Bentonite yog cov khoom siv tsis yog hlau nrog montmorillonite ua cov khoom tseem ceeb. Cov qauv montmorillonite yog 2: 1 siv lead ua qauv uas muaj ob lub silicon oxygen tetrahedrons thiab ib txheej ntawm txhuas oxygen octahedron. Muaj qee cov cations, xws li Cu, Mg, Na, K, hauv cov qauv txheej txheem tsim los ntawm montmorillonite crystal cells, thiab kev sib cuam tshuam ntawm cov cations no thiab montmorillonite crystal cells tsis ruaj khov heev, uas yooj yim pauv los ntawm lwm cov cations Nws muaj cov khoom pauv ion zoo. Cov teb chaws txawv teb chaws tau siv rau hauv ntau dua 100 lub chaw haujlwm hauv 24 thaj chaw ntawm kev lag luam thiab kev ua liaj ua teb, nrog ntau dua 300 yam khoom, yog li tib neeg hu nws tias "universal av".
Bentonite muaj ntau qib xws li:Av nplaum nquag, Av dawb huv, Organic bentonite, Bentonite ore, Calcium bentonite thiab sodium bentonite.
Vim nws cov khoom zoo thiab tshuaj lom neeg, bentonite siv tau ua decolorizer, binder, thixotropic agent, suspending agent, stabilizer, filler, pub, catalyst, thiab lwm yam. Nws yog dav siv hauv kev ua liaj ua teb, kev lag luam teeb pom kev zoo, tshuaj pleev ib ce, tshuaj thiab lwm yam teb.
