ʻO Needle coke kahi 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.He ʻano kahe kahe kona ʻano, 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.
E like me 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 ʻaila coke.ʻO ka nila coke i hana ʻia mai ka lanahu tar pitch a ʻo kāna hakina he coke 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, lehu maʻi, thermal expansion coefficient, resistivity, vibration density, etc. papa kiʻekiʻe (papa maikaʻi), papa ʻekahi a me ka papa ʻelua.
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 aila-series needle coke ma mua o ko ka coal-series needle coke, ka mea ma muli o ka hoʻonui ʻia ʻana o ka coke needle coal-series i ka wā 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 ke kinikini 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, ʻo 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 wela 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 ka moʻo graphitization kaʻina hana hana, ka lanahu ana needle coke ma ka hoʻohui ʻana i nā mea hoʻohui e hoʻomalu i kona hoʻonui ʻana, hiki ke hoʻemi ʻia ka helu hoʻonui.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 ʻoi aku ka liʻiliʻi o ka coke needle coke 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 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 i 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 koila, me ka ʻole o ka pono o ka 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, ʻo nā ʻoihana hana nui o ka aila ʻaila coke: Weifang Fumei hou Energy, Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei hou ikehu, Shandong Yiwei, Sinopec jinling Petrochemical, Maoming petrochemical, etc. Lahu moʻo nila coke mainstream hana ʻoihana Baowu kalapona mea, Baotailong ʻenehana, Anshan wehe 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 laila.
