Features of Silica Gel
High Hygroscopicity
Utilizing a porous silica structure with a high specific surface area of 650–750 m²/g, this Silica Gel rapidly reduces humidity within sealed environments, making it ideal for moisture protection during long-distance transport.
High Strength
Featuring a spherical structure, it boasts a compressive strength of ≥180N and an abrasion rate of ≤0.1%, ensuring it remains intact and resistant to breakage during transit.
Color-Change Indication
The blue or orange gel varieties change color to red or green upon absorbing moisture, providing a visual indicator of the desiccant's saturation status and facilitating easy determination of when replacement is required.
Versatile Compatibility
Available in multiple types—including A, B, C, H, and WS—this product is suitable for a wide range of conditions, from low-humidity to high-humidity and specialized aquatic environments, serving industries such as electronics, food, and chemicals.
Quality Control
Raw Material Purity Testing
Prior to production, silica purity and impurity levels are tested to ensure that fundamental adsorption performance and chemical stability meet established standards.
Particle Size Screening
Multi-stage vibrating screens are utilized to control the particle size range, ensuring a uniform distribution within the 1–5mm range and minimizing the proportion of broken particles and fine dust.
Specific Surface Area Testing
Specific surface area is measured to guarantee the integrity of the microporous structure, thereby ensuring consistent moisture absorption efficiency right from the source.
Pore Structure Consistency Testing
Pore size distribution is strictly controlled to prevent fluctuations in moisture absorption rates caused by structural irregularities.
Factory Moisture Content Control
Prior to shipment, the initial moisture content is strictly controlled to remain ≤3%, preventing premature loss of efficacy during transit and storage.
Adsorption Performance Sampling
Random sampling of moisture absorption capacity is conducted on a batch-by-batch basis to ensure stable and consistent adsorption performance under standard humidity conditions.
Mechanical Strength Testing
The compressive strength of the particles is tested to ensure they resist pulverization and breakage during transportation and usage.
Packaging Seal Integrity Testing
Packaging bags undergo airtightness inspections to prevent moisture ingress or leakage during transit.
