Izakhiwo zamakhemikhali ezinhle kakhulu ze-flake graphite

I-graphite yemvelo ye-flakeingahlukaniswa ibe yi-crystalline graphite ne-cryptocrystalline graphite. I-crystalline graphite, eyaziwa nangokuthi i-scaly graphite, i-scaly ne-crystalline graphite evulekile. Uma isikali sikhulu, inani lezomnotho liyakhuphuka. Isakhiwo esinezingqimba sawoyela we-flake graphite engine lubricity, softness, heat resistance and conductivity kagesi kunamanye ama-graphite, futhi senziwa ikakhulukazi ngemikhiqizo ye-graphite ehlanzekile kakhulu. Umhleli olandelayo we-Furuite Graphite wethula izici ezinhle kakhulu zamakhemikhali ze-fine flake graphite:

I-flake graphite ifana ne-flake, i-crystalline encane njengeqabungai-graphite, enosayizi (1.0 ~ 2.0) × (0.5 ~ 1.0) mm, ukujiya okungu-4 ~ 5 mm nogqinsi luka-0.02 ~ 0.05 mm.. Uma isikali sikhulu, inani lezomnotho liyakhuphuka. Iningi lazo lisatshalaliswa futhi lifana ne-hemp lisakazwe emadwaleni, ngokuhlelwa okucacile kokuqondisa, okuhambisana nesiqondiso sendiza yokulala. Okuqukethwe kwe-flake graphite ngokuvamile ku-3% ~ 10%, nokuphakama okungaphezu kuka-20%. Ivamise ukuhlotshaniswa namaminerali afana ne-Shi Ying, i-feldspar kanye ne-diopside emadwaleni e-metamorphic yasendulo (i-schist ne-gneiss), futhi ingabonakala endaweni yokuxhumana phakathi kwamadwala avuthayo kanye ne-limestone. I-Scaly graphite inesakhiwo esinezingqimba, futhi ukuthambisa kwayo, ukuguquguquka, ukumelana nokushisa kanye nokusebenza kukagesi kungcono kunamanye amagraphite. Isetshenziswa kakhulu njengempahla eluhlaza yokwenza imikhiqizo ye-graphite ephezulu yokuhlanzeka.

Ngokusho kokuqukethwe kwekhabhoni ehleliwe, i-flake graphite ingahlukaniswa ngezigaba ezine: i-high purity graphite, i-carbon ephezulu.i-graphite, i-carbon graphite ephakathi ne-carbon graphite ephansi. I-graphite yokuhlanzeka okuphezulu isetshenziswa kakhulu njengezinto zokuvala uphawu ze-graphite eziguquguqukayo esikhundleni se-platinum crucible yokuncibilika kwe-reagent yamakhemikhali kanye nezinto eziyisisekelo zokuthambisa. I-carbon graphite ephezulu isetshenziswa ikakhulukazi kuma-refractories, izinto eziyisisekelo zokugcoba, ibhulashi izinto ezingavuthiwe, imikhiqizo ye-carbon kagesi, izinto zokusetshenziswa zebhethri nokunye. I-Medium carbon graphite isetshenziswa kakhulu kuma-crucibles, ama-refractories, izinto zokuphonsa, i-casting coatings, izinto zokusetshenziswa zepensela, izinto zokusetshenziswa zebhethri namafutha. I-carbon graphite ephansi isetshenziselwa ikakhulukazi ukuphonsa izigqoko.
