Bentonite for Sale
HOO CHEMTEC’s bentonite desiccant utilizes a controlled thermal activation process to enhance its natural crystalline structure, ensuring maximum moisture absorption efficiency.
- Environmentally Friendly and 100% Natural: Our bentonite is directly derived from nature, making it a green and environmentally friendly solution. It is biodegradable and can be safely returned to the soil after use without special chemical treatment.
- Uniform Adsorption Performance: Unlike some rapidly saturating synthetic desiccants, bentonite maintains a stable adsorption rate across a range of temperatures, ensuring long-term protection during intercontinental transport.
- Non-Corrosive and Neutral: Due to the chemical stability and neutral pH of our bentonite, it will not corrode metal parts or damage sensitive fabrics, even when the packaging bag is in direct contact with the product.
- Economical and Effective Protection: Bentonite is significantly cheaper than silica gel per unit of moisture absorption, making it ideal for high-volume industrial packaging.
What is Bentonite Used for
- Drilling Fluids: It is widely used in the oil and gas industry as a key component of drilling fluids to lubricate and cool the drill bit, remove cuttings, and stabilize boreholes.
- Foundry Sands: Bentonite is utilized in foundry molds and cores to improve their strength, casting precision, and resistance to high temperatures.
- Cat Litter: Bentonite-based cat litter is popular due to its exceptional clumping and odor-absorbing properties.
- Civil Engineering: It finds application in civil engineering for sealing and waterproofing purposes in construction, such as lining ponds, landfills, and canals.
- Environmental Remediation: Bentonite is used in environmental remediation to seal and control pollution in landfills and contaminated sites.
- Iron Ore Pelletizing: It is added to iron ore concentrate to improve pellet green strength and prevent sticking during the pelletization process.
- Binder in Pelletizing: Bentonite is used as a binder in the pelletizing process of various materials, such as fertilizers and detergents.
- Wine Clarification: It is employed in winemaking to remove protein haze and clarify wine.
FAQ of Bentonite
Yes. Our bentonite is non-toxic and neutral. We provide specific food-grade packaging that complies with FDA and international safety standards for indirect food contact.
No. Unlike calcium chloride, which turns into a liquid (brine) as it adsorbs moisture, bentonite remains a solid granule. There is zero risk of leakage or “sweating” that could damage your goods.
Yes, you can use bentonite desiccant with a laptop, and it is actually a highly recommended practice for long-term storage or travel in humid climates.
Packing: 25kgs/bag or as custmer’s request.
Bentonite needs to be stored in a cool, dry, well-ventilated place and placed in a sealed container to prevent moisture absorption.
