1. Ishishini lesinyithi
Kwishishini le-metallurgical, i-graphite powder yendalo ingasetyenziselwa ukuvelisa izinto eziphikisayo ezifana nezitena zekhabhoni ye-magnesium kunye ne-aluminium carbon brick ngenxa yokumelana kwayo ne-oxidation. Umgubo wegraphite ongeyonyani unokusetyenziswa njenge-electrode ye-steelmaking, kodwa i-electrode eyenziwe nge-graphite powder yendalo inzima ukuba isetyenziswe kwiziko lombane le-steelmaking.
2. Ishishini loomatshini
Kumashishini oomatshini, izinto zegraphite zidla ngokusetyenziswa njengezinto zokunxiba ezixhathisayo kunye nezokuthambisa. Izinto zokuqala ekrwada ukulungiselela igraphite eyandisiweyo iphezulu carbon flake graphite, kunye nezinye reagents imichiza ezifana concentrated sulfuric acid (ngaphezu 98%), peroxide hydrogen (ngaphezu 28%), permanganate potassium kunye nezinye reagents zoshishino zisetyenziswa. Amanyathelo aqhelekileyo okulungiselela alandelayo: kwiqondo lokushisa elifanelekileyo, imilinganiselo eyahlukeneyo yesisombululo se-hydrogen peroxide, i-graphite yendalo ye-flake kunye ne-asidi ye-sulfuric egxininisiweyo yongezwa kwiinkqubo ezahlukeneyo, kwaye iphendule ixesha elithile phantsi kokuphazamiseka rhoqo, emva koko ihlanjwe ukungathathi hlangothi, ukwahlula phakathi kwe-centrifugal. , ukuphelelwa ngamanzi emzimbeni kunye nokoma kwevacuum kuma-60 ℃. I-graphite powder yendalo ine-lubricity elungileyo kwaye ihlala isetyenziswa njenge-additive kwi-oyile yokuthambisa. Ukuhambisa i-corrosive medium, amakhonkco episton, amakhonkco okutywina kunye neebheringi ezenziwe ngomgubo wegraphite eyenziweyo zisetyenziswa ngokubanzi, ngaphandle kokongeza ioyile yokuthambisa xa isebenza. I-graphite powder yendalo kunye ne-polymer resin composite nazo zingasetyenziswa kule mihlaba ingasentla, kodwa ukuxhathisa ukunxiba akulunganga njengomgubo wegraphite eyenziweyo.
3. Ishishini lemichiza
Umgubo wegraphite owenziweyo uneempawu zokuxhathisa umhlwa, ukuhanjiswa kakuhle kwe-thermal, ukunyanzeliswa okuphantsi, kwaye isetyenziswa kakhulu kwishishini lemichiza ukwenza umtshintshi wobushushu, itanki yokusabela, inqaba yokufunxa, isihluzo kunye nezinye izixhobo. I-graphite powder yendalo kunye ne-polymer resin composite izinto nazo zingasetyenziswa kule mihlaba ingasentla, kodwa i-thermal conductivity, ukumelana ne-corrosion ayilungile njengomgubo wegraphite eyenziweyo.
Ngokuphuhliswa kobuchwepheshe bophando, ithemba lokusetyenziswa kwe-graphite powder eyenziweyo ayinakulinganiswa. Okwangoku, ukusebenzisa igraphite yendalo njengento ekrwada ukuphuhlisa iimveliso zegraphite yokwenziwa kunokuthathwa njengenye yeendlela ezibalulekileyo zokwandisa intsimi yesicelo segraphite yendalo. I-powder ye-graphite yendalo isetyenziswe njengento encedisayo ekrwada ekuveliseni enye i-graphite powder eyenziwe, kodwa akwanelanga ukuphuhlisa iimveliso zegraphite ezenziweyo kunye ne-graphite powder yendalo njengeyona nto iphambili. Indlela efanelekileyo yokuqonda le njongo kukusebenzisa ngokupheleleyo isakhiwo kunye neempawu ze-graphite powder yendalo, kunye nokuvelisa iimveliso zegraphite ezenziweyo kunye nesakhiwo esikhethekileyo, ukusebenza kunye nokusetyenziswa ngeteknoloji efanelekileyo, indlela kunye nendlela.
