Coarse Kong Wei ball silica gel for the milky white spherical particles.
Main component of SiO2. NH2O, insoluble in water and inorganic acid, soluble in hydrofluoric acid and caustic solution.
High mechanical strength, good abrasion resistance.
Its internal structure for 0.80 1.10 ml/g, entrance aperture 80-120 - a, specific surface area of 350-460 m2 / g.
This product is mainly used for phthalic anhydride, aniline and maleic anhydride, three poly acrylic important petrochemical products such as ammonia, acrylonitrile catalyst and catalyst carrier, also widely used in refined oil products, for some selective adsorption separation of organic gas and liquid components.
Polyvalent also can be used as in drinking water, the ion exchanger of harmful elements.
And for material, equipment and other goods dry after water storage and high purity gas refining.
