Nouryon-諾力昂 Levasil FO830 Colloidal silica水性納米二氧化矽分(fèn)散液(yè)

Levasil FO830 is an alkaline, aqueous dispersion of colloidal silica that is approximately 30% solids by weight. The silica dispersion is sodium stabilized and the amorphous silica particles carry a negative surface charge. The silica particles are discrete, have a slightly rough, spherical shape, and are present in a narrow particle size distribution. The physical appearance of the dispersion is a translucent liquid, slightly more viscous than water. Levasil FO830 is produced for world-wide distribution.

Applications
Levasil FO830 is an excellent binder with very high binding power for a broad variety of inorganic materials as refractories.

 

Storage
Levasil FO830 should be transported and stored at a temperature of 5-35°C (40-95ºF). If the silica dispersion is allowed to
freeze, the silica will irreversably precipitate. For bulk storage, the tank should be sealed and constructed of plastic,
fiberglass reinforced plastic, or stainless steel. For packaged goods, any translucent packages should be stored out of
direct sunlight or bright light. Under recommended conditions, Levasil FO830 has a shelf life of at least twelve months
after production.

 

Packaging and transport
Levasil FO830 is available in bulk and packaged quantities. Bulk shipping and packaging sizes can vary by region.
