Ubushinwa Bwiza Ubukonje Bwiza Buzungurutse Bishyushye Buke bwa Carbone Icyuma
Ubwoko bw'ibyuma bisanzwe bigabanyijemo ubwoko butatu: isahani yuzuye (hejuru ya 6mm), isahani yo hagati (3-6mm) hamwe n'amasahani mato (munsi ya 3mm) ukurikije ubunini bwayo.Kubyerekeranye no gukora amasahani, ibyuma bya karubone nkeya birashobora kugabanywamo ubwoko bubiri: gukonjesha no gushyuha.Kuzunguruka bishyushye byonyine birashobora kubyara ibyuma bya karuboni nkeya ya 1,2mm hamwe nicyuma kitagira umwanda kingana na 2mm.Isahani yoroheje irashobora gukorwa no gukonjesha, gukonjesha no gutondeka.
Ibyuma bya karubone bikoreshwa cyane mumashini n'ibikoresho byinshi byumwuga hamwe nibice binini byubatswe mubikorwa byinganda.Kurugero, mubikorwa byubwubatsi, ingufu nubucukuzi bwamabuye y'agaciro, ibicuruzwa byinshi bikoresha ibyuma bifite uburebure bwa mm 6-20.Bimwe muribi byuma ni isahani iringaniye idafite umwobo, kandi ibyinshi muri byo ni amasahani afite ububobere bwa 30%.
