I-needle coke iyinhlobonhlobo yekhwalithi ephezulu eyakhiwe ngamandla ezintweni zekhabhoni.Ukubukeka kwayo kuyi-porous solid nesiliva grey kanye ne-metallic luster.Isakhiwo sayo sinokuthungwa okugelezayo okusobala, okunezimbobo ezinkulu kodwa ezimbalwa kanye nokuma okusaqanda okuthe ukuqanda.Yimpahla eluhlaza yokukhiqiza imikhiqizo yekhabhoni ephezulu efana ne-ultra-high power electrode, i-carbon material ekhethekile, i-carbon fiber kanye nezinto zayo eziyinhlanganisela.
Ngokwezinto zokusetshenziswa ezihlukene, i-coke yenaliti ingahlukaniswa ibe yi-coke yenaliti yamafutha kanye ne-coke yenaliti yamalahle.I-needle coke ekhiqizwa kuzinsalela ze-petroleum i-coke yenaliti yamafutha.I-coke yenaliti ekhiqizwe nge-coal tar pitch kanye nengxenye yayo iwuchungechunge lwamalahle yenaliti coke.
Izinkomba ezithinta ikhwalithi yenaliti ye-coke zihlanganisa ukuminyana kweqiniso, okuqukethwe kwesibabule, okuqukethwe kwe-nitrogen, izinto ezishintshashintshayo, okuqukethwe komlotha, i-coefficient yokwandisa ukushisa okushisayo, ukumelana nokuqina, ukudlidliza, njll. Ngenxa ye-coefficient yenkomba ethize ehlukene, i-coke yenaliti ingahlukaniswa Ibanga eliphezulu (ibanga elihle kakhulu), ibanga lokuqala kanye nelesibili.
Umehluko wokusebenza phakathi kwe-coke yenaliti yamalahle ne-oyela uhlanganisa amaphuzu alandelayo.
1. Ngaphansi kwezimo ezifanayo, i-electrode ye-graphite eyenziwe nge-coke yenaliti yamafutha kulula ukubumba kune-coke yenaliti yamalahle.
2. Ngemva kokwenza imikhiqizo ye-graphite, ukuminyana namandla emikhiqizo ye-graphitized ye-oil-series inaliti ye-coke iphakeme kancane kune-coke yenaliti yochungechunge lwamalahle, okubangelwa ukunwetshwa kwe-coke yenaliti yochungechunge lwamalahle ngesikhathi se-graphitization.
3. Ekusetshenzisweni okukhethekile kwe-graphite electrode, umkhiqizo owenziwe nge-graphiti we-coke yenaliti yamafutha une-coefficient ephansi yokwandisa okushisayo.
4. Ngokwezinkomba zomzimba namakhemikhali we-graphite electrode, ukumelana okuthile komkhiqizo we-graphitized we-coke yenaliti yamafutha kuphakeme kancane kunomkhiqizo we-coke yenaliti yamalahle.
5. Okubaluleke kakhulu ukuthi i-coke yenaliti yesilinganiso samalahle iyanda lapho izinga lokushisa lifinyelela ku-1500-2000 ℃ ngenqubo yokushisa okuphezulu kwe-graphitization, ngakho izinga lokushisa lokushisa kufanele lilawulwe ngokuqinile, hhayi ukukhuphuka kwezinga lokushisa, kungcono ukungasebenzisi uchungechunge lwenqubo yokukhiqiza i-graphitization, i-coke yenaliti yokulinganisa amalahle ngokungeza izithasiselo zokulawula ukunwetshwa kwayo, izinga lokunwetshwa lingancishiswa.Kodwa kunzima kakhulu ukufeza inaliti yenaliti ye-coke.
6. I-coke yenaliti kawoyela e-calcined ine-coke encane kakhulu kanye nosayizi wezinhlayiyana ezinhle, kuyilapho inaliti ye-coke yamalahle inokuqukethwe okuncane nosayizi wezinhlayiyana ezinkulu (35 — 40 mm), ezingahlangabezana nezidingo zosayizi wezinhlayiyana zefomula, kodwa iletha ubunzima kubasebenzisi.
7. Ngokusho kokwethulwa kwe-Japan Petroleum Coke Company, kukholelwa ukuthi ukwakheka kwe-coke yenaliti yamafutha kulula kune-coke yenaliti yamalahle, ngakho-ke kulula ukulawula isikhathi sokupheka nokushisa.
Kusukela ngenhla, inaliti yenaliti ye-coke inezine eziphansi: amandla adonsela phansi amanga aphansi, amandla aphansi, i-CTE ephansi, ukumelana okuqondile okuphansi, okubili kokuqala okuphansi kwemikhiqizo ye-graphite, okubili kokugcina okuphansi kwemikhiqizo ye-graphite kuyathandeka.Sekukonke, izinkomba zokusebenza zochungechunge lwenaliti ye-oyela zingcono kune-coke yenaliti yochungechunge lwamalahle, futhi isidingo sohlelo lokusebenza singaphezulu.
Njengamanje, i-graphite electrode iyimakethe efunwa kakhulu ye-coke yenaliti, ibalwa cishe ngama-60% okusetshenziswa okuphelele kwe-coke yenaliti, kanti amabhizinisi ama-electrode anesidingo esicacile sekhwalithi ye-coke yenaliti, ngaphandle kwesidingo sekhwalithi yomuntu siqu.Isidingo senaliti se-coke se-lithium ion battery anode material sihluke kakhulu, imakethe yedijithali ephezulu ithanda i-coke ephekwe ngamafutha, imakethe yebhethri yamandla incike kakhulu ku-coke ngokusebenza kwezindleko eziphezulu.
Ukukhiqizwa kwe-needle coke kunomkhawulo othile wezobuchwepheshe, ngakho-ke amabhizinisi asekhaya awavamile.Njengamanje, amabhizinisi ajwayelekile afuywayo okukhiqizwa kwenaliti kawoyela ahlanganisa: Weifang Fumei new Energy, Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei amandla amasha, Shandong Yiwei, Sinopec jinling Petrochemical, Maoming petrochemical, njll. . Uchungechunge lwamalahle enaliti ye-coke eyinhloko amabhizinisi okukhiqiza i-Baowu carbon material, ubuchwepheshe be-Baotailong, i-Anshan evulekile ye-carbon, i-Anshan Chemical, i-Fang Daxi ke Mo, i-Shanxi Macro, i-Henan evulekile ye-carbon, i-Xuyang Group, ukuvuselelwa kwe-Zaozhuang, i-Ningxia Baichuan, i-Tangshan Dongri entsha yamandla, i-Taiyuan Shengxu njalo njalo.
