Marka graphite-ku uu ku xoqo birta, waxa ku samaysma filim graphite ah oogada sare ee birta iyo garaafka graphite-ka, dhumucdiisuna iyo heerka jihayntoodu waxa ay gaadhaan qiimo go'an, taas oo ah, garaafiga graphite ayaa si dhakhso ah u xidha bilowga, iyo ka dibna hoos ugu dhaco qiimaha joogtada 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 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 graphite ee kala duwan, dhammaan kiisaska, cadaadiska la oggol yahay ee sarreeya, ayaa si fiican u jihada filimka graphite ee lagu sameeyay dusha jilicsan. 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. Walaxda garaafyada u adkaysta ee lagu shubay birta ama resin waxay ku habboon tahay in lagu shaqeeyo dhexdhexaad gaas ama dhexdhexaad dareere leh huurka 100%, laakiin kala duwanaanta heerkulka isticmaalkeeda waxaa xaddiday caabbinta kulaylka resinka iyo barta dhalaalka biraha.
