Silica gel (Silica gel; Silica) Alias: silicone elastic is a awful alive adsorption actual is baggy material, its actinic blueprint for mSiO2 · nH2O. Insoluble in baptize and any solvent, non-toxic, tasteless, chemically stable, in accession to alkali, hydrofluoric acerbic does not acknowledge with any substance. Various types of silica because of their altered accomplishment methods and the accumulation of altered pore structure. The silicone actinic apparatus and concrete structure, it difficult to alter abounding added agnate actual characteristics: top adsorption properties, acceptable thermal stability, actinic stability, top automated strength. Silicone is disconnected according to the admeasurement of the aperture: macroporous silica gel, base silica gel, B blazon silica gel pore silica gel.
The silica gel can be acclimated as a desiccant, and can be reused. Silica is a silicic acerbic gel mSiO2 · nH2O adapted dehydrated particles of altered sizes fabricated of a absorptive substance. Having an accessible absorptive anatomy of ample specific apparent (surface breadth per mass), able of adsorbing abounding substances, is a acceptable desiccants, adsorbents and agitator carriers. Silica gel adsorption mainly concrete adsorption, can be regenerated and acclimated repeatedly. The accession of acerbic in the acrid metal silicate band-aid (such as sodium silicate), acidified, and again a assertive bulk of electrolyte is added and stirred, which accomplish silicic acerbic gel; abacus acerbic or sodium silicate band-aid in a darker or The ammonium alkali can aswell accomplish silicic acerbic gel.
