1. Ụlọ ọrụ metallurgical
N'ime ụlọ ọrụ ọla, enwere ike iji ntụ ntụ graphite eke mepụta ihe ndị na-emegharị anya dị ka brik magnesia-carbon na brik carbon-carbon n'ihi ezigbo nguzogide oxidation ya. Enwere ike iji ntụ ntụ graphite artificial mee ihe dị ka electrode na-emepụta ígwè, ma electrodes nke sitere na graphite ntụ ntụ na-esiri ike iji na ọkụ eletrik na-eme ígwè na ọnọdụ ọrụ siri ike.
2. Ụlọ ọrụ igwe
N'ime ụlọ ọrụ igwe, a na-ejikarị ihe graphite eme ihe dị ka ihe na-eguzogide iyi na mmanụ mmanu. Ngwa ngwa mbụ maka nkwadebe nke graphite gbasaa bụ nnukwu carbon flake graphite, yana reagents ndị ọzọ kemịkalụ dị ka sulfuric acid gbanyere mkpọrọgwụ (n'elu 98%), hydrogen peroxide (karịa 28%), potassium permanganate, wdg bụ ndị nrụpụta ọkwa ọkwa niile. N'ozuzu usoro nke nkwadebe dị ka ndị a: na okpomọkụ kwesịrị ekwesị, dị iche iche n'ike-n'ike nke hydrogen peroxide ngwọta, eke flake graphite na concentrated sulfuric acid na-agbakwunyere na usoro dị iche iche, meghachi omume maka oge ụfọdụ n'okpuru mkpali mgbe nile, mgbe ahụ, na-asa na mmiri ruo na-anọpụ iche, na centrifuged. Mgbe mmiri gwụchara, a na-ekpocha ya na 60 Celsius C. Eke graphite ntụ ntụ nwere ezigbo mmanu ma na-ejikarị eme ihe dị ka ihe mgbakwunye maka mmanụ mmanu. Ngwa maka ibufe ihe na-emebi emebi na-eji mgbanaka piston, mgbanaka akara na bearings mere nke ntụ ntụ graphite, na ọ dịghị mkpa ịgbakwunye mmanụ na-ete mmanụ n'oge arụ ọrụ. A pụkwara iji ntụ ntụ graphite eke na polymer resin composite ihe mee ihe n'ọhịa ndị dị n'elu, mana nguzogide eyi adịghị mma dị ka nke ntụ ntụ graphite artificial.
3. Chemical ụlọ ọrụ
Artificial graphite ntụ ntụ nwere njirimara nke nguzogide corrosion, ezigbo okpomọkụ conductivity na ala permeability. A na-ejikarị ya eme ihe na ụlọ ọrụ kemịkalụ na-eme ka ndị na-ekpo ọkụ ọkụ, tankị mmeghachi omume, ụlọ elu absorption, nzacha na ngwá ọrụ ndị ọzọ. A pụkwara iji ntụ ntụ graphite eke na ihe ndị mejupụtara polymer resin mee ihe n'ubi ndị a dị n'elu, mana ikuku okpomọkụ na nguzogide corrosion adịghị mma dị ka nke ntụ ntụ graphite artificial.
Site na mmepe teknụzụ nyocha na-aga n'ihu, atụmanya ngwa nke ntụ ntụ graphite artificial enweghị atụ. Ka ọ dị ugbu a, mmepe nke ngwaahịa graphite wuru na graphite eke dị ka akụrụngwa bụ otu n'ime ụzọ dị mkpa iji gbasaa mpaghara ngwa nke graphite eke. A na-eji ntụ ntụ ntụ ntụ dị ka ihe inyeaka na-emepụta ụfọdụ ntụ ntụ ntụ ntụ, ma mmepe nke ngwaahịa graphite artificial na ntụ ntụ graphite dị ka isi ihe adịghị ezu. Ọ bụ ụzọ kachasị mma iji nweta ihe mgbaru ọsọ a site n'ịghọta na iji usoro na njirimara nke ntụ ntụ graphite, na ịnakwere usoro kwesịrị ekwesị, ụzọ na ụzọ iji mepụta ngwaahịa graphite artificial nwere nhazi pụrụ iche, ihe onwunwe na ojiji.
