I-Needle coke luhlobo oluphezulu oluphezulu oluphuhliswe ngamandla kwizinto zekhabhoni. Inkangeleko yayo iqinile ene-porous kunye nesilivere engwevu kunye ne-metallic luster. Ulwakhiwo lwalo lunokwakheka okuhambayo okucacileyo, kunye nemingxuma emikhulu kodwa embalwa kunye nokumila okumbhoxo kancinane. Yimpahla eluhlaza yokuvelisa iimveliso zekhabhoni eziphezulu ezifana ne-electrode ye-ultra-high, i-carbon material ekhethekileyo, i-carbon fiber kunye nezinto zayo ezidibeneyo.
Ngokwezixhobo ezahlukeneyo eziluhlaza, inaliti ye-coke inokwahlulwa ibe yi-oyile yenaliti ye-coke kunye ne-coke yenaliti yamalahle. Inaliti coke eveliswe kwintsalela yepetroleum yi-oyile yenaliti coke. I-coke yenaliti eveliswa kwi-tar pitch yamalahle kwaye iqhezu layo lichungechunge lwenaliti ye-coke.
Izalathi ezichaphazela umgangatho wenaliti ye-coke ziquka ubuninzi bokwenene, umxholo wesulfure, umxholo we-nitrogen, into eguqukayo, umxholo wothuthu, i-coefficient yokwandisa i-thermal, i-resistivity, i-vibration density, njl. ibakala eliphezulu (ibakala eligqwesileyo), ibanga lokuqala nelesibini.
Umahluko wokusebenza phakathi kwamalahle kunye neoli yenaliti ye-coke iquka la manqaku alandelayo.
1. Ngaphantsi kweemeko ezifanayo, i-electrode yegraphite eyenziwe nge-oyile inaliti ye-coke ilula ukumila kune-coke yenaliti yamalahle.
2. Emva kokwenza iimveliso zegraphite, ubuninzi kunye namandla emveliso ye-graphitized ye-oil-series inaliti ye-coke iphezulu kancinane kune-coke ye-coal-series coke coke, ebangelwa ukwanda kwe-coke ye-coal-series ye-coke ngexesha le-graphitization.
3. Ekusetyenzisweni okukhethekileyo kwe-graphite electrode, imveliso ye-graphitize ye-oyile yenaliti ye-coke ine-coefficient ephantsi yokwandiswa kwe-thermal.
4. Ngokubhekiselele kwizalathisi zomzimba kunye neekhemikhali ze-graphite electrode, ukuchasana okuthe ngqo kwemveliso ye-graphitized ye-oyile inaliti ye-coke iphezulu kancinane kunemveliso ye-coke ye-coke.
5. Okubaluleke kakhulu kukuba i-coke yokulinganisa i-coke iyanda xa ubushushu bufikelela kwi-1500-2000 ℃ kwinkqubo ye-graphitization yobushushu obuphezulu, ngoko ke izinga lokunyuka kweqondo lokushisa kufuneka lilawulwe ngokungqongqo, kungekhona ukunyuka kobushushu ngokukhawuleza, kungcono ukuba ungasebenzisi. series graphitization inkqubo imveliso, ukulinganisa amalahle inaliti coke ngokongeza izongezo ukulawula ukwandiswa kwayo, izinga ukwandiswa kungancitshiswa. Kodwa kunzima ngakumbi ukufezekisa inaliti ye-oyile ye-coke.
6. Ioli ye-calcined yenaliti ye-coke ine-coke encinci kunye ne-particle encinci ye-particle size, ngelixa i-coke ye-coke ye-naliti inomxholo omncinci kunye nobukhulu be-particle enkulu (35 - 40 mm), enokuthi ihlangabezane neemfuno ze-particle ye-particle size, kodwa izisa ubunzima kubasebenzisi.
7. Ngokutsho kokuqaliswa kweJapan Petroleum Coke Company, kukholelwa ukuba ukubunjwa kweoli ye-oil coke kulula kune-coke inaliti yamalahle, ngoko kulula ukulawula ixesha lokupheka kunye nokufudumala.
Ukusuka apha ngasentla, inaliti ye-oyile i-coke ine-4 ephantsi: umxhuzulane ophantsi wobuxoki, amandla aphantsi, i-CTE ephantsi, ukuxhathisa okuphantsi, ezimbini zokuqala eziphantsi ukuya kwiimveliso zegraphite, ezimbini zokugqibela eziphantsi ukuya kwiimveliso zegraphite zilungile. Ngokubanzi, izalathisi zokusebenza ze-oyile yeenaliti ze-coke zingcono kunothotho lwenaliti ye-coke, kwaye imfuno yesicelo nayo ingaphezulu.
Okwangoku, i-electrode yegraphite yeyona ndawo ifunwayo yintengiso yenaliti ye-coke, ibalwa malunga ne-60% yosetyenziso lulonke lwenaliti ye-coke, ngelixa amashishini e-electrode anemfuno ecacileyo yomgangatho wenaliti ye-coke, ngaphandle kwemfuno yekhwalithi yomntu. Imfuno yenaliti ye-coke ye-lithium ion ibhetri ye-anode yezinto yahluke kakhulu, imarike yedijithali ephezulu ithanda i-oyile ephekiweyo ye-coke, imarike yebhetri yamandla ixhomekeke ngakumbi kwi-coke kunye nokusebenza kweendleko eziphezulu.
Ukuveliswa kweenaliti ze-coke kunomda othile wobugcisa, ngoko ke amashishini asekhaya anqabile. Okwangoku, amashishini aqhelekileyo asekhaya emveliso ye-oyile inaliti ibandakanya: Weifang Fumei Amandla amatsha, Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei amandla amatsha, Shandong Yiwei, Sinopec jinling Petrochemical, Maoming petrochemical, njl. . Amalahle series inaliti coke amashishini emveliso eqhelekileyo Baowu carbon, iteknoloji Baotailong, Anshan evulekileyo carbon, Anshan Chemical, Fang Daxi ke Mo, Shanxi Macro, Henan evulekileyo carbon, Xuyang Group, Zaozhuang ukuvuselelwa, Ningxia Baichuan, Tangshan Dongri amandla amatsha, Taiyuan Sheng kwaye nangokunjalo.
