Mmetụta na uru ihe onwunwe nke ngwaahịa graphite

N'ihi ọtụtụ ihe ndị pụtara ìhè, graphite na-achọta ngwa dị ukwuu na igwe, igwe, eletriki, kemịkalụ, textile na ngalaba mmepụta ihe ndị ọzọ. Ọ na-eje ozi dị ka ihe mgbagha ma na-ejigide njirimara kemịkalụ mbụ nke flake graphite ka ọ na-egosipụta njirimara mmanye onwe ya siri ike. Graphite ntụ ntụ e ji akwa ike acid nguzogide, corrosion eguzogide, elu okpomọkụ ndidi ruo 3000 ℃ na ala okpomọkụ resilience ala ruo -204 ℃. Ọzọkwa, ọ na-anya isi a compressive ike karịrị 800kg / Cm2 na-egosi oxidation iguzogide na naanị 1% arọ ọnwụ mgbe ekpughere ikuku na 450 ℃. Ọzọkwa, ọ na-egosiputa ọnụego nlọghachi nke 15-50% (njupụta 1.1-1.5). N'ihi ya, a na-eji ngwaahịa graphite eme ihe na metallurgy, ụlọ ọrụ kemịkalụ, ụlọ ọrụ petrochemical, physics ike dị elu, ikuku ikuku, elektrọn na mpaghara ndị ọzọ.

Ngwaahịa graphite n'onwe ha nwere nnukwu uru:

1, graphite ngwaahịa nwere ezigbo adsorption.

Ọdịdị na-adịghị mma nke carbon na-eme ka carbon nwee ezigbo mgbasa ozi, ya mere a na-ejikarị carbon eme ihe dị ka ihe mgbasa ozi maka ịmị mmiri, ísì, ihe ndị na-egbu egbu na ihe ndị ọzọ. Anyị emewo nnwale, ụbọchị ole na ole gara aga, barbecue ji graphite baking tray dị nnọọ ọcha, ma tinye na induction oven kpo oku, ị ga-ahụ ikpeazụ barbecue adsorption nke griiz na-emerụ bekee ga-eji nwayọọ nwayọọ na-apụta, ma echegbula, na a Enwere ike iji akwụkwọ nri dị ọcha iji hichaa.

2, graphite ngwaahịa nwere ezigbo thermal conductivity, ngwa ngwa nnyefe ọkụ, edo okpomọkụ, mmanụ ụgbọala na-azọpụta.

A na-ekpo ọkụ ngwa ngwa na mpempe akwụkwọ na pans nke graphite, na nri ndị a na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ, na-esi n'ime ya sie ya, na oge ikpo ọkụ dị mkpụmkpụ, ọ bụghị nanị na uto dị ọcha, kamakwa ihe oriri mbụ nke nri nwere ike kpochie. . Anyị emeela nnwale, mgbe a na-eji pan grill graphite eme nri, onye na-esi nri induction kụrụ ọkụ na mmalite, enwere ike kpoo ya naanị 20-30 sekọnd, ma mgbe nri malitere, enwere ike igwu ya na a. obere ọkụ, nke nwere ike ịzọpụta ike.

3, graphite ngwaahịa nwere chemical kwụsie ike na corrosion iguzogide.

Graphite nwere ezigbo nkwụsi ike kemịkalụ n'ime ụlọ ma ọ bụghị acid siri ike, ntọala siri ike na ihe mgbaze organic anaghị ebuso ya agha. Ya mere, ọbụna ma ọ bụrụ na ogologo oge ojiji nke graphite ngwaahịa bụ nnọọ obere ọnwụ, ọ bụrụhaala na ọ na-ehichapụ dị ka ọhụrụ.

Ngwaahịa graphite 4 nwere mmetụta mgbochi-oxidation siri ike na mbelata.

Ngwaahịa, karịsịa graphite na-ekpo ọkụ na-ekpo ọkụ nwere ike ịmepụta ion oxygen na-adịghị mma, na-eme ka ihe ndị gbara ya gburugburu na-arụ ọrụ, na-eme ka ahụike mmadụ dịkwuo mma, na-egbochi ịka nká nke ọma, na-eme ka akpụkpọ ahụ jupụta na-egbuke egbuke na ngbanwe.

5, ngwaahịa graphite ahụike gburugburu ebe obibi, enweghị mmetọ redioaktivu, oke okpomọkụ na-eguzogide.

Carbon nwere ike ịghọ graphite ma ọ dịkarịa ala ụbọchị iri na abụọ na abalị nke graphitization na ọnọdụ okpomọkụ dị elu nke 2000-3300 degrees, ya mere a tọhapụrụ ihe ndị na-egbu egbu na ndị na-emerụ ahụ na graphite ogologo oge ma kwụsie ike n'ime opekata mpe 2000 degrees.

N'otu oge ahụ, ngwaahịa graphite n'ihi nhazi ya pụrụ iche, nke nwere oke nguzogide okpomọkụ, nguzogide okpomọkụ, ọkụ eletrik, mmanu mmanu, nkwụsi ike kemịkalụ na plasticity na ọtụtụ njirimara ndị ọzọ, abụrụla ihe dị mkpa dị mkpa na mmepe nke ndị agha na ụlọ ọrụ ọgbara ọhụrụ. na elu, teknụzụ ọhụrụ na nkọ, ngwaahịa graphite, dị ka mgbanaka graphite, ụgbọ mmiri graphite na-ejikarị eme ihe. Ndị ọkachamara mba ụwa ebuola amụma na "narị afọ nke 20 bụ narị afọ nke silicon, narị afọ nke 21 ga-abụ narị afọ nke carbon."

Dị ka ihe dị mkpa atụmatụ na-abụghị ọla ịnweta ngwaahịa, graphite ụlọ ọrụ ga-emejuputa atumatu oru njikwa. Na mmejuputa atumatu nke ohere usoro, graphite, graphite ngwaahịa, ga-aghọ ọzọ mgbe obere ụwa, fluorine chemical, phosphorus chemical, na-eduga ụlọ ọrụ na ubi a ga-abanye ọhụrụ ogbo nke mmepe.
