1. Malo ogwiritsira ntchito batri ya lithiamu anode:
Pakali pano, zinthu zamalonda za anode zimakhala makamaka ma graphite achilengedwe ndi graphite yokumba. Coke ya singano ndiyosavuta kujambulidwa ndipo ndi mtundu wapamwamba kwambiri wazinthu zopangira ma graphite. Pambuyo pa graphitization, imakhala ndi mawonekedwe owoneka bwino komanso ma graphite microcrystalline. Kumbali yakutali kwa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono timakhala ndi ubwino wa conductivity yabwino yamagetsi ndi matenthedwe. Coke ya singano imaphwanyidwa, yogawidwa, yopangidwa, granulated, ndi graphitized kuti ipeze zinthu zopangidwa ndi graphite, zomwe zimakhala ndi crystallinity ndi graphitization, ndipo ili pafupi ndi mawonekedwe abwino a graphite.
Makampani opanga magalimoto atsopano amphamvu akukula mofulumira m'zaka zaposachedwa. Kuyambira Januware mpaka Seputembara 2022, kuchuluka kwa mabatire amagetsi m'dziko langa ndi 372GWh, kuwonjezeka kwachaka ndi 176%. Bungwe la China Automobile Association likulosera kuti malonda onse a magalimoto amagetsi adzafika 5.5 miliyoni mu 2022, ndipo kuchuluka kwa magalimoto amagetsi chaka chonse kudzapitirira 5.5 miliyoni. 20%. Chifukwa cha "mzere wofiira woletsa kuyaka" padziko lonse lapansi komanso mfundo zapakhomo za "zolinga zapawiri za carbon", kufunikira kwapadziko lonse kwa mabatire a lithiamu akuyembekezeka kufika 3,008GWh mu 2025, ndipo kufunika kwa singano coke kudzafika matani 4.04 miliyoni.
2. Magawo ogwiritsira ntchito ma elekitirodi a graphite:
Needle coke ndi chinthu chapamwamba kwambiri chopangira ma elekitirodi a graphite apamwamba kwambiri. Maonekedwe ake ali ndi mawonekedwe opangidwa bwino a fibrous kapangidwe kake komanso kukula kwa tinthu tating'ono m'lifupi. Pa extrusion akamaumba, ndi yaitali olamulira ambiri particles anakonza pamodzi extrusion malangizo. . Kugwiritsiridwa ntchito kwa singano coke kupanga ma electrode apamwamba / apamwamba kwambiri a graphite kuli ndi ubwino wochepetsera resistivity, kutsika kwa kutentha kwapakati, kukana kwamphamvu kwa kutentha kwa kutentha, kugwiritsira ntchito ma electrode otsika komanso kachulukidwe kakang'ono kovomerezeka. Ma coke a singano opangidwa ndi malasha komanso opangidwa ndi mafuta ali ndi mawonekedwe awo pakuchita. Poyerekeza ndi ntchito ya singano ya singano, kuwonjezera pa kachulukidwe weniweni, kachulukidwe kameneka, mphamvu ya ufa, phulusa, sulfure, nayitrogeni, Kuphatikiza pa kufananiza zizindikiro za machitidwe ochiritsira monga chiŵerengero cha chiŵerengero ndi kukula kwa tinthu, kusamala kuyenera kuchitika. Komanso kulipidwa kwa matenthedwe kukulitsa koyenera, resistivity, compressive mphamvu, chochuluka kachulukidwe, kachulukidwe weniweni, kuchulukira chochuluka, anisotropy, uninhibited dziko ndi Analysis ndi kuwunika zizindikiro khalidwe monga deta kukulitsa mu boma loletsa, osiyanasiyana kutentha pa kukulitsa ndi contraction, etc. zizindikiro izi khalidwe ndi zofunika kwambiri kusintha magawo ndondomeko kupanga maelekitirodi graphite ndi kulamulira ntchito maelekitirodi graphite. Pazonse, magwiridwe antchito a singano opangidwa ndi mafuta ndi apamwamba pang'ono kuposa a coke ya singano yopangidwa ndi malasha.
Mabizinesi akunja akunja nthawi zambiri amasankha singano yamafuta apamwamba kwambiri ngati zida zazikulu zopangira ma elekitirodi a UHP ndi HP graphite. Mabizinesi a carbon ku Japan amagwiritsanso ntchito coke ya singano yopangidwa ndi malasha ngati zida zopangira, koma popanga ma elekitirodi a graphite omwe ali pansi pa Φ600mm. Ngakhale kupanga mafakitale a singano coke m'dziko langa mochedwa kuposa makampani akunja, izo zakula mofulumira m'zaka zaposachedwapa ndipo wayamba kupanga mawonekedwe. Pakalipano, magulu amphamvu kwambiri a graphite electrode aggregates a dziko langa amakhala makamaka opangidwa ndi singano coke. Pankhani ya kupanga kwathunthu, magawo opanga singano zapakhomo amatha kukwaniritsa zosowa zamabizinesi a carbon kuti apange ma elekitirodi apamwamba kwambiri a graphite a singano. Komabe, pali kusiyana kwina poyerekeza ndi makampani akunja mumtundu wa singano coke. Zida zazikulu zopangira ma graphite electrode zazikulu kwambiri zimadalirabe singano yochokera kunja, makamaka ma elekitirodi amphamvu kwambiri / opitilira mphamvu kwambiri amatumizidwa kunja. Singano coke ngati zopangira.
Mu 2021, kupanga zitsulo zapakhomo kudzakhala matani 1.037 biliyoni, omwe zitsulo za ng'anjo yamagetsi zimakhala zosakwana 10%. Unduna wa Zamakampani ndi Ukadaulo wa Zaukadaulo Pamodzi ukukonzekera kuwonjezera kuchuluka kwa ng'anjo yamagetsi yamagetsi kupitilira 15% mu 2025. Bungwe la National Iron and Steel Association likulosera kuti lidzafika 30% mu 2050. Idzafika 60% mu 2060. chiŵerengero cha steelmaking cha ng'anjo zamagetsi chidzayendetsa mwachindunji kufunikira kwa maelekitirodi a graphite, ndipo ndithudi, kufunika kwa singano coke.
