Eli nqaku lidla ubomi kwihlabathi lonkeIibhloko zegrafu, ehlola iipropathi zabo, izicelo, kwaye kutheni zibalulekile kwimizi mveliso njengemigca yentsimbi kunye neziseko. Ukuba ubandakanyeka kwiinkqubo zobushushu obuphakamileyo, ukufuna izixhobo ngokwahlukileyoukuqhubela phambili kwe-thermal, okanye ufuna ukuthembekaumboneleliyeyakhoigrafuIimfuno, esi sikhokelo sibanzi kufuneka sifunde. Inika ulwazi oluphuma kumzi mveliso, ukuhambisa ulwazi oluxabisekileyo kumagosa okuthengwa kunye nabanikazi benkampani ngokufanayo.
Yintoni ibhloko yegraphite ephezulu?
Iibhloko zegraphithi eziphezuluziifom ezikhethekileyo zeigrafuyenziwe ukuze kufezekiswe isakhiwo se-compact esine-surusity encinci. Ngokungafaniyoigrafu, ezi bhloko zinenjini yokubonelela ngeepropathi zonxibelelwano eziphezulu kunye nokusebenza kwizicelo ezifunwayo.
Oku kufezekiswa kwiinkqubo ezithile zokwenza izinto, ezinokubandakanya:
- Ukushukuma, ukungena kunye nokugqobhoza:Oku kuphindaphindwa amaxesha amaninzi.Iibhloko zegrafuzidityaniswe ukuqinisekisa ukuxinana okufanayo,ifakwenge-resins okanye i-pitch ukuze ugcwalise nayiphi na ipores, emva kokoirhabaxaKumaqondo obushushu aphezulu akhangelene umxholo wefilitha. Le nkqubo yamanyathelo amaninzi isiphumo se-denser, imveliso yokugqibela eyomeleleyo.
- Sebenzisa izixhobo ezikumgangatho ophezulu:Umgangatho we-coke kunye ne-pitch esetyenziswe yiparamount. Izinto ezicocekileyo ezicocekileyo ezinezakhiwo ezithile zenkozo zinegalelo kwilokugqibelaukuxinana okuphezulukwayeUkucoceka kwegrafu.
- Ukucinezela i-isostatic:Uxinzelelo oluphezulu ludalaukuxinana okuphezulu.
Kutheni le nto iibhloko zegraphite eziphezulu zibalulekile kwiimpuku zentsimbi kunye neziseko?
Ii-Mills zentsimbi kwaye iziseko zisebenza phantsi kweemeko ezigqithisileyo, zibandakanyaamaqondo obushushu aphezuluIindawo zemithombo yobutyebi, kunye nemfuno yolawulo lwenkqubo echanekileyo.Iibhloko zegraphithi eziphezuluzizinto ezibalulekileyo kula mashishini ngenxa yokudityaniswa kweepropathi:
- Ukunganyangeki kobushushu obuphezulu: IgrafuIqhayiya elinye lezinto eziphezulu zokunyibilika (ngeenxa zonkeNgama-3850 degreesCelsius) kwayeAmanqaku abilayo(ngeenxa zonkeI-4200 idigriCelsius) kuyo nayiphi na impahla eyaziwayo. Oku kwenzaIibhloko zegraphithi eziphezuluIlungele izicelo ezinjeisithando somliloILinengs,Iinqaba, kwayeukubumbaisetyenziselwe ukunyibilika kwentsimbi kunye nokuphosa. Izinto ezibonakalayo zinokumelana nobushushu obugqithisileyo ngaphandle kokuthambisa okukhulu, ukugcina ingqibelelo yayo.
- Ukuqhutywa kwengqondo okuhle: Ukuqhubela phambili kwenkunkumaUkuqinisekisa ukuhanjiswa kobushushu, ukuthintela amabala ashushu kunye noxinzelelo lwe-thermal kwiigrafuizinto. Oku kubalulekile kwiinkqubo zokunyibilika ngokufanelekileyo kwaye kuthintele umonakalo kwizixhobo.Iibhloko zegraphithi eziphezuluzihlala zisetyenziswa njengeIzinto zokufudumezangaphakathiizikoNgenxa yokwazi kwabo ukukhawuleza kunye nokudlulisela ubushushu obufanayo.
