Ni ikihe kigereranyo cyo kuvanga bentonite mu gucukura ibyondo?

Ikigereranyo cyo kuvanga bentonite mu gucukura ibyondo kirashobora gutandukana bitewe nibisabwa byihariye mubikorwa byo gucukura n'ubwoko bw'ibyondo byo gucukura bikoreshwa. Bentonite ni ikintu cyingenzi mu gucukura ibyondo, kandi intego yacyo nyamukuru ni ukuzamura ububobere n’amavuta y’ibyondo. Ikigereranyo cyo kuvanga neza ningirakamaro kugirango ugere kubikorwa byiza byo gucukura.

Mubisanzwe, bentonite ivangwa namazi kugirango ibe ibicucu, kandi igipimo cyo kuvanga kigaragazwa nkubunini bwa bentonite (kuburemere) bwongewe kumazi runaka. Ibyifuzo biranga ibyondo byo gucukura, nk'ubukonje, imbaraga za gel, hamwe no kugenzura kuyungurura, bigira ingaruka kumahitamo yo kuvanga.

Ibintu byinshi bigira uruhare mukumenya igipimo cyo kuvanga, harimo ubwoko bwa bentonite ikoreshwa (sodium bentonite cyangwa calcium bentonite), imiterere yo gucukura, nibisabwa byihariye mubikorwa byo gucukura. Izi ngingo zigomba gufatwa kugirango zihuze icyondo cyo gucukura n’imiterere ya geologiya iranga gucukurwa.

Sodium bentonite ni ubwoko bwa bentonite ikunze gukoreshwa mu gucukura ibyondo. Ikigereranyo gisanzwe cyo kuvanga ibumba rya sodium bentonite ni ibiro 20 kugeza kuri 35 byibumba bya bentonite kuri litiro 100 zamazi. Ariko, iri gereranya rishobora guhinduka hashingiwe kubisabwa byihariye byo gucukura.

Kalisiyumu bentonite, kurundi ruhande, irashobora gusaba igipimo gitandukanye cyo kuvanga ugereranije na sodium bentonite. Guhitamo hagati ya sodium bentonite na calcium bentonite biterwa nibintu nkimiterere yamazi yifuzwa, umunyu wamazi yo gucukura, nibiranga geologiya yibiranga.

Usibye ibipimo fatizo bivanze, gucukura ibyondo birashobora kuba birimo izindi nyongeramusaruro kugirango zongere imikorere. Izi nyongeramusaruro zirashobora kuba zirimo polymers, viscosifiers, imiti igenzura amazi, hamwe nuburemere. Imikoranire hagati ya bentonite ninyongeramusaruro isuzumwa neza kugirango igere kumiterere yifuzwa ya rheologiya no gucukura ibyondo biranga.

Ni ngombwa ko abahanga mu gucukura bakora ibizamini bya laboratoire hamwe n’ibigeragezo byo mu rwego rwo guhuza ibipimo bivangwa n’ibikorwa byihariye byo gucukura. Icyari kigamijwe kwari ugukora icyondo cyo gucukura cyajyana neza gutema imyanda hejuru, bigatanga umutekano ku mwobo, kandi byujuje ibisabwa n’ibidukikije n’amabwiriza y’ahantu hacukurwa.

Ikigereranyo cyo kuvanga bentonite mugucukura ibyondo nikintu gikomeye gitandukana ukurikije ibintu nkubwoko bwa bentonite, imiterere yo gucukura hamwe nibisabwa byondo. Abakora umwuga wo gucukura basuzumye bitonze ibyo bintu kugirango bamenye igipimo cyiza cyo kuvanga kubikorwa byihariye byo gucukura, bareba neza ibisubizo byiza.
