Other Products
Color Change Mechanism
Using fine-pore silica gel as the carrier with added indicator, it appears blue before moisture absorption. As moisture absorption increases, the color gradually changes from purple to light red, visually reflecting environmental humidity changes.
Physical Properties
Form: Glass-like spherical or irregular granules, with particle sizes available in 1-3mm, 2-4mm, 3-5mm, 4-8mm, etc.
Moisture Absorption Capacity: Specific surface area ≥600㎡/g, with strong adsorption capability for water vapor.
II. Core Functions and Applications
Dual Functions
· Moisture Absorption and Rust Prevention: Protects metal components of instruments, meters, and equipment in enclosed environments.
· Humidity Indication: Displays relative environmental humidity in real-time through color changes (blue → purple → pink).
Typical Application Scenarios
Field | Usage Examples |
Industrial Equipment | Moisture prevention for transformer breather valves, maintenance of precision instruments |
Consumer Goods | Mold prevention in packaging for leather products, footwear, apparel, and household appliances |
III. Product Specifications and Usage
Common Specifications
· Packaging: 500g/bottle, 20 bottles/box.
· Types: Besides blue, there is also cobalt-free orange silica gel (changes from yellow to green upon moisture absorption, environmentally friendly and non-toxic).
Usage and Regeneration
· Determining End of Life: Replace when it completely turns light red.
· Regeneration Method: Dry at 120°C until it returns to blue, can be reused.
