Isahani yicyuma ni ukurinda hejuru yicyuma cyangirika kandi ikongerera igihe cyakazi, kandi hejuru yicyapa cyometseho icyuma cya zinc.
Ukurikije uburyo bwo gukora no gutunganya, birashobora kugabanywamo ibyiciro bikurikira:
1 Urupapuro rushyushye. Urupapuro rwamabati rwinjijwe mu bwogero bwa zinc zashongeshejwe, kandi urupapuro rwa zinc rwometse ku buso bwarwo. Kugeza ubu, ikorwa cyane cyane nuburyo bukomeza bwo gusya, ni ukuvuga isahani yicyuma ikorwa no guhora wibiza ibyuma byiziritse mu kigega aho zinc yashonga;
2 Kuvanga urupapuro rwicyuma. Ubu bwoko bwicyuma nabwo bukozwe muburyo bushyushye, ariko nyuma yo kuva muri tank, burashyuha kugeza kuri 500 ℃ ako kanya kugirango bukore firime ivanze ya zinc nicyuma. Uru rupapuro rwometseho rufite irangi ryiza hamwe no gusudira;
3 Urupapuro rw'amashanyarazi. Urupapuro rwicyuma rwakozwe nuburyo bwa electroplating rufite imikorere myiza. Nyamara, igifuniko ni gito, kandi kurwanya ruswa ntabwo ari byiza nkibya shitingi ishyushye;
4 Uruhande rumwe kandi rufite impande ebyiri zitandukanye ibyuma bya galvanis. Urupapuro rumwe rukomeye rwerekana ibyuma, ni ukuvuga ibicuruzwa bisunikwa kuruhande rumwe gusa. Mu gusudira, gushushanya, kuvura anti-rust, gutunganya, nibindi, bifite imiterere ihindagurika kuruta impapuro ebyiri. Kugirango tuneshe imbogamizi uruhande rumwe rudashyizwe hamwe na zinc, hari urundi rupapuro rwometseho uruzitiro rwometseho urwego ruto rwa zinc kurundi ruhande, ni ukuvuga impande zombi zitandukanye;
5 Amavuta avanze, akomatanya urupapuro rwicyuma. Ikozwe muri zinc nibindi byuma nka aluminium, gurş, zinc, nibindi kugirango ikore ibishishwa cyangwa se ibyuma bisobekeranye. Ubwoko bw'icyuma ntabwo bufite imikorere myiza yo kurwanya ingese gusa, ahubwo bufite imikorere myiza yo gutwikira;
Usibye ubwoko butanu bwavuzwe haruguru, hari n'amabati yamabara yamabara, yacapishijwe kandi ashushanyijeho amabati, hamwe na PVC yamashanyarazi yamashanyarazi. Ariko cyane cyane ikoreshwa iracyari hot-dip urupapuro.
Ibicuruzwa nyamukuru bitanga umusaruro n’ibihugu bitanga umusaruro:
1 Ibihingwa ngandurarugo bikomoka mu gihugu: Wuhan Iron and Steel, Anshan Iron and Steel, Baosteel Huangshi, MCC Hengtong, Shougang, Panzhihua Iron and Steel, Handan Iron and Steel, Maanshan Iron and Steel, Fujian Kaijing, nibindi.;
2 Abatunganya ibicuruzwa nyamukuru ni Ubuyapani, Ubudage, Uburusiya, Ubufaransa, Koreya yepfo, nibindi
