Silica gel - glassy transparent or opaque grain oval, Spherical or irregular shape from colorless to dark color. In its structure, silica gel is a highly porous body formed by tiny spherical particles, chemical composition - silica SiO2 (silica). Technical dried silica gel is a silica porous structure with a highly developed internal surface. Depending on the form of technical silica grains and produce granular lump, but depending on the porosity, (the pore volume and specific surface of the pore density) - finely porous and large-pore.
IBC Technical silica obtained by reacting sodium silicate with sulfuric acid or aluminum sulphate containing free sulfuric acid, followed by washing and drying the resulting product.
Silica is used as an adsorbent for drying and purification of air and other gases or vapors, for the drying and clarification of certain liquids, as a carrier for catalysts and for other purposes. It is especially effective at high relative humidity (> 80%) for purification of various industrial oils, oil sludges, as a carrier for catalysts in the chemical industry.
