fine pored silica gel
CHARACTER:
1.
Fine-pored silica gel includes fine-pored spherical silica gel and fine-pored lumpy silica gel.
2.Narrow spherical silica gel is colorless or slightly yellow transparent or semitransparent granular in substance, narrow lumpy silica gel is colorless or slightly yellow transparent or semitransparent Irregular granular in substance.
3.Fine-pored silica gel is also called Type-A silica gel.


USAGE:
1.
Mainly used for drying and moisture proof, may also be used as catalyst carriers, adsorbents, separators and variable-pressure adsorbents, etc.

2.Widely used to protecting instruments, weaponry, electronic equipment, medicine, foodstuff, textile products and other packed material from moisture. It can prevent items from moisture, mildewing and rusting. Because of its high packing density and effective moisture absorption under low humidity, it is used for the purification of air.

3.Also it is often used in ocean shipment to keep goods from the damage caused by excessive humidity.
