Coarse Mesh Microglobular Silica Gel

Chemical Formula:

SiO2·nH2O
Properties:
a kind of transparent or semi-transparent globular granule with silicon-oxygen tetrahedron as its mainbody, provided with high specific surface, high impact strength, good resistance to abrasion, good thermal stability and resistance to acids (except hydrofluoric acid). It is soluble in thick caustic soda and can adsorb vapor, other gases and solvents.
In addition, our coarse mesh microglobular silica gel is a kind of high-performance catalyst carrier, provided with high activity and long life. It has always been applied to boiling bed for a long time. It has ever been evaluated as "high quality product".
Uses:
mainly used as the catalyst carrier for petrochemical like phthalic anhydride and aniline. It can selectively adsorb and separate some organic gases and liquids
Packing:
round pasteboard drum or woven bag lined with polythene bag, net weight 20kg.
Delivery and Storage:
keep it in dry and ventilating warehouse and protect it against moisture and highly volatile matter.
