Recently, hydrophilic silica, as a high-performance material, is gradually receiving widespread attention. Hydrophilic silica usually refers to gas phase silica that has not been treated with any chemical reagents, and its surface retains a large number of hydroxyl groups, thus having excellent hydrophilicity. This feature has shown great potential for application in multiple fields.
Hydrophilic silica is an ideal choice for water-based systems due to its unique surface properties. It can be wetted by water and dispersed in water, which makes it widely used in various industries such as coatings, paints, adhesives, sealants, etc. In addition, hydrophilic silica is also used in unsaturated polyester, film, ink, silicone rubber, cosmetics, pharmaceuticals, and food industries, and its versatility makes it a key material in multiple industries.
In terms of preparation process, hydrophilic silica is usually produced by gas-phase method. This method converts silicon tetrachloride, oxygen, and hydrogen into gas-phase silica through chemical reactions at high temperatures. The generated gas-phase silica particles are extremely fine, with characteristics such as porosity, non-toxic, odorless, and pollution-free. These characteristics make hydrophilic silica not only suitable for traditional industrial fields, but also show great potential in high-tech fields.
It is worth mentioning that hydrophilic silica also performs well in lubrication and thickening. For example, adding hydrophilic silica to lubricants can effectively reduce friction and wear between equipment, extending the service life of machinery. At the same time, its high adsorption performance makes it an ideal choice for thickeners, which can form a three-dimensional network structure by adsorbing liquids, improving the viscosity and viscosity of liquids.
With the advancement of technology and the continuous growth of industrial demand, the application fields of hydrophilic silica will continue to expand. Hydrophilic silica will also play an important role in fields such as environmental protection and new energy. For example, in areas such as oil-water separation and air purification, the efficient adsorption performance of hydrophilic silica will provide strong support for achieving green production.
In short, hydrophilic silica is becoming a shining star in the field of new materials due to its unique surface properties and wide range of applications. In the future, with the continuous innovation of technology and the expansion of applications, hydrophilic silica will bring revolutionary changes to more industries.
