Ibyuma byinshi bizakora firime ya okiside hejuru mugihe cyo kwitwara hamwe na ogisijeni mu kirere.Ariko kubwamahirwe, ibice byakozwe mubyuma bisanzwe bya karubone bizakomeza okiside, bituma ingese yaguka mugihe, amaherezo ikore umwobo.Kugirango twirinde iki kibazo, muri rusange dukoresha irangi cyangwa okiside irwanya okiside (nka zinc, nikel, na chromium) mugukoresha amashanyarazi hejuru yicyuma cya karubone.
Ubu bwoko bwo kurinda ni firime ya plastike gusa.Niba urwego rwo gukingira rwangiritse, ibyuma biri munsi bizatangira kubora.Aho bikenewe, hariho igisubizo, kandi gukoresha ibyuma bitagira umwanda birashobora gukemura neza iki kibazo.
Kurwanya kwangirika kwibyuma bitagira umwanda biterwa nibintu bya "chromium" mubigize, kuko chromium nikimwe mubice bigize ibyuma, kuburyo rero bwo kurinda ntabwo ari bumwe.Iyo ibirimo bya chromium bigeze ku 10.5%, birwanya ruswa yo mu kirere irwanya ibyuma byiyongera cyane, ariko iyo chromium iri hejuru, nubwo kurwanya ruswa bishobora gukomeza kunozwa, ingaruka ntizigaragara.
Impamvu nuko iyo chromium ikoreshwa mugukomeza ingano nziza yo kuvura ibyuma, ubwoko bwa oxyde yo hanze ihindurwamo okiside yo hejuru isa niyakozwe kumyuma ya chromium.Iyi oxyde ya chromium ikungahaye cyane irinda ubuso gukomeza okiside ikoresheje umwuka.Ubu bwoko bwa oxyde igabanutse cyane, kandi urumuri rusanzwe hanze yicyuma rushobora kuboneka binyuze muri rwo, bigatuma ibyuma bitagira umwanda bifite ubuso bwihariye bwibyuma.
Byongeye kandi, niba igice cyo hejuru cyangiritse, igice cyerekanwe hejuru kizisana ubwacyo hamwe nikirere cyikirere kandi cyongere gikore iyi "firime pasiporo" kugirango ikomeze kugira uruhare mukurinda.Kubwibyo, ibyuma byose bidafite umwanda bifite aho bihurira, ni ukuvuga ibirimo chromium iri hejuru ya 10.5%.
