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 zemveliso, i-coke yenaliti inokwahlulwa ibe luchungechunge lweoyile kunye nothotho lwamalahle eentlobo ezimbini zeenaliti ze-coke. Inaliti ye-coke eveliswe ngentsalela yepetroleum njengezinto ezikrwada luchungechunge lwenaliti yecoke. I-coke yenaliti yokulinganisa amalahle eveliswe kwitha yetha yamalahle kwaye iqhezu layo libizwa ngokuba yicoke yenaliti yokulinganisa amalahle.
Izalathi ezichaphazela umgangatho wenaliti ye-coke ziquka ubuninzi bokwenene, umxholo wesulfure, umxholo we-nitrogen, umxholo oguquguqukayo, umxholo we-ash, i-coefficient yokwandisa i-thermal, i-resistivity yombane, i-vibration-solid density, njl. yahlulwe ngokwebakala eliphezulu (ibakala eliphezulu), ibakala lokuqala nelesibini.
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 yenaliti yokulinganisa amalahle iyanda kwinkqubo ye-graphitization yobushushu obuphezulu, xa iqondo lokushisa lifikelela kwi-1500-2000 ℃, ngoko ke isantya sokunyuka kweqondo lokushisa kufuneka silawulwe ngokungqongqo, singafudumezi ngokukhawuleza, kungcono ukuba ungafaki. sebenzisa uthotho lwenkqubo yokuvelisa i-graphitization, i-coke yokulinganisa inaliti yamalahle ngokongeza izongezo zokulawula ukwandiswa kwayo, izinga lokwandiswa lingancitshiswa. Kodwa kunzima ngakumbi ukufezekisa ioli - i-coke yenaliti esekelwe.
6. I-oyile ye-calcined inomxholo omncinci we-coke kunye nobukhulu obuncinci bengqolowa, ngelixa inaliti yokulinganisa amalahle inomlinganiselo omncinci we-coke kunye nobukhulu obuziinkozo obukhulu (35-40 mm), obunokuhlangabezana nemfuneko yobungakanani bengqolowa yefomyula, kodwa izisa ubunzima. kukutyumza 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 abavelisa iinaliti ze-coke ziquka i-Shandong Jingyang, i-Shandong Yida, i-Jinzhou Petrochemical, i-Shandong Lianhua, i-Bora Biological, i-Weifang Fumei yamandla amatsha, i-Shandong Yiwei, i-Sinopec Jinling Petrochemical, i-Maoming Petrochemical, njl. inaliti coke yi Baowu Carbon Material, Baotailong Technology, Anshan Kaitan, Angang Chemical, Fang Daxi Kemo, Shanxi Hongte, Henan Kaitan, Xuyang Group, Zaozhuang Zhenxing, Ningxia Baichuan, Tangshan Dongri Amandla amatsha, Taiyuan Shengxu, njl.
