Pub qib bentonite av nplaum hmoov nrog tus nqi pheej yig
Calcium bentonite yog hmoov dawb los yog grey dawb, tsis yaj hauv dej, roj thiab cov kuab tshuaj organic. Vim nws qhov loj ntawm qhov pore, nws muaj peev xwm nqus tau zoo thiab muaj peev xwm nqus tau. Tsis muaj tshuaj lom, ruaj khov thermal zoo, lim dej sai, roj tsawg.
Calcium bentonite av nplaum kuj yog ib qho khoom siv zoo nkauj kub muag hauv Suav teb yog ib hom organic ammonium compound, raw khoom yog bentontie.
Los ntawm kev siv cov qauv lamellar ntawm montmorillonite, Cov yam ntxwv ntawm wswelling tawg mus rau hauv cov av nplaum colloid hauv dej lossis cov kuab tshuaj organic, nws yog ua los ntawm cov thev naus laus zis pauv ion thiab ntxiv cov neeg sawv cev txheej organic.
