Kunyowa kwa flake graphite ndi kuchepa kwa ntchito yake

Pamwamba pa zovuta za flake graphite ndi zazing'ono, palibe chilema m'dera lalikulu, ndipo pali pafupifupi 0,45% osasunthika organic mankhwala padziko flake graphite, amene onse kuwonongeka wettability wa flake graphite. Amphamvu hydrophobicity padziko flake graphite worsens ndi fluidity wa castable, ndi flake graphite amakonda akaphatikiza osati kumwazikana wogawana mu refractory, choncho n'zovuta kukonzekera yunifolomu ndi wandiweyani amorphous refractory. Zotsatirazi zing'onozing'ono za Furuite graphite kusanthula kwa wettability ndi malire ntchito ya flake graphite:

Chojambula cha graphite

The microstructure ndi katundu wa flake graphite pambuyo mkulu kutentha sintering makamaka mtima ndi wettability wa mkulu kutentha silicate madzi kuti flake graphite. Pamene wetting, silicate madzi gawo pansi pa zochita za capillary mphamvu, mu tinthu kusiyana, ndi adhesion pakati pawo kugwirizana ndi flake graphite particles, mu mapangidwe wosanjikiza filimu padziko flake graphite, pambuyo yozizira kupanga continuum, ndi mapangidwe mkulu adhesion mawonekedwe ndi flake graphite. Ngati awiriwo sali wonyowa, flake graphite particles kupanga aggregates, ndi silicate madzi gawo ali m'mphepete tinthu kusiyana ndi kupanga akutali thupi, amene n'zovuta kupanga wandiweyani zovuta kutentha.

Choncho, Furuite graphite anaganiza kuti wettability wa flake graphite ayenera kusintha kuti akonze bwino mpweya refractories.
