Precision Electronics
Solution: ESD Anti-Static Montmorillonite Desiccant (Surface Resistance 10⁶–10⁹Ω)
Key Effect: Maintains humidity inside packaging below 10% continuously, effectively preventing SMT component oxidation failure.
Precision Electronics
Solution: High Moisture Absorption Rate-Controlled Calcium Chloride Desiccant (Saturated Absorption ≥300%)
Key Effect: Sets absorption rate based on packaging and storage duration to prevent cell failure due to moisture.
Precision Electronics
Solution: Carbon-Oxygen Desiccant (Resists 100°C High Temperature, No Back-Seepage, No Expansion)
Key Effect: Prevents lens fogging and maintains stable optical performance.
Precision Electronics
Solution: Silica Gel Desiccant (FDA Certified, Safe for Contact with Food and Medicine)
Key Effect: Physical moisture absorption, safe and non-toxic, complies with food and pharmaceutical packaging standards.
Precision Electronics
Solution: High Moisture Absorption Rate-Controlled Magnesium Chloride Desiccant (Clumps Without Liquefying, Safe No Back-Seepage)
Key Effect: Adjusts absorption rate to ensure long-term reliability of vehicle lights in humid environments.
Precision Electronics
Solution: High Moisture Absorption Calcium Chloride Desiccant (72-Hour Absorption ≥200%)
Key Effect: Prevents container condensation and “container rain,” protecting cargo from moisture during shipping.
Market Issues & Compliance Identification Guide (Moisture-Proof Example)
When selecting desiccants, require suppliers to provide compliant test reports and consider sending samples to third-party labs for verification to avoid risks from non-compliant products.
Desiccant Type
Standard Requirements
Common Issues
Risk Alert
Silica Gel Desiccant
Moisture Absorption Rate ≥30% (25°C, RH90%), Moisture Content ≤5%
1. Water injection to increase weight, reducing absorption performance
2. Use of recycled silica gel with chemical residues
3. Counterfeiting with glass beads, etc., having no absorption capability
Performance non-compliance, product corrosion, environmental risks
Bentonite Desiccant
Moisture Absorption Rate ≥13% (25°C, RH40%), Moisture Content ≤3%
1. Use of low-quality or recycled montmorillonite
2. Adding calcium chloride to boost performance, causing back-seepage and corrosion after absorption
Insufficient absorption rate, liquid seepage damaging products
Activated Clay Desiccant
No unified national standard; relies on enterprise standards
1. Made from clay mixed with small amounts of mineral soil, with very low absorption rate
2. Adding calcium chloride to increase apparent absorption rate
Poor actual moisture-proof effect, high back-seepage risk
