Ufa wa dongo wa bentonite wokwera mtengo wotsika mtengo
Calcium bentonite ndi ufa woyera kapena imvi, wosasungunuka m'madzi, mafuta ndi zosungunulira zachilengedwe. Chifukwa cha kuchuluka kwa ma pore ake ogwira ntchito bwino, ali ndi mphamvu yokwanira yothira madzi komanso mphamvu yothira madzi. Sali poizoni, ali ndi mphamvu yabwino yotenthetsera, amathamanga kusefa mwachangu, ndipo mafuta ndi otsika.
Dongo la Calcium bentonite ndi lokongola kwambiri ku China, ndipo ndi mtundu wa organic ammonium compound, ndipo zinthu zopangira ndi bentonite.
Pogwiritsa ntchito kapangidwe ka lamellar ka montmorillonite, Makhalidwe a kutupa komwe kumafalikira mu tinthu ta dongo la colloid m'madzi kapena zosungunulira zachilengedwe, kumapangidwa kuchokera ku ukadaulo wosinthana ma ion ndikuwonjezera chophikira chachilengedwe.

Mapulogalamu
1. Amagwiritsidwa ntchito pa njira yosungunulira ya aliphatic, alkyl, aromatic hydrocarbon, kapena solvent yosakaniza ndi aromatic hydrocarbon ndi viniga, ketone, ester, aether, mowa, ndi zina zotero. Ndi mafuta odzola.
2. Amagwiritsidwa ntchito mu zomatira, phenolic aldehyde, putty ash binder, acrylic painting, cast painting, chlorinated rabara painting, inki (mineral oil), powder coating, asphalt primer, marine painting, antiseptic paint, ndi zina zotero. Katundu wofanana ndi wa International grade: bentonite 27/34/38/57/1000, bentonite -SD2, claytone-MP250, claytone-40 ndi zina zotero.
