Mu kwubaka amazi n’imiyoboro y’amazi, imiyoboro yo kurwanya umuriro-, n’ibifadika vy’imibumbe y’ivyuma, imiyoboro y’ivyuma ikozwe mu cuma ni yo ikoreshwa cane. Ariko rero, ingorane nk’ugusenyuka kwa zinc, gusenyuka, gusenyuka kw’icuma c’ishimikiro, n’ugusenyuka kw’ivyuma vya zinc vyo mu karere birakunda gushika. Ivyo bintu ntibigira ico bikoze ku kuntu bisa gusa, ariko kandi biratuma iyo miyoboro y’icuma yihuta gusenyuka, bigatuma imara igihe gito. None ni izihe mpamvu nyamukuru zituma zinc ipfuka ku miyoboro y’icuma ikozwe mu cuma? Ni gute bikwiye gufatwa ku-site mu gihe c'ivyihutirwa? Kandi vyoshobora gute gukingirwa mu gihe c’ubwubatsi busanzwe?
Ubwa mbere, nushire ahabona muri make ibintu bibiri nyamukuru:
Gutakaza zinc bike: gusenyuka kw’aho hantu canke gusesagura ahantu hatoyi-, igice ca zinc kiratandukana gusa ku ruhande, kandi igice c’umuyoboro w’icuma kiguma ari co nyene.
Gutakaza cane zinc: ahantu hanini-gushirwa ahabona kw’icuma, igice ca zinc kirasenyuka mu bipande vyose, kijana n’umugese, mbere n’ibinogo vyarabonetse.
Hanyuma ugereranye kandi usesengure ivyo bintu bibiri:
Gutakaza zinc gatoyi: Ivyo bishobora guterwa n’ibipfunsi vy’ugutwara, ugusudira kw’ubushuhe bwinshi-, ugushikana kw’aho hantu, ugusenyuka gutoyi, n’izindi mpamvu; ni ikintu coroshe gukoresha kandi gishobora gusanurwa aho hantu nyene; inyuma yo gusanura, mu bisanzwe igikorwa c’intango kirasubiraho.
Gutakaza cane zinc: Ivyo bishobora guterwa n’utunenge turi mu nzira yo gutera ivyuma, ugusenyuka kw’aside canke alkali ikomeye, ubukonje bw’igihe kirekire-, canke ukwononekara gukomeye kw’ugusudira; biragoye cane gukoresha, bisaba gukuraho umugese no kwongerako zinc, kandi iyo bikomeye cane, vyoshobora gukenerwa gusubirizwa amatiyo; iyo imaze gusanurwa, ubuzima buzogabanywa kandi birakenewe ko umuntu ayibungabunga ubudasiba.
Ubwa nyuma, nusuzume ukurikije ivyabaye mu gukoresha:
Ivyabaye 1: Gusesagura zinc mu gihe gito mu binogo bitobito biri ku kibanza c’ubwubatsi → Gutera irangi ry’ivyuma ry’agaciro mu bibanza bitobito, ryihuta kwubaka, ridahenda cane, kandi ntirigira ico rihinduye ku rutonde.
Ivyiyumviro vya 2: Gusenyuka kwa zinc ahantu hanini -ku bihimba vy’ugusudira → Utegerezwa kubanza gusya no gukuraho umugese, hanyuma ugatera irangi ry’umugese -muri rusangi, ahandi ho umugese urashobora cane gusenyuka no gusohoka mu bihimba vy’ugusudira.
Ivyerekeye 3: Gukuraho zinc mu bibanza vy’inyuma vy’igihe kirekire-bifise ubukonje → Guhitamwo gukoresha imiyoboro y’ivyuma vy’agaciro, no kwongerako igipfukisho co hejuru kugira ngo ukingire inyuma y’ubwubatsi kugira ngo ugabanye amahera yo kwitaho mu nyuma.
Mu ncamake, ingingo ngenderwako nyamukuru yo guhangana n’ugutakaza zinc mu miyoboro y’icuma ikozwe mu cuma ni: ku gutakaza zinc gutoyi, gusanura ahantu ku gihe; ku bijanye n’ugutakaza zinc cane, ukureho umugese wose hanyuma wongere ukoreshe ivyuma. Kugira ngo umuntu akingire ingorane mu buryo bw’ishimikiro, ikintu nyamukuru ni ukugenzura ibintu bitatu: ica mbere, uburyo bwo gutera ivyuma igihe umuntu agura imiyoboro; ica kabiri, ukwikingira mu gihe co gutwara no gushiramwo; ica gatatu, ni ugusanura ku gihe inyuma yo gusudira. Mu gutwara neza igikorwa cose ni ho gusa ubuzima bw’imiyoboro y’icuma gikozwe mu cuma bushobora kwaguka cane.
