ʻO ka graphite maʻemaʻe kiʻekiʻepili i ka graphite me kahi maʻiʻo kalapona i ʻoi aku ma mua o 99.99%.Loaʻa i ka graphite maʻemaʻe kiʻekiʻe e like me ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka corrosion, ka pale ʻana i ka haʻalulu wela, ka hoʻonui haʻahaʻa haʻahaʻa haʻahaʻa, ka lubrication ponoʻī, ka coefficient kūʻē haʻahaʻa, a me ka hana mīkini maʻalahi.ʻO ka hana ʻana i ka noiʻi e pili ana i ke kaʻina hana o ka graphite maʻemaʻe kiʻekiʻe a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana he mea koʻikoʻi nui ia no ka hoʻomohala ʻana i ka ʻoihana graphite maʻemaʻe kiʻekiʻe o Kina.
I mea e hoʻoikaika ai i ka hoʻomohala ʻana o ka ʻoihana graphite maʻemaʻe kiʻekiʻe o Kina, ua hoʻokomo kā mākou hui i ka nui o nā manpower a me nā kumuwaiwai i ka noiʻi a me ka hoʻomohala ʻana i ka graphite maʻemaʻe kiʻekiʻe kiʻekiʻe, e hāʻawi nui ana i ka localization o ka graphite maʻemaʻe kiʻekiʻe.I kēia manawa, e haʻi wau iā ʻoe e pili ana i kā mākou ʻoihana noiʻi a me nā holomua hoʻomohala:
- Kaʻina hana maʻamau no ka hana ʻana i ka graphite maʻemaʻe kiʻekiʻe:
Hōʻike ʻia ke kaʻina hana nui o ka graphite maʻemaʻe kiʻekiʻe ma ka Figure 1. Ua ʻike ʻia he ʻokoʻa ke kaʻina hana o ka graphite maʻemaʻe kiʻekiʻe mai nā electrodes graphite.Pono ka graphite maʻemaʻe kiʻekiʻe i nā kumu waiwai isotropic, pono e hoʻoheheʻe ʻia i mau pauka ʻoi aku ka maikaʻi.Pono e hoʻohana ʻia ka ʻenehana hoʻoheheʻe Isostatic, a lōʻihi ka pōʻai ʻai.I mea e hoʻokō ai i ka nui i makemake ʻia, koi ʻia nā pōʻai hoʻoheheʻe impregnation he nui, a ʻoi aku ka lōʻihi o ka pōʻaiapili graphitization ma mua o ka graphite maʻamau.
1.1 Mea maka
ʻO nā mea maka no ka hana ʻana i ka graphite maʻemaʻe kiʻekiʻe e loaʻa i nā aggregates, binders, a me nā mea hana impregnating.Hana ʻia nā mea hōʻuluʻulu me ka ʻaila ʻaila coke a me ka asphalt coke.ʻO kēia ke kumu no ka loaʻa ʻana o nā hiʻohiʻona o ka ʻaila coke me ka lehu haʻahaʻa (maʻamau ma lalo o 1%), maʻalahi ka graphitization i nā wela kiʻekiʻe, conductivity maikaʻi a me ka conductivity thermal, a me ka helu hoʻonui laina haʻahaʻa;ʻO ka graphite i loaʻa ma ka hoʻohana ʻana i ka asphalt coke ma ka mahana like graphitization he kiʻekiʻe ka resistivity uila akā ʻoi aku ka ikaika mechanical.No laila, i ka wā e hana ai i nā huahana graphitized, ma kahi o ka petroleum coke, hoʻohana ʻia kahi hapa o ka coke asphalt e hoʻomaikaʻi i ka ikaika mechanical o ka huahana.Hoʻohana maʻamau nā mea hoʻopaʻa paʻa i ka pitch tar lanahu,ʻo ia ka huahana o ke kaʻina hana distillation o ke kola lanahu.He paʻa ʻeleʻele ma ka lumi wela a ʻaʻohe wahi hoʻoheheʻe paʻa.
1.2 Calcination / Hoʻomaʻemaʻe
ʻO ka Calcination e pili ana i ka hoʻomaʻamaʻa wela wela o nā ʻano kalapona paʻa paʻa ma lalo o nā kūlana ea kaʻawale.Loaʻa i nā ʻāpana i koho ʻia nā ʻokoʻa ʻokoʻa o ka makū, nā haumia, a i ʻole nā mea hikiwawe i loko o ko lākou hale ma muli o nā ʻokoʻa o ka mahana coking a i ʻole ka makahiki geological o ka hoʻokumu ʻana i ka lanahu.Pono e hoʻopau ʻia kēia mau mea ma mua, i ʻole e hoʻopilikia i ka maikaʻi o ka huahana a me ka hana.No laila, pono e hoʻomaʻemaʻe ʻia nā mea i koho ʻia.
1.3 wili
ʻO nā mea paʻa paʻa i hoʻohana ʻia no ka hana graphite, ʻoiai ua hoʻemi ʻia ka nui o ka poloka ma hope o ka calcination a i ʻole ka hoʻomaʻemaʻe ʻana, ʻoi aku ka nui o ka nui o nā ʻāpana me nā loli nui a me nā ʻano like ʻole.No laila, pono e ʻokiʻoki i ka nui o ka ʻāpana aggregate e hoʻokō i nā koi hoʻohui.
1.4 Ka hui ʻana a me ka hui ʻana
Pono e hui pū ʻia ka lepo lepo me ka mea hoʻopaʻa kohu lanahu ma mua o ka hoʻokomo ʻia ʻana i loko o ka mīkini wili wela no ka hui ʻana e hōʻoia i ka hāʻawi like ʻana o ka mea.
1.5 Hoʻokumu
ʻO nā ala nui e pili ana i ka extrusion molding, molding, vibration molding, a me isostatic pressing molding
1.6 Bakina
Pono nā huahana kalapona i hoʻokumu ʻia i kahi kaʻina hoʻoheheʻe, kahi e komo ai ka carbonizing i ka binder i loko o ka binder coke ma o ka mālama wela (ma kahi o 1000 ℃) ma lalo o nā kūlana ea kaʻawale.
1.7 Impregnation
ʻO ke kumu o ka impregnation ʻo ia ka hoʻopiha ʻana i nā pores liʻiliʻi i hana ʻia i loko o ka huahana i ka wā o ke kaʻina hana me ka asphalt hoʻoheheʻe ʻia a me nā mea hana impregnating ʻē aʻe, a me nā pores wehe i loaʻa i nā ʻāpana coke aggregate, e hoʻomaikaʻi i ka nui o ka nui, conductivity, ikaika mechanical, a me ka pale ʻana i ka corrosion kemika o ka huahana.
1.8 Kiʻi kiʻi
ʻO ka graphitization e pili ana i ke kaʻina hana wela wela e hoʻololi i ke kalapona graphite ʻole i thermodynamically paʻa ʻole i kalapona graphite ma o ka hoʻōla wela.
Welina mai e kipa a nānā i kā mākou hale hana, hana nui i nā graphite molds, high-purity graphite, graphite crucibles, nano graphite powder, isostatic pressing graphite, graphite electrodes, graphite rods, a pēlā aku.
