Molecular sieve is the most aggressive of the primary desiccants in terms of absorption rate, and the most commonly used pore size for drying applications is 4 angstroms (4A).
Molecular sieve NaY, a kind of alkali silicon aluminate, is the Y type crystal Na molecular sieve. As is well-known that Molecular sieve NaY can adsorp molecules whose critical diameters are no greater than 10Å.
It is used for catalytic cracking catalyst preparation, drying dehydration, hydrogen desulfurization, the catalyst support,the purification of gases of oil refining and chemical industry, metallurgy, electronics and nuclear-related industries.
We are manufacturing Indicating silica gel & Non-Indicating type of SILICA GEL in all grades such as blue silica gel, orange silica gel and basic silica gel such as type A silica gel , type B silic gel ,type C silica gel and another special silica gel Column chromatography silica gel.
