Xa i-flake yegraphite ikhuhla isinyithi, ifilimu yegraphite yenziwa kumphezulu wesinyithi kunye ne-flake graphite, kwaye ubukhulu bayo kunye neqondo lokuqhelaniswa nokufikelela kwixabiso elithile, oko kukuthi, i-flake graphite inxiba ngokukhawuleza ekuqaleni, kwaye emva koko yehla kwixabiso elingaguqukiyo. Indawo ecocekileyo yentsimbi yegraphite inomkhombandlela ongcono, ubukhulu befilimu yekristale encinci, kunye nokunamathela okukhulu. Lo mmandla wokungqubuzana unokuqinisekisa ukuba izinga lokunxiba kunye nedatha ye-friction incinci de kube sekupheleni kokubambisana. Lo mhleli ulandelayo we-FRT wegraphite uhlalutya ukunxitywa kwezinto ze-flake graphite:
I-Flake graphite ine-conductivity ephezulu ye-thermal, enceda ukuhambisa ubushushu ngokukhawuleza ukusuka kwi-friction surface, ukwenzela ukuba iqondo lokushisa ngaphakathi kwezinto kunye ne-friction surface likwazi ukulingana. Ukuba uxinzelelo luqhubeka lusanda, ifilimu yegraphite ejoliswe kuyo iya konakaliswa kakhulu, kwaye izinga lokuguga kunye ne-friction coefficient iya kwanda ngokukhawuleza. Kwimiphezulu eyahlukeneyo yentsimbi yegraphite, kuzo zonke iimeko, ukuphakama koxinzelelo oluvumelekileyo, kokukhona ukuqhelaniswa kwefilimu yegraphite eyenziwe kumphezulu wokukhuhla. Kwi-air medium kunye nobushushu be-300 ~ 400 degrees, ngamanye amaxesha i-coefficient ye-friction iyanda ngenxa ye-oxidation enamandla ye-flake graphite.
Ukuziqhelanisa kubonise ukuba i-graphite ye-flake iluncedo kakhulu ekungathathi hlangothi okanye ekunciphiseni imidiya kunye nokushisa kwe-300-1000 degrees. I-graphite ekwazi ukumelana nezixhobo ezifakwe ngesinyithi okanye i-resin ilungele ukusebenza kwindawo yegesi okanye i-liquid medium kunye nomswakama we-100%, kodwa ubushushu bokusetyenziswa kwayo buthintelwe kukumelana nobushushu be-resin kunye nendawo yokunyibilika kwe-resin. intsimbi.
