Product Description
Packing Mall 65%-70% Porcelain ceramic ball is in chemical composition70+% alpha alumina and a maximum 0.2wt% SiO2. Because of its high alumina content and low silica (SiO2 ), it's a very excellent and ideal product for high temperature and steam applications, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.
The 65 Alumina Support Media has very excellent thermal properties, with its high density high-temperatur resistance 1450鈩? also it's a good choice for heat retention or equilibration media.
For its superior chemical resistance, it's suitable for applications in olefin processes, such as ethylene dryers, where there's the polymerization problem
Typical application
a) high temperature and steam
b)has very excellent thermal properties, with its high density high-temperature resistance 1450,
c)it's suitable for applications in olefin processes, such as ethylene dryers
