Umuyoboro w'icyumaisanzwe ikoreshwa ahantu hose mubuzima bwabantu, kubaka inganda nizindi nganda, murizoinsinga z'icyumani Byamamaye cyane;Icyitegererezo cyingirakamaro gifite ibyiza byo gukoresha mugari, hejuru yubuso, nta guturika gukabije hamwe ningese, kurwanya ruswa neza, gukomera no gukomera kuruta ibyuma bisanzwe, kandi birashobora kugororwa inshuro nyinshi.

Umuyoboro w'icyumaikorwa mugushushanya 45 #, 65 #, 70 # nibindi byuma byiza byo mu rwego rwo hejuru byubaka ibyuma, hanyuma bigahinduka (amashanyarazi ya elegitoronike cyangwa ashyushye).Imiterere yacyo ni kimwe nicyuma kigororotse kandi cyoroshye.Irashobora gukoreshwa nkibishimangira gushimangirwa, ariko igomba gushyirwaho byibuze 200 ~ 300g zinc kuri metero kare.Bikunze gukoreshwa nkumugozi wicyuma kibangikanye nicyuma cyagumyeho ikiraro (hiyongereyeho, umugozi woroshye wa kabili nawo ukoreshwa nkuburinzi bwo hanze).

Intego:

Ikoreshwa cyane cyane mu gutera pariki, imirima, gupakira ipamba,insinga z'icyuma zo kubaka, isoko naumugozi w'icyumainganda.Irakwiranye nubwubatsi bufite ibidukikije bikaze nkibikoresho byibyuma nibigega byumwanda byikiraro cyagumye.

Kubwibyo, kubera ubwiza buhebuje kandi bugari bukoreshwa, irashobora kwinjizwa neza mubice byose byubuzima bwabantu, bityo bizamenyekana cyane kuruta insinga zicyuma zisanzwe.
