Specification
QX-150 is a Hydrophilic Fumed Silica with a specific surface area of 150 m2/g. It is a kind of high purity white colloidal powder.
Hydrophilic Fumed Silica is a type of silica that has been treated to be hydrophilic, or water-loving. Silica is a naturally occurring
mineral that is commonly found in rocks and sand. Fumed silica is produced by burning silicon tetrachloride in a flame of hydrogen
and oxygen, resulting in the formation of fine, amorphous silica particles.
The hydrophilic treatment of fumed silica involves modifying the surface of the silica particles to make them more compatible with
water. This is achieved by adding certain chemical compounds or functional groups to the silica surface, which increase its affinity
for water molecules. This modification allows the fumed silica to disperse easily in water and other polar solvents.
Hydrophilic fumed silica has a wide range of applications due to its unique properties. It is commonly used as a thickening and suspending agent in various industries, including paints, coatings, adhesives, sealants, and cosmetics. It can also improve the flow
and rheological properties of liquid systems, enhance the stability of emulsions, and provide anti-settling and anti-sagging effects.
Additionally, hydrophilic fumed silica can be used as a reinforcing filler in rubber and plastic composites, where it improves mechanical properties such as tensile strength and tear resistance. It can also act as a desiccant or absorbent due to its high surface area and
ability to adsorb moisture.
Overall, hydrophilic fumed silica is a versatile material that offers numerous benefits in various applications, primarily due to its
hydrophilic nature and ability to modify the properties of liquid systems.
