Iphepha legrafiti liphepha elikhethekileyo elenziwe ngegrafiti. Xa igrafiti yayisandula ukugrunjwa emhlabeni, yayifana nezikali, kwaye yayibizwa ngokuba yigrafiti yendalo. Olu hlobo lwegrafiti kufuneka luphathwe kwaye lucocwe ngaphambi kokuba lusetyenziswe. Okokuqala, igrafiti yendalo ifakwa kwisisombululo esixutyiweyo se-sulfuric acid egxininisiweyo kunye ne-nitric acid egxilileyo kangangexesha elithile, emva koko ihlanjwe ngamanzi acacileyo kwaye ibhobozwe, ize ibekwe kwisithando somlilo esishushu kakhulu ukuze sitshiswe. Umhleli wegrafiti weFuruite olandelayo uzisa imiqathango yokuvelisa.iphepha legrafayithi:
Ngenxa yokuba i-inlay phakathi kwe-graphite iyaphela ngokukhawuleza emva kokufudumeza, kwangaxeshanye, umthamo we-graphite wanda ngokukhawuleza ngamanani amaninzi okanye amakhulu amaxesha, ngoko ke kufunyanwa uhlobo lwe-graphite ebanzi, ebizwa ngokuba yi-"graphite evuvukileyo". Kukho imingxunya emininzi kwindawo evuvukileyo.igrafayithi(eshiywe emva kokuba i-inlay isusiwe), nto leyo enciphisa kakhulu uxinano lokupakisha lwe-graphite ukuya kwi-0.01 ~ 0.059/cm3, enobunzima obulula kunye nobushushu obuhle kakhulu. Ngenxa yokuba kukho imingxunya emininzi enobukhulu obahlukeneyo kunye nokuqhekeka, inokudityaniswa kunye enye kwenye ngamandla angaphandle, okuyi-self-adhesion ye-graphite eyandisiweyo. Ngokwale self-adhesion ye-graphite eyandisiweyo, ingacutshungulwa ibe liphepha le-graphite.
Ngoko ke, imfuneko yokuveliswa kwephepha legrafiti kukuba neseti epheleleyo yezixhobo, oko kukuthi, isixhobo sokulungiselela igrafiti eyandisiweyo ekuntywiliseni, ekucoceni nasekutshiseni, apho kukho amanzi nomlilo, okunokubangela ukuqhuma, ngoko ke imveliso ekhuselekileyo ibaluleke kakhulu; Okwesibini, oomatshini bokwenza iphepha kunye noomatshini bokucinezela i-roller, uxinzelelo oluhambelanayo loxinzelelo lwe-roller akufanele lube phezulu kakhulu, kungenjalo luya kuchaphazela ukufana kunye namandla ephepha legrafiti, kwaye uxinzelelo oluhambelanayo luncinci kakhulu, nto leyo engenakwenzeka nangakumbi. Ke ngoko, iimeko zenkqubo kufuneka zichaneke, kwayeigrafitiIphepha le-e liyoyika ukufuma. Iphepha eligqityiweyo kufuneka libe yipakethe engangeni manzi, khumbula ukuba lingangeni manzi kwaye ligcinwe kakuhle.
