Product Description

Product Description

Blue Silica Gel Desiccant

Composition & Appearance

Primary Components: Silicon dioxide (SiO₂) + cobalt chloride (CoCl₂) indicator.
Form: Semi-transparent glassy particles (spherical/block, 2–5.6 mm).
Color Dynamics:Dry State: Cobalt chloride exhibits blue (anhydrous CoCl₂).
Hydrated State: Gradual shift to pink (hydrated [Co(H₂O)₆]²⁺) upon moisture absorption.

Key Functional Properties
Moisture-Indicating Mechanism

Reaction: CoCl₂ + 6H₂O → [Co(H₂O)6]²⁺ + 2Cl^-(reversible).
Action Threshold: Full pink coloration signals saturation (requires regeneration/replacement).
Performance Metrics

Moisture Adsorption:≥9.0% at 20% RH | ≥22.0% at 50% RH.
Physical Specs:Particle size compliance ≥95.0% | Bulk density ≥740 g/L.