- Ulwandiso oluphantsi lomhlaba:Iqinisekisa iibhloksi azilwi ngexesha leenkqubo eziphakamileyo zobushushu.
Ukuqonda inkqubo yokwenziwa kweebhloko zegrafu.
Iibhloko zegrafuzidalwe ngenkqubo elawulwa ngononophelo eqala ngokukhetha izixhobo eziphezulu eziphezulu, ezinjengePetroleum Coke okanye i-pitch coke. Inkqubo esisiseko ichaziwe apha ngezantsi:
- Ukuxuba:I-coke yomhlaba kwaye ixutywe ne-binder, i-Coal Tat Tatch. Umlinganiso ulawulwa ngocoselelo ukuqinisekisa ukuba iipropathi eziyimfuneko kwimveliso yokugqibela.
- Ukubumba:Umxube emva koko ucinezelwa kwimo efunwayo, edla ngokusebenzisa ukucinezela isostatic, esebenza ngenkqubo efanayo kuwo onke amacala. Oku kunceda ukwenza ihomogeneouskunye nesakhiwo esimnyama.
- Ukubhaka:Ibhloko "eluhlaza" ibhakiwe kwiisithando somliloKumaqondo obushushu ajikeleze i-1000 ° C ukuba ikharbhisi i-binder.
- Ukungavavanywa:Ukuqhubela phambili ukomeleza ukuxinana kunye nokunciphisa ukuthambeka, ibhloko ebhakiweyo ihlalaifakwenge-pitch okanye i-resin phantsi kwe-vacuum kunye noxinzelelo.
- I-PARAPTION:Inqanaba lokugqibela, elibalulekileyo yigrafiki. IifakweIbhloko ishushu kakhuluamaqondo obushushu aphezulu(malunga ne-3000 ° C) kwindawo ye-InErt. Le nkqubo iguqula i-amorphon carbon kwi-crystallineigrafu, ukudlulisela iipropathi zophawu lwezinto ezibonakalayo, ezinjalo phezuluukuqhubela phambili kwe-thermalukuqhubela phambili kombane.
- Matshini:Ukuba kufanelekile, emva kokupholisaigrafuingaba ngoomatshini kwinkcazo yesiqhelo.
Zithini izinto eziphambili ze-pitelite ye-piteite ephezulu?
Iipropathi ezizodwa zeIibhloko zegraphithi eziphezuluBenze balungele uluhlu olubanzi lwezicelo, ngakumbi kumashishini ajongana nobushushu obuphakamileyo kunye nokufuna indawo. Nazi ezinye iinkqubo eziphambili:

Nguwuphi umahluko phakathi kwegrafu yegraphite kunye ne-isostatic pir?
Ngelixa zombini zizinto zeigrafu yokufakelwa, kukho umahluko ophambili phakathiIgrafu yeGreyitikunye ne-isostaticigrafu:
- Igrafu ye-GARD:Olu hlobo lweigrafuiveliswa ngokucinezela umxube wekhabhoni kwindawo enye. Oku kukhokelela kwiPropathi ye-ANISTROPIC, kuthetha ukuba iipropathi zahlukile kuxhomekeka kwicala.Igrafu yeGreyitiNgokwesiqhelo kuyabiza kakhulu kodwa kunamandla aphantsi kunye noxinano xa kuthelekiswa ne-isostaticigrafu.
- I-Sostatic igraphite:Oku kuveliswa kukusebenzisa uxinzelelo ngokungafaniyo kuzo zonke iindlela (ukucinezela isostatic). Oku kuphumela kwihomogeneouskunye ne-isotropic, kuthetha ukuba iipropathi ziyafana kuzo zonke iindlela. Isostaticigrafuinika uxinzelelo oluphezulu, amandla, kwayeukuqhubela phambili kwe-thermalkuthelekiswa neIgrafu yeGreyiti.
Zeziphi izinto eziphambili zezinto ezibonakalayo zeebhloko zegraphite eziphezulu?
