Izakhiwo zamakhemikhali ezinhle kakhulu ze-graphite ye-flake

I-graphite yemvelo ye-flakeingahlukaniswa nge-crystalline graphite kanye ne-cryptocrystalline graphite. I-crystalline graphite, eyaziwa nangokuthi i-scaly graphite, iyi-scaly ne-flaky crystalline graphite. Uma isikali sikhulu, kulapho inani lezomnotho liphakama khona. Isakhiwo esihlanganisiwe sikawoyela wenjini ye-flake graphite sinokuthambisa okungcono, ukuthamba, ukumelana nokushisa kanye nokuqhuba kukagesi kunezinye i-graphite, futhi ikakhulukazi yenziwe ngezinto zokusetshenziswa zemikhiqizo ye-graphite emsulwa kakhulu. Umhleli olandelayo we-Furuite Graphite wethula izakhiwo zamakhemikhali ezinhle kakhulu ze-fine flake graphite:

I-graphite ye-flake ifana ne-flake, i-crystalline encane efana neqabungai-graphite, enosayizi ongu-(1.0 ~ 2.0) × (0.5 ~ 1.0) mm, ubukhulu obungu-4 ~ 5 mm kanye nobukhulu obungu-0.02 ~ 0.05 mm.. Uma isikali sikhulu, kulapho inani lezomnotho liphakama khona. Iningi lazo lisakazwa futhi lifana ne-hemp lisatshalaliswa emadwaleni, ngokuhlelwa okusobala kokuqondisa, okuhambisana nokuqondisa kwendiza yokulala. Okuqukethwe kwe-flake graphite ngokuvamile kungu-3% ~ 10%, ukuphakama okungaphezu kuka-20%. Ivame ukuhlotshaniswa namaminerali afana ne-Shi Ying, i-feldspar kanye ne-diopside emadwaleni asendulo e-metamorphic (schist kanye ne-gneiss), futhi ingabonakala futhi endaweni yokuxhumana phakathi kwamadwala angenalutho kanye ne-limestone. I-scaly graphite inesakhiwo esinezingqimba, futhi ukuthambisa kwayo, ukuguquguquka, ukumelana nokushisa kanye nokuqhuba kukagesi kungcono kunezinye i-graphite. Isetshenziswa kakhulu njengezinto zokusetshenziswa zokwenza imikhiqizo ye-graphite ehlanzekile kakhulu.

Ngokusho kokuqukethwe kwekhabhoni okuhleliwe, i-flake graphite ingahlukaniswa ngezigaba ezine: i-graphite emsulwa kakhulu, i-carbon ephezului-graphite, i-graphite yekhabhoni ephakathi nendawo kanye ne-graphite yekhabhoni ephansi. I-graphite ehlanzekile kakhulu isetshenziswa kakhulu njengezinto zokuvala i-graphite eziguquguqukayo esikhundleni se-platinum crucible yokuncibilikisa i-reagent yamakhemikhali kanye nezinto eziyisisekelo zokugcoba. I-graphite yekhabhoni ephezulu isetshenziswa kakhulu ezintweni ezivimbela ukugqwala, izinto eziyisisekelo zokugcoba, izinto zokusetshenziswa kwebhulashi, imikhiqizo yekhabhoni kagesi, izinto zokusetshenziswa kwebhethri njalo njalo. I-graphite yekhabhoni ephakathi nendawo isetshenziswa kakhulu ezintweni ezivimbela ukugqwala, izinto ezivimbela ukugqwala, izinto zokusetshenziswa kwepensela, izinto zokusetshenziswa kwebhethri kanye namafutha. I-graphite yekhabhoni ephansi isetshenziswa kakhulu ezintweni ezivimbela ukugqwala.
