Hoʻokaʻawale ʻia ka hoʻoheheʻe metala makamae i ka hoʻoheheʻe mua a me ka hoʻomaʻemaʻe.ʻO ka hoʻomaʻemaʻe ʻana, ʻo ia ka loaʻa ʻana o ka metala makamae maʻemaʻe kiʻekiʻe ma o ka hoʻoheheʻe ʻana i nā metala maʻemaʻe haʻahaʻa, kahi e pono ai nā crucibles graphite me ka maʻemaʻe kiʻekiʻe, kiʻekiʻe puʻupuʻu nui, haʻahaʻa porosity a me ka ikaika maikaʻi.
ʻO nā mea hana graphite no nā mea hoʻokolohua i hanaʻia i keʻano kiʻekiʻe, ka ikaika kiʻekiʻe, ka maʻemaʻe kiʻekiʻe, a me ka graphite kiʻekiʻe, me ka'ōniʻoniʻo a me nā pores.Loaʻa iā lākou nā hiʻohiʻona o ka conductivity thermal like ʻole, ka hoʻomehana wikiwiki, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa ʻana i ka corrosion alkali;Eia kekahi, hiki ke hoʻohana ʻia ka hoʻomaʻamaʻa ʻana i ka uhi kūikawā.Ma hope o ka mālama ʻana i ka ʻili, ma lalo o ka hoʻomehana wela kiʻekiʻe no ka wā lōʻihi, ʻaʻohe hanana o ka pauka hoʻokahe ʻana, ka ʻohi ʻana, ka pōʻino, a me ka oxidation.Hiki iā ia ke pale i nā waikawa ikaika a me nā alkalis, lōʻihi, nani, a ʻaʻole ʻōpala.

I ka manawa hea e loaʻa ai iaʻu ke kumukūʻai?
Hāʻawi pinepine mākou i kahi ʻōlelo i loko o 24 mau hola ma hope o ka loaʻa ʻana o kāu mau koi kikoʻī, e like me ka nui, ka nui, etc.
Inā he kauoha wikiwiki, hiki iā ʻoe ke kelepona pololei iā mākou.
Hāʻawi ʻoe i nā laʻana?
ʻAe, aia nā laʻana i loaʻa iā ʻoe e nānā i kā mākou maikaʻi.
ʻO ka manawa hāʻawi hāʻawi ma kahi o 3-10 mau lā.
He aha ke kaʻina hoʻopuka no ka hana nui?
Hoʻokumu ʻia ka pōʻai hoʻopuka ma ka nui a ma kahi o 7-12 mau lā.No nā huahana graphite, pono ia ma kahi o 15-20 mau lā hana e loaʻa ai kahi laikini mea hoʻohana pālua.
