Valani kukana zinthu za flake graphite

Pamene flake graphite ipaka chitsulo, filimu yopyapyala ya graphite imapangidwa pamwamba pa chitsulo ndi flake graphite, ndipo makulidwe ake ndi mawonekedwe ake amafika pamtengo wina, ndiko kuti, graphite ya flake imavala mwachangu pachiyambi, kenako imatsika mpaka kusinthasintha. mtengo. Pamwamba pazitsulo zoyera za graphite zimakhala ndi mawonekedwe abwinoko, makulidwe ang'onoang'ono a filimu ya kristalo ndi zomatira zazikulu. Kukangana kumeneku kumatha kuonetsetsa kuti kuchuluka kwa mavalidwe ndi deta yachangu ndi yaying'ono kumapeto kwa kukangana. Mkonzi wotsatira wa Furuite Graphite amakutengerani kuti muwunike zinthu zotsutsana ndi ma flake graphite:

Graphite imakhala ndi matenthedwe apamwamba kwambiri, omwe amathandizira kusamutsa kutentha mwachangu kuchokera kumtunda, kotero kuti kutentha mkati mwazinthu ndi kugwedezeka kwake kumakhala koyenera. Ngati kupanikizika kukupitirirabe, filimu ya graphite yokhazikika idzawonongeka kwambiri, ndipo kuchuluka kwa mavalidwe ndi friction coefficient idzawonjezekanso mofulumira. Pamalo osiyanasiyana amakangana achitsulo a graphite, nthawi zonse, kuthamanga kwapamwamba kovomerezeka, kumapangitsa kuti filimu ya graphite ipangidwe pamtunda wokangana bwino. Mu mpweya sing'anga ndi kutentha kwa 300 ~ 400 ℃, nthawi zina mikangano coefficient amachulukira chifukwa cha makutidwe ndi okosijeni wamphamvu wa flake graphite.

Zoyeserera zikuwonetsa kuti graphite ya flake ndiyothandiza kwambiri pakusalowerera ndale kapena kuchepetsa media ndi kutentha kwa 300 ~ 1000 ℃. graphite kuvala zosagwira zakuthupi impregnated ndi zitsulo kapena utomoni ndi oyenera ntchito gasi kapena madzi sing'anga ndi chinyezi 100%, koma ntchito yake kutentha osiyanasiyana amaletsedwa ndi kutentha kukana utomoni ndi malo osungunuka zitsulo.
