Mubihe bisanzwe, hazashyirwaho firime 10-20A ya okiside hejuru yicyuma kubera guhura na ogisijeni mu kirere.Mugihe cyo gukora firime karemano, ukurikije imiterere yumubiri yicyuma ubwacyo, imiterere yubuso hamwe nuburyo bwa okiside, zimwe muma firime ya oxyde yakozwe ni ntoya, amwe yuzuye kandi yuzuye, kandi amwe arekuye kandi atuzuye.Kenshi na kenshi, firime isanzwe ya oxyde yakozwe ntishobora kubuza neza icyuma kwangirika.
Hariho uburyo bwinshi bwo kuvura okiside yicyuma, harimo okiside yimiti ya alkaline, okiside idafite alkali, okiside yubushyuhe bwo hejuru hamwe na okiside ya electrochemic.Kugeza ubu, uburyo bwa okiside ya alkaline ikoreshwa cyane mu nganda.(Nuburyo bwa okiside ya aside)
Ibiranga firime ya oxyde: ibara ryiza, nta hydrogène yinjizwa, elastique, firime yoroheje (0.5-1.5um), nta ngaruka nini zigaragara ku bunini no ku bice by’ibice, kandi bigira n'ingaruka runaka mu gukuraho imihangayiko iterwa nyuma yubushyuhe kwivuza.
Kuvura umwijima ni uburyo bwo kuvura okiside yo hejuru.Ibice by'icyuma bishyirwa mubisubizo byibanze cyane bya alkali na okiside, gushyuha no okiside ku bushyuhe runaka, kuburyo hashyizweho urwego rwicyuma kimwe kandi cyinshi kandi kigahuzwa neza nicyuma fatizo.Inzira ya ferric oxyde yitwa blackening.Bitewe ningaruka zimpamvu zitandukanye zikora, ibara ryiyi firime nubururu-umukara, umukara, umutuku-umutuku, umutuku, nibindi.
Intego yo kuvura umwirabura ahanini ifite ingingo eshatu zikurikira:
1. Ingaruka zo kurwanya ingese hejuru yicyuma.
2. Ongera ubwiza nubwiza bwubuso bwicyuma.
3. Gushyushya mugihe cyijimye bifasha kugabanya imihangayiko mukazi.
Kuberako ubuvuzi bwirabura bufite ingaruka zavuzwe haruguru, igiciro ni gito, kandi ubuziranenge ni bwinshi, bukoreshwa cyane mugutunganya ibyuma no kwirinda ingese hagati yinzira.
