High-purity alumina fillers mainly include: ceramic filler balls, ceramic Raschig rings, etc. The product uses alumina superfine powder as the main raw material, and is fired by advanced molding process and high temperature tunnel kiln. Widely used in petroleum, chemical industry and other industries as tower packing balls, catalyst carriers, hydrogenation refining devices, catalytic reforming devices, isomerization devices, etc. The demethylation device is used as the bottom filling material. It has the characteristics of high temperature resistance, high pressure, low water absorption, stable chemical properties, can withstand the corrosion of strong acids and alkalis and other organic solvents, and can adapt to different temperature changes.
The ceramic filler ball has the characteristics of high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, and good thermal shock resistance. It is mainly used in the working environment of high temperature, high pressure and strong corrosiveness in the petrochemical industry.
