Product Description

Colloidal silica are suspensions of fine amorphous, nonporous, and typically spherical silica particles in a liquid phase. It may be produced by Stöber process from Tetraethyl orthosilicate (TEOS).

Production Usage

1.Used as the cohesive agent for various fireproof materials. It has high bonding strength and high heat-resisting performance (1500-1600ºC ), etc.

2.Used in coating industry. It makes the paints firm. It also possesses features, such as anti-contamination, dust proof, anti-aging, fireproof, etc.

3.Used in precision casting of thin covers to increase the cover strength, inprove the casting smooth finish. Its molding quality is better than that of water glass. It can be used to replace ethyl silicate for molding so as to reduce the costs and help improve the operating conditions.

4.Having large specific surface area, silica sol can be use for making catalyst and as catalyst carrier.
5.Used in paper-making industry. Can be used as the anti-glutinous agent of cellophane, pre-treatment agent of photographic paper, skid proof agent of cement bags, etc.

6.Used as sizing agent in textile industry. When used with oil agent to process wool and rabbit hair, it helps improve the processing of wool and rabbit hair, reduce broken ends, eliminate flyings, thus improve the finished product rate and increase the economic returns.

7.Used as the treatment agent of silicon steel plates, dispersing agent of kinescopes and skidproof agent of floor waxes, etc.
