Izinqubo zokukhiqiza izimo ezifakwe emanzini
Ukufutha kuyisigaba sokuzikhethela esenziwayo ukuze kuthuthukiswe izakhiwo zomkhiqizo wokugcina. Ama-tar, ama-pitches, ama-resin, izinsimbi ezincibilikisiwe kanye nezinye izinto ezisetshenziswayo zingafakwa ezimweni ezibhakiwe (ezisetshenzisweni ezikhethekile, izimo ze-graphite nazo zingafuthwa) kanti ezinye izinto ezisetshenziswayo zisetshenziselwa ukugcwalisa izikhala ezakhiwe ezintweni ezifakwe i-carbonised. Ukufutha nge-hot coal tar pitch nge-vacuum noma ngaphandle kwayo kanye ne-autoclaving kuyasetshenziswa. Kusetshenziswa amasu ahlukahlukene okufutha kuye ngomkhiqizo ofana nokuthi kusetshenziswa imisebenzi ye-batch noma eqhubekayo. Umjikelezo wokufutha uvame ukuhilela ukushisa kusengaphambili izimo, ukufutha kanye nokupholisa. I-reactor yokuqinisa ingasetshenziswa futhi. Ama-electrode okumele afuthwa angashiswa ngokushisa okungcolile kwe-thermal oxidiser. Ama-carbon akhethekile kuphela afuthwa ngezinsimbi ezahlukahlukene. Izingxenye ezibhakiwe noma ezifakwe i-graphiti zingafuthwa ngezinye izinto, isib. Ama-resin noma izinsimbi. Ukufutha kwenziwa ngokucwilisa, ngezinye izikhathi ngaphansi kwe-vacuum futhi ngezinye izikhathi ngaphansi kwengcindezi, kusetshenziswa ama-autoclave. Izakhi ezifakwe noma eziboshwe nge-coal tar pitch ziyabhakwa futhi. Uma kusetshenziswe i-resin bonding, ziyaphola.
Izinqubo zokukhiqiza izimo ezibhakiwe kabusha ezivela ezimweni ezifakwe emanzini
Ukubhaka nokubhaka kabusha Ukubhaka kabusha kusetshenziselwa kuphela izimo ezifakwe emanzini. Izimo eziluhlaza (noma izimo ezifakwe emanzini) zibhakwa kabusha emazingeni okushisa afinyelela ku-1300 °C kusetshenziswa izinhlobo ezahlukene zezitofu ezifana nomhubhe, igumbi elilodwa, igumbi eliningi, izitofu ze-annular kanye ne-push rod kuye ngobukhulu kanye nobunzima bomkhiqizo. Ukubhaka okuqhubekayo nakho kwenziwa. Imisebenzi yesithando ifana naleyo esetshenziselwa inqubo yokubhaka yezimo ze-electrode, kodwa
izitofu ngokuvamile zincane.
