Incazelo Yomkhiqizo: i-graphite
Impuphu ye-graphite ithambile, imnyama grey, inamafutha futhi ingangcolisa iphepha. Ubulukhuni bungu-1-2, futhi bukhuphuka bube ngu-3-5 ngokwanda kokungcola ohlangothini oluqondile. Amandla adonsela phansi athile angu-1.9-2.3. Ngaphansi kwesimo sokuhlukaniswa komoya-mpilo, iphuzu layo lokuncibilika lingaphezu kuka-3000 ℃, okungenye yamaminerali amelana kakhulu nokushisa. Ezingeni lokushisa legumbi, izakhiwo zamakhemikhali zempuphu ye-graphite zizinzile, azincibiliki emanzini, zincibilikisa i-asidi, zincibilikisa i-alkali kanye nezinyibilikisi eziphilayo; le nto inokumelana nokushisa okuphezulu kanye nokuqhuba, futhi ingasetshenziswa njengezinto eziphikisayo, eziqhuba umoya, ezingagugi futhi ezithambisayo.
Ngenxa yesakhiwo sayo esikhethekile, i-graphite inezici ezilandelayo: 1. Ukumelana nokushisa okuphezulu: iphuzu lokuncibilika kwe-graphite lingu-3850 ± 50 ℃, kanti iphuzu lokubila lingu-4250 ℃. Okusho ukuthi, izinga lokulahlekelwa isisindo kanye ne-coefficient yokwanda kokushisa kuncane kakhulu uma kusetshenziswa i-arc sintering yokushisa ephezulu kakhulu, futhi amandla e-graphite ayanda ngokwanda kokushisa. Ku-2000 ℃, amandla e-graphite aphindwe kabili. 2. Ukuthamba: ukuthamba kwe-graphite kuncike kusayizi we-graphite. Uma isikali sikhulu, i-coefficient yokungqubuzana iba ncane, futhi ukusebenza kokuthamba kuba ngcono. 3. Ukuzinza kwamakhemikhali: i-graphite inokuqina okuhle kwamakhemikhali ekushiseni kwegumbi, imelana nokugqwala kwe-acid, i-alkali kanye ne-organic solvent. 4. I-Plasticity: i-graphite inokuqina okuhle futhi ingacindezelwa ibe amashidi amancane. 5. Ukumelana nokushaqeka kokushisa: lapho i-graphite isetshenziswa ekushiseni kwegumbi, ingamelana noshintsho olukhulu lokushisa ngaphandle kokulimala. Uma izinga lokushisa likhuphuka ngokuzumayo, umthamo we-graphite ngeke ushintshe kakhulu futhi ngeke kube khona imifantu.
Ukusetshenziswa:
1. Njengezinto eziphikisayo: i-graphite nemikhiqizo yayo inezimpawu zokumelana nokushisa okuphezulu kanye namandla aphezulu. Zisetshenziswa kakhulu ekukhiqizeniisitsha sokubethela se-graphiteembonini yensimbi, futhi zivame ukusetshenziswa njenge-ejenti yokuvikela insimbi ye-ingot kanye ne-lining yesithando sensimbi.
2. Njengezinto zokugcoba ezingagugi: i-graphite ivame ukusetshenziswa njengezinto zokugcoba embonini yemishini. Uwoyela wokugcoba ngokuvamile awufanelekeli isivinini esiphezulu, izinga lokushisa eliphezulu kanye nomfutho ophezulu.
3. I-Graphite inamandla amahle okuqina kwamakhemikhali. Isetshenziswa kabanzi embonini ye-petrochemical, i-hydrometallurgy, ukukhiqizwa kwe-acid-base, i-fibre yokwenziwa, ukwenza iphepha kanye neminye imikhakha yezimboni, okungonga izinto eziningi zensimbi.
4. I-Graphite ingasetshenziswa njenge-lead yepensela, i-pigment kanye ne-polishing agent. Ngemva kokucubungula okukhethekile, i-graphite ingenziwa ibe izinto ezikhethekile ezahlukahlukene ezizosetshenziswa yiminyango yezimboni efanele.
