Ukungezwani okungaphezulu kwe-flake graphite kuncane, akukho sici endaweni enkulu, futhi kukhona cishe u-0.45% wezinto eziphilayo eziguquguqukayo ebusweni be-flake graphite, konke okona ukumanzisa kwe-flake graphite. I-hydrophobicity eqinile ebusweni be-flake graphite yenza kube kubi kakhulu ukuchithwa kwe-castable, futhi i-flake graphite ijwayele ukuhlangana kunokuba ihlakazeke ngokulinganayo endaweni ephikisayo, ngakho-ke kunzima ukulungisa i-amorphous refractory efanayo neminyene. Uchungechunge oluncane olulandelayo lwe-Furuite graphite analysis of the wettability and application limitations of flake graphite:
Faka i-graphite
I-microstructure kanye nezakhiwo ze-flake graphite ngemva kokushisa okuphezulu kwe-sintering kunqunywa kakhulu ukumanzisa koketshezi lwe-silicate okushisa kuya ku-flake graphite. Lapho ukumanzisa, silicate liquid isigaba ngaphansi isenzo amandla capillary, singene igebe kuyizinhlayiyana, by the adhesion phakathi kwabo ukubopha izinhlayiya flake graphite, ekwakhekeni ungqimba ifilimu ezizungeze i-flake graphite, ngemva kokupholisa ukuze kwakhiwe continuum, kanye nokwakheka high adhesion interface nge graphite flake. Uma lezi zibili zingamanziswanga, izinhlayiya ze-flake ze-graphite zakha ama-aggregates, futhi isigaba se-silicate liquid sivalelwe igebe lezinhlayiyana futhi sakha umzimba ongawodwa, okunzima ukwenza inkimbinkimbi eminyene ngaphansi kokushisa okuphezulu.
Ngakho-ke, i-Furuite graphite yaphetha ngokuthi ukumanzisa kwe-flake graphite kufanele kuthuthukiswe ukuze kulungiselelwe ama-carbon refractories amahle kakhulu.
