Product Introduction:
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.
Xintao 4A Molecular Sieve, the pore size distribution is very uniform, has very good adsorption properties and good oil adhesion, and has a certain buffer alkalinity effect. 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).
