Me ka wikiwiki o ka hoʻomohala ʻana o ka ʻoihana o ka honua, ua manaʻo ʻia ka pauka graphite ʻo ia kekahi o nā mea maka mineral koʻikoʻi o ka ʻoihana ma ka home a ma waho. ʻOi loa i nā makahiki i hala iho nei, me ka holomua o ka ʻepekema a me ka ʻenehana, ua hoʻokani ka graphite i kahi kuleana koʻikoʻi ma nā ʻoihana like ʻole.
I ka ʻoihana, ua hoʻokaʻawale ʻia nā ʻāpana graphite i ʻelua mau māhele nui: nā ʻāpana graphite crystalline a me nā ʻāpana graphite crystalline paʻa. Hiki ke hoʻokaʻawale hou ʻia nā ʻāpana graphite crystalline i ʻelua ʻano: flaky a me dense.
ʻO nā ʻāpana graphite ma Kina he ʻano crystalline flaky, a ukali ʻia e ke ʻano cryptocrystalline. Loaʻa wale ka graphite crystalline dense i loko o kekahi mau waihona e like me Tokbula ma Xinjiang a he liʻiliʻi ka waiwai ʻoihana.
Mālama ka graphite ʻoihana i nā waiwai kemika mua o ka graphite flake, ʻo ia hoʻi ke kūpaʻa ʻakika, ke kūpaʻa ʻana i ka pala a me nā waiwai kino, a me ke kūpaʻa ʻana i nā mahana kiʻekiʻe a haʻahaʻa. ʻOi aku kona ikaika compressive ma mua o 800kg/cm², a kūpaʻa ia i ka oxidation. Hoʻemi ia i ka 1% o kona kaumaha i ka ea 450℃ a he 15-50% ka rebound rate. Loaʻa iā ia kahi hana lubrication ponoʻī ikaika loa o ka pauka graphite. No laila, ua hoʻohana nui ʻia ka graphite i ka metallurgy, ka ʻenekinia kemika, nā petrochemicals, ka physics ikehu kiʻekiʻe, ka aerospace, nā mea uila a me nā ʻoihana ʻē aʻe.
Ma ka hoʻohana ʻana i nā waiwai o ka graphite, ua hana akamai nā kānaka i nā ʻano huahana like ʻole e like me nā pono o ka ʻenekinia, e like me ka graphite maʻemaʻe kiʻekiʻe, ka graphite palupalu, ka graphite hui pū ʻia, a pēlā aku. No ka hoʻonui ʻana i kāna hana, ua hui pū ʻia ka graphite me nā olonā, nā uea metala graphite, nā ʻupena metala a me nā papa hana metala e hana i ka pauka graphite composite graphite, kahi e hoʻonui nui ai i kona ikaika a me ka elasticity.
Hoʻopili ʻia ka graphite composite i ke anu a i ʻole ka hoʻopaʻa wela ʻia me nā resins, nā rubbers synthetic a me nā plastics. Aia pū kekahi graphite wai a me ka graphite semi-wai.
He kuleana koʻikoʻi ko Graphite ma nā ʻano kahua like ʻole, e like me ke sila ʻana, ke kūpaʻa wela, ke kūpaʻa ʻana i ka pala, ka conductivity uila, ka mālama ʻana i ka wela, ke kūpaʻa ʻana i ke kaomi, ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa ʻana i ka oxidation, kahi mea i huki i ka manaʻo nui mai nā loea ma ka home a ma waho. ʻOiaʻiʻo, ke komo mālie nei hoʻi ka graphite i nā lako keʻena hou. No ka laʻana, hoʻohana kahi hale hana lako waihona ma ka moku ʻo Jiangxi i ka graphite e hoʻonui a hana iā ia i mau pepa poepoe pale pepeke me kahi hiki ke hoʻopili i nā lāʻau lapaʻau a hiki ke mālama i ko lākou pono no hoʻokahi makahiki.
Ma muli o ke koina hoʻonui liʻiliʻi o ka graphite a me kona hiki ke kū i nā loli wikiwiki o ka mahana, hiki ke hoʻohana ʻia e like me ka mold no nā mea aniani. Ma hope o ka hoʻohana ʻana i ka graphite, loaʻa i nā mea hoʻoheheʻe i loaʻa mai nā metala ferrous nā ana pololei, nā ʻili laumania, a me nā helu hua kiʻekiʻe. Hiki ke hoʻohana ʻia me ka ʻole a me ka hana iki wale nō, no laila e mālama ana i ka nui o ka metala. I ka hana ʻana i nā kaʻina hana metallurgy pauka e like me nā alloys paʻakikī, nā waʻa a me nā kīʻaha no ka sintering pale-kaomi i hana pinepine ʻia me nā mea graphite. Eia kekahi, hiki ke hoʻohana ʻia ka graphite ma ke ʻano he mau papa a me nā kumu insulation graphite hoʻoheheʻe vacuum, a me nā ʻāpana e like me nā paipu umu pale wela kiʻekiʻe, nā koʻokoʻo, nā papa, a me nā keʻena.
