High / Low Alumina Ceramic Ball as Inert Carrier Bed Support
We Pingxiang chemshun ceramics Co., Ltd a professional enterprise with 18 years manufacturer and export for the catalyst support matieral, chemical packings, wear-resistance ceramics.
Inert aluminum oxide ceramic balls are widely used in many fields, including petroleum, chemical engineering, fertilizer production, gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers.
They have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process.
The main role of inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.
