Kubyerekeranye nuburyo umuyoboro wibyuma washyutswe, inzira yo gushyushya ibishishwa bivamo guhuza metallurgji hagati ya zinc nicyuma hamwe nuruhererekane rwibyuma-zinc bitandukanye. Ubusanzwe umurongo ushyushye-wohanagura umurongo ukora kuburyo bukurikira:
1. Icyuma gisukurwa hifashishijwe igisubizo cya caustic. Ibi bikuraho amavuta / amavuta, umwanda, hamwe n irangi.
2. Umuti wo gusukura caustic wogejwe.
3. Icyuma gitoragurwa mumuti wa acide kugirango ukureho urusyo.
4. Umuti wo gutoragura wogejwe.
5. flux, akenshi zinc ammonium chloride ikoreshwa mubyuma kugirango ibuze okiside yubuso bwera iyo ihuye numwuka. Amazi yemerewe gukama kumyuma hamwe nugufasha mugihe cyamazi ya zinc yatose no kwizirika kumyuma.
6. Ibyuma byinjizwa mu bwogero bwa zinc zashongeshejwe hanyuma bikabikwa aho kugeza ubushyuhe bwibyuma buringaniye nubwogero.
7. Icyuma gikonjeshwa mu kigega cyo kuzimya kugira ngo kigabanye ubushyuhe bwacyo kandi kibuze ingaruka zitifuzwa ziterwa n’ikirere gishya.
Muburyo bwa tekiniki, galvanisiyasi ni inzira yo gutwikira ibyuma nicyuma hamwe nigice cya zinc wibiza icyuma mu bwogero bwa zinc yashongeshejwe ku bushyuhe bwa 840 ° F (449 ° C). Iyo ihuye nikirere, zinc yera (Zn) ikorana na ogisijeni (O2) ikora okiside ya zinc (ZnO), ikongera igakora na dioxyde de carbone (CO2) ikora karubone ya zinc (ZnCO3), ubusanzwe imvi zijimye, zikomeye cyane. ibikoresho birinda ibyuma munsi yandi kwangirika mubihe byinshi. Mubisanzwe, umuyoboro ushyushye wa galvaniside ufite igiciro cyicyuma cyinshi ugereranije nubundi bwoko busanzwe bwimiyoboro ikoreshwa kubera igiciro cyinshi cyo gukora ku isoko.
Kubikorwa bifatika, kimwe nubundi buryo bwo kwirinda ruswa, galvanizing irinda cyane cyane ibyuma bikora nkinzitizi hagati yicyuma nikirere. Nyamara, zinc nicyuma cya electronegatifike ugereranije nicyuma. Nibintu byihariye biranga galvanizing. By'umwihariko, iyo igipfundikizo cyangiritse cyangiritse kandi ibicuruzwa byuma bikagerwaho nikirere, zinc irashobora gukomeza kurinda ibyuma binyuze muri ruswa. Ikigeretse kuri ibyo, niba iyi coating ibaye yashushanijwe cyangwa igashishwa, defence ya kabiri ya zinc irahamagarirwa kurinda ibyuma nibikorwa bya galvanic. Mu rusyo, ubunini bwa zinc bugenzurwa nigihe buri gice cyinjizwa mu bwogero bwa zinc yashongeshejwe kimwe n’umuvuduko ukuramo. Ijambo "kwibiza kabiri" bivuga ibice binini cyane ku buryo bidashobora guhurira mu isafuriya ya galvanizing kandi bigomba kwibizwa ku mpera imwe icyarimwe. Ntabwo bivuga kubyibushye byiyongera. Nkumushinga wibyuma wabigize umwuga mubushinwa, twiyemeje gukora ubwoko butandukanye bwibyuma byimishinga yawe. Kubindi bisobanuro, urashobora kutwandikira igihe icyo aricyo cyose.
