Classification of inorganic Colloidal Silica

Colloidal Silica according to the size of its aperture is divided into: a large pore silica gel, wide pore Colloidal Silica ,B-type silica gel, porous Colloidal Silica. Because the different pore structure, so they have their own characteristics of adsorption. Coarse-pored silica gel in the case of high relative humidity with high adsorption capacity, pore  Colloidal Silicain the case of low relative humidity adsorption capacity than coarse-pored Colloidal Silica, Colloidal Silica as the B-type pore structure between the coarse and fine hole between the amount of adsorption between the thick, between the pore. Inorganic silica gel according to their uses, but also can be divided into beer silica gel, silicone PSA, medical silicone, ,Colloidal Silicadesiccant, silica gel opening agent, toothpaste with silica gel. Pore  Colloidal Silicafor drying, moisture-proof, rust-proof. Prevent the equipment, instruments, weapons, ammunition, electrical equipment, pharmaceuticals, food, textiles and other types of packaging materials exposed to moisture, can also be used as catalyst carrier and refined organic compounds dehydration. Because of its high packing density and low humidity, moisture absorption obvious characteristics that can be used as air-purifying agent to control the air temperature. In the sea on the way there are a wide range of applications, since the goods in transit often large and moisture deterioration due to temperature, the product can be an effective desiccant moisture, so the quality of goods is guaranteed. Pore Colloidal Silica is also commonly used between two parallel plates sealed windows dehumidification, two layers of glass can maintain brightly lit degree.
Also known as C-type coarse-pored  Colloidal Silica is a gel, is a highly active adsorption material, is a coarse-pored silica gel
Amorphous material, its chemical formula is mSiO2 · nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. Coarse-pored  Colloidal Silicachemical components and physical structure, determines that it has many other features too difficult to replace similar materials: adsorption properties, thermal stability, chemical stability, high mechanical strength. The appearance of coarse-pored  Colloidal Silicais white, there are massive, spherical and spherical micro-three categories of products. Coarse pore silica gel is mainly used for gas purification, desiccant and acid agents in addition to insulating oil; coarse pore Colloidal Silica is mainly used for bulk catalyst, desiccant, gas and liquid cleaning agent.Read more：http://www.chemical-chem.com/Papermaking-chemicals/Colloidal-Silica/
