I-graphite powder ineepropati ezininzi ezibalaseleyo, ngoko isetyenziswa ngokubanzi kwi-metallurgy, oomatshini, umbane, iikhemikhali, iingubo, ukhuselo lwesizwe kunye namanye amacandelo oshishino. Iinkalo zokusetyenziswa kwe-graphite powder yendalo kunye ne-artificial graphite powder zineendawo zombini ezidlulayo kunye nokwahlukana. Umhleli we-Furuite graphite ulandelayo wazisa imimandla yokusetyenziswa komgubo wegraphite kunye nomgubo wegraphite eyenziweyo.
1. Ishishini lesinyithi
Kwishishini le-metallurgical, i-graphite powder yendalo ingasetyenziselwa ukuvelisa izinto eziphikisayo ezifana nezitena ze-magnesia-carbon kunye nezitena ze-aluminium-carbon ngenxa yokumelana kwayo kakuhle ne-oxidation. Umgubo wegraphite ongeyonyani unokusetyenziswa njenge-electrode yokwenza intsimbi, kodwa i-electrode eyenziwe nge-graphite powder yendalo kunzima ukuyisebenzisa kwiziko lombane elenziwe ngentsimbi elineemeko zokusebenza ezinzima.
2. Ishishini loomatshini
Kwishishini loomatshini, izinto zegraphite zihlala zisetyenziswa njengezinto ezinganxibi kunye nezinto zokuthambisa. Izinto zokuqala ekrwada ukulungiselela igraphite ekwandiswayo yi-high-carbon flake graphite, kunye nezinye ii-reagents imichiza ezifana concentrated sulfuric acid (ngaphezu 98%), ihydrogen peroxide (ngaphezu 28%), potassium permanganate, njl. ii-reagents. Amanyathelo aqhelekileyo okulungiselela ami ngolu hlobo lulandelayo: kwiqondo lokushisa elifanelekileyo, imilinganiselo eyahlukeneyo yesisombululo se-hydrogen peroxide, i-graphite yendalo ye-flake kunye ne-sulfuric acid egxininisiweyo yongezwa kwiinkqubo ezahlukeneyo, iphendule ixesha elithile phantsi kokuvuselela rhoqo, emva koko ihlanjwe ngamanzi de ingathathi hlangothi, kwaye iphakathi. Emva kokuphelelwa ngamanzi emzimbeni, yomiswa ngevacuum kwi-60 °C. I-graphite powder yendalo ine-lubricity elungileyo kwaye ihlala isetyenziswa njenge-additive ye-oyile yokuthambisa. Izixhobo zokuhambisa i-corrosive medium zisebenzisa kakhulu amakhonkco episton, amakhonkco okutywina kunye neebheringi ezenziwe ngomgubo wegraphite eyenziweyo, kwaye akufuneki ukuba wongeze ioyile yokuthambisa ngexesha lokusebenza. I-graphite powder yendalo kunye ne-polymer resin composite materials nazo zingasetyenziswa kule mimandla ingasentla, kodwa ukuxhathisa ukunxiba akulunganga njengaleyo yomgubo wegraphite eyenziweyo.
3. Ishishini lemichiza
Ipowder yokwenziwa kwegraphite ineempawu zokumelana nokugqwala, i-conductivity entle ye-thermal kunye ne-permeability ephantsi. Isetyenziswa ngokubanzi kushishino lweekhemikhali ukwenza ukutshintshiselana kobushushu, iitanki zokusabela, iinqaba zokufunxa, izihluzi kunye nezinye izixhobo. I-graphite powder yendalo kunye ne-polymer resin composite izinto nazo zingasetyenziswa kule mihlaba ingentla, kodwa i-thermal conductivity kunye ne-corrosion resistance and corrosion as good as those of artificial graphite powder.
Ngophuhliso oluqhubekayo lweteknoloji yophando, ithemba lesicelo se-graphite powder eyenziweyo ayinakulinganiswa. Okwangoku, ukuphuhliswa kweemveliso zegraphite ezenziweyo kunye negraphite yendalo njengento ekrwada yenye yeendlela ezibalulekileyo zokwandisa intsimi yesicelo segraphite yendalo. I-graphite powder yendalo njengento encedisayo ekrwada iye yasetyenziswa ekuveliseni umgubo we-graphite eyenziweyo, kodwa ukuphuhliswa kweemveliso ze-graphite ezenziweyo kunye ne-graphite powder yendalo njengeyona nto iphambili ekrwada ayanelanga. Yeyona ndlela ilungileyo yokufezekisa le njongo ngokuqonda ngokupheleleyo kunye nokusetyenziswa kwesakhiwo kunye neempawu ze-graphite powder yendalo, kunye nokwamkela iinkqubo ezifanelekileyo, iindlela kunye neendlela zokuvelisa iimveliso zegraphite ezenziweyo kunye nesakhiwo esikhethekileyo, iipropati kunye nokusetyenziswa.
