Thekuphandi gawo lofunikira la zida zambiri zamakina.Monga chowonjezera chachitsulo, ngati sichigwiritsidwa ntchito kwa nthawi yaitali kapena sichisamalidwa bwino, zimakhala zosavuta kuti dzimbiri.Ngati corrodmphetesichimachiritsidwa mu nthawi, ntchito yake idzakhudzidwa.Lero tikuwonetsa njira zingapo zochotsera dzimbiri kumphete

Kuti malo ozungulira azikhala oyera, sankhani chosungunulira choyenera choyeretsera molingana ndi momwe zinthu zilili pamwamba pa chinthu chotsutsana ndi dzimbiri, kuti musawononge dzimbiri.Kuyeretsa pamwamba kumatha kutengera njira yoyeretsera mankhwala ndi makina oyeretsera.Pamwamba pawouma, chitani ntchito yabwino poyang'anira kutentha ndikudikirira mpaka malo ambiri auma musanapukute ndi gauze.Mukamagwiritsa ntchito mafuta oletsa dzimbiri, njira zosiyanasiyana ziyenera kutsatiridwa kuti zigwiritse ntchito njira zosiyanasiyana zonyamula katundu.Zinyalala zazing'ono zimatha kumizidwa mwachindunji mumafuta odana ndi dzimbiri.Ngati mukukumana ndi mawonekedwe apadera, mukhoza kusankha njira yojambula, kotero kuti sizovuta kupanga mafuta ochuluka.Pali zinthu zambiri zomwe zimayambitsa dzimbiri zachitsulo.Kapangidwe kake kachitsulo kamene kamatha kuyambitsanso dzimbiri kapena kutentha ndi chinyezi cha chilengedwe chomwe chinthucho chilipo kungayambitsenso dzimbiri.

Zinanjirandi kuthirakuphamutothanki yolimbana ndi dzimbiri: kumizakuphamu njira yamadzimadzi ya 5% sodium nitrite ndi 0.6% sodium carbonate.Mwanjira iyi, anti-dzimbiri zotsatira zakupha ndiwothandiza kwambiri.

Komanso, mukhoza kufunsa Mlengi kuchita galvanizing kapena phosphating mankhwala pamene kulamulamphete, zomwe zingateteze bwino dzimbiri.
