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 of environmental protection products based on blue gum color-changing silica gel. It is made from orange color-changing silica gel, which is created by impregnating fine porous silica gel with an inorganic salt mixture and using non-toxic compound dyes to eliminate pollution caused by dyes and discoloration agents.

Application

This product is primarily used as a desiccant and to indicate desiccant saturation levels in sealed packaging. It is also suitable for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.

Blue Silica Gel

Blue silica gel is an ideal primary desiccant, perfect for applications requiring visual control of moisture. 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.

Chemical Formula: SiO₂· nH₂O + CoCl₂

Properties: Narrow pore silica gel with interconnecting pores of 20-30 nanometers, utilizing physical adsorption and capillary condensation to trap and hold moisture. Effective up to 220°F, best used at room temperature (70-90°F) and high relative humidity (60-90% Rh).

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: Primarily used for drying and moistureproofing, as well as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.
