Characteristics
Color : light yellow.
Chemical molecular formula: SiO2.nAl2O3.xH2O.
It-is chemically stable£¬flame-resisting£¬insoluble in any solvent except strong alkali or hydrofluoric
acid£®Superficial polarity£¬thermal stability£¬performance of adsorption and separation are all better than
that of fine-pored silica gel£®
Use
With higher surface area and drying ability£¬the absorbent is being widely used in many fields£®For
its higher compression strength and lower rattle loss,it has longer life and higher performance-value
ratio than fine-pored silica gel£®
Main application£º
1.drying of gas
2.drying of natural gas
3.drying of liquid gas
4.drying of compressed air
