Ikariso y'icyuma

Kugeza ubu, karuvati isanzwe idafite isuku ku isoko ni ubwoko bwibicuruzwa bitagira umwanda bikoreshwa cyane cyane mu guhuza inganda no gutunganya. Kuberako ikozwe mubyuma bidafite ingese, ifite imbaraga zo kwangirika kwibyuma bitangiza imiti (aside, alkali, umunyu nibindi byangiza imiti).

Mugihe kimwe, ibicuruzwa bidafite ibyuma ntibigarukira kumiterere nubunini bwikintu. Imiterere yoroheje yububiko yoroshya ibintu bigoye bya gakondo, kandi imikorere myiza yo kwizirika itanga umutekano wikintu kiboshye. Icyuma kitagira umwanda gikozwe mu kurwanya ruswa hamwe n’ibikoresho birwanya ubushyuhe bwo hejuru kugira ngo ubwiza bw’ibidukikije bushobore gukingirwa. Birumvikana ko gukosorwa kwayo kwizewe cyane.

Ibyuma bitagira umuyonga hamwe nuduseke bikozwe mubyuma byo mu rwego rwo hejuru bidafite ibyuma, bikoreshwa cyane mubice bitandukanye n'imbaraga zazo. Gupakira amakarito akomeye kandi afatika, ibisanzwe byapakirwa bya pulasitike byoroshye, agasanduku gashya karimo ibintu byoroshye kandi bishushanyije neza, bishobora kwerekana amasano asigaye, ashobora gukururwa nkuko bikenewe. Uruzitiro r rwuzuye rwumukandara uhuza umutekano kandi byoroshye gushiraho. Irashobora kandi guhambirwa mubice bibiri kugirango yongere ubushobozi bwimitwaro. Birakwiriye cyane kwangirika kwangirika, ubushuhe, amazi yinyanja nibindi bidukikije. Irashobora gutunganya ibisobanuro byose
