High Intensity Talc Ceramics 3mm-70mm Alumina Ceramic Balls
alumina chemical filling ball high purity filling material abrasive medium catalyst covering material
Product name : Alumina ceramic ball
Specification : HY-TCQ-03
Product use :
widely used in petrochemical plants, chemical fiber plants, alkylbenzene plants, aromatics plants, ethylene plants, natural gas and other workshops hydrocracking unit, refining unit, catalytic reforming unit, isomerization unit, demethylation unit and other bottom filling materials. It is used as a support covering material and tower packing for catalysts, molecular sieves, and desiccants in the reactor. Its main role is to increase the gas or liquid distribution point, support and protect the catalyst strength is not high.
Characteristics : high purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal shock stability, stable chemical properties.
