Needle coke ke mofuta oa boleng bo holimo o ntlafalitsoeng ka matla ka thepa ea khabone. Ponahalo ea eona ke porous solid le silevera ea bohlooho le metallic luster. Sebopeho sa eona se na le sebopeho se hlakileng sa phallo, se nang le masoba a maholo empa a seng makae le sebopeho sa oval hanyenyane. Ke thepa e tala bakeng sa ho hlahisa lihlahisoa tse phahameng tsa carbon tse kang li-electrode tse phahameng haholo, lisebelisoa tse khethehileng tsa carbon, carbon fiber le lisebelisoa tsa eona tse kopantsoeng.
Ho ea ka lisebelisoa tse fapaneng tsa tlhahiso, coke ea nale e ka aroloa ka letoto la oli le letoto la mashala mefuta e 'meli ea coke ea nale. The nale coke e hlahisoang ka masala a petroleum e le lisebelisoa tse tala ke letoto la nale coke. Nale ea mashala e lekanyang coke e hlahisoang ho tsoa ho sekontiri sa mashala 'me karoloana ea eona e bitsoa coal measure needle coke.
Li-index tse amang boleng ba nale coke li kenyelletsa boima ba 'nete, sebabole, dikahare tsa naetrojene, litaba tse feto-fetohang, litaba tsa molora, coefficient ea ho atolosa mocheso, resistivity ea motlakase, vibration-solid density, joalo-joalo e arotsoe ka sehlopha sa super grade (high grade), sehlopha sa pele le sa bobeli.
Phapang ea ts'ebetso lipakeng tsa nale ea mashala le coke ea oli ea nale e kenyelletsa lintlha tse latelang.
1. Tlas'a maemo a tšoanang, graphite electrode entsoe ka oli letoto la nale coke ke ho le bonolo ho thehoa ho feta mashala letoto la lihlooho tse nale coke mabapi le tshebetso.
2. Ka mor'a hore lihlahisoa tsa graphite li etsoe, lihlahisoa tsa graphite tsa oli ea letoto la nale coke li na le sekhahla se phahameng hanyenyane le matla ho feta a mashala letoto la nale coke, e bakoang ke ho atolosoa ha letoto la mashala la nale coke nakong ea graphitization.
3. Tšebelisong e khethehileng ea electrode ea graphite, lihlahisoa tsa graphite tse nang le oli ea nale ea oli li na le coefficient e tlase ea ho atolosa mocheso.
4. Mabapi le li-index tsa 'mele le lik'hemik'hale tsa electrode ea graphite, khanyetso e khethehileng ea lihlahisoa tsa graphitized tsa oli letoto la nale coke e phahame hanyenyane ho feta ea mashala letoto la lihlahisoa tsa nale coke.
5. Ntho ea bohlokoa ka ho fetisisa ke hore mashala a lekanya nale coke e atoloha nakong ea mocheso o phahameng oa graphitization, ha mocheso o fihla ho 1500-2000 ℃, kahoo lebelo la ho phahama ha mocheso le lokela ho laoloa ka thata, eseng ka potlako ho futhumatsa, ho molemo hore u se ke ua tela. sebelisa letoto la tlhahiso ea graphitization process, mashala a lekanya nale coke ka ho eketsa li-additives ho laola katoloso ea eona, sekhahla sa katoloso se ka fokotsoa. Empa ho thata ho feta ho finyella oli - e thehiloeng nale coke.
6. Sistimi ea oli ea calcined e na le li-coke tse nyane tse nyane le boholo bo botle ba lijo-thollo, athe nale ea tekanyo ea mashala e na le li-coke tse nyane le boholo ba lijo-thollo tse kholo (35-40 mm), tse ka fihlelang tlhoko ea boholo ba lijo-thollo tsa foromo, empa e tlisa bothata. ho tlatlapa ha mosebedisi.
7. Ho ea ka Japane Petroleum Coke Company, ho nkoa hore ho hlophisoa ha oli letoto la nale coke e bonolo ho feta ea mashala letoto la nale coke, kahoo ho bonolo ho laola nakong ea ho pheha.
Ho ea ka pono e ka holimo, tsamaiso ea oli ea nale coke e na le tse 'nè tse tlaase: matla a khoheli a tlaase, matla a tlaase, CTE e tlaase, ho hanyetsa ho khethehileng, tse peli tsa pele tse tlaase lihlahisoa tsa graphite, tse peli tsa ho qetela tse tlaase lihlahisoa tsa graphite li ntle. Ka kakaretso, li-index tsa ts'ebetso ea letoto la oli le nale coke li betere ho feta tsa letoto la mashala la nale, 'me tlhokahalo ea kopo e feta.
Hajoale, graphite electrode ke 'maraka o ka sehloohong oa tlhoko ea nale, o nkang karolo ea 60% ea kakaretso ea ts'ebeliso ea nale, mme likhoebo tsa li-electrode li na le tlhokahalo e hlakileng ea boleng ba nale, ntle le tlhokahalo ea boleng ba motho. Lisebelisoa tsa anode tsa lithium ion li na le tlhokahalo e fapaneng ea nale, 'maraka oa digital o phahameng o khetha oli e phehiloeng ka coke,' maraka oa betri ea matla o itšetlehile haholo ka coke e tala e theko e boima haholo.
Tlhahiso ea nale ea coke e na le moeli o itseng oa tekheniki, kahoo ho na le likhoebo tse fokolang tsa malapeng. Hajoale, lihlahisoa tse kholo tsa lihlahisoa tsa oli ea lapeng li kenyelletsa Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei New Energy, Shandong Yiwei, Sinopec Jinling Petrochemical, Maoming Petrochemical, joalo-joalo Bahlahisi ba ka sehloohong ba tekanyo ea mashala nale coke ke Baowu Carbon Material, Baotailong Technology, Anshan Kaitan, Angang Chemical, Fang Daxi Kemo, Shanxi Hongte, Henan Kaitan, Xuyang Group, Zaozhuang Zhenxing, Ningxia Baichuan, Tangshan Dongri New Energy, Taiyuan Shengxu, joalo-joalo.
