4A molecular sieve

4AMS

Molecular sieve 4A, also called zeolite 4A or zeolith 4A, is one type of aluminosilicate crystal with average pores measuring of 4 angstrom (0.4 nm). Molecular with kinetic diameter larger than 4 angstrom will be adsorbed by zeolite 4A, otherwise be excluded.

Product Details

Features

  • 4A Molecular Sieve, has an effective pore opening of 4angstroms(0.4nm).
  • It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.
  • It is non-toxic, safe and reliable to human body, and has no adverse effects on ecosystem.

Chemical Molecular

Formula: Na2O·Al2O3·2SiO2·4.5H2O.   (SiO2 : Al2O3 ≈2).

Applications

1.Deep drying of air, natural gas, alkaline, refrigerants and other gases and liquids.

2.Static drying of pharmaceutical packaging, electronic components and perishable objects.

3.The preparation and purification of Air.

4.As a dehydrating agent in paint and fuel.
