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, isigaba se-liquid silicate ngaphansi kwesenzo samandla e-capillary, singene egebeni lezinhlayiyana, ngokunamathela phakathi kwazo ukuze kuhlanganiswe izinhlayiya ze-flake ze-graphite, ekwakhekeni kongqimba lwefilimu ezungeze i-flake graphite, ngemva kokupholisa ukuze kwakhiwe i-continuum, kanye nokwakhiwa kwe-high adhesion interface ne-flake graphite. 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.
