SiO2 Granular as Anti Clumping Agent for Animal Feed
Silica (chemical formula: SiO2) is an acidic oxide hydrate, corresponding silicate (H2SiO3). Silica insoluble in water, insoluble in acids, but soluble in hydrofluoric acid and hot concentrated phosphoric acid, capable of acting with molten bases. There are two kinds of crystalline silica and amorphous silica in nature. Silica is widely used, mainly for the manufacture of glass, water glass, pottery, enamel and refractory materials.
Silica will significantly reduce the tendency to agglomerate and improve flow properties.
As the flow resistance agent, the silica particles with relatively small particle size and low added amount; the silica particles used as the carrier have relatively large particle size and can reach more than percent adsorption.
