Bitewe nimikorere myiza yicyuma, irwanya ruswa kurusha ibindi byuma.Ibikoresho bikozwe mubyuma bidafite ingese nibyiza kandi biramba.Biroroshye koza nyuma yo kugwa kandi bakirwa nimiryango myinshi.
Ibyuma bitagira umwanda bikozwe mu cyuma cya chromium ivanze hamwe nicyuma cyerekana ibintu nka chromium, nikel na aluminium.Chromium irashobora gukora firime yuzuye ya passivation hejuru yicyuma kitagira umwanda kugirango irinde materique ibyuma kwangirika kandi igumane ituze ryicyuma.
Witondere ibibazo bikurikira mugihe ukoresheje ibyuma bidafite ingese:
1. Vinegere n'umunyu ntibigomba kubikwa igihe kirekire.
Umunyu na vinegere bizangiza passivation hejuru yicyuma kitagira umwanda, gushonga ibintu bya chromium, no kurekura ibyuma byubumara na kanseri.
2. Ntibikwiye gukoresha ibintu bikomeye bya alkaline mugusukura.
Ntukoreshe alkaline ikomeye cyangwa imiti ikomeye ya okiside nka soda yo guteka, ifu yo guhumeka, sodium hypochlorite kugirango woze ibyuma bidafite ingese.Kuberako ibyo bintu bikomeye bya electrolytite, bizakora amashanyarazi hamwe nicyuma kitagira umwanda.
3. Ntibikwiriye gutwikwa.
Kuberako ubushyuhe bwumuriro wibyuma bitagira umwanda biri munsi yibicuruzwa byibyuma nibicuruzwa bya aluminiyumu, kandi ubushyuhe bwumuriro bugenda buhoro, gutwika umwuka bizatera gusaza no kugwa kumurongo wa chrome washyizwe hejuru yibikoresho.
4. Ntugasige umupira wumupira cyangwa sandpaper.
Nyuma yo gukoresha ibyuma bidafite ingese mugihe runaka, ubuso buzatakaza urumuri kandi bugire urwego rwibintu bibi.Urashobora gushira umwenda woroshye muri poro yumwanda hanyuma ukahanagura witonze kugirango ugarure urumuri.Ntukayisigeho umupira cyangwa icyuma kugirango wirinde gushushanya hejuru yicyuma.
