Type A silica gel is a transparent or translucent particle with the chemical formula mSiO2.nH2O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid, and strong caustic soda solutions. This silica gel boasts high mechanical strength, good wear resistance, an average pore diameter of 2.0-3.0nm, surface area of 650-800m2/g, and pore volume of 0.35-0.45ml/g.
Primarily used for drying and moistureproof, Type A silica gel can also serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.

Properties: Al Silica gel is colorless or light yellow transparent or translucent spherical particles with a chemical molecular formula mSiO2.nAl2O3.xH2O. It has stable chemical properties, is non-combustible, and insoluble in any solvent except strona bese and hydrofluoric acid. Compared with silica gel with fine holes, it has similar adsorption capacity at low humidity (e.g., RH=10%, RH=20%), but 6-10% higher adsorption capacity at high humidity (e.g., RH=80%, RH=90%). Its thermal stability (350ºC) is more than 150ºC higher than silica gel with fine holes, making it suitable for variable temperature adsorption and separation.
Application: Al Silica Gel is mainly used for the adsorption and separation of light hydrocarbons by dehydration of natural gas. It can also serve as a catalyst and catalyst carrier in the petroleum industry, industrial desiccant liquid adsorbent, and gas separation.

Blue Silica Gel Beads for Water Absorption in 20kg or 500kg bags by Lianyungang Chemsize International Trading Co., Ltd.
Blue silica gel consists of blue or light blue glassy particles. The product is available as blue silica gel indicator and blue silica gel. It exhibits hygroscopic properties, changing from blue to purple and eventually to light pink as it absorbs moisture. This color change indicates the humidity level of the environment and signals when replacement is needed. Blue silica gel can be used independently as a desiccant or in conjunction with Type A Silica Gel.
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment kept in enclosed conditions. As it absorbs moisture, it transitions from blue to red, visually indicating the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps assess the moisture absorption capacity of the drier and determine the relative humidity of the surroundings. This versatile product is commonly employed as a silica gel drier for packaging precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.
