Ụlọ ọrụ mpịakọta
Graphite nwere ezigbo nkwụsi ike kemịkalụ.graphite edoziri nke ọma nwere njirimara nke nguzogide corrosion, ezigbo thermal conductivity na obere permeability.A na-ejikarị ya eme ihe ndị na-ekpo ọkụ ọkụ, tankị mmeghachi omume, condensers, ụlọ ọkụ ọkụ, ụlọ elu absorption, coolers, heaters, nzacha na mgbapụta akụrụngwa.A na-eji ya eme ihe na petrochemical, hydrometallurgy, acid na alkali mmepụta, eriri sịntetik, akwụkwọ na ụlọ ọrụ mmepụta ihe ndị ọzọ, nke nwere ike ịchekwa ọtụtụ ihe ígwè.

Ejiri ya dị ka ihe nkedo, ebe a na-emepụta ihe, ịkpụzi na ihe ndị na-ekpo ọkụ na-ekpo ọkụ: N'ihi obere mgbasawanye ọkụ nke graphite na ikike ya iguzogide mgbanwe nke ngwa ngwa ngwa ngwa na okpomọkụ, enwere ike iji ya dị ka ihe eji eme ihe maka glassware.Mgbe ejiri graphite mee ihe, metal ferrous nwere ike nweta nha nkedo ziri ezi, oke elu elu, enwere ike iji ya na-enweghị nhazi ma ọ bụ obere nhazi, si otú a na-azọpụta ọtụtụ ígwè.Maka mmepụta nke carbide cimented na usoro ntụ ntụ ndị ọzọ, a na-ejikarị ihe graphite eme ụgbọ mmiri seramiiki maka ịpị na ịgbanye.Igwe ihe na-eto kristal nke silicon monocrystalline, akpa nnụcha mpaghara, mwekota nkwado, ọkụ induction, wdg bụ ihe graphite dị oke ọcha.Na mgbakwunye, graphite nwekwara ike iji dị ka graphite mkpuchi efere na isi maka agụụ smelting, elu okpomọkụ na-eguzogide ọkụ tube, mkpanaka, efere, lattice na ndị ọzọ components.

Graphite nwekwara ike igbochi ikpo ọkụ ọkụ.Nnwale otu dị mkpa na-egosi na ịtinye ụfọdụ ntụ ntụ graphite (ihe dịka gram 4 ~ 5 kwa ton mmiri) na mmiri nwere ike igbochi ikpo ọkụ n'elu.Tụkwasị na nke ahụ, mkpuchi graphite na chimni ígwè, ụlọ elu, àkwà mmiri na pipeline nwere ike igbochi corrosion na nchara.

Enwere ike iji graphite mee ihe dị ka ụzọ pensụl, pigmenti na ihe na-egbuke egbuke.Mgbe nhazi pụrụ iche, graphite nwere ike ime ka ọ bụrụ ihe dị iche iche pụrụ iche maka ngalaba mmepụta ihe dị mkpa.

Na mgbakwunye, graphite bụkwa ihe na-egbu egbu na onye na-ahụ maka iko na akwụkwọ na ụlọ ọrụ ọkụ, yana akụrụngwa dị mkpa maka imepụta pensụl, ink, agba ojii, ink, diamond artificial na diamond.Ọ bụ ezigbo nchekwa ike yana ihe nchekwa gburugburu ebe obibi, nke ejirila dị ka batrị ụgbọ ala na United States.Site na mmepe nke sayensị ọgbara ọhụrụ, teknụzụ na ụlọ ọrụ, mpaghara ngwa nke graphite ka na-agbasawanye.Ọ ghọwo ihe dị mkpa maka ihe ndị mejupụtara ihe ọhụrụ na mpaghara teknụzụ dị elu ma na-arụ ọrụ dị mkpa na akụ na ụba mba.

Mpịakọta nchekwa mba
A na-eji ya na ụlọ ọrụ ike atọm na ụlọ ọrụ nchekwa mba: graphite nwere ezigbo neutron moderator maka ojiji na reactor uranium-graphite bụ ụdị reactor atomic nke a na-ejikarị eme ihe.Ihe na-emebi emebi na reactor nuklia eji dị ka ike kwesịrị inwe ebe mgbaze dị elu, nkwụsi ike na nguzogide corrosion.Graphite nwere ike imezu ihe a chọrọ n'elu.Ịdị ọcha nke graphite e ji mee ihe dị ka ihe na-emepụta ihe na-emepụta ihe dị elu nke ukwuu, na ọdịnaya adịghị ọcha ekwesịghị ịfe ọtụtụ PPM.Karịsịa, ọdịnaya boron kwesịrị ịbụ ihe na-erughị 0.5PPM.N'ime ụlọ ọrụ nchekwa mba, a na-ejikwa graphite mee oghere nke rọketi mmanụ siri ike, cone nke ngwa agha, akụkụ nke akụrụngwa igodo oghere, ihe mkpuchi ọkụ na ihe mgbochi ọkụ.
