ʻO Needle coke kahi ʻano ʻano kiʻekiʻe i hoʻomohala ikaika ʻia i nā mea kalapona. ʻO kona hiʻohiʻona he paʻa porous me ke kala hina a me ka luster metala. ʻO ke ʻano o kona ʻano he ʻano kahe kahe, me nā puka nui akā liʻiliʻi a me ke ʻano oval iki. ʻO ia ka mea maka no ka hana ʻana i nā huahana kalapona kiʻekiʻe e like me ka electrode mana kiʻekiʻe kiʻekiʻe, nā mea kalapona kūikawā, ka fiber carbon a me kāna mea hoʻohui.
Wahi a nā ʻano mea like ʻole, hiki ke hoʻokaʻawale ʻia ka ʻaila coke i loko o ka coke needle coke a me ka coke needle coke. ʻO ka coke needle i hana ʻia mai ke koena o ka aila ʻaila coke. ʻO ka nila coke i hana ʻia mai ka lanahu tar pitch a ʻo kāna hakina ʻo ia ka coke series needle coke.
ʻO nā mea kikoʻī e pili ana i ka maikaʻi o ka coke needle, ʻo ia ka density maoli, sulfur content, nitrogen content, volatile matter, ash content, thermal expansion coefficient, resistivity, vibration density, etc.
ʻO nā ʻokoʻa hana ma waena o ka lanahu a me ka ʻaila nilala coke e pili ana i kēia mau helu.
1. Ma lalo o nā kūlana like, ʻoi aku ka maʻalahi o ka graphite electrode i hana ʻia me ka coke needle coke ma mua o ka coke needle coke.
2. Ma hope o ka hana ʻana i nā huahana graphite, ʻoi aku ka kiʻekiʻe o ka nui a me ka ikaika o nā huahana graphitized o ka coke needle oil-series ma mua o ka coke needle coal-series, ʻo ia ke kumu o ka hoʻonui ʻana o ka coke needle coal-series i ka graphitization.
3. I ka hoʻohana kikoʻī ʻana i ka electrode graphite, ʻo ka huahana graphitized o ka coke needle aila he haʻahaʻa haʻahaʻa o ka hoʻonui wela.
4. Ma ke ano o ke kino a me ka kemika indexes o ka graphite electrode, ke ku'eku'e kiko'ī o ka graphitized huahana o ka aila koila coke ua oi iki ma mua o ka lanahu koila huahana coke.
5. ʻO ka mea nui loa ka hoʻonui ʻana o ka coke needle coke i ka wā e piʻi ai ka mahana i 1500-2000 ℃ i ke kaʻina o ka graphitization kiʻekiʻe, no laila e hoʻomalu pono ʻia ka piʻi ʻana o ka mahana, ʻaʻole wikiwiki ka piʻi ʻana o ka mahana, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ke kaʻina hana graphitization hana. Akā ʻoi aku ka paʻakikī o ka loaʻa ʻana o ka coke needle aila.
6. ʻOi aku ka liʻiliʻi o ka coke a me ka nui o ka coke needle coke, ʻoiai ʻo ka coke needle coke he mea liʻiliʻi a me ka nui o ka nui o ka nui (35 - 40 mm), hiki ke hoʻokō i nā koi o ka nui o nā mea hoʻohana.
7. E like me ka hoʻokomo ʻia ʻana o Japan Petroleum Coke Company, ua manaʻo ʻia ʻoi aku ka maʻalahi o ka hui ʻana o ka coke needle coke ma mua o ka coke needle coke, no laila ua maʻalahi ka mālama ʻana i ka manawa coking a me ka wela.
Mai ka mea i luna, aila niila coke he eha haʻahaʻa: haʻahaʻa wahaheʻe kiko'ī umekaumaha, haʻahaʻa ikaika, haʻahaʻa CTE, haʻahaʻa kiko'ī kū'ē, ka mua elua haʻahaʻa i graphite huahana, ka hope elua haʻahaʻa i graphite huahana mea maikai. ʻO ka holoʻokoʻa, ʻoi aku ka maikaʻi o nā indexes hana o ka aila moʻo nila coke ma mua o ka coal series needle coke, a ʻoi aku ka nui o ka noi noi.
I kēia manawa, ʻo ka graphite electrode ka mākeke koi nui no ka coke needle, e helu ana ma kahi o 60% o ka noi holoʻokoʻa o ka coke needle, ʻoiai ʻo nā ʻoihana electrode e loaʻa i nā koi maikaʻi loa no ka coke nila, me ka ʻole o ke koi pono pilikino. ʻOi aku ka ʻokoʻa o ke koi coke o ka lithium ion battery anode, ʻoi aku ka maikaʻi o ka mākeke kikohoʻe kiʻekiʻe i ka aila i kuke ʻia, ʻoi aku ka hilinaʻi o ka mākeke pākahi i ka coke me ka hana kiʻekiʻe.
Loaʻa i ka hana ʻana i ka coke Needle kekahi paepae ʻenehana, no laila, ʻano kakaikahi nā ʻoihana kūloko. I kēia manawa, ka home mainstream hana 'oihana o ka aila nila coke: Weifang Fumei hou Energy, Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei hou ikehu, Shandong Yiwei, Sinopec jinling Petrochemical, Anohana petrochemical, etc. kalapona, Anshan Chemical, Fang Daxi ke Mo, Shanxi Macro, Henan wehe kalapona, Xuyang Group, Zaozhuang revitalization, Ningxia Baichuan, Tangshan Dongri ikehu hou, Taiyuan Shengxu a pela aku.
