Beads Design
Uniform spherical particles. Large specific surface area. Fast moisture absorption rate. Its saturated moisture absorption rate can reach more than 30% (90% RH environment), far exceeding fiber or clay desiccant. The gap between the beads is uniform to ensure air circulation. Thus, the white silica gel beads can quickly balance the humidity in a closed space, and achieve precise humidity control.
Safety and Adaptability
Our white silica gel beads have significant advantages in safety and adaptability. Firstly, it adopts a neutral dust-free design, and it meets FDA food contact standards. Therefore, this desiccant can be directly used in areas with strict hygiene requirements, such as food and medicine, ensuring high safe and worry-free use.
Secondly, these beads have a unique spherical particle structure and a smooth surface without edges and corners. During the moisture-proof process, it will not damage precious items such as precision instruments and optical lenses due to friction, achieving a perfect combination of safety protection and item protection.
Regeneration Capability and Cost Advantage
These white silica gel beads can be fully regenerated by heating at 105℃-120℃ for 2-3 hours. The recovery rate is over 95%. It can be reused many times without affecting the moisture absorbing effect. Combined the recyclable feature with its efficiency of up to 30%, this desiccant reduces the long-term use cost by more than 60%, compared with traditional desiccants. Therefore, it is particularly suitable for industrial production and storage scenarios that require continuous moisture protection, achieving a perfect balance between efficient moisture protection and economy.
