Marka graphite-ku uu ku xoqo birta, filim garaaf ah ayaa ka samaysanaya dusha sare ee birta iyo garaafka graphite-ka, dhumucdiisuna iyo heerka jihayntu waxay gaadhaysaa qiime gaar ah, taas oo ah, garaafiga graphite wuxuu si dhakhso ah u xidhaa bilowga, ka dibna wuxuu ku dhacayaa qiime joogto ah. Dusha jahawareerka birta ee nadiifka ah waxay leedahay hanuunin wanaagsan, dhumucdiisuna waxay yar tahay filimka crystal, iyo adhesion weyn. Dusha sare ee is jiid jiidka ayaa hubin kara in heerka xidhashada iyo xogta khilaafku ay yar yihiin ilaa dhamaadka khilaafku. Tifaftiraha garaafyada ee FRT ee soo socda ayaa falanqeynaya arrimaha iska caabbinta xirashada ee garaafiga flake:
Garaafiga Flake wuxuu leeyahay kororka kulaylka sare, kaas oo ka caawiya in uu si dhakhso ah ugu wareejiyo kulaylka oogada dusheeda, si heerkulka gudaha alaabta iyo dusha sare ee jeexjeexu u dheellitiraan. Haddii cadaadisku sii socdo inuu sii kordho, filimka garaafka ku jihaysan aad buu u dhaawacmi doonaa, heerka xidhashada iyo isku xidhka isku xidhka ayaa sidoo kale si degdeg ah u kordhi doona. Meelaha kala duwan ee birta garaafyada ee kala duwan, dhammaan kiisaska, cadaadiska sare ee la oggol yahay, ayaa si fiican u jihada filimka graphite ee lagu sameeyay dusha sare ee xoqidda. Dhexdhexaadiyaha hawada oo leh heerkul ah 300 ~ 400 digrii, mararka qaarkood isku-xirnaanta isdhaafka ayaa kordha sababtoo ah oksaydhka xooggan ee graphite flake.
Ku celcelinta ayaa muujisay in garaafyada flake ay si gaar ah faa'iido u leedahay dhexdhexaadnimada ama yaraynta warbaahinta heerkulka 300-1000 darajo. Qalabka garaafyada u adkaysta ee lagu shubay birta ama resin waxay ku habboon tahay in lagu shaqeeyo dhexdhexaadiyaha gaaska ama dhexdhexaadiyaha dareeraha ah ee leh huurka 100%, laakiin cabbirka heerkulka isticmaalkiisa waxaa xaddiday caabbinta kulaylka ee resinka iyo barta dhalaalka ee birta.
