Kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi.He moʻolelo lōʻihi ko ke kanaka i ka hoʻohana ʻana i nā crucibles graphite.Ua hoʻohana ka poʻe mua loa i ka graphite maoli (flaky graphite a me ka lepo graphite) a me ka pālolo, slag a one paha e hui i loko o nā blanks, a ua hoʻohana ʻia nā kaʻina hana ipu lepo e hana i nā kīʻaha graphite no ka hoʻoheheʻe ʻana i nā metala (ke keleawe, hao, kila, etc.).Loaʻa i ka graphite crucible ka ikaika mechanical kiʻekiʻe, refractoriness, thermal conductivity, hiki ke kū i ka hoʻoheheʻe ʻana he nui a hiki ke pale i ka erosion o ka hopena wela kiʻekiʻe.Hiki i ka Graphite crucible ke hoʻoheheʻe i ka hao malleable, ke kila kila, ke keleawe keleawe, ka zinc alloy, ke keleawe solder, etc. Me ka hoʻomohala ʻana o ka ʻoihana hou, hoʻohana nā ʻoihana metala like ʻole i nā umu uila e honi i nā metala like ʻole, no laila ka hoʻohana ʻana i nā crucibles graphite me ka graphite maoli e like me ua kapu kekahi mea.Eia nō naʻe, hoʻomau ka hoʻohana ʻana o nā mea hoʻoheheʻe ʻoihana liʻiliʻi i kēia ʻano graphite crucible.
Mai ka hiki ʻana mai o ka graphite artificial i ka hopena o ke kenekulia 19, ua hana nā kānaka i ka graphite artificial i loko o nā crucibles graphite.ʻO ka hoʻomohala ʻana a me ka hana ʻana o ka graphite maʻemaʻe kiʻekiʻe, graphite ikaika kiʻekiʻe, kalapona aniani, a me nā mea ʻē aʻe, nā graphite crucibles i hana ʻia i kēia mau mea e hoʻomāhuahua i ka hoʻohana ʻana o ka graphite crucibles. ka hoʻomaʻemaʻe ʻana i nā metala makamae e like me ke gula a me ke kālā., Atomika ikehu uranium hooheheeia, semiconductor mea kilikaki hookahi aniani, germanium hookahi kristal hana, a pili i ka like 'ole kemika ana.
Hoʻokaʻawale ʻia nā kīʻaha graphite i loko o nā kīʻaha graphite maoli, nā kīʻaha graphite i hana ʻia e ke kanaka, nā kīʻaha graphite maʻemaʻe kiʻekiʻe, nā pahu kalapona vitreous, a me nā mea ʻē aʻe e like me kā lākou waiwai waiwai.E like me ke kumu, aia nā kīʻaha kila, nā kīʻaha keleawe, nā kīʻaha gula, a me nā kīʻaha analytical.

Nā hiʻohiʻona
Ua hōʻea a ʻoi aku paha ka pae o ka ʻenehana hana o nā crucibles graphite home.Loaʻa i nā crucibles graphite home kiʻekiʻe nā ʻano penei:
1. ʻO ke kiʻekiʻe kiʻekiʻe o nā crucibles graphite e loaʻa i nā crucibles ka maikaʻi loa o ka wela, a ʻoi aku ka maikaʻi o kāna conductivity wela ma mua o nā crucibles i lawe ʻia mai.;Kiʻi kiʻi kiʻi kiʻi.
2. Loaʻa i ka graphite crucible kahi papa glaze kūikawā a me nā mea hoʻoheheʻe paʻa, kahi e hoʻomaikaʻi nui ai i ka pale ʻana i ka corrosion o ka huahana a hoʻolōʻihi i kona ola lawelawe.
3. ʻO nā mea graphite i loko o ka graphite crucible he graphite maoli nō me ka thermal conductivity maikaʻi loa.Ma hope o ka wela o ka graphite crucible, ʻaʻole pono e kau koke ʻia ma luna o ka pākaukau metala anu i pale ʻole ʻia mai ka pohā ma muli o ka hoʻomaloʻo wikiwiki ʻana.

Ka malama ana
1. ʻO ka helu kikoʻī o ka crucible ka mana o ke keleawe (kg)
2. Pono e mālama ʻia ka graphite crucible ma kahi maloʻo a i ʻole ma kahi lāʻau lāʻau ke mālama ʻia.
3. E mālama pono i ka lawe ʻana, a pāpā loa ʻia ke hāʻule a haʻalulu.
4. Ma mua o ka hoʻohana ʻana, pono e kālua ʻia e ka mea hoʻomaloʻo a i ʻole ka umu, a hoʻonui mālie ʻia ka mahana i 500 ° C.
5. Pono e waiho ʻia ka ipuhao ma lalo o ka ʻili o ka waha o ka umu ahi e pale ai i ka uhi ʻana o ka umu ahi mai ke kau ʻana i ka waha o luna o ka ipu.
6. Pono ka hoʻohui ʻana i nā mea waiwai ma muli o ka nui o ka hoʻoheheʻe ʻana o ka crucible.Mai hoʻohui i nā mea he nui a pale i ka hoʻoomi ʻia ʻana o ka crucible.
7. 'O ka puka o waho o ka umu ahi a me ke ko'i ku'i e kulike me ke 'ano o ka ipuhao.ʻO ka ʻaoʻao waena o ka puʻupuʻu e pale i ka pōʻino o ka crucible e ka ikaika.
8. I ka huki ʻana i ka pā i hoʻoheheʻe ʻia a me ka coke ma nā paia o loko a me waho o ka ipu hao, e paʻi iā ia i mea e pale ai i ka pōʻino o ke kīʻaha.
9. Pono e mālama ʻia kahi mamao kūpono ma waena o ka ipuhao a me ka paia o ka umu ahi, a e kau ʻia ke kīwī i waenakonu o ka umu.
10. ʻO ka hoʻohana kūpono ʻana i nā mea kōkua a me nā mea hoʻohui e hoʻemi i ke ola lawelawe o ka crucible.
11. I ka wā e hoʻohana ai, ʻo ka hoʻohuli ʻana i ka crucible i hoʻokahi manawa i ka hebedoma hiki ke hoʻolōʻihi i ke ola lawelawe o ka crucible.
12. E pale aku i ka lapalapa ahi ikaika mai ka pulupulu pono ana i ka aoao a me ka puu lalo o ka ipuhao.
