The ultra-small particle size silica sol series products have a large specific surface area and strong reactivity because they have a particle size of 2-7 nm. They can be used with cationic surfactants and pulp fibers. It plays a very good role in retention and drainage and has become a widely used product in the paper industry.

The photosensitive paper is treated with a mixture of a silica sol and a photosensitive liquid to make the photographic paper surface smooth, the image is sharp, and the exposure range is increased. After the photographic paper is treated with a silica sol, its fixing effect can be increased. Silica sol can be used as a release agent in cellophane. The surface of kraft paper and corrugated paper treated with silica sol can improve the slip resistance of the paper, reduce the sliding in transportation and storage, and improve the moisture resistance of the paper.

Huihe S-small particle size silica sol and S-830, S-1430, SD-large particle size silica sol are the most favored products in the papermaking industry.

Electronic industry polishing

The elemental silica silica sol can be well used as an abrasive polishing material for electronic products, metals, glass, mirror ceramics, silicon wafers, semiconductor materials, etc. due to its good spherical structure, relatively hard texture and pure quality.
