Alumina Ceramic Filler High Alumina Inert Ball/99% alumina ceramic ball

Chemical filler ball properties: alias alumina ceramic ball, filler ball, inert ceramic, support ball, high-purity filler. Chemical filler ball application: widely used in petrochemical plants, chemical fiber plants, alkyl benzene plants, aromatics plants, ethylene plants, natural gas and other plants, hydrocracking units, refining units, catalytic reforming units, isomerization units, demethylation units Underfill materials such as devices. As a support covering material and tower packing for catalyst, molecular sieve, desiccant, etc. in the reactor. Its main function is to increase the distribution point of gas or liquid to support and protect the active catalyst with low strength. Features of chemical filler balls: high purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal shock stability, and stable chemical properties. Specifications of chemical filler balls: 3mm, 6mm, 8mm, 9mm, 10mm, 13mm, 16mm, 19mm, 25mm, 30mm, 38mm, 50mm, 65mm, 70mm, 75mm, 100mm.
