Appearance:
White spherical silica gel beads.
Product Description:
Water-resistant Silica Gel (FNG) is a high-performance adsorbent specifically developed for applications involving liquid moisture. With outstanding water resistance and excellent hydrothermal stability, it effectively captures liquid water before it reaches the primary adsorbent layer.
Unlike conventional silica gel, which is mainly used for deep adsorption of water vapor, FNG functions as a protective buffer layer in industrial drying systems. It protects the main adsorption bed from liquid water contamination, reduces the risk of adsorbent degradation, and extends the service life of the adsorption system. It is typically combined with H-type Silica Alumina Gel or Fine-pored Silica Gel in multi-layer adsorption beds.
Applications:
Protective buffer layer in industrial adsorption systems
Removal of liquid moisture before the main adsorption bed
Air separation units
Compressed air drying systems
Industrial gas drying and purification
Petrochemical and natural gas processing
Power generation and brewery industries
Packaging:
500 kg or 750 kg jumbo bags
Customized packaging available upon request
Storage:
The product should be stored in a dry place. The outer packaging should not be placed directly on the ground and should be kept on pallets or shelves for isolation. During handling, avoid using sharp hooks that may damage the packaging. During transportation, the product should be protected from rain, moisture, and direct sunlight exposure to prevent any impact on product performance.
