The effective pore size of 3A molecular sieve is 3 angstroms, which is mainly used to adsorb water. It does not adsorb any molecules with a diameter greater than 3 angstroms. According to the characteristics of industrial applications, the 3A molecular sieve produced by our company has a faster adsorption speed, more regeneration times, higher crushing strength and anti-pollution ability, which improves the utilization efficiency of 3A molecular sieve and extends the service life of 3A molecular sieve. It is a necessary desiccant for deep drying, refining and polymerization of gas and liquid phases in the petroleum and chemical industries.
