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. ʻIke ʻia ke ʻano kahe o 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, carbon fiber a me kāna mau mea hoʻohui.
E like me nā mea hana like ʻole, hiki ke hoʻokaʻawale ʻia ka coke needle i loko o ka hui aila a me ka moʻo lanahu ʻelua ʻano o ka coke nila. ʻO ka ʻaila coke i hana ʻia me ke koena ʻaila ma ke ʻano he mea maka ʻo ia ka hui ʻaila coke. ʻO ka coke ana nilala lanahu i hana ʻia mai ka pitch tar pitch a ʻo kona hakina i kapa ʻia ʻo coal measure needle coke.
ʻO nā mea kikoʻī e pili ana i ka maikaʻi o ka coke needle, ʻo ia nō ka nui maoli, sulfur content, nitrogen content, volatile content, ash content, thermal expansion coefficient, uila resistivity, vibration-solid density, etc. e mahele i ka papa kiekie (superior grade), ka papa mua a me ka papa elua.
ʻO ka ʻokoʻa o ka hana ma waena o ka coke needle coke ana a me ka coke ana needle coke e pili ana i kēia mau mea.
1. Ma lalo o nā kūlana like, ʻoi aku ka maʻalahi o ka hana ʻana i ka electrode graphite i hana ʻia i ka coke needle coke ma mua o ka coal series needle coke ma ke ʻano o ka hana.
2. Ma hope o ka hana ʻia ʻana o nā huahana graphite, ʻoi aku ka ʻoi aku ka kiʻekiʻe o nā huahana graphitized o ka aila moʻo nila coke ma mua o ko ka lanahu series needle coke, ka mea i hoʻonui ʻia ma ka hoʻonui ʻana o ka coal series needle coke i ka wā graphitization.
3. I ka hoʻohana kikoʻī ʻana o ka graphite electrode, nā huahana graphitized me 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 graphitized huahana o ka aila moʻo needle coke mea iki oi ma mua o ka lanahu series needle coke huahana.
5. ʻO ka mea nui loa, ʻo ka hoʻonui ʻana o ka coke needle coke i ke kaʻina o ka graphitization kiʻekiʻe, ke piʻi ka mahana i 1500-2000 ℃, no laila e mālama pono ʻia ka wikiwiki o ka piʻi ʻana o ka mahana, ʻaʻole wikiwiki ka wela, ʻoi aku ka maikaʻi. hoʻohana i ke kaʻina hana graphitization series, ana i ka lanahu coke needle ma ka hoʻohui ʻana i nā mea hoʻohui e kāohi i kona hoʻonui ʻana, hiki ke hoʻemi ʻia ka helu hoʻonui. Akā ʻoi aku ka paʻakikī o ka loaʻa ʻana o ka coke needle based oil.
6. ʻO ka ʻōnaehana ʻaila calcined i ʻoi aku ka liʻiliʻi o ka coke maʻiʻo a me ka nui o ka palaoa, ʻoiai ka liʻiliʻi o ka coke ma ke ana ʻana o ka lanahu a me ka nui o ka palaoa nui (35-40 mm), hiki ke hoʻokō i ka nui o ka palaoa e koi ai i ke ʻano, akā lawe mai ka paʻakikī. i ka paʻi ʻana o ka mea hoʻohana.
7. Wahi a Japan Petroleum Coke Company, ua manaʻo ʻia ʻoi aku ka maʻalahi o ka hui ʻana o ka hui aila moʻo koina coke ma mua o ko ka lanahu series needle coke, no laila ua maʻalahi ke kāohi i ka wā o ka coking kaʻina.
Mai ka manaʻo o luna, ʻehā haʻahaʻa ka ʻaila nele coke: haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa ikaika, haʻahaʻa CTE, haʻahaʻa haʻahaʻa kūʻokoʻa, ʻelua haʻahaʻa haʻahaʻa ma nā huahana graphite, maikaʻi nā haʻahaʻa hope ʻelua ma nā huahana graphite. ʻO ka mea maʻamau, ʻoi aku ka maikaʻi o nā ʻōlelo kuhikuhi hana o ka aila moʻo nila coke ma mua o ko ka lanahu moʻo nila coke, a ʻoi aku ka nui o ka noi noi.
I kēia manawa, ʻo ka graphite electrode ka mākeke koi nui o ka coke needle, e helu ana ma kahi o 60% o ka noi holoʻokoʻa o ka coke needle, a ʻo nā ʻoihana electrode i koi maopopo no ka pono coke needle, me ka ʻole o ke koi pono pilikino. ʻOi aku ka nui o nā koi like ʻole o ka lithium ion battery anode no ka nila coke, ʻoi aku ka makemake o ka mākeke kikohoʻe kiʻekiʻe kiʻekiʻe i ka aila i kuke ʻia, ʻoi aku ka hilinaʻi o ka mākeke pākēneka i ka coke maka.
ʻO ka hana ʻana o ka coke needle he paepae ʻenehana, no laila he liʻiliʻi nā ʻoihana kūloko. I kēia manawa, ʻo nā mea hana nui o ka aila ʻaila coke ko Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei New Energy, Shandong Yiwei, Sinopec Jinling Petrochemical, Maoming Petrochemical, etc. ʻO nā mea hana nui o ke ana lanahu needle coke he 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, etc.
