Parameters of fumed silicon dioxide hydrophobic / Porous silicon dioxide nanoparticles

Silicon dioxide is a non-toxic and environmentally friendly material that is widely used in the manufacturing of a variety of products, including electronic components, optical devices, and sensors. However, Silicon dioxide has a strong tendency to become water-dense when it comes into contact with water, making it difficult to recycle or reuse.
To overcome this problem, researchers have developed a new technology that uses suspended particles made up of porous SiO2 instead of traditional colloidal silicon dioxide. This new technology uses a process called electrophoresis, which involves passing a concentrated solution through a series of semiive columns.
When the particles are passed through the column, they gain energy through the collisions between them and the surface of the column. The energy generated by the collisions is then transferred back to the particle, increasing its density and leading to better recycling efficiency.
By using Porous Silicon dioxide Nanoparticles instead of traditional colloidal dioxide, researchers can significantly reduce the amount of water needed to recover SiO2 from. This could lead to increased recycling rates and reduced environmental impact.
Overall, this new technology holds great promise for solving the water-dense problem associated with Silicon dioxide production. By reducing the amount of water required to recover SiO2, it could help to improve the sustainability of theSiO2 industry and create a more efficient and environmentally-friendly manufacturing process.
