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 he coke needle coke.
ʻO nā indexes e pili ana i ka maikaʻi o ka coke needle e pili ana i ka nui maoli, sulfur content, nitrogen content, volatile matter, ash content, 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 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, 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 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 ʻole 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 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, 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. . . a pela aku.
