Property
Large-aperture small-sphere silicon gel is in the form of white transparent or semi-transparent state; inside part has even small spherical structure with stable physical and chemical performance, good thermal stability and high mechanical intensity. Average aperture is 8.0-12.0nm, surface ratio is 300—600m2/g, aperture capacitance is 0.8—1.1ml/g, heat ratio 0.92KJ/kg．℃, thermal conductivity: 0.167KJ/m．hr．℃。
Purpose
Used as catalyzer and catalyzer carrier for producing melamine, benzene anhydrides, maleic anhydride, cis-1,4-polybutadiene rubber and acrylonitrile, as well as hydrocarbon-remove of petrochemical products, absorption and separation of organic air and liquid.
