Ọla kọpa graphite

Nkọwa dị mkpirikpi:

Ọla kọpa graphite bụ ihe ngwakọta nwere ọla kọpa ntụ ntụ na graphite, nke a na-ejikarị dị ka ihe maka imepụta akụkụ ndị na-eduzi na thermal conductive. Ihe na-esonụ bụ nkọwa ngwaahịa nke graphite ọla kọpa, gụnyere njirimara ya, ojiji, usoro mmepụta ihe, ihe ndị chọrọ mma, wdg.


Nkọwa ngwaahịa

Mkpado ngwaahịa

Njirimara

1. Ezi conductivity: ọla kọpa graphite nwere ezigbo conductivity, na resistivity bụ ihe dịka 30% nke ọla kọpa dị ọcha, nke a pụrụ iji mee ihe dị ka ihe na-eduzi.

2. Ezi conductivity thermal: graphite ọla kọpa nwere ezigbo ikuku thermal conductivity, na okpomọkụ ya dị ihe dị ka ugboro 3 nke ọla kọpa, nke enwere ike iji dị ka ihe na-eme ka ọkụ.

3. Yiri nkwụsi ike na nguzogide corrosion: graphite ọla kọpa nwere nkwụsi ike na-eyi nke ọma na nguzogide corrosion, a pụkwara iji ya rụọ ọrụ n'ibu na nnukwu okpomọkụ, nrụgide dị elu na ọsọ ọsọ.

4. Ezi machinability: ọla kọpa graphite nwere ike na-edozi ngwa ngwa ma gbakọta, a pụkwara iji ya mepụta akụkụ nke ụdị dị iche iche.

Ebumnuche

Ihe ndị bụ isi eji graphite ọla kọpa gụnyere:

1. Na-emepụta akụkụ ndị na-eduzi dị ka electrodes, brushes, njikọ eletrik, wdg

2. Mepụta akụkụ ndị na-eduzi okpomọkụ dị ka ngwaọrụ okpomọkụ na radiator

3. Mepụta akara nke igwe, bearings na akụkụ ndị ọzọ na-eguzogide

4. Ịmepụta ngwaahịa teknụzụ dị elu dị ka ihe elektrọn, ngwaọrụ semiconductor, sel anyanwụ

Usoro mmepụta ihe

Usoro mmepụta nke graphite ọla kọpa dị mfe, n'ozuzu gụnyere usoro ndị a:

1. Ihe eji akwadebe: ntụ ntụ ọla kọpa na ntụ ntụ graphite ga-agwakọta n'otu akụkụ, a ga-etinyekwa mmanụ mmanu na ihe nkedo.

2. Nkwadebe nke ịkpụzi ahụ: pịa ihe agwakọta n'ime ahụ na-akpụzi kwesịrị ekwesị maka nhazi.

3. ihicha na nhazi: kpochaa ịkpụzi ahụ, wee mee usoro, dị ka ntụgharị, igwe igwe, ịkụ ala, wdg.

4. Sintering: na-eme ka akụkụ ndị a na-emepụta ihe na-emepụta ihe siri ike nke graphite ọla kọpa.

Ọdịmma chọrọ

Ọdịmma chọrọ nke graphite ọla kọpa gụnyere akụkụ ndị a:

1. Igwe ọkụ eletrik na ọkụ ọkụ ga-ezute ụkpụrụ achọrọ.

2. Ọdịdị ọdịdị ahụ ga-adị mma na-enweghị mgbawa doro anya, ntinye na afụ.

3. Izi ezi akụkụ ga-ezute ihe ndị a chọrọ nke eserese imewe.

4. Ihe mgbochi na-eyi na nkwụsị nke corrosion ga-ezute ihe eji eme ihe.
