The alumina packing ball takes super fine alumina powder as main raw materials and shaped by Isostatic pressures and rolling machinery and baked in tunnel kiln by high temperature. It is widely used as the packing and activator, catalyst in petroleum and chemical industry. It is suitable for chemical fiber factory, alkyl benzene factory, aromatic hydricarbon factory, ethylene factory, natural gas factory etc.
With features of high strength, good high temperature and high pressure resistance, strong acid-alkali and erosion resistance and good heat shock stability. This product is specially used in high temperature, high pressure and strong erosion environment.
