Nā Kūlana Kūʻai

Nā Kūlana KūʻaiHāʻawi i kahi nui o nā waiwai e hana ai iā lākou i ke koho kiʻekiʻe no nā noi kiʻekiʻe no nā noi kiʻekiʻe Eia nā mea nui o nā mea waiwai a me nā kiko'ī e wehewehe ana i ka hana o kēia mau mea holo.

1. Ka HōʻaʻO Kokua
   • Nā Kūlana KūʻaiHōʻike i ka hanaʻino maikaʻi loa, e hōʻoia ana i ka hoʻokaʻawaleʻana i ka wela wela. Hōʻemi kēia waiwai i ka wela nā wahi wela a e hoʻopau ai, e hana pono iā lākou i mau mea ulu me nā gula gula gula ma ke gula gula gula gula mestalsing bold, aluminua.
   • Hiki i ke ola ke hele i nā waiwai o ka 100 W / M / M · K,ʻoi aku ka nui o nā mea kūʻai aku.
2. Ke kū'ēʻana i ke kūlana kiʻekiʻe
   • Nā Kūlana Kūʻaihiki ke hiki i nā kiʻekiʻe kiʻekiʻe kiʻekiʻe loa, a hiki i ka 1700° Ci loko o nāʻano hana a iʻole nā ​​kūlana hoʻomaha. Hiki i kēia ke mālama iā lākou e mālama i ka kūpaʻa hoʻonohonoho i nā mea e noi ana i nā wahi eʻole ai me ka hoʻowahāwahāʻole.
   • Ke hoʻomau nei kēia mau crucables a me ke kū'ēʻana i ka deformation ma lalo o ka wela wela.
3. ʻO ka maʻalahi o ka uku haʻahaʻa o ka hoʻonuiʻana
   • Loaʻa nā mea kiʻi kiʻi kiʻiʻO ka maʻalahi o ka uku haʻahaʻa o ka hoʻonuiʻana(Ma ka haʻahaʻa e like me 4.9 x 10 ^ -6 / ° C), e hōʻemi ana i ka hopena o ka hana wikiwiki a iʻole ke hoʻololiʻana i nā loli wikiwiki.
   • Hoʻokomoʻia kēia hiʻohiʻona i nā cruccibles cricables i kūpono no nā kaʻina hana e pili ana i ka hoʻopili pinepineʻana i nāʻano hana hou a me ka hoʻomahaʻana.
4. Ke kū'ē neiʻo Corrosionion
   • ʻO ka kiʻi kiʻi kiʻi kiʻi a me nā makanaʻO ke kū'ēʻana i ka hapa nui o nā Adick, Alkalis, a me nā mea hoʻoponopono'ē aʻe, nui loa i ka hōʻemiʻana a iʻole nā ​​mea hanaʻole. Hana kēia i nā kiʻi kiʻi kiʻi kiʻi kūpono no nā wahi e hiki ai i nā wahi kemika i loko o keʻano metala a iʻole ka hōʻoluʻolu.
   • Hiki ke hoʻonui houʻia ka paleʻana o ka waiwai i ka oxidation e nā lole a iʻole nā ​​hana kūikawā, e hōʻoia ana i ke ola lawelawe uku.
5. Mea kūʻai uila
   • E like me ka mea hana maikaʻi o ka uila, he kūpono nā mea kiʻi kiʻi no nā noi i hoʻopaʻaʻia. Hiki i keʻano o ke kālā uila kiʻekiʻe e hoʻopili pono me nā'ōnaehana indiction insouction, e hōʻoia ana i ka rapid a me keʻano hana.
   • He mea maikaʻi loa kēia waiwai i nā hana e koi aiʻO ke kālā i nā mea mater heter, ke hoʻonuiʻana i ka hana hana hana i nāʻoihana e like me nā hana e loaʻa ai ka hana a me ka metallirgy.
6. Maʻemaʻe a me nā mea hoʻohui
   • ʻO ke kelepona kiʻekiʻe kiʻekiʻe o ka Carbon kiʻekiʻe(a hiki i 99.9% maʻemaʻe) he mea nui no nā noi e pono ai e paleʻia, e like me ka hanaʻana i nā metala koʻikoʻi.
   • Silchion Carbide Skide CriciblesHoʻohui i nā waiwai o nā kiʻi aʻelua, Kāleʻa Silima, e hāʻawiʻia e ka mana mīkini, a me ke kāohiʻana, a me kahi kūlana kiʻekiʻe loa.
7. Ka lōʻihi a me ka lōʻihi
   • Ua paʻiʻiaʻo ISOSTATATITITITITED CRICCLESua hanaʻia e loaʻa i nāʻano kūpono a me ka ikaika, e hopena ana i nāʻano lōʻihi a me nā hana hōʻemi. ʻOi aku kēia mau crucables i nā mea e hoʻohuliʻia i ka erosion a me nā hana hana.

8. Nā Kūlana Kūlana:

   • Carbon (c): 20-30%
   • Silicon caride (sic): 50-60%
   • ALUNE (Al2O3): 3-5%
   • Maahua: 3-5%
9. Nā hōʻailona maʻamau a me nāʻano
   • Loaʻa kā mākou kiʻi kiʻi kiʻi kiʻi kiʻi ma nāʻano nui o nā nui a me nā hoʻonohonoho. Mainā kiʻi kiʻi kiʻi liʻiliʻi(kūpono no ka ho'āʻoʻana o ka lab-squar i ka hana nui) i nā mea he nui i hoʻolālāʻia no ka smallrial-still smallning
   • Nā Kūlana Kūʻaia me nā mea kanu mepohahiki ke hana pūʻia i nā koi o nā mea kūʻai aku, e hōʻoia i ka maʻalahi a me ka maikaʻi a me ka hana kūpono i ka hanaʻana i ke metala.
