Ekushiseni okuphezulu, i-graphite enwetshiwe iyanda ngokushesha, okuvimbela ilangabi. Ngasikhathi sinye, impahla enwetshiwe ekhiqizwa yiyo imboza ingaphezulu le-substrate, elihlukanisa imisebe eshisayo kusuka koxhumana naye onomoya-mpilo kanye ne-acid free radicals. Lapho kukhula, ingaphakathi le-interlayer liyanda futhi, futhi ukukhululwa kukhuthaza nokukhuthaza i-carbonization ye-substrate, ngaleyo ndlela kufinyelele imiphumela emihle ngezindlela ezahlukahlukene ze-flame retardant. Isihleli esilandelayo segrafu furuite sethula izinhlobo ezimbili zegrafu ezandisiwe ezisetshenziselwa ukuvimbela umlilo:
Okokuqala, okuqukethwe okunwetshiwe kwe-graphite kuxutshaniswa nezinto zenjoloba, i-accelerator, i-accelerator, i-ejenti, futhi imininingwane ehlukahlukene yeminyango yokubopha enwetshiwe yenziwa, esetshenziswa ikakhulukazi eminyango yomlilo, amafasitela omlilo nezinye izikhathi. Lo mcucu wokubopha uphawu onwetshiwe ungavimba ukuhamba kwentuthu kusukela ekuqaleni kuze kube sekupheleni kokushisa kwegumbi kanye nomlilo.
Enye ukusebenzisa i-glass fiber tape njengothwala, futhi banamathela i-graphite ethe xaxa kumthwali onamatheli athile. Ukumelana kwe-Shear okunikezwe yiCarbide okwakheke ngalo mzimba ekushiseni okuphezulu kungavimba ngempumelelo i-graphite kusuka ekulimeni. Isetshenziselwa ikakhulukazi iminyango yomlilo, kepha ayikwazi ukuvimba ngempumelelo ukugeleza kwentuthu ebandayo ekushiseni kwegumbi noma okushisa okuphansi, ngakho-ke kufanele kusetshenziswe ngokubambisana negumbi lokushisa lekamelo.
Umucu wokubopha uphawu lomlilo ngenxa yokubuyiselwa kwemali kanye nokuphikiswa okuphezulu kokushisa kwegrafu okunwetshiwe, i-graphite enwetshiwe isiphenduke into enhle kakhulu yokubopha futhi isetshenziswa kabanzi emkhakheni wokubekwa uphawu lomlilo.
