Product Description
Inert alumina ceramic balls are industrial ceramic packing materials made primarily from high-purity alumina through high-temperature sintering. They are widely used in reactors in industries such as petrochemicals, fertilizers, natural gas processing, and environmental protection as catalyst support packing.
Inert alumina ceramic balls are typically used to support catalyst beds, disperse gas or liquid flow, and protect the catalyst from gas flow impact. They possess high mechanical strength, high temperature resistance, and excellent chemical stability, enabling long-term stable operation under high temperature, high pressure, and corrosive environments.
Due to their low water absorption, dense structure, and high compressive strength, inert alumina ceramic balls exhibit excellent stability in industrial catalytic reaction units, making them an ideal choice for reactor packing and catalyst support materials.
Product Features
1. High Mechanical Strength: Inert alumina ceramic balls possess excellent compressive strength, capable of withstanding the weight of the catalyst and the impact of airflow in the reactor, and are not easily broken.
2. Excellent High-Temperature Resistance: The product can be used stably for a long time in high-temperature environments, with a temperature resistance exceeding 1500℃.
3. Good Chemical Stability: It exhibits good corrosion resistance to acids, alkalis, and most chemical media.
4. Low Water Absorption: The dense structure and low water absorption ensure long-term stable operation.
5. Uniform Size: Good sphericity and uniform particle size are beneficial for the uniform distribution of gas and liquid in the reactor.
