High Quality bentonite with CAS number 1302 - 78 - 9 is a type of absorbent aluminium phyllosilicate clay. It is typically formed from the weathering of volcanic ash. This bentonite product offers high quality and is available at the best price in the market.
Some of its basic physical parameters include: it usually has a fine - grained texture. The color can vary from white, gray, to various shades of brown. It has a high swelling capacity when it comes into contact with water, which is one of its most important characteristics. Chemically, it consists mainly of montmorillonite, a 2:1 type clay mineral with a relatively high cation - exchange capacity (CEC). The CEC of this bentonite can range from approximately 80 to 120 meq/100g, which means it can effectively adsorb and exchange cations.
1. **Drilling Industry**: In the drilling of oil and gas wells, bentonite is used as a component of drilling mud. The high swelling property of bentonite helps in creating a thick, viscous mud that can carry cuttings to the surface, prevent well - bore collapse, and seal the well - bore walls.
2. **Foundry Industry**: It is used as a binding agent in sand molds. Bentonite can improve the strength and stability of the sand molds during the casting process, ensuring high - quality metal castings.
3. **Environmental Remediation**: Due to its high adsorption capacity, bentonite can be used to remove heavy metals and other contaminants from soil and water. It can bind with pollutants, reducing their mobility in the environment.
4. **Cosmetics and Personal Care**: Bentonite is used in some cosmetic products such as facial masks. Its absorbent properties can help in removing excess oil and impurities from the skin.
1. **Preparation for Drilling Mud**: First, measure the appropriate amount of bentonite according to the required viscosity of the drilling mud. Slowly add the bentonite to the water while stirring continuously. Use a high - speed mixer to ensure thorough dispersion. After adding all the bentonite, continue to stir for at least 30 minutes to allow the bentonite to fully hydrate and swell.
2. **In Foundry Applications**: Mix the bentonite with sand in the correct proportion, usually around 3% - 8% by weight depending on the specific requirements of the casting. Add a small amount of water during the mixing process to activate the binding properties of the bentonite. Mix well until a homogeneous mixture is obtained.
3. **Environmental Remediation**: For soil treatment, spread the bentonite evenly over the contaminated soil and then till it into the soil to a certain depth. For water treatment, add the bentonite to the water and stir vigorously. After a period of time, the bentonite with adsorbed contaminants will settle, and the treated water can be separated.
**Drilling Industry Case**: A drilling company in the Middle East was facing problems with well - bore instability during the drilling of an oil well. They decided to use our high - quality bentonite to improve the properties of their drilling mud. After adding the bentonite, the viscosity of the drilling mud increased significantly. This allowed the mud to carry cuttings more effectively to the surface. The well - bore walls became more stable, and the risk of well - bore collapse was reduced. As a result, the drilling process became more efficient, and the overall drilling time was reduced by 15%.
**Foundry Industry Case**: A small - scale foundry in Europe was experiencing issues with the quality of their metal castings. The sand molds were not strong enough, leading to casting defects. They started using our bentonite as a binding agent in their sand molds. By adding 5% bentonite to the sand and following the correct mixing procedure, the strength of the sand molds improved significantly. The number of casting defects decreased by 30%, and the overall quality of the castings improved, leading to increased customer satisfaction and more orders.
