galvanised fer urunigi rwiza kumushinga wawe
Urunigi rw'icyuma rushyizwemo ni reaction y'icyuma gishongeshejwe hamwe na materique y'icyuma kugirango habeho urwego ruvanze, kugirango matrike na coating bihuze.Urunigi rw'icyuma rwa Galvanised ni urunigi rwa mbere rwo gutoragura, kugirango ukureho okiside ya fer hejuru yurunigi, nyuma yo gutoragura, ukoresheje amonium chloride ya amonium cyangwa zinc chloride yumuti wamazi cyangwa chloride ya amonium na zinc chloride ivanze nigisubizo cyamazi yo kwisukura, hanyuma mu kigega gishyushye.Urunigi rwicyuma rufite ibyiza byo gutwikira kimwe, gukomera hamwe no kuramba kuramba.
Urunigi rw'icyuma rushyushye rushyushye cyane rushingiye ku cyuma gisudira (ni ukuvuga, zinc ishonga mu nkono ya zinc, hanyuma urunigi rwinjizwa muri zinc y'amazi mu gihe runaka kugirango rusohoke, hanyuma gukonjesha no gukama ).
Urukuta rw'imbere n'inyuma rw'umunyururu rufite urwego rwa zinc rwometse icyarimwe.Urunigi rw'icyuma rusanzwe rukoreshwa mugutanga umuvuduko muke (ni ukuvuga amazi, gaze y'amazi).
Imiterere yumubiri wumunyururu usanzwe hamwe numunyururu wa galvanised ni kimwe, ariko kubera ko igifuniko cyo hejuru gitandukanye, kurwanya kwangirika kwabo ntabwo ari kimwe.
Imwe, urunigi rusanzwe: chromium nicyuma cyamabara ya feza, irahagaze neza mukirere, ndetse no muri alkali, aside nitric, sulfide, igisubizo cya karubone nacyo gishobora gukomeza guhagarara neza.Chrome ifite imiterere ikomeye, irwanya kwambara, kandi irashobora kugumana igihe cyayo igihe kirekire.Ingaruka zo gufata chromium ni uko itarinda icyuma fatizo ingese.Irabanzirizwa rero no gutwikira umuringa cyangwa umuringa-amabati uhuza neza nicyuma fatizo.Muri rusange, urunigi rushyizweho na chrome rufite ibiranga igiciro gito cyane, imodoka zo mu rwego rwo hejuru zo mu rugo, imodoka zigendanwa ahanini hamwe nazo, muri rusange ntabwo zisabwa gukoresha.
Babiri, urunigi rwinshi: urunigi rwerekana ibara ryicyatsi kibisi.Nibisubizo bya passivation ya cinc coating ikurikirwa no guhumeka.Ipitingi ya zinc ihinduka bike mumuyaga wumye.Mu kirere cyuzuye, mu mazi arimo karuboni ya dioxyde na ogisijeni, ubuso bwayo bukora firime yoroheje ya karubone nyamukuru ya zinc.Iyi firime ifite ingaruka zo kubuza ruswa.Irashobora gukumira kwangirika kwicyuma.Turabona ko iminyururu imwe ihindagurika ihinduka kuva cyera ikahinduka umukara vuba nyuma yo kuyikoresha, ariko ntamahinduka akomeye nyuma yibi, impamvu nuko.
Ugereranije n'iminyururu isanzwe, iminyururu ya galvanis mu gukora no kuyitunganya nyuma yo kuvurwa bidasanzwe, mugukoresha ibintu byiza cyane, kuburyo haba mubuzima bwibicuruzwa cyangwa gukoresha nyabyo byavuzwe haruguru bifite impamyabumenyi zitandukanye zo gutera imbere.Inzira ya Galvanised iroroshye, igiciro ni gito, kubwoko busanzwe, igare riremereye rikoreshwa hamwe naryo.
