Product Description

Product Description

Cobalt-Free Environmental Discoloration Silica Gel

Properties

The European Union classified cobalt chloride as a Class II carcinogen in 1998. Blue gum containing cobalt chloride has been banned in Europe and the United States. To address market demands, cobalt-free environmental discoloration silica gel was developed.

This product is a new generation environmental protection solution based on blue gum color-changing silica gel. It is made from fine porous silica gel infused with an inorganic salt mixture to create orange color-changing silica gel. The use of non-toxic compound dyes eliminates pollution from traditional dyes and discoloration agents.

With its original technological conditions and excellent adsorption performance, this product offers superior environmental benefits.

Application

This silica gel is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is ideal for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.

Blue Silica Gel Product Description

Blue Silica Gel

Blue silica gel is an ideal primary desiccant that can be used alone or blended with other desiccants for applications requiring visual moisture control. Chemsize silica gel beads are saturated with a moisture indicating solution, turning deep blue when dry and changing to purple and pink as they adsorb moisture.

Features:

• Chemical Formula: SiO₂· nH₂O + CoCl₂


• Narrow pore silica gel with interconnecting pores of 20-30 nanometers


• Effective moisture removal up to 220°F, best used at room temperature and high relative humidity

Typical Applications:

• Compressed air dryers


• Gas drying


• Breathers


• Packaged goods

Type A Silica Gel

Type A silica gel is a transparent or translucent particle with the chemical formula mSiO₂.nH₂O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions, with high mechanical strength and good wear resistance.

Specifications:

• Average pore diameter: 2.0-3.0nm


• Surface Area: 650-800m²/g


• Pore Volume: 0.35-0.45ml/g

Applications:

Mainly used for drying and moistureproof, can also serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.
