3A Molecular Sieve

3A molecular sieve is a potassium-sodium type aluminosilicate, it is exchanged with Kfor the Na+ of 4A molecular sieve to form a pore size of 3A molecular sieve, which is mainly used to adsorb water and not adsorb any molecule with a diameter larger than 3Å. According to the characteristics of industrial application, the Howay molecular sieves have faster adsorption speed, more regeneration times, higher anti-crushing strength and anti-pollution ability, which improves the utilization efficiency of molecular sieve and prolongs the service lifetime of molecular sieve, it’s the preferred desiccant necessary for deep drying, refining and polymerization of gas and liquid in the petroleum and chemical industries.
