3A/4A/5A/13X/XH Molecular Sieve Pellet for Gas Deep Drying
Technical Parameter:
3A Molecular Sieve, is an alkali metal alumina silicate. It is the potassium form of the type A crystal structure.It has an effective pore opening of about 3 angstroms(0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers.
4A Molecular Sieve, is an alkali alumina silicate. It is the sodium form of the type A crystal structure. It has an effective pore opening of about 4 angstroms(0.4nm). It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.
5A Molecular Sieve, is an alkali alumina silicate. It is the calcium form of the type A crystal structure.It has an effective pore opening of 5 angstroms(0.5nm). It will adsorb molecules with a kinetic diameter of less than 5 angstrom and exclude those larger.
13X Molecular Sieve, is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. It will adsorb molecules with a kinetic diameter of less than 10 Angstrom(1.0nm) and exclude those larger.
