The main difference between calcium bentonite and sodium bentonite is the difference between interlayer cations. The interlayer cation of calcium bentonite is Ca2. I will introduce its physical properties and its application.
The physical properties of calcium bentonite is that it is white or off-white powder, insoluble in water, organic solvents and oils, and has a large effective pore volume, so it has better adsorption capacity and larger adsorption capacity. The calcium-based bentonite is non-toxic, the filtration speed is relatively fast, the oil rate is relatively low, and the thermal stability is also relatively good.
Calcium-based bentonite as a binder, decolorant, adsorbent, catalyst, thickener, thixotropic agent used in chemical industry, metallurgical pellets, casting, drilling and other industries, as a binder in asbestos insulation applications, calcium-based bentonite used in radioactive waste do absorbent.
