The difference between magnesium aluminum silicate and bentonite:
1. Different compositions
Magnesium aluminum silicate is a white composite colloidal substance.
Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 crystal structure composed of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedrons.
2. Different properties
The moisture content of magnesium aluminum silicate is less than 8. Non-toxic. Tasteless. Insoluble in water. Dispersed in water. The pH value is 7.5~9.5. Good rheology and thixotropy.
Bentonite adsorption can be divided into three types: physical adsorption, chemical adsorption and ion exchange adsorption.
3. Different applications
Magnesium aluminum silicate is used as a stabilizer, suspending agent, and thickener in personal care (such as toothpaste), cosmetics, medicine, pesticides, polishes, Lubricants, coatings, paints, lithium batteries, engineering plastics and other fields.
my country has a long history of developing and using bentonite, which was originally used as a detergent. It is actually widely used but only has a history of a hundred years.
