Bentonite
Bentonite is a kind of clay of montmorillonite clay with a purity 96% plus.
The structure of montmorillonite is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedrons and a layer of aluminum-oxygen octahedron. There are some cations in the layered structure formed by the unit cell of montmorillonite. When the inter-layer cation is Na+, it is called sodium bentonite; when the inter-layer cation is Ca2+, it is called calcium bentonite; when the inter-layer cation is an organic cation, it is called organic bentonite.
1. It has strong selective adsorption on viruses, pathogens and toxins in the digestive tract.
2. Montmorillonite can be used as filter, emulsifier, adhesive and excipient.
3. Carrier montmorillonite can make intestinal repellent.
