(1). Silica gel.

　　Silica gel is a kind of highly active adsorption material. Its chemical molecular formula is SiO₂.nH₂O.It is insoluble in water and any other solvent, It is nontoxic, tasteless and chemically stable.

　　According to the different pore diameters of silica gel, they are categorized into Fine-pored silica gel(Type A); Type B silica gel; Macro-pored silica gel(Type C) and Large-pored silica gel.

　　Silica gel is used as drier, adsorbent and catalyst carrier.


(2)Silica sol.

　　Silica sol is a kind of colloid, it is odorless and nontoxic. Its chemical molecular formula is mSiO₂.nH₂O. Silica sol has relatively large specific surface area, it is colorless and transparent. It has high bonding strength and high heat-resisting performance(1500-1600℃).

　　Silica sol can be used as the cohesive agent for various fireproof materials and used for making catalyst and as catalyst carrier; used in coating industry; in paper-making industry and so on.

(3)Silica gel FNG.

　　This is a kind of silica gel which is processed and formed from powders, it is white or light gray. Besides the adsorption feature possessed by ordinary silica gel, FNG silica gel possesses good water-tolerant property, low break-down rate of reclamation and long service life.

　　Silica gel FNG is mainly used for air drying in the air separating process, drying compressed air and various industrial gases. In petrochemical industry, electric power industry, brewing industry, it is used as liquid adsorbent and catalyst carrier.

(4)Macro-pored Micro-spherical Silica gel.

　　Macro-pored Micro-spherical Silica gel has well-distributed micro-pored structure, good thermal stability and high mechanical strength.Its sizes from 50 to 850 Micron.

　　This product can be used as catalyst or catalyst carrier.It may also be used for the selectivly adsorptive separation of organic gases and liquids, as well as for eliminating multivalent poisonous elements in water through ion exchanging process.
