Hot kuviika kanasonkhezereka lalikulu chubu ndi zitsulo chitoliro mankhwala wadutsa processing wapadera. Kapangidwe kake kumaphatikizapo kumiza chubu lalikulu mumadzi osungunuka a zinki, zomwe zimapangitsa kuti pakhale kusintha kwamankhwala pakati pa nthaka ndi chitsulo pamwamba, potero kupanga wosanjikiza wandiweyani wa zinki pamwamba pa chitoliro chachitsulo. Zotsatirazi ndikuwunika mwatsatanetsatane mapaipi otentha a dip galvanized square rectangular:
Kuchiza: Mapaipi achitsulo amayenera kutenthedwa kuti achotse pamwamba pa iron oxide ndi zonyansa zina. Kenako, kuyeretsa kwina kumachitika ndikusakaniza ammonium chloride ndi zinc chloride amadzimadzi njira kuonetsetsa kuti pamwamba pa chitoliro zitsulo ndi woyera ndi wopanda dothi.
Dip plating yotentha: Chitoliro chachitsulo chomwe chidakonzedwa kale chimatumizidwa mu thanki yotenthetsera ya dip, yomwe imakhala ndi zinki yosungunuka. Zilowerereni chitoliro chachitsulo mu njira ya zinki kwa kanthawi kuti zinki igwire bwino ntchito pamwamba pa chitsulocho, ndikupanga wosanjikiza wachitsulo chachitsulo.
Kuziziritsa ndi kuchiritsa pambuyo: Chitoliro chachitsulo cha malata chimachotsedwa muzitsulo za zinki ndikuzizidwa. Masitepe ena pambuyo pokonza monga kuyeretsa, passivation, etc. akhoza kuchitidwa pakufunika kuti apititse patsogolo kukana kwa dzimbiri ndi khalidwe lapamwamba la chitoliro chachitsulo.
