Ipowder yegraphite luhlobo lwepowder ecocekileyo eyenziwe ngekhabhoni emva kwe-pyrolysis ephezulu yobushushu okanye i-carbonization, kunye nenxalenye yayo ephambili yikhabhoni. I-graphite powder inesakhiwo esikhethekileyo, esimnyama esimnyama okanye esimnyama esikhanyayo. Ubunzima bayo bemolekyuli yi-12.011.
Iimpawu ze-graphite powder zingashwankathelwa ngolu hlobo lulandelayo:
1. I-conductivity ephezulu kunye ne-thermal conductivity: i-graphite powder yinto efanelekileyo yokuqhuba kunye ne-thermal conductivity, kunye ne-high conductivity ye-thermal kunye ne-conductivity. Oku kubangelwa ikakhulu kulungiselelo oluqinileyo kunye nolwakhiwo lwe-athom yekhabhoni kwigraphite, eyenza kube lula ukuqhuba ii-electron kunye nobushushu.
2. I-inertness yeekhemikhali ezilungileyo: i-graphite powder inozinzo oluhle lweekhemikhali kunye ne-inertness phantsi kweemeko eziqhelekileyo, kwaye ayiphenduli ngezinto ezininzi. Kungenxa yoko le nto i-graphite powder isetyenziswa ngokubanzi kwimimandla yezixhobo ze-elektroniki kunye neekhemikhali, ukukhuselwa kwe-corrosion yeqondo lokushisa eliphezulu, njl.
3. Inamandla athile omatshini: xa kuthelekiswa nezinye i-nano-materials, i-graphite powder inefuthe eliphezulu lokuchasana, ukuxhathisa i-extrusion kunye nokumelana nokuqhekeka, okunokuphucula iimpawu zemishini yezixhobo ukuya kwinqanaba elithile.
Iindlela zokulungiselela umgubo wegraphite zahlukile, kwaye iindlela eziqhelekileyo zezi zilandelayo:
1. I-Pyrolysis kwiqondo lokushisa eliphezulu: ukushisa i-graphite yendalo okanye i-crystal synthesized graphite crystal kwiqondo lokushisa eliphezulu (ngaphezu kwe-2000 ℃) ukuyibolisa ibe ngumgubo wegraphite.
2. Indlela ye-carbonization yobushushu obuphezulu: i-graphite powder ifunyenwe yi-chemical reaction ye-graphite kunye nezinto eziluhlaza kunye nesakhiwo esine-layer efana ne-graphite. Ngokwemathiriyeli ekrwada ehlukeneyo, inokwahlulwa ngokweendlela ezahlukeneyo zokulungiselela, ezifana ne-vapor chemical deposition deposition, i-pyrolysis kunye ne-carbonization.
3. Indlela yomatshini: ngokusila ngomatshini kunye nemisebenzi yokuhlola, i-graphite yendalo okanye izinto ze-synthetic graphite zicutshungulwa ukufumana i-graphite powder.
Iindlela ezahlukeneyo zokulungiselela zineempembelelo ezahlukeneyo kumgangatho, ubunyulu kunye ne-morphology ye-graphite powder. Kwizicelo ezisebenzayo, iindlela ezifanelekileyo zokulungiselela kufuneka zikhethwe ngokweemfuno ezahlukeneyo.
1. Izinto zombane kunye neekhemikhali: i-graphite powder ingalungiswa ibe yi-conductive kunye ne-thermal conductive polymer composites, ezisetyenziswa kwizixhobo zombane, iibhetri, ii-inki ze-conductive kunye nezinye iinkalo. Ngokomzekelo, kwizinto eziphathekayo ze-electrode, i-graphite powder inokunyusa ukuqhutyelwa kwezinto, ukuphucula ukusebenza kwe-electrochemical ye-electrode, kunye nokwandisa ubomi benkonzo yebhetri.
2. Izinto zokugquma: i-graphite powder ingasetyenziselwa ukulungiswa kweengubo ezahlukeneyo, ezifana ne-anti-corrosion coating, i-thermal conductivity coating, i-electromagnetic shielding coating, njl. Kwimimandla yemoto, inqwelomoya, ukwakhiwa, njl. nge-graphite powder inokuphucula ukuxhathisa kwe-ultraviolet kunye nokumelana nokubola kwezinto.
3. I-Catalyst: I-graphite powder ingasetyenziselwa ukulungiswa kwe-catalyst, kwaye isetyenziswe ngokubanzi kwi-organic synthesis, ukuveliswa kweekhemikhali kunye nezinye iinkalo. Ngokomzekelo, kwi-hydrogenation yeoli yemifuno, i-graphite powder emva kokunyanga ingasetyenziselwa njenge-catalyst yokuphucula i-reaction selectivity kunye nesivuno.
4. Izinto zeCeramic: Ekulungiseleleni izinto ze-ceramic, i-graphite powder inokuphucula amandla ayo omatshini kunye nezinye iimpawu ngokuqinisa impembelelo. Ngokukodwa kwi-cermets kunye ne-porous ceramics, i-graphite powder isetyenziswa kakhulu.
