Sodium bentonite is classified according to the type and content of exchangeable cations between the montmorillonite layers. Those with an alkalinity coefficient greater than or equal to 1 are sodium bentonite, and those with an alkalinity coefficient less than 1 are calcium bentonite. Sodium bentonite is also relatively speaking.
Compared with calcium-based or magnesium-based bentonite, sodium-based bentonite has superior physicochemical properties and technological performance. Mainly manifested in: the water absorption speed of Chemicalbook is slow, but the water absorption rate and expansion ratio are large; the cation exchange capacity is high; the dispersibility in water medium is good, the colloid price is high; its colloidal suspension has good thixotropy, viscosity, lubricity, and pH High value; good thermal stability; high plasticity and strong cohesiveness; high thermal and wet tensile strength and dry compressive strength. Therefore, the use value and economic value of sodium bentonite are relatively high.
Application
1. In drilling, a drilling mud suspension with high rheology and thixotropic properties is configured.
2. In mechanical manufacturing, it can be used as foundry sand and binder, which can overcome the phenomenon of "sand inclusion" and "skinning" of castings, reduce the rate of casting rejects, and ensure the accuracy and smoothness of castings.
3. Used as a paper filler in the paper industry to enhance the brightness of paper.
4. Used as antistatic coating in textile printing and dyeing liquor, instead of starch sizing and printing coating.
5. In the metallurgical industry, bentonite is used as a binder for iron ore pellets to make the particle size of the agglomerate uniform and good in reducing performance. This is the largest use of bentonite. The bentonite used is mainly sodium bentonite; in the petroleum industry, sodium bentonite is used Used in the preparation of tar-water emulsion; in the food industry, sodium bentonite is used for decolorization and purification of animal and vegetable oils, wine and juice clarification, beer stabilizers, etc.; in the textile printing and dyeing industry, sodium bentonite is used as a filler and bleaching agent , Antistatic coating, can replace starch sizing and printing paste.
