Desiccant 50g/pack

Silica gel desiccant is a physical desiccant with highly active adsorbent material silicon dioxide (chemical formula mSiO₂·nH₂O) as its core component. Below is a detailed introduction:

1. Basic Characteristics

• Chemical Properties: Chemically stable.
• Physical Structure: Features a highly microporous structure and strong adsorption capacity, capable of absorbing moisture up to 30% of its own weight without changing form after absorption.

2. Classification and Special Types

• Conventional Type: Translucent granules, widely used for moisture prevention in instruments, leather goods, luggage, textiles, etc.
• Color-Changing Type (e.g., blue or orange silica gel): Changes color after moisture absorption (e.g., blue → pink, orange → dark green), providing a visual indication of humidity status.

3. Application Fields

• Food and Pharmaceuticals: Used as a food-grade desiccant in packaging for nuts, xylitol, etc., to prevent mold.
• Industrial and Electronics: Protects optical instruments, electronic components, etc., from moisture damage.
• Transportation and Storage: Controls humidity in environments such as containers and sealed glass interlayers, extending the shelf life of items.
• Daily Use Items: Prevents moisture and mold in footwear, hats, handbags, bamboo and wood products, etc.
