Coarse Pore Micro-bead Silica Gel

Properties

The appearance of coarse mesh microspheric silica gel is white

transparent or translucent form. Its interior structure is a uniform

micropore structure; the physical-chemical properties are stable;

thermal stability is good and mechanical strength is high. Its

average diameter is 8.0-12.0nm, specific heat is 0.92kJ/kg · C,

and thermal conductivity is 0.167kJ/mhr. °C.

Application

This product is used as the catalyst and catalyst carrier in some

important industrial production of melamine, aniline, o-toluidine,

vinyl acetate, phthalic anhydride, maleic anhydride, butadiene

rubber, acrylonitrile and other products. Also it is widely used

in the refined aromatic hydrocarbons removal of petrochemical

products. In addition, it can also be used for purification of

medicine, selective adsorption separation of organic gas and

liquid, and the removal of many harmful elements of the water

such as multivalence during the ion-exchange.
