Ma ka ʻaoʻao maka o nā mea electrode maikaʻi ʻole, PetroChina a me CNOOC refineries e hoʻomau ʻia ma lalo o ke kaomi ʻana i nā hoʻouna coke haʻahaʻa-sulfur, a ke hoʻomau nei nā kumukūʻai kālepa mākeke. I kēia manawa, ua emi ke kumukūʻai o nā kumu waiwai graphite artificial a me nā uku hana graphitization, a ua hoʻokuʻu ʻia ka mana hana o ka ʻaoʻao hoʻolako. ʻO ka hiki ke hana i nā hiʻohiʻona haʻahaʻa haʻahaʻa a me waena o ka graphite artificial i ka mākeke ua lilo i mea nui, a ua alakaʻi i ka emi ʻana o nā kumukūʻai o kēia mau huahana. He 39,000-42,000 yuan/ton ka nui o ka electrode material graphite, graphite artificial he 50,000-60,000 yuan/ton, a me ka mesocarbon microspheres he 60-75,000 yuan/ton.
Mai ka hiʻohiʻona o ke kumu kūʻai, ka nila coke a me ka haʻahaʻa-sulfur coke, ka mea maka o ka graphite artificial, helu ma kahi o 20% -30% o ke kumu kūʻai, a ua emi ke kumukūʻai o nā mea maka mai ke kolu o ka hapaha.
ʻO ke kumu kūʻai o ka ʻaila ʻaila haʻahaʻa haʻahaʻa sulfur coke fluctuated hapa, a ʻo ke kumukūʻai o 2 # ma Kina Hikina a me Kina Hema i hāʻule e 200 yuan / ton, a ʻo ke kumukūʻai o kēia manawa he 4600-5000 yuan / ton. Ma ke ʻano o ka ʻoihana nui, ua hāʻule ʻo Huizhou CNOOC 1#B i 600 yuan/ton i 4750 yuan/ton. Ua hāʻule pinepine nā hale hana hoʻoheheʻe ma Shandong, a ua pāpā ʻia nā moku. ʻO ka emi ʻana o ke kumukūʻai o ka ʻaila coke ua hoʻomaikaʻi i ka palena waiwai o nā ʻoihana coke calcined, a ua paʻa ka hana o nā ʻoihana coke calcined. ʻO ke kumukūʻai o ka slurry ʻaila haʻahaʻa haʻahaʻa, ka mea maka o ka coke needle, hoʻomau i ka hāʻule ʻana a aia i kēia manawa ma 5,200-5,220 yuan / ton. Ua hoʻokuʻu iki kekahi mau hui ʻaila coke no ka manawa lōʻihi, ua lawa ka lako nui o ka coke nilala, ke hoʻomau nei nā poʻe o ka lanahu i nā poho, a ke hoʻoholo ʻia nei ka manawa hoʻomaka.
ʻO ke kumukūʻai o ka hana graphitization i helu ʻia ma kahi o 50%. I ke kolu o ka hapaha, ma muli o ka hoʻokuʻu ʻia ʻana o ka mana hana ʻaoʻao hoʻolako, ua hōʻemi mālie ka ʻāpana mākeke, a hoʻomaka ka emi ʻana o nā uku hana.
Mai ka manaʻo o ka lako, hoʻomaka ke kolu o ka hapaha e komo i kahi manawa o ka ulu pahū i ka hana electrode maikaʻi ʻole. ʻO nā papahana hana electrode maikaʻi ʻole mua i hiki i ka mana hana a ua hoʻokuʻu ʻia nā papahana hou. Ua piʻi koke ka lako o ka mākeke.
Eia nō naʻe, lōʻihi ka pōʻai hana o ka graphite artificial, a ua kūkākūkā ʻia ke kumukūʻai o ka anode a me ka graphitization no kekahi mau hapaha o kēia makahiki. I ke kolu o ka hapaha, aia ka hale hana anode a me ka lalo i kahi kahua pāʻani kumukūʻai. ʻOiai ua hemo ke kumukūʻai huahana, ʻaʻole ia he manaʻo ua hāʻule nui ke kumukūʻai.
I ka hapaha ʻehā, ʻoi aku ka hoʻomaka ʻana mai Nowemapa, ua hoʻopaʻa ʻia nā ʻoihana pākaukau i nā hana mālama, a ua nāwaliwali ke koi no nā anodes; a ma ke ʻano o ka hoʻolako ʻana, ma waho aʻe o ka mana hana hou o nā mea hana anode kuʻuna i hoʻokuʻu mālie ʻia i kēia makahiki, aia kekahi mau hale anode liʻiliʻi a i ʻole nā mea hou i hoʻohui i nā mana hou i kēia makahiki. Me ka hoʻokuʻu ʻana i ka mana hana, ʻoi aku ka nui o ka mana electrode maikaʻi ʻole o nā hiʻohiʻona haʻahaʻa a me waena o ka mākeke; ua emi ke kumu kūʻai o ka hopena-coke a me nā kumukūʻai graphitization, i alakaʻi i ka hoʻohaʻahaʻa holoʻokoʻa i ke kumukūʻai o nā huahana electrode maikaʻi ʻole.
I kēia manawa, ʻo kekahi mau huahana haʻahaʻa haʻahaʻa a waena waena me ka universality ikaika e ʻoki mau ana i nā kumukūʻai, ʻoiai ʻo kekahi mau huahana kiʻekiʻe me nā pono ʻenehana ikaika mai nā mea hana nui ʻaʻole hiki ke hoʻonui a hoʻololi ʻia, a e kūpaʻa mau nā kumukūʻai i ka wā pōkole. .
ʻOi aku ka nui o ka mana hana nominal o ka electrode maikaʻi ʻole, akā ma muli o ka mana o ke kapikala, ʻenehana, a me ke kahe o lalo, ua lohi kekahi mau ʻoihana electrode maikaʻi ʻole i ka manawa hana.
Ke nānā nei i ka mākeke electrode maikaʻi ʻole ma ke ʻano holoʻokoʻa, ma muli o ka mana o ke kulekele kōkua, ua kaupalena ʻia ka ulu ʻana o ka mākeke kaʻa kaʻa hou, a ʻo ka hapa nui o nā ʻoihana pākaukau e hoʻopau i ka waihona. Ua like pū me ka lā o ke kau inoa ʻana i ka ʻaelike i kēia makahiki aʻe.
Graphitization: Ua hōʻemi ʻia nā pilikia logistic a me ka halihali i ka hopena o ka maʻi ahulau ma Inner Mongolia a me nā wahi ʻē aʻe, akā ma muli o ka hopena o ka hiki ke hana a me nā mea maka, ke kū nei ke kumu kūʻai o ka graphitization OEM i ke ʻano i lalo. ke hoʻomau nei ka nāwaliwali o ke kākoʻo ʻana i nā kumu kūʻai he nui no nā mea anode graphite artificial. I kēia manawa, i mea e hoʻomalu ai i nā kumukūʻai a hōʻemi i ka hopena o ka hoʻopau ʻana i ka hāʻawi ʻana, nui nā hale hana anode e koho e waiho i kahi kaulahao ʻoihana piha e hoʻonui ai i kā lākou hoʻokūkū. I kēia manawa, he 17,000-19,000 yuan/ton ke kumu kūʻai nui o ka multi-graphitization. Nui nā lako o nā kapuahi paʻa a paʻa nā kumukūʻai.
