Using silica sol as the main raw material and polyvinyl alcohol, polymer emulsion and other film-forming substances to make slurry, it is used for color inkjet printing paper coating. Nano-silica in the silica sol can form nano-pores on the surface, play a good role in color fixing, and improve the clarity of color patterns.

Cationic silica sol can be adsorbed on the surface of the paper during the manufacturing process of cellophane, which plays an anti-sticking isolation role and plays an important role in the process of manufacturing cellophane.

In addition, in the production of rayon and cellophane, silica sol is used as a binder to prevent adhesion and rolling between films; using silica sol and photosensitive liquid to process photosensitive paper can make the photosensitive paper surface smooth and the image clear. And increase the exposure range to make one-step imaging paper; Silica sol is used for the undercoat of printing paper, copy paper and offset printing, which can make the paper surface smooth, the image contrast is clear, and the contrast is good. After the surface of kraft paper and corrugated paper is treated with silica sol, it can improve the slip resistance of the paper, reduce the sliding during transportation and storage, and improve the temperature resistance and strength of paper products; in the manufacture of non-carbon carbon paper, silica sol is used to replace clay and talc. Powder and silica powder coating can make the color more vivid; plastic film and cellophane tend to be sticky in summer, such as treatment with a mixture of silica sol and glycerol monostearate, it can be solved satisfactorily.
