Le ndatshana idlulela emhlabeni ngobuningiamabhlogo we-graphite, ehlola izakhiwo zabo, izinhlelo zokusebenza, nokuthi kungani zibalulekile ezimbonini ezinjengezimbiwa zensimbi kanye nabatholakele. Uma ubamba iqhaza ezinqubweni zokushisa okuphezulu, ufuna izinto ezihlukileUkuvuselelwa okushisayo, noma adinge okuthembekileumthumeliOkwakhoi-graphiteIzidingo, lo mhlahlandlela ophelele kufanele ufunde. Inikeza imininingwane ngombono wefekthri, inikezela ngemininingwane ebalulekile yezikhulu zokuthengwa kwempahla kanye nabanikazi benkampani ngokufanayo.
Yiliphi ibhlokhi le-graphite ephezulu?
Amabhulokhi we-graphite aphezulu aphezuluziyizindlela ezikhethekile zei-graphiteKwenziwe ukufeza isakhiwo esihlangene nge-porility encane. Ngokungafani njaloi-graphite, Lawa mabhulokhi anenjiniyela ukunikela ngezakhiwo eziphakeme zemishini kanye nokusebenza ezicelo ezifunwayo.
Lokhu kutholakala ngezinqubo ezithile zokukhiqiza, ezingabandakanya:
- Ukudlidliza, kuthuke futhi ukugazinga:Lokhu kuphindwa kaninginingi.Amabhlogo we-graphitezivinjelwe ukuqinisekisa ubukhulu bomfaniswano,ifakwengama-resins noma iphimbo ukugcwalisa noma yimaphi ama-pores asele, bese-silileemazingeni okushisa aphezulu aze akhanyise impahla ye-filler. Le nqubo yezinyathelo eziningi iphumela kumkhiqizo wokugcina we-denser, onamandla.
- Kusetshenziswa izinto ezisezingeni eliphakeme ezifundwayo:Ikhwalithi ye-coke ne-pitch esetshenzisiwe ibaluleke kakhulu. Izinto zokuhlanza okuphezulu ezinezinto ezithile zokusanhlamvu ezithile zinomthelela kokugcinaUbuningi obuphezuluna-ubumsulwa be-graphite.
- Ukucindezela okuzayo:Ingcindezi ephezulu idalaUbuningi obuphezulu.
Kungani amabhlokhi aphezulu we-graphity graphity ebalulekile kumamitha ensimbi kanye namathole?
Amalunga wensimbi nabatholakele basebenza ngaphansi kwezimo ezimbi kakhulu, ezibandakanyaamazinga okushisa aphezulu, izindawo ezilimazayo, kanye nesidingo senqubo eqondile yokulawula.Amabhulokhi we-graphite aphezulu aphezuluziyizakhi ezibucayi kulezi zimboni ngenxa yenhlanganisela eyingqayizivele yezakhiwo:
- Ukumelana nokushisa okuphezulu: I-graphiteinamaphuzu elinye lamaphoyinti aphezulu okuncibilika (azungeze3850 degreesCelsius) kanyeAmaphoyili abilayo(ezungezeAma-degree angama-4200Celsius) kwanoma yiziphi izinto ezaziwayo. Lokhu kwenzaAmabhulokhi we-graphite aphezulu aphezuluIlungele izinhlelo zokusebenza ezinjeimbuthumaimithofu,amabala, futhiisikhuntaisetshenziswe ngokuncibilika kwensimbi nokuphonsa. Izinto ezibonakalayo zingamelana nalezi zinto zokushisa eziphezulu ngaphandle kokuwohloka okukhulu, ukugcina ubuqotho bayo obuhle.
- Ukusebenza okuhle kakhulu okushisayo: Ukusebenza okuhle okushisayoiqinisekisa ngisho nokusatshalaliswa kokushisa, ukuvikela izindawo ezishisayo nokucindezela okushisayo kui-graphiteizakhi. Lokhu kubalulekile ngezinqubo ezisebenzayo zokuncibilika nokuvimbela ukulimala kwemishini.Amabhulokhi we-graphite aphezulu aphezuluzivame ukusetshenziswa njengeizinto zokushisaphakathi kwa-hambisangenxa yekhono labo lokushisa ngokushesha nangokulingana.
- Ukunwetshwa okuphansi okushisayo:Iqinisekisa amabhlogo awahlali ngesikhathi sokushisa okushisa kakhulu.
Ukuqonda inqubo yokukhiqiza yamabhulokhi we-graphite.
Amabhlogo we-graphitezidalwe ngenqubo elawulwa ngokucophelela eqala ngokukhetha izinto eziphakeme ezisezingeni eliphakeme, njenge-petroleum coke noma i-pitch coke. Inqubo eyisisekelo ichazwe ngezansi:
- Ukuxuba:I-coke inomhlaba ngokucophelela futhi ixubene ne-binder, ngokujwayelekile iphimbo lamalahle. Izilinganiso zilawulwa ngokucophelela ukuze kuqinisekiswe izakhiwo ezifiselekayo kumkhiqizo wokugcina.
- Ukubumba:Ingxube icindezelwe esimweni esifunekayo, imvamisa isebenzisa ukucindezela okuzayo, okusebenza ingcindezi ngokufana kusuka kuzo zonke izinkomba. Lokhu kusiza ukudala ahomogeneousnesakhiwo esiminyene.
- Ukubhaka:Ibhlokhi "eluhlaza" libhakwe kuimbuthumaEmazingeni okushisa azungeze ama-1000 ° C kuya ku-carbonise
- Ukufakwa kabusha:Ukuthuthukisa ukuthuthumela futhi kunciphise i-poorsuty, ibhlokhi ebhakwe kaningiifakwenge-pitch noma i-resin ngaphansi kwe-vacuum nengcindezi.
