Nā kīʻahahe mau mea hana koʻikoʻi ma nā ʻoihana like ʻole no ka lawelawe ʻana i nā kaʻina hoʻoheheʻe a me ka hoʻoheheʻe ʻana.He ipu ia e hiki ke pale aku i ka wela kiʻekiʻe a hoʻohana ʻia e hoʻopaʻa i nā mea a me ka wela iā lākou a hiki i ko lākou helu heheʻe.Hoʻohana ʻia nā ʻano crucibles ma muli o nā koi kikoʻī o ka mea i hoʻoheheʻe ʻia a hoʻoheheʻe ʻia.Ma kēia pou blog, e ʻimi mākou i nā ʻano crucibles like ʻole a me kā lākou noi.
1. Ka hao hao:
E hoʻohana i ka hao i ka hoʻoheheʻe ʻana i nā mea alkaline ikaika e like me NaOH.Eia nō naʻe, ʻaʻole i hoʻohana nui ʻia ma muli o nā pilikia e like me ka maʻalahi o ka ʻōpala a me ka oxidation.I ka nui o nā noi e pili ana i nā mea alkaline, ʻo nā crucibles metala inert ka mea i koho ʻia.
2. Hoolei hao.
Hana ʻia nā kīʻaha hao mai ka hao puaʻa a ua ʻike ʻia no ko lākou lōʻihi.Hoʻohana ʻia ia e hoʻoheheʻe i nā ʻāpana metala like ʻole me ka aluminika, zinc, lead, tin a me nā alloys antimony.Ke hoʻohālikelike ʻia me nā kīʻaha hao, ʻoi aku ka lōʻihi o nā kuʻi hao i hoʻolei ʻia a hiki ke kū i nā wela kiʻekiʻe e pono ai e hoʻoheheʻe i kēia mau ala.
3. ʻO ke kīʻaha Quartz:
Hoʻohana maʻamau ʻia nā crucibles quartz i ka ʻoihana semiconductor a he mea nui ia no ka hana ʻana i nā kaapuni hoʻohui nui.Hiki i kēia mau crucibles ke kū i nā mahana a hiki i 1650 degere a loaʻa i nā mana maʻemaʻe a opaque.Hoʻohana ʻia ka pahu quartz translucent ma ke ʻano arc, i hoʻohana ʻia no ka huki ʻana i ka silika aniani hoʻokahi.Loaʻa iā ia nā mea maikaʻi o ka maʻemaʻe kiʻekiʻe, ke kūpaʻa wela ikaika, ka nui nui, ka pololei kiʻekiʻe, ka hana insulation thermal maikaʻi, ka mālama ʻana i ka ikehu, a me ka maikaʻi paʻa.Eia naʻe, pono e mālama ʻia no ka mea he palupalu ka quartz a hiki ke haki.
4. ʻO ke kīʻaha porcelain:
Kaulana ʻia nā crucibles seramika no ko lākou kūpaʻa ʻana a me ka hiki ke kūʻai aku.Eia nō naʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia nā mea alkaline e like me NaOH, Na2O2, Na2CO3, a pēlā aku, no ka mea, e hana lākou me ka porcelain a hoʻoulu i ka corrosion.Eia kekahi, ʻaʻole pono e hoʻopili ʻia nā crucibles porcelain me ka waika hydrofluoric.Ua kūpono lākou no ka hoʻohana ʻana i nā mahana ma kahi o 1200 degere.
5. Korundum crucible:
He kūpono loa ka corundum crucible no ka hoʻoheheʻe ʻana i nā laʻana me ka hoʻohana ʻana i nā mea alkaline nāwaliwali e like me ka anhydrous Na 2 CO 3 ma ke ʻano he flux.Eia nō naʻe, ʻaʻole kūpono lākou no ka hoʻoheheʻe ʻana i nā laʻana me ka hoʻohana ʻana i nā mea alkaline ikaika (e like me Na2O2, NaOH) a i ʻole nā mea ʻakika (e like me K2S2O7) e like me ka fluxes.
6. ʻO ke kīʻaha graphite:
Hoʻohana nui ʻia nā crucibles graphite i ka ʻoihana hoʻoheheʻe metala ma muli o kā lākou conductivity thermal maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe.He kūpono lākou no ka hoʻoheheʻe ʻana i nā metala like ʻole me ke keleawe, ke gula, ke kālā a me ke keleawe.
7. Silicon carbide crucible:
Ua ʻike ʻia nā crucibles Silicon carbide no ko lākou conductivity thermal kiʻekiʻe a me ke kūpaʻa kemika maikaʻi loa.Hoʻohana ʻia lākou i nā kaʻina hoʻoheheʻe a me ka hoʻoheheʻe ʻana e pili ana i nā noi wela kiʻekiʻe, e like me ka hana ʻana i nā seramika a me nā alloys.
Loaʻa i kēlā me kēia ʻano crucible kona pono ponoʻī a me nā noi.ʻO ke koho crucible e pili ana i nā mea e like me ka mea i hoʻoheheʻe ʻia a hoʻoheheʻe ʻia, ka pae wela i makemake ʻia a me ke kālā.Inā ʻoe e hoʻoheheʻe keleawe, hoʻoheheʻe metala, a i ʻole hoʻoheheʻe ʻia, ʻo ke koho ʻana i ka crucible kūpono he mea koʻikoʻi i ka hana kūleʻa a maikaʻi.
I ka hōʻuluʻulu manaʻo, pāʻani koʻikoʻi nā crucibles i nā ʻoihana like ʻole e pili ana i nā kaʻina hoʻoheheʻe a me ka hoʻoheheʻe ʻana.ʻO ka hoʻomaopopo ʻana i nā ʻano crucibles like ʻole i loaʻa a me kā lākou mau noi kikoʻī hiki ke kōkua i nā ʻoihana e hoʻoholo i ka ʻike e pili ana i ka crucible e hoʻohana ai e hoʻokō i kā lākou mau pono kikoʻī.ʻO ka hao hao, ka hao hao, ka quartz crucible, ka porcelain crucible, ka corundum crucible, ka graphite crucible a me ka silicon carbide crucible, loaʻa i kēlā me kēia ʻano kona pono ponoʻī a me nā palena.Ma ke koho ʻana i ka crucible kūpono, hiki i nā ʻoihana ke hoʻoikaika i kā lākou hana a hōʻoia i nā hopena kiʻekiʻe.
