ʻO nā ʻokoʻa koʻikoʻi ma waena o ka Graphitized Petroleum Coke a me ka Ordinary Petroleum Coke

1. ʻAno Hoʻonohonoho ʻAtomika: He Hoʻololi Kūlana Mai ka Maʻi a i ke Kauoha

• ʻO ka Coke Petroleum Maʻamau: Hoʻonohonoho ʻia nā ʻātoma kalapona i kahi kūlana i hoʻonohonoho ʻole ʻia a i ʻole kahi kūlana pōkole, e like me ke ʻano o ke kalapona amorphous. He nui nā hemahema lattice, e kaupalena ana i kona conductivity uila, conductivity thermal, a me ke kūpaʻa kemika.
• ʻO Graphitized Petroleum Coke: Ma hope o ka mālama ʻana i ka graphitization ma kahi mahana kiʻekiʻe o kahi 3000°C, ua hoʻonohonoho hou ʻia nā ʻātoma kalapona i loko o kahi ʻano graphite papa hexagonal. Loaʻa i kēia ʻano ke kūpaʻa lattice kiʻekiʻe, nā ikaika interlayer nāwaliwali, a me ke kū'ē haʻahaʻa o ka neʻe ʻana o ka electron. Hāʻawi kēia hoʻololi ʻano iā ia me nā waiwai graphite maʻamau, e like me ke alakaʻi uila kiʻekiʻe, ke alakaʻi wela kiʻekiʻe, a me ke kūpaʻa kemika maikaʻi loa.

2. Nā ʻokoʻa hana: Hoʻoholo ka ʻōnaehana i ka hana

Ka Hoʻokele Uila a me ka Wera

• ʻO ka Coke Petroleum Graphitized: ʻOi aku ka haʻahaʻa o kona resistivity ma mua o ka coke petroleum maʻamau (hiki ke haʻahaʻa ma lalo o 0.001 Ω·m), a ʻoi aku ka kiʻekiʻe o kona conductivity thermal. He kūpono ia no nā hiʻohiʻona me nā koi koʻikoʻi ma ka conductivity uila a me ka thermal (e laʻa, nā mea anode no nā pila lithium-ion, nā electrodes graphite mana kiʻekiʻe).
• ʻO ka Coke Petroleum Maʻamau: Ma muli o nā hemahema kūkulu, he haʻahaʻa kona conductivity uila a hoʻohana nui ʻia i nā kahua me nā koi hana haʻahaʻa (e laʻa, wahie, nā mea kalapona maʻamau).

Paʻa Kemika

• ʻO Graphitized Petroleum Coke: Hoʻonui kona ʻano papa i kona kūpaʻa ʻana i ka pala kemika mai nā waikawa, alkalis, a me nā mea ʻē aʻe. ʻAʻole ia e maʻalahi i ka oxidation a me ka hōʻino ʻana i nā mahana kiʻekiʻe, e hopena ana i kahi ola lawelawe lōʻihi.
• ʻO ka Coke Petroleum maʻamau: He mea hiki ke hōʻino ʻia ke kūkulu ʻana i nā wahi wela kiʻekiʻe a i ʻole nā ​​​​​​wahi ʻino, e alakaʻi ana i ka hōʻemi wikiwiki ʻana o ka hana.

Ka ʻIkepili Haumia

• ʻO Graphitized Petroleum Coke: Hiki i ke kaʻina hana graphitization ke hōʻemi hou i ka nui o nā mea haumia e like me ka sulfur a me ka naikokene (hiki ke hoʻemi ʻia ka nui o ka sulfur i lalo o 0.1%), e hōʻemi ana i ka haumia a me nā hopena maikaʻi ʻole i ka wā o ke kaʻina hana hoʻoheheʻe (e laʻa, nā pores a me nā māwae i loko o nā mea i hoʻolei ʻia).
• ʻO ka Coke Petroleum Maʻamau: Loaʻa iā ia kahi ʻike haumia kiʻekiʻe a koi ʻia ka mālama mua ʻana (e laʻa, calcination) e hoʻokō i nā pono o kekahi mau noi ʻoihana.

3. Nā Kahua Noi: Hoʻokele nā ​​ʻokoʻa hana i ka ʻokoʻa o ke koi

ʻO ka Coke ʻAila Graphitized

• ʻO ka Metallurgy Kiʻekiʻe: Ma ke ʻano he carburizer, hiki iā ia ke hoʻonui pono i ka ʻike kalapona o ka hao hoʻoheheʻe ʻia a hoʻomaikaʻi i nā waiwai o ke kila (e laʻa, ikaika, paʻakikī), me ka hōʻemi ʻana i ka hoʻokomo ʻana o nā mea ʻino e like me ka sulfur a me ka naikokene.
• Nā Mea Ikehu Hou: He mea nui ia no nā mea anode o nā pila lithium-ion. ʻO kona conductivity uila kiʻekiʻe a me kona ʻano papa e kōkua i ka hoʻomaikaʻi ʻana i ka pono o ka hoʻouka ʻana a me ke ola pōʻaiapuni o nā pila.
• Nā Huahana Kalapona Kūikawā: Hoʻohana ʻia i ka hana ʻana o nā poloka cathode nui, nā electrodes graphitized, a me nā mea ʻē aʻe, e hilinaʻi ana i kona maʻemaʻe kiʻekiʻe, crystallinity kiʻekiʻe, a me ke kūpaʻa wela kiʻekiʻe.

Coke ʻaila maʻamau

• Kahua Wahie: Hoʻohana pinepine ʻia ka coke sulfur kiʻekiʻe i nā hale hana sima, nā hale hana aniani, nā mea kanu mana, a me nā mea ʻē aʻe, ma ke ʻano he wahie haʻahaʻa ke kumu kūʻai.
• Nā Mea Kalapona Kumu: Hiki ke hoʻohana ʻia ka coke haʻahaʻa-sulfur, ma hope o ka calcination, i ka hana ʻana o nā anodes no ka electrolysis alumini, nā electrodes graphite maʻamau, a me nā mea ʻē aʻe, akā ʻoi aku ka haʻahaʻa o kāna hana ma mua o nā huahana graphitized.

4. Kaʻina Hana: He Kūʻai ma waena o ka Mahana a me ke Kumukūʻai

• ʻO ka Coke Petroleum Maʻamau: Hana ʻia ma o ke kaʻina hana coking lohi a i ʻole ke kaʻina hana coking wai, me nā kumukūʻai haʻahaʻa. Eia nō naʻe, pono ia i ka calcination hou aʻe (ma kahi o 1300°C) e wehe i nā ʻāpana volatile a me ka makū, a laila e hoʻonui ai i ka nui o ke kalapona paʻa.
• ʻO ka Coke Petroleum Graphitized: Ke hoʻohana nei i ka coke petroleum maʻamau ma ke ʻano he mea maka, pono ia i kahi hana graphitization wela kiʻekiʻe ma kahi o 3000°C. Hoʻonui nui kēia i ka hoʻohana ʻana i ka ikehu a me nā kumukūʻai lako, akā ʻoi aku ka waiwai i hoʻohui ʻia o ka huahana.
