Ua ʻoi aku ka nui o nā crucibles graphite home ma mua o nā mea i lawe ʻia mai: ʻoi aku ka maikaʻi o ka hana ʻana ma nā wahi ʻino

I nā makahiki i hala iho nei, ʻo ka ʻenehana hana o ka homegraphite cruciblesua holomua nui. ʻAʻole wale lākou i loaʻa i nā crucibles i lawe ʻia mai, akā i kekahi mau hihia ua ʻoi aku ma mua o lākou. Ma ka hoʻohana ʻana i nā ʻenehana hana hou a me ka ʻimi ʻana i nā mea waiwai kiʻekiʻe, hiki i nā crucibles graphite ke kū i nā kūlana koʻikoʻi me ka maikaʻi ʻole.

ʻO nā hiʻohiʻona nui o kēia mau crucibles graphite hou he mea pono e ʻike. ʻO ka mea mua, loaʻa iā lākou ka conductivity thermal kiʻekiʻe, me ka hoʻohaʻahaʻa nui ʻana i ka manawa hoʻoheheʻe, mahalo i ka hoʻohana ʻana i nā mea maka e like me ka graphite, nona ka conductivity thermal maikaʻi loa. ʻO kēia hoʻonui i ka pono ʻaʻole wale e mālama i ka manawa a me ka ikehu, akā hoʻonui pū i ka huahana ma nā ʻoihana.

Eia kekahi, ʻoi aku ka maikaʻi o kēia mau crucibles i ka wela wela a hiki ke kū i nā mahana a hiki i 1200 a 1600 ° C. He mea kūpono kēia ʻano maikaʻi no nā noi e koi ana i nā wela kiʻekiʻe, e like me nā hoʻolei metala a me nā foundries. ʻO ka hiki ke pale aku i kēlā mau wela wela me ka ʻole o ka hoʻokō ʻana i ka hana he mea hoʻololi pāʻani no nā kaʻina hana ʻoihana.

ʻO kekahi o nā mea kupanaha loa o kēia mau crucibles graphite ʻo ko lākou kūpaʻa maikaʻi loa. Hōʻike lākou i ke kūpaʻa nui a hiki i ke alo o nā mea hoʻoheheʻe corrosive nui, e hōʻoia ana i ka lōʻihi a me ka hoʻonui ʻana i ka hana. Hoʻonui kēia kūpaʻa corrosion i ka laulā o nā noi o kēia mau crucibles, ʻoi aku hoʻi i nā ʻoihana kemika a me ka metallurgical.

Hoʻohui ʻia, ʻoi aku ka maikaʻi o kona pale ʻana i ka wela wela ma mua o nā huahana like. Hōʻike ka graphite crucibles i ka elasticity ma lalo o ka hoʻoilo wikiwiki ʻana a me ka hoʻomehana ʻana, e hoʻemi ana iā lākou i ka maʻa a me ka haki. ʻAʻole hoʻomaikaʻi wale kēia paʻa maikaʻi i ka palekana akā hāʻawi pū kekahi i nā kumukūʻai koʻikoʻi ma o ka hōʻemi ʻana i ka pono o nā pani pinepine.

Hoʻohana nui ʻia nā crucibles graphite i nā ʻoihana like ʻole ma muli o kā lākou conductivity thermal maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe. ʻO kēia mau crucibles he haʻahaʻa haʻahaʻa o ka hoʻonui ʻana i ka wela a kū i ka hoʻololi koke ʻana i ka mahana. Hiki iā lākou ke pale i ka hoʻomehana wikiwiki a me ka hoʻomaha ʻole me ka ʻole o ka ʻeha nui, e hōʻoia i ka hana maikaʻi loa a me ka hilinaʻi.

Loaʻa i nā crucibles graphite ke kūʻē i ka corrosion hoʻohālike i ka waika a me ka alkaline solutions, i mea nui i loko o nā laboratories a me nā mea kanu kemika. ʻO ko lākou kūpaʻa maikaʻi loa i nā hopena kemika e hōʻike ana i ko lākou lōʻihi a hiki ke mālama pono i kahi ākea o nā kemika.

ʻO ka hui ʻana o ka graphite crucible he graphite flake maoli ke kumu kumu. Hoʻopaʻa ʻia me ka hoʻohana ʻana i kahi mea hoʻopili kūikawā i kapa ʻia ʻo ka lanahu ahi plastik. ʻO kēia hui like ʻole e hōʻoia i ka mālama ʻana o nā crucibles graphite i ka kūpaʻa o ke kūkulu ʻana ma lalo o nā kūlana paʻakikī, e hāʻawi ana i nā hopena kūlike i nā ʻano noi.

ʻO ka hiki ʻana mai o nā crucibles graphite i hana ʻia ma ka home ʻaʻole ia e hōʻailona i kahi holomua ʻenehana, akā kākoʻo pū kekahi i ka hoʻomohala ʻana i nā ʻoihana kūloko. ʻO nā crucibles kiʻekiʻe i hana ʻia ma ka ʻāina e hōʻemi i ka hilinaʻi ʻana i nā mea lawe mai me ka hāʻawi ʻana i nā kumukūʻai hoʻokūkū no nā ʻano ʻoihana. Hoʻokumu kēia hoʻomohala i ke ala no ka hoʻokō pono ʻana a hoʻoikaika i ka ʻāina ʻoihana ʻāina.

ʻO ka hōʻuluʻulu manaʻo, ua hoʻoneʻe nā mea hou i ka hana graphite crucible i nā kiʻekiʻe hou, ʻoi aku ka nui o nā huahana i lawe ʻia mai e like me ka hana a me ka lōʻihi. ʻOi aku ka maikaʻi o ka thermal conductivity, ʻoi aku ka maikaʻi o ka wela wela, ka corrosion a me ka thermal shock resistance i mea waiwai nui i nā ʻano hana ʻenehana. Me kēia mau holomua, ua hāʻawi nui ka ʻoihana graphite crucible i ka ulu ʻana o ka ʻoihana a me ka hilinaʻi iā ia iho.
