Excellent High Purity Inert Alumina Ceramic Balls From Reliable Factory

Production Introduction

Inert alumina ceramic ball has the characteristics of high strength, low water absorption, high chemical stability, high thermal stability, resistance to high temperature and high pressure. It can not only resist the corrosion from the acid, alkali, salt and other organic solvent, but also the temperature change in production process.
Inert alumina ceramic ball is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as the supporting and covering material of catalyst in reactors. Its main role is to increase the distributing spot of gas or liquid, also support and protect the activated catalyst with low strength.

Inert alumina ceramic ball characteristics and advantages

1. High mechanical strength (Monolithic spheres will not split, crack or spall in use)
2. High temperature resistance
3. Lower water absorption
4. Quite excellent chemical stability
5. Can resist corrosion of acid, alkali and other organic solvent
6. Excellent thermal shock resistance (can withstand the temperature urgent changes occurred in production process)
7. Trouble-free reactor filling due to high crush strength
8. Will not plug catalyst bed, optimizing the process efficiency by keeping the pressure drop low and catalyst activity high
9. No contaminate catalyst due to maximize resistance to attrition, extending the catalyst Activity life and reduce the operation cost
