Pub qib bentonite av nplaum hmoov nrog tus nqi pheej yig
Calcium bentonite yog cov hmoov dawb lossis grey dawb, insoluble hauv dej, roj thiab cov kuab tshuaj organic.Vim nws cov pore loj npaum li cas, nws muaj peev xwm adsorption muaj zog thiab muaj peev xwm adsorption.Tsis muaj tshuaj lom, zoo thermal stability, ceev lim ceev, roj tsawg.
Calcium bentonite av nplaum kuj yog cov tshuaj pleev ib ce zoo kub muag hauv Suav teb yog ib hom organic ammonium compound, raw khoom yog bentontie.
Los ntawm kev siv montmorillonite lub lamellar qauv, Cov yam ntxwv ntawm wswelling disperse mus rau hauv colloid av nplaum particle nyob rau hauv dej los yog organic solvents, nws yog tsim los ntawm ion exchange technology thiab ntxiv cov organic txheej.
