Chitsulo chosapanga dzimbiri chitoliro ndi mtundu wa dzenje yaitali cylindrical zitsulo.Kukula kwake kumagwiritsidwa ntchito ngati payipi potumiza madzimadzi.Amagwiritsidwa ntchito kwambiri m'mapaipi otumizira mafakitale monga mafuta, makampani opanga mankhwala, chithandizo chamankhwala, chakudya, mafakitale opepuka, zida zamakina ndi zida zamakina.Mapaipi achitsulo osapanga dzimbiri amapangidwa ndi ma billet achitsulo a asidi ndi magiredi osamva kutentha kudzera pakutenthetsa, kubowola, kukula, kugudubuza ndi kudula.Ndipotu, palibe mankhwala omwe angatetezedwe ku dzimbiri pokhapokha ngati atakhala ovuta kwambiri.Ngati mbale yathu ya chitsulo chosapanga dzimbiri yachita dzimbiri, ikhoza kusokoneza kagwiritsidwe ntchito kake.Chifukwa chake, tikuyenerabe kuchitapo kanthu kuti tipewe izi.Tsopano tiyeni timvetse kaye zinthu zomwe zimayambitsa dzimbiri za mbale zazitsulo zosapanga dzimbiri?
(1) Electrochemical corrosion:The zikande chifukwa kukhudzana pakati zosapanga dzimbiri zitsulo mbale ndi carbon zitsulo mbali, ndiyeno kupanga galvanic selo ndi sing'anga zikuwononga, amene adzabala electrochemical dzimbiri.Ngati pickling passivation zotsatira si zabwino, passivation filimu pamwamba pa mbale adzakhalanso osagwirizana kapena woonda kwambiri, amenenso n'zosavuta kutulutsa electrochemical dzimbiri, slag kudula, kuwaza ndi zina dzimbiri sachedwa zinthu Ufumuyo mbale, ndi kenako pangani galvanic cell ndi zowononga sing'anga, zomwe zimapangitsa kuti electrochemical corrosion.Pickling ndi passivation kuyeretsa si woyera, chifukwa mankhwala dzimbiri mankhwala pakati otsala pickling ndi passivation zotsalira ndi mbale, ndiyeno electrochemical dzimbiri ndi mbale.
(2) Pazifukwa zina, dothi lambiri lamafuta, fumbi, asidi, alkali, mchere, ndi zina zambiri zomwe zimayikidwa pamwamba pazitsulo zosapanga dzimbiri zidzasinthidwa kukhala zowononga zowonongeka, zomwe zidzakhudzidwa ndi mankhwala ndi zigawo zina mu mbale, zomwe zimapangitsa kuti pakhale dzimbiri ndi dzimbiri.Kuyeretsa, pickling ndi passivation si oyera mokwanira, chifukwa cha kusungidwa kwa madzi otsalira, omwe amawononga mbale.Pamwamba pa mbaleyo amakankhidwa, zomwe zimatsogolera ku chiwonongeko cha filimu yowonongeka, kotero kuti mphamvu yotetezera mbale imachepetsedwa, ndipo n'zosavuta kuchitapo kanthu ndi mankhwala.
