Graphite ufa uli ndi ntchito zosiyanasiyana, ndipo malinga ndi ntchito zake zosiyanasiyana, titha kugawa ufa wa graphite muzotsatira zotsatirazi:

1. Nano graphite ufa
Kufotokozera kwakukulu kwa nano graphite ufa ndi D50 400 nanometers.Njira ya nano graphite powder ndi yovuta kwambiri ndipo mtengo wake ndi wotsika, choncho mtengo wake ndi wokwera kwambiri.Amagwiritsidwa ntchito makamaka m'mafakitale monga zokutira zotsutsana ndi dzimbiri, zopangira mafuta opaka mafuta, zopangira mafuta opaka mafuta, ndi zosindikizira zolondola za graphite.Kuphatikiza apo, ufa wa nano graphite ulinso ndi phindu lalikulu m'mabungwe ofufuza asayansi.

2. Colloidal graphite ufa
Colloidal graphite imapangidwa ndi 2 μ Tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono tomwe timamwazikana mu zosungunulira za organic kupanga colloidal graphite, yomwe ndi madzi akuda ndi ma viscous oyimitsidwa.Colloidal graphite ufa uli ndi mawonekedwe apamwamba kwambiri achilengedwe a flake graphite, ndipo ali ndi kukana kwapadera kwa okosijeni, kudzipangira okha mafuta komanso pulasitiki pansi pa kutentha kwambiri.Panthawi imodzimodziyo, imakhala ndi conductivity yabwino, kutentha kwa kutentha ndi kumamatira, ndipo imagwiritsidwa ntchito makamaka m'mafakitale monga kusindikiza ndi kugwetsa zitsulo.

3. Flake graphite ufa
Kugwiritsa ntchito ufa wa flake graphite ndikokwanira kwambiri, komanso ndizomwe zimagwiritsidwa ntchito popanga ma graphite ena.Mafotokozedwe ake amachokera ku 32 mpaka 12000 mesh, ndipo flake graphite ufa uli ndi kulimba kwabwino, matenthedwe amatenthedwe, komanso kukana dzimbiri.Itha kugwiritsidwa ntchito ngati zida zodzitchinjiriza, zosagwira komanso zopaka mafuta, zida zowongolera, kuponyera, kutembenuza mchenga, kuumba, ndi zitsulo zotentha kwambiri.

4. Ultrafine graphite ufa
Mafotokozedwe a ufa wa ultrafine graphite nthawi zambiri amakhala pakati pa 1800 ndi 8000 mauna, omwe amagwiritsidwa ntchito kwambiri ngati othandizira pobowola muzitsulo za ufa, kupanga ma graphite crucibles, maelekitirodi olakwika a mabatire, ndi zowonjezera pazinthu zoyendetsera.

China ili ndi nkhokwe zambiri za graphite yachilengedwe.Posachedwapa, ndondomeko ya mphamvu yatsopano yomwe idakhazikitsidwa ndi dzikolo yakhala ikugwiritsidwa ntchito mokwanira, ndipo ntchito yozama yopangira ma graphite achilengedwe idzakhala yofunika kwambiri.M'zaka zikubwerazi, kufunikira kwa mafoni a m'manja, makompyuta, magalimoto amagetsi, ndi magalimoto amagetsi kudzapitirira kukula, zomwe zimafuna mabatire ambiri a lithiamu monga gwero la mphamvu.Monga electrode yoyipa ya mabatire a lithiamu, kufunikira kwa ufa wa graphite kudzawonjezeka kwambiri, zomwe zidzabweretse mwayi wopita patsogolo mofulumira ku mafakitale a ufa wa graphite.
