Nā hiʻohiʻona o ka hoʻohana
Loaʻa i ka clay graphite crucible ka nui o ka hoʻohana ʻana a me ka hana maikaʻi loa, kikoʻī:
- Ka hoʻohana ākea: Inā i loko o ka ʻimi noiʻi ʻana, alchemy, a i ʻole nā mea hoʻokolohua kemika ʻē aʻe, ua kūpono ka clay graphite crucible no nā hana wela kiʻekiʻe a he koho kūpono.
- ʻO ke ola lawelawe lōʻihi: Ma muli o kāna mea ʻoi aku ka maikaʻi, hiki ke hoʻohana pinepine ʻia nā crucibles graphite pālolo i mau haneli mau manawa, e hōʻemi nui ana i ke alapine a me ke kumukūʻai o ke pani.
- Mālama maʻalahi a maʻalahi hoʻi: He maʻalahi a maʻalahi ka hoʻomaʻemaʻe ʻana o ka crucible surface, a maʻalahi loa ka mālama ʻana i kēlā me kēia lā, e hāʻawi ana i nā mea hoʻohana me ka maʻalahi.
Hoʻomalu
I mea e hōʻoia ai i ka hana maikaʻi loa a me ka lōʻihi o ka lawelawe ʻana o ka clay graphite crucible, pono e noʻonoʻo ʻia nā mea aʻe i ka wā e hoʻohana ai:
- Hōʻalo i nā kaiapuni oxidizing: ʻAʻole ʻōlelo ʻia e hoʻohana i nā crucibles me nā mea, nā mea a i ʻole nā mea hoʻonā i maʻalahi ke hoʻoheheʻe ʻia e pale i ka pōʻino oxidative.
- ʻO ke koho kūpono o ka hiki: I ka wā e hoʻohana ai, pono ʻoe e koho i kahi mana crucible kūpono a mālama i ka hana o ka wela e pale aku i ka pōʻino o ka crucible ma muli o ka piʻi koke ʻana o ka wela.
- Hōʻalo i ka hoʻohana ʻana i ka wela kiʻekiʻe: I nā hopena corrosive e like me ka waika ikaika a me ka alkali ikaika, pono e pale ʻia ka hoʻohana ʻana i ka wela kiʻekiʻe i ka wā e hiki ai ke pale aku i ka paʻa o ka crucible.
I ka hopena
I ka hōʻuluʻulu manaʻo, ua lilo ka pālolo graphite crucible i mea waiwai nui no nā hana wela kiʻekiʻe i nā laboratories a me nā ʻoihana ʻenehana ma muli o kona kūpaʻa kiʻekiʻe kiʻekiʻe, ikaika kiʻekiʻe, a me ke kūpaʻa corrosion. Hiki i ka hoʻohana a me ka mālama pono ke hōʻoia i kona ola lōʻihi a me ka hana paʻa. Hōʻike ʻo Clay graphite crucible i nā manaʻo noiʻi ākea i ka hoʻoheheʻe ʻana, ka ʻoihana kemika, ka hale hana a me nā māla ʻē aʻe, a he koho kūpono ia no kāu hoʻokolohua kiʻekiʻe a me ka hana ʻana.
