Hoʻolauna ʻana i nā ʻano hana synthesis ʻoihana a me nā hoʻohana ʻana o ka graphite i hoʻonui ʻia

ʻO ka graphite i hoʻonui ʻia, i ʻike ʻia hoʻi he graphite vermicular, he hui crystalline e hoʻohana ana i nā ʻano kino a kemika paha e hoʻokomo i nā mea hana non-carbon i loko o nā mea nanocarbon intercalated graphitic kūlohelohe a hui pū me nā mokulele pūnaewele hexagonal carbon me ka mālama ʻana i ke ʻano o ka papa Graphite. ʻAʻole ia e mālama wale i nā waiwai kino a me nā kemika maikaʻi loa o ka graphite, e like me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa corrosion, ka neutron flux, X-ray a me ka gamma-ray irradiation lōʻihi. Loaʻa iā ia nā waiwai kino a me nā kemika maikaʻi loa, e like me ke coefficient friction haʻahaʻa, ka lubrication ponoʻī maikaʻi, ka conductivity uila a me ka thermal, a me ka anisotropy. Eia kekahi, ma muli o ka pilina ma waena o ka mea i hoʻopili ʻia a me ka papa graphite, hōʻike ka graphite i hoʻonui ʻia i nā waiwai hou i loaʻa ʻole i ka graphite pristine a me ka mea i hoʻopili ʻia, a lanakila i ka brittleness a me ke kūpaʻa hopena o ka graphite kūlohelohe. Ke kaʻana like nei nā mea hoʻoponopono graphite Furuite i ka hoʻolauna ʻana i nā ʻano hana synthesis ʻoihana a me nā hoʻohana o ka graphite i hoʻonui ʻia:

1. Nā ʻano hana synthetic i hoʻohana pinepine ʻia i ka ʻoihana

①ʻOkiʻoki kemika

Nā Pōmaikaʻi: ʻO ka hoʻoheheʻe kemika kahi ʻano hana i hoʻohana nui ʻia a hoʻokumu maikaʻi ʻia i ka ʻoihana. No laila, he mau pono maopopo kona, ʻenehana paʻa a me ke kumukūʻai haʻahaʻa.

ʻO ka hemahema: ʻO ka mea hoʻohuihui ka waikawa sulfuric i hoʻopaʻa ʻia, kahi e hoʻopau ai i ka nui o ka waikawa. Aia ka haumia kinoea Sox i ke kaʻina hana, a ʻo nā koena i loko o ka huahana e hōʻino pū i nā lako hana synthesis.

②ʻOkika uila

E like me ka oxidation kemika, ʻo ia kekahi o nā ʻano hana synthesis ʻoihana maʻamau no ka graphite i hoʻonui ʻia.

Nā Pōmaikaʻi: ʻAʻole pono e hoʻohui i nā oxidants ikaika, e like me nā waikawa ikaika, a hiki ke hoʻomalu ʻia ka hopena ma ka hoʻoponopono ʻana i nā palena e like me ke au a me ke voltage. He maʻalahi nā lako hana synthesis, nui ka nui o ka synthesis, ʻaʻole haumia ka electrolyte, a hiki ke hoʻohana hou ʻia.

Nā Pōʻino: ʻOi aku ka maikaʻi ʻole o ke kūpaʻa o ka huahana i hana ʻia ma mua o nā ʻano hana ʻē aʻe, e pono ai nā lako kiʻekiʻe, a he nui nā mea e hoʻopilikia ai i ka maikaʻi o ka huahana. I kekahi manawa, ua emi nui ka nui o ka huahana ma muli o ka piʻi ʻana o ka mahana ambient. Eia kekahi, aia nā hopena ʻaoʻao ma nā kahe kiʻekiʻe i loko o nā hopena wai, no laila he paʻakikī ke loaʻa nā hui mua.

2. Nā ʻoihana hana nui a me ka hiki ke hana

Ua ulu ka hana ʻana o nā huahana graphite i hoʻonui ʻia ma koʻu ʻāina mai ka pae mua a hiki i ka ʻoi aku o 100 mau mea hana, me ka hana makahiki ma kahi o 30,000 tons, a ua haʻahaʻa ka nui o ka mākeke. Eia kekahi, ʻo ka hapa nui o nā mea hana he mau mea hoʻopiha sila haʻahaʻa, kakaʻikahi ka hoʻohana ʻia i nā sila kaʻa a me nā kukui mokulele nukelea. Eia nō naʻe, me ka hoʻomohala ʻana o ka ʻenehana kūloko, e piʻi mālie ka hapa o nā huahana kiʻekiʻe.

3. Ke koi ʻana o ka mākeke a me ka wānana o nā mea sila

I kēia manawa, hoʻohana nui ʻia ka graphite i hoʻonui ʻia e like me nā mea sila kaʻa, e like me nā gaskets cylinder, nā gaskets puka komo a me ka hoʻopau ʻana, a pēlā aku. Hoʻohana nui ʻia nā mea sila graphite i hoʻonui ʻia ma koʻu ʻāina e like me nā mea hoʻopiha sila. I kēia manawa, ua hoʻomohala ʻia ka graphite i hoʻonui ʻia me ka ʻike kalapona haʻahaʻa, hiki ke hōʻemi nui i ke kumukūʻai hana o ka graphite i hoʻonui ʻia, a laila e pani ana i ka asbestos ma kahi nui a hoʻonui i ke koi. Ma ka ʻaoʻao ʻē aʻe, inā hiki ke hoʻololi hapa ʻia nā mea sila plastik, rubber a me ka metala, e ʻoi aku ka nui o ke koi kūloko makahiki no nā mea sila graphite hiki ke hoʻonui ʻia.

I loko o ka ʻoihana kaʻa, pono kēlā me kēia gasket poʻo cylinder kaʻa, ka gasket puka ea a me ka puka hoʻopau ma kahi o 2 ~ 10kg o ka graphite i hoʻonui ʻia, a ʻo kēlā me kēia 10,000 kaʻa e pono ai he 20 ~ 100 tons o ka graphite i hoʻonui ʻia. Ua komo ka ʻoihana kaʻa o Kina i kahi manawa o ka ulu wikiwiki. No laila, ʻo ke koi makahiki o koʻu ʻāina no nā mea sila graphite i hoʻonui ʻia he mea paʻakikī loa ia.