- Ukuhlunga:Isinyathelo sokugcina, esibalulekile ukuvezwa. Le khasiifakweI-block ifudunyezwa kakhuluamazinga okushisa aphezulu(cishe ngo-3000 ° C) esimweni se-inert. Le nqubo iguqula i-carbon ye-amorphous ibe yi-crystallinei-graphite, Ukudlulisela Izici Zombhalo Wezinto Ezibonakalayo, eziphakemeUkuvuselelwa okushisayokanye nokusebenza kukagesi.
- Imishini:Uma ukunemba kudingeka, ngemuva kokupholisai-graphiteingafakwa imishini ukuze icaciswe ngokwezifiso.
Yiziphi izinhlelo ezibalulekile zamabhulokhi we-graphite aphezulu aphezulu?
Izakhiwo ezihlukile zeAmabhulokhi we-graphite aphezulu aphezuluBenze balungele izinhlobo eziningi zezicelo, ikakhulukazi ezimbonini ezibhekene namazinga okushisa aphezulu nezindawo ezifuna izimo. Nazi ezinye izicelo ezibalulekile:
- Amabhulukwe kanye nokubumba: Ama-graphite ama-brucIbleszisetshenziselwa kabanziukuncibilikaIzinsimbi ezingezona ze-Ferrous njengegolide, isiliva ne-aluminium.Isikhunta se-graphitezisetshenziselwa izinqubo zokuphonsa okuqhubekayo kanye nokukhiqiza izingxenye zensimbi ezahlukahlukene.
- I-EDM (ukukhishwa kukagesi kwemishini): I-graphite ephezulu yokuhlanzaisetshenziswa njengeI-electrodesE-EDM, inqubo esetshenziselwa ukwakheka izinsimbi ezinzima ngokunemba okuphezulu.
- Izikhombo zomlilo: Amabhulokhi we-graphite aphezulu aphezuluzisetshenziselwa ukuhambisa umugqahambisangensimbi futhiinqwabaizimboni, ukuhlinzeka okuhle kakhuluUkumelana nokushisa okuphezulunokuvikelwa kumakhemikhaliukugqwala.
- Amathuluzi we-Sonsoring:Isetshenziswa ezindaweni zokushisa okuphezulu.
Uwukhetha kanjani umphakeli we-graphite we-graphite efanele?
Ukukhetha kwesokudlaumthumeliingomaneAmabhulokhi we-graphite aphezulu aphezulukubalulekile ukuze kuqinisekiswe ikhwalithi nokusebenza kwemisebenzi yakho. Nazi ezinye zezinto ezibalulekile okufanele zicatshangelwe, ngokubuka okuvela ku-Allen's (China-based Factory) Umbono:
- Isipiliyoni nobuchwepheshe:Funa aumenzingerekhodi elifakazelwe ekukhiqizeniIgrafu ephezulu-density. Umphakeli onemigqa eminingi yokukhiqiza (njengefektri ye-Allen nge-7) imvamisa ibonisa amandla aphezulu nesipiliyoni.
- Ikhwalithi yokulawula:Cela imininingwane mayelanaUmhlinzekiizinqubo zokulawula ezisezingeni eliphakeme. Izitifiketi ezinjenge-ISO 9001 ziyizinkomba ezinhle zokuzibophezela kwekhwalithi. Buza ngezinqubo zokuhlola izinto ezibonakalayo nokuthi ngabe zinikeza imininingwane eningiliziwe ebonakalayo.
- Amandla okwenza ngokwezifiso:Izicelo eziningi zidingaamabhlogo we-graphitengobukhulu obuthile, ukwakheka, noma izakhiwo. Okuhleumthumelikufanele ikwazi ukunikela ngezinketho zokwenza ngokwezifiso ukufeza izidingo zakho ngqo.
- Ukuxhumana, njengo-Allen noMark babe:Ukuxhumana kungukukhathazeka okubalulekile kubathengi abaningi.
Uyini umehluko phakathi kwegrafu ebunjiwe ne-isostatic graphite?
Ngenkathi bobabili bayizindlela zei-graphitial graphite, kunomehluko obalulekile phakathiI-graphite ebunjiwefuthi i-isostatici-graphite:
- Igrafu ebunjiwe:Lolu hlobo lwei-graphitekukhiqizwa ngokucindezela ingxube yekhabhoni endaweni eyodwa. Lokhu kuphumela empahleni ye-anotropic, okusho ukuthi izakhiwo zihlukile ngokuya ngokuqondisa.I-graphite ebunjiweimvamisa ibiza kakhulu kepha inamandla aphansi nokuqina okuqhathaniswa ne-isostatici-graphite.
- I-ISostatic Graphite:Lokhu kukhiqizwa ngokusebenzisa ingcindezi ngokufana kusuka kuzo zonke izinkomba (ukucindezela okuzayo). Lokhu kuphumela kuhomogeneouskanye ne-isotropic impahla, okusho ukuthi izakhiwo ziyefana kuzo zonke izinkomba. Isostatici-graphiteinikeza ubukhulu obuphakeme, amandla, futhiUkuvuselelwa okushisayouma kuqhathaniswaI-graphite ebunjiwe.
Yiziphi izinto ezibalulekile ezibonakalayo zamabhlokhi we-graphite aphezulu aphezulu?
Amabhulokhi we-graphite aphezulu aphezuluInenhlanganisela eyingqayizivele yezakhiwo ezizenza zilungele izinhlelo zokusebenza ezifunwayo:
