Bentonite ni amabuye y'agaciro atari ubutare ahanini agizwe na montmorillonite.Imiterere ya montmorillonite ni ubwoko bwa 2: 1 bwa kirisiti igizwe na silika tetrahedra ebyiri ya silika yashizwemo na layer ya aluminium oxyde octahedra.Bitewe nuburyo butandukanye bwakozwe na selile ya montmorillonite, hari cations zimwe na zimwe, nka Cu, Mg, Na, K, nibindi, kandi imikoranire yabo na selile ya montmorillonite ntigihungabana cyane, byoroshye guhanahana nizindi cations, bafite rero imitekerereze myiza ya ion.Mu mahanga, yakoreshejwe mu mashami arenga 100 mu bice 24 by’inganda n’ubuhinzi, hamwe n’ibicuruzwa birenga 300, bityo abantu bakabyita “ubutaka rusange”.

Bentonite izwi kandi nka bentonite, bentonite, cyangwa bentonite.Ubushinwa bufite amateka maremare yo kwiteza imbere no gukoresha bentonite, ubusanzwe yakoreshwaga gusa.Hariho ibirombe byafunguye mu gace ka Renshou muri Sichuan mu binyejana byashize, kandi abaturage baho bavugaga ko bentonite ari ifu y'ibumba.Irakoreshwa cyane ariko ifite amateka yimyaka irenga ijana.Ubuvumbuzi bwa mbere muri Amerika bwari mu bice bya kera bya Wyoming, aho ibumba ry'icyatsi kibisi ry'umuhondo, rishobora kwaguka muri paste nyuma yo kongeramo amazi, bakunze kwita bentonite.Mubyukuri, imyunyu ngugu nyamukuru ya bentonite ni montmorillonite, hamwe na 85-90%.Ibintu bimwe na bimwe bya bentonite nabyo bigenwa na montmorillonite.Montmorillonite irashobora kugaragara mumabara atandukanye nkicyatsi kibisi cyumuhondo, umuhondo wera, imvi, umweru, nibindi.Irashobora gukora uduce twinshi cyangwa ubutaka bworoshye, hamwe no kunyerera iyo ukoresheje intoki.Nyuma yo kongeramo amazi, ingano yibice bito yaguka inshuro nyinshi kugeza kuri 20-30, igaragara muburyo bwahagaritswe mumazi, no muburyo bwa paste mugihe hari amazi make.Imiterere ya montmorillonite ifitanye isano nimiterere yimiti nimiterere yimbere.

Ibumba rikora

Ibumba rikora ni adsorbent ikozwe mubumba (cyane cyane bentonite) nkibikoresho fatizo, bikorerwa imiti ya aside irike, hanyuma bigakaraba amazi akuma.Isura yacyo ni ifu yera y amata, impumuro nziza, uburyohe, ntabwo ari uburozi, kandi ifite imikorere ikomeye ya adsorption.Irashobora kwamamaza ibintu byamabara nibinyabuzima.Biroroshye kwinjiza amazi mu kirere, kandi kuyashyira igihe kirekire bizagabanya imikorere ya adsorption.Nyamara, gushyushya hejuru ya dogere selisiyusi 300 bitangira gutakaza amazi ya kirisiti, bigatera impinduka mumiterere kandi bigira ingaruka kumyuka.Ibumba rikora ntirishobora gushonga mumazi, kumashanyarazi kama, hamwe namavuta atandukanye, hafi ya yose ashonga muri soda ishyushye ya caustic na acide hydrochloric, hamwe nubucucike bwa 2.3-2.5, no kubyimba gake mumazi namavuta.

Ubutaka busanzwe

Ubusanzwe ibumba ryera ryibumba rifite imiterere yihariye yo guhumanya ni ibumba ryera, ryera ryera ryera rigizwe ahanini na montmorillonite, albite, na quartz, kandi ni ubwoko bwa bentonite.
Ahanini umusaruro wo kubora kwamabuye yikirunga yikirahure, ataguka nyuma yo gufata amazi, kandi agaciro ka pH yo guhagarikwa karatandukanye nu alkaline bentonite;Imikorere yacyo yo guhumanya ni mbi kuruta iy'ibumba ryakozwe.Amabara muri rusange arimo umuhondo wijimye, icyatsi kibisi, icyatsi, ibara rya elayo, umukara, amata yera, umutuku wumutuku, ubururu, nibindi. Hariho bike byera cyane.Ubucucike 2.7-2.9g / cm.Ubucucike bugaragara akenshi buri hasi kubera ubukana bwabwo.Ibigize imiti bisa nibumba ryibumba risanzwe, hamwe nibice nyamukuru bigize imiti ni oxyde ya aluminium, dioxyde de silicon, amazi, hamwe nicyuma gito, magnesium, calcium, nibindi.Bitewe na aside irike ya hydrous silicic, ni acide kuri litmus.Amazi akunda gucika kandi afite amazi menshi.Mubisanzwe, nibyiza cyane, niko imbaraga za decolorisation ziri hejuru.

Ubutare bwa Bentonite
Ubutare bwa Bentonite ni minerval ikoreshwa byinshi, nubwiza bwayo.
