Garaafyada Flake waa macdan dhif ah oo aan la cusboonaysiin karin, taas oo si weyn loogu isticmaalo warshadaha casriga ah waana kheyraad istiraatiiji ah oo muhiim ah. Midowga Yurub wuxuu liis gareeyay graphene, badeecada la dhammeeyey ee farsamaynta garaafka, mashruuc tignoolajiyada cusub ee mustaqbalka, wuxuuna garaafyada ku taxay mid ka mid ah 14 nooc oo ah "nolol-iyo-dhimasho" kheyraadka macdanta. Maraykanku waxa uu liis gareeyaa agabka garaafiga flake sida alaabta ceeriin ee muhiimka ah ee warshadaha tignoolajiyada sare. Kaydka graphite-ka ee Shiinaha ayaa ah 70% adduunka, waana kaydka graphite-ka ee ugu weyn adduunka. Si kastaba ha ahaatee, waxaa jira dhibaatooyin badan oo ku saabsan habka wax soo saarka, sida qashinka macdanta, isticmaalka hooseeya ee kheyraadka iyo waxyeellada deegaanka ee khatarta ah. Yaraanta kheyraadka iyo kharashka dibadda ee deegaanka kama tarjumayaan qiimaha dhabta ah. Dhibaatooyinka wadaagga soo socda ee tifaftirayaasha garaafyada Furuite ayaa inta badan lagu muujiyey dhinacyada soo socda:
Marka hore, cashuurta kheyraadka waxay u baahan tahay in si degdeg ah wax looga beddelo. Heerka canshuurta hooseeya: Canshuurta kheyraadka graphite ee Shiinaha hadda waa 3 yuan halkii ton, taas oo aad u fudud oo aan ka tarjumeynin yaraanta kheyraadka iyo kharashka dibadda ee deegaanka. Marka la barbar dhigo dhulalka dhifka ah ee leh yaraanta macdanta iyo muhiimadda la midka ah, ka dib dib-u-habaynta cashuurta kheyraadka dhulka ee dhifka ah, ma aha oo kaliya alaabooyinka canshuuraha ayaa si gaar ah loo taxay, laakiin sidoo kale heerka canshuurta ayaa kor loo qaaday in ka badan 10 jeer. Marka la barbardhigo, heerka canshuurta kheyraadka ee graphite flake waa hooseeyaa. Hal cashuureed: Xeerarka ku meel gaadhka ah ee cashuurta khayraadku waxa ay leeyihiin hal cashuur oo ah graphite ore, taas oo aan loo qaybin si waafaqsan darajada tayada iyo nooca garaafka, kamana tarjumayso shaqada cashuurta kheyraadka ee nidaaminta dakhliga kala duwan. Waa wax aan cilmi ahayn in lagu xisaabiyo mugga iibka: waxaa lagu xisaabiyaa mugga iibka, ma aha qaddarka dhabta ah ee macdanta la qoday, iyada oo aan la tixgelinayn magdhowga waxyeellada deegaanka, horumarinta macquulka ah ee kheyraadka, kharashka horumarinta iyo daalka kheyraadka.
Marka labaad, dhoofintu aad bay u degdegsan tahay. Shiinaha waa soo saaraha ugu weyn adduunka ee garaafyada flake dabiiciga ah, waligiisna waa dhoofinta ugu weyn ee alaabta garaafyada dabiiciga ah. Si aad ah uga soo horjeeda Shiinaha ee ka faa'iidaysiga xad-dhaafka ah ee khayraadka graphite, dalalka horumaray, kuwaas oo hogaaminaya in technology ee alaabta processing qoto dheer graphite, hirgeliyaan istaraatijiyad ah "iibsashada halkii macdanta" graphite dabiiciga ah iyo xannibi technology. Sida suuqa ugu weyn ee garaafyada ee Shiinaha, wax soo dejinta Japan ayaa ah 32.6% wadarta dhoofinta Shiinaha, iyo qayb ka mid ah macdanta graphite-ka ee la soo dejiyo waxay ku degtaa sariirta badda; Dhanka kale, Kuuriyada Koonfureed, waxay xirtay miinada graphite-ka waxayna soo dejisay tiro badan oo alaab ah oo qiimo jaban ah; Mugga soo dejinta sannadlaha ah ee Maraykanku wuxuu xisaabiyaa qiyaastii 10.5% wadarta guud ee dhoofinta Shiinaha, kheyraadkiisa garaafka waxaa ilaaliya sharci.
Saddex, habayntu aad bay u ballaadhan tahay. Tilmaamaha garaafka waxay si dhow ula xiriiraan cabbirka miisaankiisa. Cabbirrada kala duwan ee graphite flake waxay leeyihiin isticmaalyo kala duwan, hababka habaynta iyo goobaha codsiga. Waqtigan xaadirka ah, waxaa jira la'aan cilmi-baaris ah oo ku saabsan tignoolajiyada graphite ore leh sifooyin kala duwan oo Shiinaha ah, iyo qaybinta agabka graphite ee leh miisaan kala duwan lama xaqiijin, mana jiro hab qotodheer oo qoto dheer oo u dhigma. Heerka soo kabashada garaafyada garaafka waa hooseeyaa, iyo dhalidda garaafyada waaweyni waa hooseeyaa. Sifooyinka kheyraadku ma cadda, habka habayntuna waa hal. Natiijo ahaan, garaafyada flake ee baaxadda weyn si wax ku ool ah looma ilaalin karo iyo garaafyada flake-yar ee aan si wax ku ool ah loo isticmaali karin inta lagu gudajiro howsha, taasoo keentay qashin weyn oo kheyraad istiraatiiji ah oo qiimo leh.
Afar, farqiga qiimaha u dhexeeya soo dejinta iyo dhoofinta waa cajiib. Inta badan alaabooyinka garaafyada dabiiciga ah ee dabiiciga ah ee laga soo saaro Shiinaha ayaa ah kuwa ugu horreeya ee la warshadeeyay, cilmi baarista iyo horumarinta iyo soosaarka alaabada qiimaha sare leh ayaa si cad u maqan. Tusaale ahaan u soo qaado garaafka saafiga ah ee sare, wadamada shisheeye waxay hogaanka u qabtaan graphite daahirnimo sare leh faa'iidooyinkooda teknoolajiyada, waxayna ku xannibaan wadankeena alaabada graphite-ka sare ee tignoolajiyada. Waqtigan xaadirka ah, tignoolajiyada garaafka nadiifka ah ee sare ee Shiinaha ayaa si dhib yar u gaari karta nadiifnimada 99.95%, nadiifnimada 99.99% ama ka badan waxay si buuxda ugu tiirsanaan kartaa soo dejinta. Sannadkii 2011, celceliska qiimaha garaafyada flake dabiiciga ah ee Shiinaha wuxuu ahaa qiyaastii 4,000 yuan / ton, halka qiimaha in ka badan 99.99% laga keenay garaafyada saafiga ah ee sarreeya uu kor u dhaafay 200,000 yuan / ton, farqiga qiimahana wuxuu ahaa mid cajiib ah.
