Iphepha legraphite liphepha elikhethekileyo elicutshungulwa kwigraphite njengezinto eziluhlaza. Xa i<em>graphite yayisandul’ ukugrunjwa emhlabeni, yayifana nje namaxolo, yaye ithambile yaye yayibizwa ngokuba yi<em>graphite yendalo. Le graphite kufuneka icutshungulwe kwaye icocwe ukuze ibe luncedo. Okokuqala, cwilisa i-graphite yendalo kumxube we-sulfuric acid egxininisiweyo kunye ne-nitric acid egxininisiweyo ixesha elithile, emva koko uyikhuphe, uhlambulule ngamanzi, uyomise, uze uyibeke kwisithando somlilo esiphezulu sokutshisa. Lo mhleli ulandelayo weFuruite graphite wazisa izinto ezifunekayo zokwenziwa kwephepha legraphite:
Ngenxa yokuba i-inlays phakathi kweegrafu iyancipha ngokukhawuleza emva kokufudumala, kwaye kwangaxeshanye, umthamo wegraphite ukhula ngokukhawuleza ngamaninzi okanye namakhulu amaxesha, ngoko ke kufunyenwe uhlobo lwegraphite ebanzi, ebizwa ngokuba "yigraphite eyandisiweyo". Kukho imingxuma emininzi (esele emva kokuba i-inlays isusiwe) kwi-graphite eyandisiweyo, eyanciphisa kakhulu ubuninzi be-graphite, eyi-0.01-0.059 / cm3, i-light inweight kunye negqwesileyo kwi-insulation heat. Ngenxa yokuba kukho imingxunya emininzi, ubukhulu obahlukeneyo, kunye nokungalingani, banokuwelana omnye nomnye xa kusetyenziswa amandla angaphandle. Oku kukuzincamathela kwegraphite eyandisiweyo. Ngokwe-self-adhesion ye-graphite eyandisiweyo, inokucutshungulwa ibe yiphepha legraphite.
Ngoko ke, imfuneko yokuveliswa kwephepha legraphite kufuneka ibe nesethi epheleleyo yezixhobo, oko kukuthi, isixhobo sokulungiselela igraphite eyandisiweyo ukusuka ekucwilisweni, ukucoca, ukutshisa, njl., apho kukho amanzi kunye nomlilo. Ibaluleke ngakumbi; okwesibini kukwenza iphepha kunye nokucofa umatshini we-roller. Ukunyanzeliswa komgca we-roller yokucinezela akufanele kube phezulu kakhulu, ngaphandle koko kuya kuchaphazela ukulingana kunye namandla ephepha legraphite, kwaye ukuba uxinzelelo lomgca luncinci kakhulu, alumkelekanga ngakumbi. Ngoko ke, iimeko ezicwangcisiweyo zenkqubo kufuneka zichaneke, kwaye iphepha legraphite loyika umswakama, kwaye iphepha eligqityiweyo kufuneka lifakwe kwi-package-proof package kwaye ligcinwe ngokufanelekileyo.
