Ibumba nubutaka bufatanye nuduce duto twumucanga, kandi bufite plastike nziza gusa mugihe amazi adashobora kuyanyuramo byoroshye.
Ibumba risanzwe rikorwa nikirere cyimyunyu ngugu ya silike hejuru yisi. Mubisanzwe, ikirere kiri mubihe. Ibice ni binini kandi ibihimbano byegereye ibuye ryumwimerere, ryitwa ibumba ryambere cyangwa ibumba ryibanze. Ibyingenzi byingenzi bigize ubu bwoko bwibumba ni silika na alumina, byera ibara ryamabara kandi bigahinduka, kandi nibikoresho nyamukuru byo gutegura ibumba rya farashi.
Ibumba muri rusange rikorwa nikirere cyimyunyu ngugu ya aluminiyose. Ariko diagenezi zimwe na zimwe zirashobora kubyara ibumba. Kugaragara kw'ibumba mugihe cyibikorwa birashobora gukoreshwa nkikimenyetso cyerekana iterambere rya diagenez.
Ibumba nigikoresho cyingenzi cyibanze. Igizwe na silicates zitandukanye zifite hydrata nubunini bwa alumina, oxyde ya alkali na oxyde ya alkaline yisi, kandi irimo umwanda nka quartz, feldspar, mika, sulfate, sulfide, na karubone.
Amabuye y'agaciro y'ibumba ni mato, akenshi mubunini bwa colloidal, muburyo bwa kristaline cyangwa butari kristaline, inyinshi muri zo zimeze nka flake, kandi nkeya zifite igituba cyangwa inkoni.
Amabuye y'agaciro y'ibumba ni plastiki nyuma yo kuvangwa n'amazi, irashobora guhindurwa munsi yumuvuduko muke kandi irashobora kuguma idahwitse igihe kirekire, kandi ifite ubuso bunini bwihariye. Ibice byashizwemo nabi, bityo bifite umubiri mwiza wa adsorption hamwe nibikorwa bya chimique yo hejuru, kandi birahujwe nibindi bikoresho. Ubushobozi bwo guhana.
Ukurikije imiterere nimikoreshereze, irashobora kugabanywamo ibumba ryibumba, ibumba ryangiritse, ibumba ryamatafari n ibumba rya sima. Ibumba rikomeye akenshi riba muburyo bwo guhagarika cyangwa ibisate. Mubisanzwe ntabwo yibizwa mumazi kandi ifite ubukana bwinshi. Nibikoresho nyamukuru byibicuruzwa bivunika. Ibumba rikomeye mu ibumba ryangiritse rikoreshwa mu gukora inganda zitanura itanura, kubumba amatafari no gucomeka amatafari yo gutanura ibyuma, amashyiga ashyushye, ningoma zicyuma. Mu nganda zubutaka, ibumba rikomeye n’ibumba rikomeye birashobora gukoreshwa nkibikoresho fatizo byo gukora ubukorikori bukoreshwa buri munsi, ubukorikori bwububiko n’ubukorikori bw’inganda.
