Calcined petroleum coke (PET Coke)chigadzirwa chepetroleum coke icho chakaverengerwa pakupisa kwakanyanya. Inoshandiswa mukugadzira graphite, indasitiri yekunyungudutsa, indasitiri yemakemikari, uye friction zvinhu indasitiri.

Mune friction material, Calcined petroleum coke (PET Coke)inoita basa rinokosha. Sezvo PET coke iine hunhu hwekuomarara kwakaderera uye yakakwira porosity, inonyanya kuita basa rekudzikisa kuoma kwechigadzirwa, kuderedza ruzha rwebhureki uye kudzikisa kuora kwekupisa kwezvinhu zvekukweshera pakupisa kwakanyanya mumabhureki zvinhu.

Tinogona kupa akasiyana mazinga chigadzirwa, zvakare tinofara kupa yakagadziridzwa chigadzirwa kune vatengi vedu vakuru kubva pasirese.
