What is bentonite used for
Bentonite is a clay mineral with montmorillonite as its main component. Due to its unique physical and chemical properties, it is widely used in many fields such as industry, agriculture, environmental protection, and construction. This article will introduce the use, classification and related data of bentonite in detail based on popular topics and hot contents throughout the network for the past 10 days.
1. The main uses of bentonite
The main uses of bentonite can be divided into the following categories:
| Application areas | Specific use | Popular index (last 10 days) |
|---|---|---|
| industry | Casting, metallurgy, petroleum drilling, chemical catalysts | ★★★★☆ |
| agriculture | Soil improvement, feed additives, pesticide carriers | ★★★☆☆ |
| Environmental friendly | Wastewater treatment, anti-seepage materials in landfills | ★★★★★ |
| architecture | Waterproof materials, coatings, mortar additives | ★★★☆☆ |
| Daily edible | Cosmetics, skin care products, detergents | ★★☆☆☆ |
2. Classification of bentonite
According to its cation exchange capacity, bentonite is mainly divided into sodium-based bentonite and calcium-based bentonite. Here is a comparison of the main characteristics of the two bentonites:
| type | cation | Expansion | Main uses |
|---|---|---|---|
| Sodium-based bentonite | Na+ | high | Casting, oil drilling, environmental protection |
| Calcium-based bentonite | Ca2+ | Low | Agriculture, construction, daily chemical |
3. Popular application cases of bentonite
1.Environmental protection field:Recently, the application of bentonite in wastewater treatment has become a hot topic. Because of its strong adsorption capacity, bentonite is widely used to treat heavy metal wastewater. An environmental protection company used bentonite modified materials to successfully increase the removal rate of heavy metals in wastewater to more than 95%.
2.Agricultural field:As a soil improver, bentonite can effectively improve the soil structure and improve the soil's water and fertilizer retention ability. Recently, bentonite-based soil modification agents launched by an agricultural technology company have been widely praised in the market and are especially suitable for arid areas.
3.Industrial field:In oil drilling, bentonite, as an additive to drilling fluid, can effectively lubricate the drill bit and stabilize the well wall. Recently, an oil company announced that it would expand its bentonite procurement to cope with the growth in global oil demand.
4. Market data of bentonite
The following are the market data related to bentonite in the past 10 days:
| Data indicators | Value | Year-on-year growth |
|---|---|---|
| Global bentonite market size | $1.5 billion | 5.2% |
| China's bentonite yield | 3.5 million tons | 4.8% |
| Comparison of application in the field of environmental protection | 30% | 8.3% |
| A proportion of application in agriculture | 20% | 3.5% |
5. Future development trends
With the improvement of environmental protection requirements and technological advancement, the application field of bentonite will be further expanded. Especially in the fields of environmental protection and new energy, the demand for bentonite will continue to grow. In addition, the modification technology of bentonite will also become a research hotspot to improve its performance and scope of application.
