What are the characteristics of silica sol products
Source:Dongying Yiming New Materials Co.,ltd
1.High adsorption: Under certain conditions, it has a certain adsorption effect on inorganic and organic substances.
2.Has a large specific surface area: the specific surface area is generally 250to300 square meters/g.
3.Good cohesiveness: add silica sol to some kind of fiber or granular material, then dry and solidify to form a hard gel structure, which will produce greater cohesiveness (generally about 46.7kg/cm2).
4. Good temperature resistance: Silica sol can generally withstand about 1600 °C.
5.Good hydrophilicity and oil repellency: can be diluted to any concentration with distilled water, and the stability increases with the increase of dilution. However, it can also produce hydrophobicity when added to organic matter or various metal ions.
6.Alkaline silica sol has "high dispersibility", "good wear resistance" and good "light transmission".
