Igice nyamukuru cyaUmuyoboro wa kareni zinc, byoroshye kubyitwaramo na ogisijeni mu kirere. Kuki ibara ryaUmuyoboro wa kareguhinduka umweru? Ibikurikira, reka tubisobanure birambuye.
Ibicuruzwa byashizwemo bigomba guhumeka kandi byumye. Zinc ni ibyuma bya amphoteric, bikora cyane. Kubwibyo, biroroshye kwangirika mubidukikije rusange. Bitewe no kwangirika gake, urwego rwa galvanised ruzagira kandi itandukaniro rinini ryamabara, bizagira ingaruka kumiterere yibicuruzwa.
Igihe cyose ishobora kwemeza guhumeka neza, niyo imvura yagwa, ariko mugihe ishobora gukama mugihe, ibicuruzwa bya galvanis ntabwo bizagira ingaruka nyinshi. Mu bubiko, ntigomba guhurizwa hamwe na aside, alkali, umunyu, sima nibindi bikoresho byangirikaimiyoboro ya kare. Imiyoboro ya karey'ubwoko butandukanye bugomba gutondekwa ukundi kugirango birinde urujijo no guhura kwangirika. Birashobora kubikwa mumasuka ahumeka neza; Ububiko bugomba gutoranywa ukurikije imiterere yimiterere. Mubisanzwe, ububiko rusange bufunze bwemejwe, ni ukuvuga ububiko bufite igisenge, uruzitiro, inzugi zifunze n'amadirishya hamwe nigikoresho cyo guhumeka; Ibisabwa mububiko: witondere guhumeka muminsi yizuba, gufunga muminsi yimvura kugirango wirinde ubushuhe, kandi uhore ubungabunga ibidukikije bikwiye.
