Macroporous microsphere silica gel
[character]
The product is white transparent or translucent in appearance, with uniform microporous structure inside, stable physical and chemical properties, good thermal stability and high mechanical strength. The average pore diameter is 8.0-12.0nm, specific surface is 300-600㎡/g, pore volume is 0.8-1.1ml/g, specific heat is 0.92kj/kg.℃, thermal conductivity is 0.167kj/m.hr.℃.
[purpose]
This product is used as catalyst and catalyst carrier in the production of melamine, phthalic anhydride, maleic anhydride, cis-1,4-polybutadiene rubber, acrylonitrile and other important industrial products. It is also widely used in the refining of petrochemical products to remove aromatics. It can also be used in the selective adsorption and separation of organic gases and liquids and the removal of multivalent harmful elements in water by example exchange.
