Physical and Chemical Characteristics
1. Swelling capacity: After bentonite adsorbs water or organic molecules, the spacing between the crystal layers increases, and the volume expansion can reach 20-25 times. Calcium montmorillonite has higher hydration energy and faster water absorption rate than sodium montmorillonite, but its final water absorption rate and expansion ratio in aqueous media are much lower than those of sodium montmorillonite. Both can be used as anti-seepage, sealing materials, water absorption, waterproofing materials, soil water and fertilizer retention agents in industry.
2. Dispersive suspension and flocculation properties: Bentonite is dispersed into a colloidal form in water and has good suspension and rheological properties. After dispersion, montmorillonite flakes can produce layer layer aggregation or end face and end face layer aggregation under different pH conditions. When flocculation develops to the whole system, it becomes gel with good thixotropy. When the agglomeration continues to develop to a certain extent, the particles increase and precipitate. Used as a suspension agent, thickener, and lubricant for drilling or non excavation pipe jacking construction in industry, including flame retardants, drugs, and daily necessities.
3. Cation exchange and adsorption properties: In water with pH of 7, the cation exchange capacity of montmorillonite is 70-140 mmol/100 g. The huge internal and external specific surface area (≈ 800 m2/g) and excellent cation exchange ability make it have strong physical adsorption, chemical adsorption, and cation exchange adsorption capabilities, which can adsorb water molecules and organic molecules; It can be used as a treatment agent for radioactive and heavy metal wastewater or organic cationic organic printing and dyeing wastewater, catalyst carrier, drug or drug carrier, fertilizer slow-release agent, decolorization or adsorption agent, deodorant, soil heavy metal remediation agent, and so on. By utilizing cation exchange properties, calcium based bentonite can be modified into sodium based bentonite to prepare organic bentonite, cross-linked or pillared montmorillonite, etc.
4. Deformability and Bonding: Bentonite has good deformability, with plastic and liquid limits greater than kaolin and illite, reaching 83-250, and also has good bonding properties. Compared with sodium based bentonite, calcium based bentonite has poorer adhesion. Bentonite is used as a binder for iron ore pellets during steel smelting, and as a binder for molding sand during mechanical component casting.
Application
Bentonite has good physical and chemical properties such as adhesion, adsorption, catalysis, suspension, dispersion, thixotropy, and cation exchange. It can be widely used in bellow applications.
● Montmorillonite powder API : used as an antidiarrheal drug.
● Excipients: can be used as excipients.
● Filter agent: In production, it can act as an adsorbent and filter.
● Emulsifier: can be used as a thickener for ointments and pastes, or directly as a base material for ointments and emulsifiers.
● Adhesive: Montmorillonite has a certain viscosity and can be used to bond powder.
● Carrier montmorillonite: In chemical synthesis, it can serve as a catalyst carrier.
