Appearance: milky white, semi-transparent spherical or granular.
Characteristics:
high adsorption capacity at high relative humidity, apply for control humidity and anti-condensation packaging.
Properties:
Type B silica gel belongs to an inorganic and an amorphous material, is a highly active adsorption material; non-toxic, odorless, chemically stable, won’t dissolve in any solvent except for alkali and hydrofluoric acid.
Making method:
is generally obtained by reaction of sodium silicate and sulfuric acid, then undergo the process of aging, acidic soaking, washing, surfactant treatment, first drying, sieve and secondary drying.
