Isahani isize amabara nayo yitwa organic icyuma gisizecyangwa icyuma cyabitswe mbere. Nuburyo bukomeza bwo gukora ibishishwa, ibyuma byamabara birashobora kugabanwa muburyo bubiri: amashanyarazi-ashyushye hamwe na hot-dip galvanised.
Muri icyo gihe, electro-galvanizing nuburyo bwo gukora irangi ryometseho zahabu- "layer zinc metal cyangwa zinc alloy" binyuze mumashanyarazi.
Ashyushye cyane, izwi kandi nka hot-dip galvanizing, ni ugushira ibyuma bikenera kubungabungwa mubyuma bya zinc byashongeshejwe kugirango bigaragare neza. Ugereranije na electroplating, icyuma gishyushye-gipfundikanya ni kinini; munsi y'ibidukikije bimwe, bifite ubuzima burebure.
Kwangirika kwa hot-dip ya galvanisiye hejuru yicyuma ihwanye na zinc nziza. Kwangirika kwa zinc mu kirere bisa nuburyo bwo kwangirika kwibyuma mubihe byikirere. Imiti ya okiside ya chimique ibaho, amashanyarazi yangirika bibaho hejuru ya zinc, hamwe na firime ya firime iba. Mu kirere kidafite aho kibogamiye cyangwa acide, ibicuruzwa byangirika byakozwe nicyuma cya galvaniside ni ibintu bitangirika (hydroxide ya zinc, okiside ya zinc, na karubone ya zinc). Ibicuruzwa bizatandukanywa no kubitsa no gukora igicucu cyiza.
Muri rusange irashobora kugera ku bunini bwa 8 mm ”. Ubu bwoko bwa firime ifite umubyimba runaka, ariko ntishobora gushonga mumazi gusa, kandi ifatanye neza. Kubwibyo, irashobora gukina inzitizi hagati yikirere nurupapuro. Irinde kwangirika. Igice cya galvanise cyangiritse mugihe cyo kubungabunga, kandi igice cyicyuma gihura nikirere.
Muri iki gihe, zinc na fer bigize bateri ntoya. Ubushobozi bwa zinc buri hasi cyane kurenza icyuma. Nka anode, zinc ifite uburyo bwihariye bwo kubungabunga anode kumurongo wibyuma kugirango wirinde kwangirika kwicyuma.
Ikibaho gisize amabara ni ubwoko bwamazi asukuye, ashyirwa hejuru yicyuma gisukuye cyangwa gukubitwa. Nyuma yo gushyushya no gukiza, hashobora kuboneka firime irangi ifite uburebure bumwe.
