HYSG-19SILICAGEL alumina white beads

Alumino-silica gels, hard white beads with high resistance to crushing and low attrition rate. Because of its large surface area SG-19 alumina beads exhibit a high adsorption for water vapour. The desiccant can be reactivated without significantly impairing the efficiency. It is therefore very conomical, easy to dispose of and without any known adverse effects on the environment.

Applications       
Due to their high adsorptive capacity SG-19 alumina beads have a multitude of uses: Dynamic adsorption (removal of moisture from a continuously lowing gas or liquid stream) as well as static adsorption (removal of moisture and control of humidity in packaging and other enclosed spaces without induced air flow). Due to their special surface structure SG-19 alumina beads are preferably being used for the adsorption of water vapour and as ethyne absorbent for preparation of liquid oxygen or liquid nitrogen and as liquid absorbent or catalyst carrier in oil chemistry，electricity and brewery industry．

Packing            
Airtight in 25 kg – bags,cartons, reconditioned 150 kg

steel drums or 1000 kg-bulk bags with PE-Inliner 

Handling           
SG-18 must always be kept in airtight containers to avoid pre-adsorption with water vapour. Face masks should be used at continual exposure to extensive dusting.
