ʻO ka graphite i hoʻonui ʻia, ʻike ʻia hoʻi ʻo vermicular graphite, he pūhui crystalline e hoʻohana ana i nā ʻano kino a i ʻole kemika e intercalate i nā mea hoʻohālikelike non-carbon i loko o nā mea nanocarbon intercalated graphitic i hoʻohālikelike maoli ʻia a hui pū me nā mokulele hexagonal carbon me ka mālama ʻana i ka hoʻolālā papa Graphite. ʻAʻole wale ia e mālama i ka maikaʻi o ke kino a me nā waiwai kemika o ka graphite, e like me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa corrosion, neutron flux, X-ray a me ka gamma-ray lōʻihi irradiation. Loaʻa iā ia nā waiwai kino a me nā kemika, e like me ka coefficient friction haʻahaʻa, ka lubrication ponoʻī maikaʻi, ka uila a me ka wela, a me ka anisotropy. Eia kekahi, ma muli o ka pilina ma waena o ka mea intercalated a me ka papa graphite, hōʻike ka graphite i hoʻonui ʻia i nā waiwai hou i loaʻa ʻole i ka graphite pristine a me nā mea intercalated, a lanakila i ka brittleness a me ka hopena o ka graphite maoli. Kaʻana like nā mea hoʻoponopono graphite Furuite i ka hoʻolauna ʻana i nā ʻano hana synthesis a me ka hoʻohana ʻana i ka graphite i hoʻonui ʻia:
1. Hoʻohana mau ʻia nā ʻano hana synthetic i ka ʻoihana
①Ka hoʻoneʻe kemika
Pōmaikaʻi: ʻO ka oxidation kemika kahi hana i hoʻohana nui ʻia a paʻa i ka ʻoihana. No laila, loaʻa iā ia nā pōmaikaʻi, ʻenehana makua a me ke kumu kūʻai haʻahaʻa.
Ka pōʻino: ʻO ka mea intercalating ka mea maʻamau i ka sulfuric acid, e hoʻopau i ka nui o ka waikawa. Aia ka Sox ino kinoea pollution i loko o ke kaʻina hana, a me nā koena i loko o ka huahana e corrode ka synthesis lako.
②Electrochemical oxidation
E like me ka oxidation kemika, ʻo ia kekahi o nā ʻano hana synthesis maʻamau no ka graphite hoʻonui.
Pōmaikaʻi: ʻAʻole pono e hoʻohui i nā oxidants ikaika, e like me nā waikawa ikaika, a hiki ke hoʻomalu ʻia ka hopena ma o ka hoʻoponopono ʻana i nā ʻāpana e like me ka manawa a me ka uila. He maʻalahi nā mea hana synthesis, nui ka nui o ka synthesis, ʻaʻole haumia ka electrolyte, a hiki ke hoʻohana hou ʻia.
Nā hemahema: ʻOi aku ka maikaʻi o ka paʻa o ka huahana synthesized ma mua o nā ʻano hana ʻē aʻe, e koi ana i nā mea hana kiʻekiʻe, a he nui nā mea e pili ana i ka maikaʻi o ka huahana. I kekahi manawa, hoʻemi nui ʻia ka nui o ka huahana ma muli o ka piʻi ʻana o ka mahana ambient. Eia kekahi, aia nā ʻaoʻao ʻaoʻao i nā au kiʻekiʻe i nā wai wai, no laila paʻakikī ke kiʻi ʻana i nā pūhui mua.
2. ʻO nā ʻoihana hana nui a me ka hiki ke hana
ʻO ka hana ʻana o nā huahana graphite i hoʻonui ʻia ma koʻu ʻāina ua ulu aʻe mai ka pae mua i ʻoi aku ma mua o 100 mau mea hana, me ka hoʻopuka makahiki ma kahi o 30,000 tons, a ua haʻahaʻa ka mākeke. Eia kekahi, ʻo ka hapa nui o nā mea hana he mea hoʻopihapiha hoʻopihapiha haʻahaʻa haʻahaʻa, ʻaʻole i hoʻohana ʻia i nā sila kaʻa a me nā kukui lele nuklea. Eia naʻe, me ka hoʻomohala ʻana o ka ʻenehana kūloko, e piʻi mālie ka hapa o nā huahana kiʻekiʻe.
3. Ke koi makeke a me ka wanana o na mea sila
I kēia manawa, hoʻohana nui ʻia ka graphite i hoʻonui ʻia e like me nā mea hoʻopili kaʻa, e like me nā gaskets cylinder, intake a me exhaust port gaskets, etc. I kēia manawa, ua hoʻomohala ʻia ka graphite hoʻonui me ka haʻahaʻa kalapona haʻahaʻa, hiki ke hoʻemi nui i ke kumukūʻai hana o ka graphite i hoʻonui ʻia, a laila e hoʻololi i ka asbestos ma kahi nui a hoʻonui i ka noi. Ma ka ʻaoʻao ʻē aʻe, inā hiki ke hoʻololi ʻia nā mea palaki, ʻōpala a me nā mea hoʻopaʻa metala, e ʻoi aku ka nui o ka noi kūloko makahiki no nā mea hoʻopaʻa graphite hoʻonui.
I ka ʻoihana kaʻa, pono kēlā me kēia kaʻa kaʻa poʻo poʻo, ka ea a me ka exhaust port gasket e pili ana i 2 ~ 10kg o ka graphite i hoʻonui ʻia, a ʻo kēlā me kēia kaʻa 10,000 pono 20 ~ 100 tons o ka graphite hoʻonui. Ua komo ka ʻoihana kaʻa o Kina i kahi wā o ka ulu wikiwiki ʻana. No laila, ʻo ke koi makahiki o koʻu ʻāina no ka hoʻonui ʻia ʻana o nā mea hoʻopaʻa graphite sealing, ʻoi loa ka pahuhopu.
