Water-resistant silica gel 2-5mm is a spherical granular material specifically designed for industrial gas drying and adsorption, featuring high water resistance and mechanical strength. It is widely used in air separation, petrochemicals, and other fields. Below are its core characteristics and applications:

Product Characteristics

1. Physical Form

   • White or gray spherical particles with a particle size range of 2-5mm, exhibiting good fluidity.
   • Coarse pore structure (FNG-C type), large pore size, high adsorption efficiency, and a non-cracking rate in water ≥90%.

2. Chemical Performance

   • Resistant to acids, alkalis, and solvents, with excellent thermal stability (withstands temperatures up to 600°C).

3. Mechanical Strength

   • High compressive strength, low regeneration breakage rate, and long service life.

Main Applications

• Gas Drying and Purification
  Used for drying compressed air, liquid air/oxygen, and adsorbing impurities such as acetylene and carbon dioxide.
• Catalyst Carrier
  Serves as a liquid adsorbent and catalyst carrier in petrochemical and power industries.
• Water Purification
  Removes pollutants in industrial water treatment and acts as a pre-stage buffer drying for molecular sieve protection beds.

Typical Application Scenarios

• Air separation processes in air separation units.
• Liquid adsorption and moisture protection in the brewing industry.
• Air source purification devices in locomotive and vehicle systems.
