Characteristics and uses of micron-sized spherical silica gel

Micron-sized spherical silica gel is an important functional material with a wide range of applications and unique physical and chemical properties.


1. Definition and characteristics


Micron-sized spherical silica gel is a highly active adsorption material, which belongs to amorphous substances and has a chemical formula of mSiO2·nH2O. The main component of this material is silicon dioxide, which has stable chemical properties, does not burn, and is non-toxic. Micron-sized spherical silica gel is a white glass-like transparent spherical particle, insoluble in water and any solvent, and does not react with any substance except strong alkali and hydrofluoric acid.


2. Application fields


Industrial field: Micron-sized spherical silica gel is often used as a desiccant, moisture-proof beads, deodorant and various adsorbents for purifying kerosene, adsorbing aromatics, etc. At the same time, it can also be used as a catalyst and catalyst carrier, and plays an important role in the production of important industrial products such as melamine, phthalic anhydride, maleic anhydride, butadiene rubber, acrylonitrile, etc.


Medical field: Micron-sized spherical silica gel can be made into various medical devices, such as catheters and pipes. Due to its softness, it can effectively reduce the pain of patients and improve the comfort of medical devices.


Consumer goods field: Micron-sized spherical silica gel can be used to make various toys, figurines, etc., and is favored by consumers for its safety and non-toxic properties. In addition, it can also be used as a filler for products such as clothing, tablecloths, and potted plants.


3. Summary


Micron-sized spherical silica gel is an important functional material with a wide range of applications and unique physical and chemical properties. With the continuous development and improvement of preparation technology, it will have broader application prospects in the future.
