Daimana a megraphiteʻelua mau ʻano kalapona like ʻole i hopu i ko mākou mau manaʻo no nā kenekulia.Ma waho aʻe o kā lākou hiʻohiʻona nani a me nā noi ʻenehana like ʻole, aia kēia mau mea i nā waiwai hoihoi e hoʻokaʻawale iā lākou mai kekahi i kekahi.ʻO kekahi o kēia mau waiwai ʻo ko lākou wahi heheʻe.Ma kēia pou blog, mākou'E komo i loko o ka honua hoihoi o ke daimana a me ka graphite, e ʻimi ana i nā mea e hoʻohuli ai i ko lākou helu heheʻe a hōʻike i kā lākou mau waiwai kūʻokoʻa.
Ka helu hehee daimana:
Ua kapa pinepine ʻia nā daimana ʻo ke aliʻi o nā pōhaku makamae a ʻike ʻia no ko lākou paʻakikī a me ka nani nani.Eia nō naʻe, i ka hiki ʻana mai i nā helu heheʻe, hōʻike nā daimana i ke kūʻokoʻa wela.E like me kona ʻōlinolino hoʻohiwahiwa, he kuleana koʻikoʻi ka hana molekala daimana i ka hoʻoholo ʻana i kona wahi heheʻe kiʻekiʻe.
Aia i loko o ka ho'olālā lattice o Daimana nā 'ātoma kalapona i ho'onohonoho 'ia ma ke kumu tetrahedral.ʻAʻole hiki ke haki ʻia kēia pūnaewele ikaika ʻekolu-dimensional, hāʻawi i nā daimana i kahi helu heheʻe kiʻekiʻe.ʻO ka daimana ka mea hiki ke pale i ka wela, me kahi helu heheʻe ma kahi o 3,550 degere Celsius (6,372 degere Fahrenheit).Me kēia helu hoʻoheheʻe, hiki i ke daimana ke kū i nā mahana wela, e kūpono ia no nā ʻano hana ʻoihana like ʻole, e like me nā mea hana ʻoki a me nā wahi wela kiʻekiʻe.
Ka helu hehee o ka graphite:
He ʻokoʻa loa ka graphite me ke daimana, he ʻano molekala ʻokoʻa loa ka graphite, e hopena i kahi helu heheʻe haʻahaʻa loa.Aia ka Graphite i nā ʻāpana kalapona i hoʻonohonoho ʻia i ke ʻano hexagonal, e hana ana i kahi pūʻulu o nā flakes i hoʻopaʻa ʻia.Hoʻopaʻa pū ʻia nā lau e nā ikaika intermolecular nāwaliwali, e maʻalahi ai ka hoʻopau ʻana i ka hana lattice ke hoʻomehana ʻia.
Hāʻawi ka hana molekala o Graphite iā ia i ka hoʻoili uila maikaʻi loa a loaʻa iā ia nā waiwai lubricating ma muli o ke ʻano paheʻe o kona mau papa.Eia naʻe, he haʻahaʻa ko ka graphite a me ke daimana.He helu hehee ko ka graphite ma kahi o 3,500 degere Celsius (6,332 degere Fahrenheit) a he haʻahaʻa haʻahaʻa kona pale ʻana me ka daimana.
No ke aha he mea nui kēia ʻokoʻa:
He mea nui ka hoʻomaopopo ʻana i nā helu heheʻe o ke daimana a me ka graphite no kekahi mau kumu.Mai kahi kuanaʻike ʻepekema, hōʻike ia e hōʻike ana ke kalapona i nā ʻano waiwai kino e pili ana i kona hoʻonohonoho ʻana ma ka pae molekala.Eia hou, hiki i ka ʻoihana ke hoʻohana i kēia ʻike e koho i ke ʻano kalapona kūpono no nā noi kikoʻī, a laila e hoʻonui ai i ka pono a me ka hana.
ʻOiai ʻo ka daimana a me ka graphite he mau wahi heheʻe kokoke loa, ʻo kā lākou mau ʻano molekala like ʻole a me nā waiwai hopena e hāʻawi i nā mea like ʻole no ka hoʻohana ʻana.ʻO ka helu heheʻe kiʻekiʻe o Diamond he mea waiwai ia i nā kaiapuni paʻakikī, ʻoiai ʻo ka helu heheʻe haʻahaʻa o ka graphite e hoʻonui i kona kūpono i nā noi e koi ana i ka conductivity uila a me ka lubrication.
In hopena:
ʻO ka hōʻuluʻulu manaʻo, ʻo nā helu heheʻe o ke daimana a me ka graphite kekahi mea hoihoi o kēia mau ʻano kalapona kupaianaha.ʻIke ʻia ka ʻokoʻa no ka mea he kiʻekiʻe loa ka helu heheʻe o ke daimana a ʻo ka graphite he wahi heheʻe haʻahaʻa.ʻO nā ʻano molekala like ʻole o kēia mau hoahānau kalaponaʻhāʻawi iā lākou i nā waiwai kūʻokoʻa a hoʻolilo iā lākou i kumu waiwai no nā ʻoihana like ʻole.Ma ka hoʻomaopopo ʻana i nā nuances ma hope o ko lākou mau wahi heheʻe, hiki iā mākou ke aʻo hou aʻe e pili ana i ka honua kupaianaha o nā daimana a me ka graphite, e hoʻonui mau i ko mākou mahalo no ko lākou mau ʻano kūʻokoʻa.
