Welcome to the official website of Ningcheng Qiyun Bentonite Co., Ltd!
Sodium based bentonite is called when the interlayer cation is Na+; When the interlayer cation is Ca2+, it is called calcium based bentonite; When the interlayer cation is H+, it is called hydrogen based bentonite (active clay, natural bleached clay, acidic clay); Organic bentonite is called when the interlayer cation is an organic cation.

Industrial Indicators of Bentonite
The general industrial requirements for the quality of bentonite ores are measured by the content of montmorillonite in the ores
2023-03-30
In the naked eye identification, high-quality bentonite is pure white, and generally there are gray or light yellow white ones. It often presents light green, light green, rose red, and other colors due to water absorption or impurities. It remains pure white, gray, or light yellowish white after air drying.

Domestic Technology of Bentonite
In the early stage, the research and development of domestic bentonite was mainly concentrated in Zhejiang, and relatively high-end domestic products were also concentrated in this production. The enterprises were represented by Zhejiang Huate and Zhejiang Fenghong.

In 1898, American geologist Knighl discovered a green yellow swelling clay material near the Rocky Mountains River in Wyoming, USA. Due to its origin: "Fort Beton", it was named Bentonite. Bentonite is also known as porphyry or bentonite. The main mineral effective component of bentonite is montmorillonite, with a high grade content of 85-90%. Some properties of bentonite are also determined by montmorillonite.

The properties of montmorillonite are closely related to the types of exchangeable cations between layers. According to the types of main exchangeable cations between layers, montmorillonite is generally divided into calcium montmorillonite and sodium montmorillonite.

The pulping property of bentonite
The pulping rate refers to the dispersion of bentonite particles in water to form a suspension. When the apparent viscosity of this suspension is 15 * 10-3Ps · s, the number of cubic meters of bentonite pulping per ton is an important indicator of the quality of bentonite. Generally, the pulping performance of sodium bentonite is better than that of calcium bentonite.

Bentonite expands when it meets water. The main reason for this natural phenomenon is that the spacing between the crystal layers of bentonite minerals increases, and water molecules enter the crystal layer of the minerals. In addition, the cation exchange effect of bentonite minerals also causes the expansion of bentonite.
