Correct Storage And Preservation Of Activated Alumina

2025-08-29

Activated alumina, a material with high adsorption properties and a porous structure, is widely used in gas and liquid drying, purification, and catalysis. Its excellent performance relies heavily on its large surface area and active sites. Therefore, proper storage is crucial to maintaining its adsorption efficiency, physical strength, and extending its service life. Improper storage can lead to premature failure and unnecessary economic losses.

一.Storage Requirements

1. Dry Environment

Priority: Store in a cool, dry, and well-ventilated indoor warehouse.

Contraindications: Storing in the open air is strictly prohibited. Keep away from water sources, wet surfaces, and steam pipes.

2. Sealed

Ensure that the original packaging (usually a woven bag lined with plastic film) is tightly sealed and undamaged.

Unused materials after opening must be immediately re-sealed or transferred to a sealed container to avoid prolonged exposure to the air.

3. Isolation from Contaminants

Store away from chemicals, solvents, acids, alkalis, grease, and other substances.

4. Proper Stacking

It is recommended to use pallets for elevated storage, maintaining a certain distance from the floor and walls to facilitate ventilation and prevent moisture.

Adhere to the "first in, first out" principle, meaning that the first batch in the warehouse is used first. Avoid storing materials for extended periods.

5. Room Temperature

Avoid heat, fire, or direct sunlight. Store at room temperature.

. Consequences of Improper Storage

1.Performance Degradation: Pre-absorption of moisture and impurities from the air significantly reduces actual operating efficiency.

2.Reduced Strength: Moisture may cause powdering, generating dust that can affect system operation.

3.Permanent Failure: Chemical contamination can cause irreversible damage and render regeneration impossible.

. Pre-use Inspection

1.Observe the material for signs of caking or compaction.

2.Smell for any unusual odors (possibly caused by adsorption of organic matter).

3.If obvious signs of moisture are detected, assess the impact on subsequent processes and replace if necessary.
