Coarse silica gel for the milky white particles.
Divided into spherical (SG05) and block (SG06) two kinds.
Main component of SiO2. NH2O, insoluble in water and inorganic acid, soluble in hydrofluoric acid and caustic solution.
Its internal structure for 0.78 1.00 ml/g, entrance aperture 80-100 - a, specific surface area of 350-500 m2 / g.
This product is mainly used for drying all kinds of industrial gases such as air, oxygen, hydrogen, chlorine and organic gases, the adsorption of organic acids from the transformer oil and moisture, drug purification and separation of industrial fermentation process of macromolecular protein adsorption, adsorption polyvalent harmful elements in water, moisture and pets bedding items, catalyst carrier, is also the foundation of further processing fine silica gel series products of raw materials.
