I-graphite powder inezinto eziningi ezinhle kakhulu, ngakho-ke isetshenziswa kabanzi kwezensimbi, imishini, ugesi, amakhemikhali, izindwangu, ukuvikela izwe kanye neminye imikhakha yezimboni. Izinkambu zokusetshenziswa ze-graphite powder yemvelo kanye ne-graphite powder yokwenziwa zinezingxenye ezigqagqene kanye nomehluko. Umhleli olandelayo we-Furuite graphite wethula izinkambu zokusetshenziswa ze-graphite powder kanye ne-graphite powder yokwenziwa.
1. Imboni ye-Metallurgical
Embonini ye-metallurgical, i-graphite powder yemvelo ingasetshenziswa ukukhiqiza izinto eziphikisayo ezifana nezitini ze-magnesia-carbon nezitini ze-aluminium-carbon ngenxa yokumelana kwayo okuhle kwe-oxidation. I-graphite powder yokwenziwa ingasetshenziswa njenge-electrode yokwenza insimbi, kodwa ama-electrode enziwe ngempushana ye-graphite yemvelo kunzima ukuwasebenzisa ezithandweni zikagesi ezenza insimbi ezinezimo zokusebenza ezinzima.
2. Imboni yemishini
Embonini yemishini, izinto ze-graphite zivame ukusetshenziswa njengezinto ezingagugi futhi zokugcoba. Impahla yokuqala eluhlaza yokulungiswa kwegraphite enwebekayo i-high-carbon flake graphite, namanye ama-reagents amakhemikhali afana ne-concentrated sulfuric acid (ngaphezu kuka-98%), i-hydrogen peroxide (ngaphezu kuka-28%), i-potassium permanganate, njll. ama-reagents. Izinyathelo ezijwayelekile zokulungiselela zimi kanje: ekushiseni okufanelekile, izilinganiso ezihlukene zesisombululo se-hydrogen peroxide, i-flake yemvelo ye-graphite kanye ne-concentrated sulfuric acid yengezwe ngezinqubo ezahlukene, isabela isikhathi esithile ngaphansi kokugqugquzelwa njalo, bese igezwa ngamanzi kuze kube yilapho. ingathathi hlangothi, futhi i-centrifuged. Ngemva kokuphelelwa amanzi emzimbeni, yomiswa nge-vacuum ku-60 °C. Impushana ye-graphite yemvelo inokuthambisa okuhle futhi ivame ukusetshenziswa njengesengezo samafutha okugcoba. Imishini yokudlulisa i-corrosive medium isebenzisa kakhulu izindandatho ze-piston, izindandatho zokuvala nama-bearings ezenziwe nge-graphite powder yokwenziwa, futhi ayidingi ukwengeza uwoyela wokugcoba ngesikhathi sokusebenza. I-graphite powder yemvelo kanye nezinto ezihlanganisiwe ze-polymer resin nazo zingasetshenziswa kule mikhakha engenhla, kodwa ukumelana nokugqokwa akukuhle njengalokho kwe-graphite powder yokwenziwa.
3. Imboni yamakhemikhali
I-graphite powder yokwenziwa inezici zokumelana nokugqwala, ukuhanjiswa okuhle kokushisa kanye nokungena okuncane. Isetshenziswa kabanzi embonini yamakhemikhali ukwenza izishintshi zokushisa, amathangi okusabela, imibhoshongo yokumuncwa, izihlungi nezinye izinto zokusebenza. I-graphite powder yemvelo kanye nezinto ezihlanganisiwe ze-polymer resin nazo zingasetshenziswa emikhakheni engenhla, kodwa ukuqhutshwa kokushisa okushisayo nokumelana nokugqwala akukuhle njengalezo ze-graphite powder yokwenziwa.
Ngokuthuthukiswa okuqhubekayo kobuchwepheshe bokucwaninga, ithemba lokufaka isicelo se-graphite powder yokwenziwa alinakulinganiswa. Njengamanje, ukuthuthukiswa kwemikhiqizo ye-graphite yokwenziwa ene-graphite yemvelo njengento eluhlaza kungenye yezindlela ezibalulekile zokwandisa insimu yesicelo se-graphite yemvelo. Impushana ye-graphite yemvelo njengensimbi ewusizo iye yasetshenziswa ekukhiqizeni enye i-graphite powder yokwenziwa, kodwa ukuthuthukiswa kwemikhiqizo ye-graphite yokwenziwa nge-graphite powder yemvelo njengoba impahla eluhlaza eyinhloko ayanele. Kuyindlela engcono kakhulu yokufeza lo mgomo ngokuqonda ngokugcwele nokusebenzisa isakhiwo kanye nezici ze-graphite powder yemvelo, nokwamukela izinqubo ezifanele, imizila nezindlela zokukhiqiza imikhiqizo ye-graphite yokwenziwa enesakhiwo esikhethekile, izakhiwo kanye nokusetshenziswa.
