Incazelo yomkhiqizo: i-graphite
I-graphite powder ithambile, imnyama grey, inamafutha futhi ingangcolisa iphepha. Ubulukhuni bungu-1-2, futhi bukhuphuka bufinyelele ku-3-5 ngokwanda kokungcola eceleni kokuqondisa okuqondile. Amandla adonsela phansi athile angu-1.9-2.3. Ngaphansi kwesimo sokuhlukaniswa komoya-mpilo, indawo yayo yokuncibilika ingaphezu kuka-3000 ℃, okungenye yamaminerali amelana kakhulu nezinga lokushisa. Emazingeni okushisa asekamelweni, izakhiwo zamakhemikhali ze-graphite powder azinzile, azincibiliki emanzini, i-asidi ehlanjululwe, i-alkali ehlanjululwe kanye nezinyibilikitsi eziphilayo; impahla inokumelana nokushisa okuphezulu kanye ne-conductivity, futhi ingasetshenziswa njenge-refractory, i-conductive material, i-wear-resistant and lubricating material.
Ngenxa yesakhiwo sayo esikhethekile, i-graphite inezici ezilandelayo: 1. Ukumelana nokushisa okuphezulu: indawo yokuncibilika ye-graphite ingu-3850 ± 50 ℃, futhi indawo yokubilisa ingu-4250 ℃. Okusho ukuthi, izinga lokulahlekelwa kwesisindo kanye ne-coefficient yokwanda okushisayo kuncane kakhulu uma usebenzisa i-arc sintering yokushisa ephezulu kakhulu, futhi amandla e-graphite akhula ngokunyuka kwezinga lokushisa. Ngo-2000 ℃, amandla egraphite aphindwe kabili. 2. Ukuthambisa: ukuthambisa kwegraphite kuncike kusayizi wegraphite. Uma isikali sisikhulu, i-coefficient ye-friction iba yincane, futhi kuba ngcono ukusebenza kokugcoba. 3. Ukuzinza kwamakhemikhali: i-graphite inokusimama okuhle kwamakhemikhali ekamelweni lokushisa, imelana ne-asidi, i-alkali kanye ne-organic solvent corrosion. 4. Ipulasitiki: i-graphite inokuqina okuhle futhi ingacindezelwa ibe amashidi amancane. 5. Ukumelana nokushaqeka okushisayo: lapho i-graphite isetshenziswa ekamelweni lokushisa, ingakwazi ukumelana noshintsho olukhulu lokushisa ngaphandle kokulimala. Lapho izinga lokushisa likhuphuka ngokuzumayo, umthamo we-graphite ngeke ushintshe kakhulu futhi ngeke kube nemifantu.
Isebenzisa:
1. Njengezinto eziphikisayo: i-graphite nemikhiqizo yayo inezici zokumelana nokushisa okuphezulu namandla aphezulu. Ngokuyinhloko zisetshenziselwa ukukhiqizai-graphite crucibleembonini ye-metallurgical, futhi ngokuvamile isetshenziswa njenge-ejenti yokuvikela ingot yensimbi kanye nolwelwesi lwesithando somlilo.
2. Njengempahla yokugcoba engagugi: i-graphite ivame ukusetshenziswa njengamafutha embonini yemishini. Amafutha okugcoba ngokuvamile awafaneleki isivinini esikhulu, izinga lokushisa eliphezulu nokucindezela okukhulu.
3. I-graphite inokusimama okuhle kwamakhemikhali. Isetshenziswa kabanzi embonini ye-petrochemical, i-hydrometallurgy, ukukhiqizwa kwe-asidi-base, i-synthetic fiber, ukwenza iphepha neminye imikhakha yezimboni, engasindisa izinto eziningi zensimbi.
4. I-graphite ingasetshenziswa njengomthofu wepensela, i-pigment kanye ne-ejenti yokupholisha. Ngemuva kokucubungula okukhethekile, i-graphite ingenziwa ibe yizinto ezihlukahlukene ezikhethekile ezizosetshenziswa iminyango yezimboni efanele.
