Nānā o nā ʻano hao hao

Ka hao keʻokeʻo: E like me ke kō a mākou i hoʻokomo ai i ke kī, hemo loa ke kalapona i ka hao wai. Inā ʻaʻole hiki ke hoʻokaʻawale ʻia kēia kalapona i hoʻoheheʻe ʻia i loko o ka wai mai ka hao wai i ka wā e paʻa ai ka hao, akā e hoʻoheheʻe loa ʻia i loko o ka hale, kapa mākou i ke ʻano hopena o ka hao keʻokeʻo. Ua kapa ʻia ka hao hao keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo ke haʻihaʻi.

Ka hao hao hina: ʻOiai e paʻa ana ka hao hoʻoheheʻe wai, hiki ke puka mai ke kalapona i hoʻoheheʻe ʻia i loko o ka metala wai, e like me ke kō i loko o ke kī, ma ke ʻano he māhele kaʻawale i ka wā paʻa. Ke nānā mākou i kēlā ʻano hana ma lalo o ka microscope, ʻike mākou ua hoʻoheheʻe ʻia ke kalapona i kahi hale ʻokoʻa i ʻike ʻia e ka maka ʻōlohelohe, ma ke ʻano o ka graphite. Kapa mākou i kēia ʻano hao he hao hina hina, no ka mea, i ka wā i haki ai kēia ʻano, kahi i ʻike ʻia ai ke kalapona i loko o nā lamellae, ʻo ia hoʻi, ma nā papa, puka mai kahi kala ʻeleʻele a hina.

ʻO ka hao hao ʻikea: ʻO nā hao keʻokeʻo a mākou i ʻōlelo ai ma luna aʻe nei i loko o nā kūlana hoʻomaha wikiwiki, ʻoiai ke ʻike ʻia nā hao hina hina i nā kūlana hoʻomaha mālie. Inā kū like ka hoʻoluʻu ʻana o ka ʻāpana i ninini ʻia me kahi ākea kahi e hele ai ka hoʻololi ʻana mai ke keʻokeʻo i ka hina, hiki ke ʻike ʻia ke ʻike pū ʻia nā hale hina a me ke keʻokeʻo. Kapa mākou i kēia mau hao hao he ʻōniʻoniʻo no ka mea ke wāwahi mākou i kēlā ʻāpana, ʻike ʻia nā mokupuni hina ma ke ʻano keʻokeʻo.

ʻO ka hao hoʻoheheʻe ʻia: Paʻa maoli kēia ʻano hao e like me ka hao keʻokeʻo. I nā huaʻōlelo ʻē aʻe, ua hōʻoia ʻia ka paʻa ʻana o ka hao i hoʻoheheʻe ʻia ke kalapona i loko o ka hale. A laila, hoʻoheheʻe ʻia ka hao keʻokeʻo paʻa i ka hoʻomaʻamaʻa wela i hoʻokaʻawale ʻia ke kalapona i hoʻoheheʻe ʻia i loko o ka hale. Ma hope o kēia hoʻomaʻamaʻa wela, ʻike mākou e puka mai ana ke kalapona ma ke ʻano he mau pōʻai like ʻole, hui pū ʻia.

Ma waho aʻe o kēia hoʻokaʻawale ʻana, inā hiki i ke kalapona ke hoʻokaʻawale mai ka hale ma muli o ka paʻa ʻana (e like me ka hao hina hina), hiki iā mākou ke hana i kahi hoʻokaʻawale ʻē aʻe ma ka nānā ʻana i nā waiwai kūpono o ka graphite i loaʻa.

Ka hao hina (lamellar graphite) : Inā ua paʻa ke kalapona i mea e ulu aʻe ai ka papa graphite e like me nā lau kāpeti, e pili ana mākou i nā hao hao e like me ka hao hina a i ʻole ka lamellar graphite. Hiki iā mākou ke hoʻopaʻa i kēia ʻano, i hana ʻia i loko o nā alloys kahi i kiʻekiʻe ai ka oxygen a me ka sulfur, me ka ʻole o ka hōʻike ʻana i ke ʻano o ka emi ʻana ma muli o kāna conductivity thermal kiʻekiʻe.

Ka hao graphite pōʻai: E like me ka inoa, ʻike mākou i loko o kēia hale, ʻike ʻia ke kalapona ma ke ʻano he pōpō graphite pōʻai. I mea e hoʻoheheʻe ʻia ai ka graphite i loko o kahi ʻano spherical ma mua o kahi ʻano lamellar, pono e hoʻemi ʻia ka oxygen a me ka sulfur i loko o ka wai ma lalo o kahi pae. ʻO ia ke kumu i ka hana ʻana i ka hao graphite spheroidal, mālama mākou i ka metala wai me ka magnesium, hiki ke hana wikiwiki me ka oxygen a me ka sulfur, a laila ninini ʻia i loko o nā mole.

Vermicular graphite hao hao: Inā ʻaʻole lawa ka lāʻau magnesium i ka wā o ka hana ʻana i ka hao graphite graphite a ʻaʻole hiki ke hoʻopololei piha ʻia ka graphite, hiki ke puka mai kēia ʻano graphite, a mākou i kapa ai he vermicular (a i ʻole compact). ʻO ka graphite vermicular, kahi ʻano hoʻololi ma waena o nā ʻano lamellar a me nā ʻano graphite spheroidal, ʻaʻole wale ka hāʻawi ʻana i ka hao hao me nā waiwai mechanical kiʻekiʻe o ka graphite spheroidal, akā e hōʻemi pū ana hoʻi i ke ʻano shrinkage mahalo i kāna conductivity thermal kiʻekiʻe. ʻO kēia hoʻolālā, i manaʻo ʻia he kuhi hewa i ka hana ʻana i ka hao graphite spheroidal, ua hoʻolei ʻia e nā kumu kumu he nui ma muli o nā pono i ʻōlelo ʻia ma luna.
