nobukhulu obuziinkozo obukhulu (35-40 mm), obunokuhlangabezana nemfuneko yobungakanani bengqolowa yefomyula, kodwa izisa ubunzima ekutyunjweni komsebenzisi.
7. Ngokutsho kweJapan Petroleum Coke Company, kucatshangelwa ukuba ukubunjwa kwe-oil series inaliti i-coke ilula kunokuba i-coke ye-coal series coke, ngoko kulula ukulawula ngexesha lokupheka.
Ukusuka kule mbono ingasentla, inkqubo yeoli inaliti coke ine ephantsi ezine: ubunzima obuthile obuphantsi, amandla aphantsi, i-CTE ephantsi, ukuxhathisa okuphantsi, ezimbini zokuqala eziphantsi kwiimveliso zegraphite, ezimbini zokugqibela eziphantsi kwiimveliso zegraphite ziyathandeka. Ngokubanzi, izalathisi zokusebenza zothotho lweenaliti ze-oyile zingcono kunezo zothotho lweenaliti ze-coke, kwaye imfuno yesicelo ingaphezulu.
Okwangoku, i-electrode yegraphite yeyona marike iphambili yemfuno yenaliti ye-coke, ibalwa malunga ne-60% yosetyenziso lulonke lwenaliti ye-coke, kwaye amashishini e-electrode anemfuno ecacileyo yomgangatho yenaliti ye-coke, ngaphandle kwemfuno yomgangatho wenaliti. I-lithium ion ibhetri ye-anode izixhobo zinemfuno eyohlukeneyo ye-coke yenaliti, imarike yedijithali ephezulu ikhetha i-oyile ephekiweyo ye-coke, imarike yebhetri yamandla ixhomekeke ngakumbi kwi-coke eluhlaza engabizi kakhulu.
Ukuveliswa kwenaliti ye-coke kunomda othile wobugcisa, ngoko ke kukho amashishini ambalwa asekhaya. Okwangoku, abavelisi be-oyile basekhaya abaqhelekileyo abavelisi benaliti ye-coke baquka i-Shandong Jingyang, i-Shandong Yida, i-Jinzhou Petrochemical, i-Shandong Lianhua, i-Bora Biological, i-Weifang Fumei Amandla amatsha, i-Shandong Yiwei, i-Sinopec Jinling Petrochemical, i-Maoming Petrochemical, njl. Angang Chemical, Fang Daxi Kemo, Shanxi Hongte, Henan Kaitan, Xuyang Group, Zaozhuang Zhenxing, Ningxia Baichuan, Tangshan Dongri Amandla amatsha, Taiyuan Shengxu, njl.
