PQ Dry Silica Gel Desiccant Bag: Comprehensive Moisture Control for Small Products

💡 What is Silica Gel?

Silica Gel (Silicic Acid Gel) is a synthetic adsorbent material that typically appears as clear or translucent beads (its primary component is Silicon Dioxide). It is renowned for its unique porous structure, which allows it to absorb water vapor effectively without changing its physical form.

⚙️ The Unique Moisture "Trapping" Mechanism

Silica Gel operates based on the principle of Physical Adsorption (Physisorption):

1. Microscopic Structure: Each Silica Gel bead contains millions of microscopic pores (capillaries) with diameters ranging from just 20 to 50 Angstroms.

2. Adsorption and Retention: As humid air passes by, water vapor is attracted and held within these pores by molecular forces.

3. Non-Melting: This process occurs continuously, yet the bead itself maintains its dry appearance and physical form; it does not melt or liquefy, ensuring absolute safety upon contact with goods.
