Wide application of silica sol

The ion exchange process of silica sol is the most mature and widely used process. This process has certain requirements on materials such as water glass and ion exchange resin and the operation process. Silica sol is a colloidal solution, odorless, non-toxic, and has the following properties:

1. Because the colloidal particles are fine and have a relatively large specific surface area, the particles themselves are colorless and transparent, and do not affect the true color of the covered object.

2. The viscosity is low, and the place where water can penetrate can penetrate, so the dispersibility and permeability are very good when mixed with other substances.

3. When the silica sol water evaporates, the colloidal particles firmly adhere to the surface of the object, and the silicon-oxygen bond is formed between the particles, which is a good adhesive
