Properties:
Al Silica gel is colorless or light yellow transparent or translucent spherical particles with a chemical formula mSiO2.nAl2O3.xH2O. It has stable chemical properties, is non-combustible, and insoluble in any solvent except strong bases and hydrofluoric acid. Compared to silica gel with fine holes, it has similar adsorption capacity at low humidity levels (e.g., RH=10%, RH=20%), but 6-10% higher adsorption capacity at high humidity levels (e.g., RH=80%, RH=90%). Additionally, its thermal stability (350ºC) is more than 150ºC higher than silica gel with fine holes, making it ideal for variable temperature adsorption and separation applications.
Application:
Al Silica Gel is primarily used for the adsorption and separation of light hydrocarbons through the dehydration of natural gas. It can also serve as a catalyst and catalyst carrier in the petroleum industry, as well as an industrial desiccant, liquid adsorbent, and gas separation agent.

Discover Color-Changing Silica Gel Catalyst Carriers in bags of 200kg or 500kg by Lianyungang Chemsize International Trading Co., Ltd.
Blue silica gel consists of blue or light blue glassy particles. It can change color from blue to purple and finally to light pink as it absorbs moisture, indicating the humidity level of the environment and the need for replacement. It can be used as a desiccant on its own or in combination with Type A Silica Gel.
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed conditions. When it absorbs moisture, it changes color from blue to red, visually indicating the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps determine the extent of moisture absorption and assesses the relative humidity of the surroundings. It is commonly used as a desiccant for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Product Name: Color-Changing Silica Gel Catalyst Carriers
Description: Cobalt-free silica gel beads in sizes of 1-3mm, 2-4mm, and 3-5mm. Packed in 25kg bags. Ideal for various applications.
The European Union classified cobalt chloride as a Class II carcinogen in 1998, leading to the ban of blue gum containing cobalt chloride in Europe and the United States. To address market demands, cobalt-free environmental discoloration silica gel was developed.
This product, derived from blue gum color-changing silica gel, is made by impregnating fine porous silica gel with an inorganic salt mixture to create orange color-changing silica gel. It utilizes new non-toxic compound dyes, effectively eliminating environmental pollution caused by dyes and discoloration agents. With its original technological conditions and excellent adsorption performance, it stands as a new generation of environmental protection products.
Primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging, this product is ideal for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.
