Kungani ama-prography exlels njengoba womabili ama-lubricant kanye ne-electrode: impahla ebeka izindima ezimbili ezimbili 

Ezihlotsheni zezimboni, izinto ezimbalwa zezinto eziyizimbangi zezinto eziyizimbangi eziguquguqukayo. Kumi ukuphuma ngokugcwalisa imisebenzi emibili ebonakala ephikisana: esebenza njengomthamo owomile futhi isebenza njengo-electrode osebenza kakhulu. Lokhu kusebenza okumbaxambili kuvela esigabeni se-graphictochemical esiyingqayizivele se-graphitoch - inhlanganisela ekhethekile yokwakhiwa kwe-crystalline okuyisisekelo nokusebenza kukagesi okuvelele.

I-Graphite njenge-lubricant: i-molecular glides ngezimo ezimbi kakhulu

I-Graphite yenza kahle ezindaweni lapho izindawo ezijwayelekile zihluleka khona. Lokhu kungenxa yesakhiwo sayo esibekiwe, okubandakanya izingqimba ze-hexagonal ze-hexagonal ze-hexagonal carbon ezibanjwe ndawonye ngamabutho abuthakathaka we-van der Waals. Lezi zingqimba zislayida phezu komunye nomunye kalula, zinikeza isikhombimsebenzisi esiphansi semvelo.

Ngokungafani no-oyela noma amafutha ancike ekuvulekekeni, imisebenzi ye-graphite njengokuthambisa okuqinile kombuso ngesakhiwo sayo sobuntu. Lokhu kwenza kubekele ikakhulukazi:

Izicelo ze-1.aerospace: Igqoko le-graphite linciphisa ukugqoka enjini nasezingxenyeni ze-turbine ngaphansi kwengcindezi ephezulu ye-vacuum ne-thermal.

Ukuhanjiswa kwe-2.automomotive: I-Graphite iqinisekisa ukusebenza okubushelelezi lapho ukujikeleza kwejubane eliphezulu kubangela ukugcotshwa okujwayelekile ukusakazeka.

Izindlela ze-3.Precision: Kusetshenziswe kukhiye nezinsimbi ezinhle lapho uwoyela ungakhanga uthuli, i-graphite inikeza ukuthambisa okuhlanzekile neyomile.

I-Graphite njenge-electrode: Ukuvuselelwa ngokuqina kwesakhiwo

Iqhaza le-graphite njengoba i-electrode isekelwe ngenethiwekhi yayo ye-Π-electron edidekile. I-athomu ngalinye le-carbon endizeni eyi-hexagonal yakha izibopho ezintathu ezivusa ama-combared, i-elektroni yesine ekhululekile ukuhambisa, okuholela ekuqhumeni kukagesi okuphezulu.

Kepha uCharoity wedwa awanele. Emakamerli e-arc kagesi (EAF) nezinhlelo ze-electrolysis, ama-electrodes kumele akhuthazele:

Amazinga okushisa aphezulu aphezulu (aze afike ku-3500 ° C ngesikhathi sokuphuma kwe-ARC)

Izindawo ezinolaka ezinolaka

I-3.MeChanical Erosion kusuka ekuqhumeni nasekuhambeni

I-Graphite ihlangabezana nalezi zidingo zibonga:

Ukuqina kwe-1.Izinyoni: Kuhlala kuzinzile ngokuhlelekile futhi kuyamangaza kunokuba kufezeke emazingeni okushisa aphezulu.

I-2.Chemical Intertness: Iphikisa i-oxidation kanye nokugqwala kuwo wonke ama-electrolyte acidic nakuyisisekelo.

3.Excellent Imishini: Inika amandla ama-design ama-elektrode ayinkimbinkimbi, abalulekile ekukhishweni kukagesi (EDM) nokuphonswa okuqhubekayo.

I-Spectrum yesicelo: Umsebenzi wokuhlangana

Izicelo ezomile zokuthambisa

Izinjini ze-1.jet nezinhlelo ze-aerospace: Izimbobo ezivikelayo zinciphisa ukugqoka ngaphansi kokushisa okushisayo kanye ne-vacuum ngokweqile.

2.Vumuum Metallurgy: Gybsa izingxenye ezinyakazayo ngaphandle kokungcolisa izindawo ezibucayi.

Izinsizakusebenza ze-3.igh-traction: Kuvimbela ukwenza imisebenzi emikhulu emihlanganweni emincane.

Izicelo ze-Electrode

I-1.Aluminum Electrolysis: Ama-electrodes we-graphite aletha okukhona kuma-molten crywolite baths ngaphandle kokuphendula ngamakhemikhali.

Amabhethri we-2.lithium-ion: Izinto ze-anode ezivame ukusetshenziswa i-graphite ukuze zihlanganyele i-lithium ion ngesikhathi semijikelezo yokukhipha.

3..EDM mainingining: Inika amandla ukwakheka okunengqondo okuphezulu kwensimbi nokubumba, ngokuqina okungaguquki kwesilinganiso.

4.Steel ekhiqiza: I-EHP graphite electrodes drive drive arc izimfanelo ezincibilikayo zincibilike kwimikhiqizo emisha ye-alloy.

Isiphetho: I-carbon multitool

Amandla ka-Graphite okwenza ama-roles ahlukene kakhulu avela ekwakhiweni kwawo kwezinga le-athomu. Inhlanganisela yayo yokuthambisa okuhlanganisiwe kanye nokuphakelayo nge-elekthronikhi kwenze kwaba yinto ebaluleke kakhulu ezimbonini ezisukela ku-metallurgy ku-Serder Storage.

Ukusuka ezindlini ze-aerospace kumaseli ebhethri, i-graphite ihlala ingenye yezinto ezinhle kakhulu zezobuchwepheshe nezenhlaka ngokufanele ekwenziweni kwanamuhla.
