Sodium modification process, equipment and common problems of montmorillonite

Compared with calcium montmorillonite, sodium montmorillonite has better water dispersibility, suspension, expansion, thickening and lubricity, so it has a wider range of uses.

The six major modification methods of bentonite, a general talk, after reading you will understand!

The modification operation of bentonite usually uses physical, chemical and mechanical methods to treat the surface of natural bentonite. According to the required purpose, the physical or chemical properties of the bentonite surface are changed to meet the application of bentonite in different technical fields. At the same time, the function and use value of bentonite can be improved. Some are used to change the characteristics of bentonite and some are used to change a certain ability of bentonite, improve the corresponding ability effect.

How to identify bentonite

In the naked eye identification, high-quality bentonite is pure white, generally gray or light yellow white, often due to water absorption or containing impurities and light green, light green, rose red and other colors. It is still pure white, gray or light yellow white after air drying. After being broken by hand, the section is uneven and jelly-like. There is grease luster, hand touch with slippery feeling.

Technical Introduction of Bentonite

The United States has been leading the research of bentonite in the world, and many standards for domestic bentonite products are based on American standards. Some European countries, Japan and South Korea also have advanced technology in some products. Compared with foreign countries, the development of domestic products and markets is relatively slow, and the products are mainly regular products. This has a lot to do with the domestic environment, policy and resource status.

Application of Bentonite

The nature of montmorillonite has a great relationship with the types of exchangeable cations between layers. According to the types of the main exchangeable cations between layers, montmorillonite is usually divided into calcium montmorillonite and sodium montmorillonite.

The Pulping of Bentonite

The pulping rate is bentonite particles dispersed in water to form a suspension, and the apparent viscosity of this suspension is 15*10-3Ps · s, the number of cubes per ton of bentonite pulp is an important indicator to measure the quality of bentonite, generally sodium bentonite pulp performance is better than calcium bentonite.

The reasons for the different results of water swelling on sodium bentonite and calcium swelling are:

Cations can bind the bentonite particles together and restrict the dispersion of the bentonite particles. The charge density of multivalent ions is larger than that of monovalent ions, and strong electrostatic attraction is generated between particles, which makes the bentonite particles have strong bonding ability. Therefore, the dispersion ability of calcium bentonite is weaker than that of sodium bentonite.

The factors that affect the adsorption of bentonite minerals are:

Effect of bentonite type. The adsorption capacity of sodium bentonite is obviously stronger than that of other types of bentonite minerals such as calcium.

Difference between calcium base and sodium base

The type of interlayer cation of bentonite determines the type of bentonite. When the interlayer cation is Na, it is called sodium bentonite; When the interlayer cation is Ca, it is called calcium bentonite. The properties of sodium montmorillonite (or sodium bentonite) are better than those of calcium. However, the distribution of calcareous soil in the world is far wider than that of sodium soil, so in addition to strengthening the search for sodium soil, it is necessary to modify the calcareous soil to become sodium soil.
