Isahani yicyuma ni ukubuza ubuso bw'isahani y'icyuma yo gukongiba no kwiyongera ubuzima bwa serivisi, kandi ubuso bw'isahani y'icyuma ikongerera igice cy'icyuma zinc.
Ukurikije uburyo bwo gukora no gutunganya, bushobora kugabanywamo ibyiciro bikurikira:
1 Ashyushye-Dip Gallvanional urupapuro. Urupapuro rwicyuma rwibizwa mu bwogero bwa binc, kandi urupapuro rwa zinc rufite ishingiro. Kugeza ubu, hakorwa ahanini nuburyo buhoraho, ni ukuvuga isahani yicyuma yiruka ikorwa no guhindagurira amasahani yicyuma cyicyuma mu kigega cyo gutakaza aho zinc yashonze;
2 ALLY Urupapuro rwibyuma. Ubu bwoko bw'isahani y'icyuma nabwo bukorwa nuburyo bushyushye bushyushye, ariko nyuma yacyo buva kuri tank, bikaba bigera kuri 500 ℃ Ako kanya kugirango akore firime ya Acloy ya Zinc na Icyuma. Uru rupapuro rwamaguru rufite amarangi meza kandi asukura;
Urupapuro 3 rwa electro-govani. Urupapuro rwibyuma gakondo rwakozwe nuburyo bwa electroplating bufite akazi keza. Ariko, ipfundo rinanutse, kandi irwanya ruswa ntabwo ari nziza nkiz'urupapuro rushyushye-kwibiza;
4 Impande zose kandi zitandukanijwe kabiri steel. Urupapuro rumwe rwibyuma, ni ukuvuga ibicuruzwa byiruka kuruhande rumwe gusa. Mu gusudira, gushushanya, guhirika ingendo, gutunganya, nibindi, bifite akamaro keza kuruta urupapuro rwinshi. Kugirango dutsinde ibibi ko uruhande rumwe rutagizwe na zinc, hari urundi rupapuro rwamaguru rwapakiwe hamwe na zinc kurundi ruhande, ni ukuvuga, urupapuro rutandukanijwe kabiri;
5 Alloy, igikomangoma cya gari ya gallpose. Ikozwe muri zinc hamwe nizindi shyanga nka aluminium, kuyobora, zinc, nibindi kugirango bishobore kuri alloys cyangwa ibyapa byanditseho amasahani yicyuma. Ubu bwoko bw'icyuma ntabwo bufite imikorere myiza yo kurwanya ingese, ariko nanone ifite imikorere myiza;
Usibye ubwoko butanu bwavuzwe haruguru, hari kandi amabati yicyuma, yacapwe kandi ashushanyije amabati ya gall ya gaje, na PVC amabati ashizeho impapuro zipatanye. Ariko ikoreshwa cyane iracyafite urupapuro rushyushye.
Umusaruro nyamukuru n'ibihugu bitumizwa mu mahanga:
1 Ibihingwa nyamukuru byo mu gihugu: Wuhan Iron na Icyuma, Ansan Icyuma na Baoning, Icyuma, Shoan
2 Abakora abanyamahanga nyamukuru ni Ubuyapani, Ubudage, Uburusiya, Ubufaransa, Koreya y'Epfo, nibindi
