Pamwamba pretreatment pamaso zitsulo passivation mankhwala

Mkhalidwe wapamtunda ndi ukhondo wa gawo lapansi musanayambe chithandizo chachitsulo chosasunthika chidzakhudza kwambiri mtundu wa passivation wosanjikiza.Pamwamba pa gawo lapansili nthawi zambiri amaphimbidwa ndi oxide wosanjikiza, wosanjikiza wa adsorption, ndi zowononga zomatira monga mafuta ndi dzimbiri.Ngati izi sizingachotsedwe bwino, zidzakhudza mwachindunji mphamvu yogwirizanitsa pakati pa gawo la passivation ndi gawo lapansi, komanso kukula kwa crystalline, kachulukidwe, mtundu wa maonekedwe, ndi kusalala kwa gawo la passivation.Izi zingayambitse zolakwika monga kuwira, kupukuta, kapena kugwedezeka mu gawo la passivation, kulepheretsa mapangidwe osalala ndi owala osanjikiza ndi kumamatira bwino ku gawo lapansi.Kupeza malo oyera omwe adakonzedwa kale kudzera mu mankhwala ochiritsira ndikofunikira kuti apange magawo osiyanasiyana omangika mwamphamvu ku gawo lapansi.
