ʻO ka pauka Graphite kahi ʻano mea pauka maikaʻi i hana ʻia me ke kalapona ma hope o ka pyrolysis a i ʻole carbonization kiʻekiʻe, a ʻo kāna mea nui he kalapona. ʻO ka pauka Graphite he ʻano papa ʻokoʻa, he ʻeleʻele hina a ʻeleʻele māmā paha. ʻO 12.011 kona kaumaha mole.
Hiki ke hōʻuluʻulu ʻia nā ʻano o ka pauka graphite penei:
1. Kiʻekiʻe conductivity a me thermal conductivity: graphite pauka mea he maikai conductive a me ka thermal conductivity mea, me kiʻekiʻe thermal conductivity a me ka conductivity. ʻO kēia ma muli o ka hoʻonohonoho paʻa ʻana a me ka hoʻonohonoho ʻana o nā ʻātoma kalapona i ka graphite, e maʻalahi ai i nā electrons a me ka wela ke hana.
2. ʻO ka inertness kemika maikaʻi: ʻO ka pauka graphite he paʻa kemika maikaʻi a me ka inertness ma lalo o nā kūlana maʻamau, a ʻaʻole e pane me ka nui o nā mea. ʻO ia hoʻi ke kumu i hoʻohana nui ʻia ai ka pauka graphite i nā kula o nā mea uila a me nā mea kemika, ka pale ʻana i ka corrosion kiʻekiʻe, etc.
3. Loaʻa iā ia kekahi ikaika mechanical: ke hoʻohālikelike ʻia me nā mea nano-mea ʻē aʻe, ʻoi aku ka kiʻekiʻe o ka hopena o ka graphite pauka, ke kūpaʻa extrusion a me ke kūʻē ʻana i ka māwae, hiki ke hoʻonui i nā waiwai mechanical o nā mea i kekahi ʻano.
He ʻokoʻa nā ʻano hoʻomākaukau o ka pauka graphite, a ʻo nā ʻano hana maʻamau penei:
1. Pyrolysis i ka wela kiʻekiʻe: wela i ka graphite maoli a i ʻole kemika synthesized graphite crystal i ka wela kiʻekiʻe (ma luna o 2000 ℃) e hoʻoheheʻe ʻia i ka pauka graphite.
2. ʻO ke ʻano carbonization kiʻekiʻe: loaʻa ka pauka graphite ma ka hopena kemika o ka graphite me nā mea maka me ka papa hana e like me ka graphite. Wahi a nā mea maka, hiki ke hoʻokaʻawale ʻia i nā ʻano hoʻomākaukau like ʻole, e like me ka deposition vapor chemical vapor, pyrolysis a me carbonization.
3. Nā Kūlana Mechanical: Ma o nā mīkini hana hoʻomaʻemaʻe a me kaʻikeʻana i nā hana a me nā kiʻi kūlohelohe a iʻole nā kiʻiʻoniʻoni a iʻole nā kiʻi kiʻiʻoniʻoni a iʻole nā kiʻi kiʻi kiʻi kiʻiʻia e loaʻa ai ka pauna kiʻi kiʻi.
Loaʻa i nā ʻano hoʻomākaukau like ʻole nā hopena like ʻole i ka maikaʻi, ka maʻemaʻe a me ka morphology o ka pauka graphite. Ma nā noi kūpono, pono e koho ʻia nā ʻano hoʻomākaukau kūpono e like me nā koi like ʻole.
1. Nā mea uila a me nā mea kemika: hiki ke hoʻomākaukau ʻia ka pauka graphite i loko o ka conductive a me ka thermal conductive polymer composites, i hoʻohana ʻia i loko o nā mea uila, nā pā, nā inika conductive a me nā māla ʻē aʻe. No ka laʻana, i nā mea electrode, hiki i ka pauka graphite ke hoʻonui i ka conductivity o ka mea, hoʻomaikaʻi i ka hana electrochemical o ka electrode, a hoʻonui i ke ola lawelawe o ka pā.
2. Nā mea hoʻopili: hiki ke hoʻohanaʻia ka pauka graphite no ka hoʻomākaukauʻana i nāʻaʻahu likeʻole, e like me ka pale anti-corrosion, thermal conductivity coating, electromagnetic shielding coating, a me nā mea'ē aʻe. me ka pauka graphite hiki ke hoʻomaikaʻi i ke kū'ē ultraviolet a me ka pale ʻana o nā mea.
3. Catalyst: Hiki ke hoʻohana ʻia ka pauka Graphite no ka hoʻomākaukau ʻana i ka catalyst, a hoʻohana nui ʻia i ka synthesis organik, hana kemika a me nā māla ʻē aʻe. No ka laʻana, i ka hydrogenation o ka aila meaʻai, graphite pauka ma hope o lapaʻau hiki ke hoʻohana 'ia e like me ka catalyst e hoʻomaikaʻi i ka reaction selectivity a me ka hua.
4. Nā mea hana ceramic: I ka hoʻomākaukau ʻana i nā mea seramika, hiki i ka pauka graphite ke hoʻomaikaʻi i kona ikaika mechanical a me nā waiwai ʻē aʻe ma o ka hoʻoikaika ʻana i ka hopena. ʻOi loa i nā cermets a me nā seramika porous, hoʻohana nui ʻia ka pauka graphite.
