Al Silica Gel
Properties
Al Silica gel is colorless or light yellow transparent or translucent spherical particles with chemical moleculer formula mSiO2.nAl2O3.xH2O. Stable chemical properties, non - combustion, insoluble in any solvent except strona bese and hvdrofluoric acid. Compered with the silica gel with fine holes, the adsorption capacity of low humidity is similar (such as RH=10%. RH=20%), but the adsorption capacity of high humidity (such as RH=80%,RH=90%) is 6-10% higher than that of the silica gel with fine holes, and the thermal stablity(350ºC) is more than 150ºC higher than that of the silica gel with fine holes, so it is very suitable to be used as the variablle termperature adsorption and separation agent.
Application
It is mainly used for the adsorption and separation of light hydrocarbons by dehydration of natural gas. It can also be used as catalyst and catalyst carrier in petroleum industry. Industrial desiccant liquid adsorbent and gas separation.

Blue Silica Gel
Properties
Blue silica gel is blue or light blue glassy particles, The products are divided into blue silica gel indicator and blue silica gel.It is characterized by the hygroscopicity process, with the increase of hygroscopicity into purple, and finally into light pink, Can indicate the humidity of the environment can also be directly displayed whether the need to replace a new desiccant, It can be used as desiccant alone, can also be used with Type A Silica Gel.
Application
It is mainly used for absorbing moisture anti-rusting of instruments, gauges and
equipment in the enclosed conditions. After absorbing moisture, it turns from blue to red, visually i indicating the rel ative humidity of the given environments.When being used with ordinary sili ca gel or drier,it indicates to which extent the drier absorbs the moisture and j udges the relative humidity of a given environment. It is widely used as silica gel drier for the packing of precision instruments,leathers,shoes,clothes,foodstuffs,medicines and household electric appliances, etc.
