Features of Activated Alumina
 
01/

Porous Adsorption Structure
Activated Alumina is made from high-purity aluminum oxide via high-temperature activation, forming a microporous structure with a large surface area for fast and stable moisture adsorption.

02/

Low Attrition & Stable Operation
This adsorbent is produced through uniform granulation and sintering, creating a dense structure that keeps attrition below 0.1% during long-term use.

03/

High Mechanical Strength and Crush Resistance
The compressive strength of the spheres reaches 90–130 N. Fabricated through sintering to form an α-Al₂O₃ structure, they exhibit excellent resistance to crushing, even in high-velocity airflow environments.

04/

Stable and Versatile Across Multiple Media
Suitable for stable operation in air, natural gas, and liquid systems, retaining its adsorption performance even in high-humidity environments.

 

Quality Control

 

Raw Material Inspection

Each batch of aluminum hydroxide is tested for purity, impurity content, and moisture level before entering production.

Forming Process Control

During extrusion or ball forming, particle shape, size uniformity, and forming integrity are monitored to ensure consistency.

Drying Process Monitoring

Temperature and humidity are strictly controlled to achieve stable pore structure and prevent cracking or collapse.

Calcination Quality Check

High-temperature activation is controlled to ensure proper phase transformation and stable adsorption structure.

Particle Size Screening

Finished product is sieved to ensure uniform particle size distribution according to customer specifications.

Crushing Strength Testing

Mechanical strength is tested to ensure pellets can withstand industrial pressure and long-term operation.

Bulk Density Measurement

Density is checked to ensure stable packing performance in adsorption towers.

Adsorption Capacity Test

Water adsorption performance is tested to verify drying efficiency and operational stability.

Final Inspection Before Packaging

All key indicators are rechecked before packaging to ensure compliance with export and industrial standards.

FAQ

 

Q: What is the primary function of Activated Alumina?

A: Activated Alumina removes moisture and impurities through its porous adsorption structure; it is widely used in compressed air drying, gas purification, and water treatment systems.

Q: Which industries can it be used in?

A: It is applied in industrial dehydration and purification scenarios across various sectors, including petrochemicals, natural gas, compressed air systems, electronics manufacturing, and drinking water treatment.

Q: How should it be loaded?

A: Prior to loading, a dry environment must be maintained. The adsorption tower should be filled evenly to prevent voids that could lead to airflow short-circuiting.

Q: What is the lead time for delivery?

A: Standard specifications typically ship within 7–15 days, while lead times for customized specifications may be slightly longer, depending on production schedules.

Q: What trade terms are available?

A: We support various trade terms, including FOB, CIF, and EXW, and can provide tailored shipping solutions based on the destination port.

Q: What payment methods are accepted?

A: We accept T/T, L/C, PayPal, and Western Union. For bulk orders, a standard payment structure involving an upfront deposit and a final balance payment is typically applied.

Q: How should it be stored?

A: Activated Alumina must be stored in a dry, sealed environment to prevent exposure to atmospheric moisture and ensure the stability of its adsorption performance.

Q: How is it transported?

A: It is typically transported via sea or air freight, utilizing moisture-proof packaging to safeguard product integrity and performance during transit.
