Coke yepetroleum ine grafiti inopawo simba rakanaka remuchina, zvichiita kuti irambe yakasimba munzvimbo dzinonetsa. Haikuvadzi, zvichiita kuti igare kwenguva refu. Muindasitiri yesimbi, chinhu chakakosha pakugadzira alloys nesimbi dzemhando yepamusoro. Inobatsira mukuwana hunhu hwemakemikari nemuviri hunodiwa hwezvigadzirwa zvekupedzisira. Hunhu hwe graphitized petroleum coke hunogona kusiyana zvichienderana nezvinhu zvakaita sekwakabva petroleum uye matekiniki ekugadzirisa anoshandiswa. Magiredhi emhando yepamusoro ndiwo anofarirwa pakushandiswa kwakakosha. Uyezve, kuwanikwa kwayo uye mutengo wayo wakaderera zvinoita kuti ive sarudzo inoshanda kumaindasitiri mazhinji. Chinhu chakakosha mukugadzirwa kwezvinhu zvakasiyana-siyana zvemaindasitiri, zvichibatsira mukukura nekusimudzira zvikamu zvakasiyana. Kazhinji, graphitized petroleum coke chinhu chakakosha chine mashandisirwo akasiyana-siyana, nekuda kwemusanganiswa wayo wezvinhu zvakasiyana uye basa rayo mukutsigira maitiro emaindasitiri.
