Recently, in the field of materials science, hydrophobic fumed silica has become a focus of attention in many industries due to its unique properties, bringing new vitality and transformation to industrial development.
Hydrophobic silica is a type of silica with a specially treated surface that reacts with silane based chemical reagents to form a layer of hydrophobic molecules on its surface, exhibiting strong water resistance and hydrophobicity, and effectively reducing interactions with water. This modification endows it with a range of outstanding performance, shining in multiple fields.
In the photovoltaic industry, hydrophobic gas-phase silica has become the key to improving the quality of photovoltaic modules. As a key packaging material to ensure the reliable operation of photovoltaic modules, the performance of photovoltaic adhesive is crucial. The addition of hydrophobic silica significantly enhances the cross-linking network of photovoltaic adhesive, improves weather resistance and mechanical properties. Experiments have shown that with the increase of the amount of hydrophobic silica added, the tensile strength of photovoltaic adhesive shows an upward trend. Under high temperature and high humidity aging conditions, the decrease in tensile strength and elongation at break slows down, and the high temperature and high humidity yellowing resistance is also improved, greatly improving the reliability of photovoltaic adhesive in high temperature and high humidity environments, providing strong support for the efficient and long-term development of the photovoltaic industry.
The coating industry also benefits from the application of hydrophobic gas-phase silica. It has excellent thickening effect and can significantly increase viscosity in liquids, widely used in the field of coatings. Its good dispersibility can improve the dispersibility in polymer materials, oils, and organic solvents, avoiding material precipitation and separation. For example, in some coating production enterprises, the successful application of fumed silica in coatings has significantly improved the main performance indicators of the coatings. The scrub resistance of exterior wall coatings has increased from over 1000 to over 10000, and the artificial accelerated climate aging and artificial radiation exposure aging time have also been significantly prolonged. The bonding strength and hardness between the coating and the wall have also been significantly increased, and the surface self-cleaning ability has been improved.
In the field of cosmetics, hydrophobic fumed silica can be used to control the texture of powder products, avoid clumping, and enhance product stability, providing consumers with a better user experience.
At present, the global hydrophobic silica market is showing a good development trend. With the increasing demand for emerging technologies such as new energy vehicles and electronic packaging materials, their market size continues to expand. Many enterprises have increased their R&D investment to improve product quality and performance, in order to meet the needs of different industries.
Hydrophobic silica, as a high-performance nanomaterial, is leading technological innovation and development in multiple industries due to its unique properties and wide range of applications. In the future, with the continuous advancement of technology and further expansion of application fields, hydrophobic fumed silica is expected to create more miracles in the industrial field.
