Product Description

Molecular Sieve 13X, 5A, 4A, 3A, CMS, 13X APG, Insulating Glass Molecular Sieve, Carbon Molecular Sieve


Description:

Molecular sieve (as known as synthetic zeolite) is a micro-porous aluminosilicate crystals. It is made of silicon-oxy tetrahedron, alumina tetrahedron to form a basic skeleton structure, in which exist metal cations (e.g. Na+, K+, Ca2+, etc.) to balance the excess negative charge in the crystal. According to the type of crystal structure, zeolite consists of: A-type , X-type, Y-type and so on.
Adsorption: The adsorption capacity of molecular sieve comes from the physical adsorption (vander Waals force). The crystal has a strong polarity and coulomb field, which show a strong adsorption capacity for polar molecules (water) and unsaturated molecules.
Sieving: The pore size of molecular sieve distribution is very consistent. Only when molecular diameter is less than the pore size of molecular sieve, the molecule is possible adsorbed into the crystal cave. Distinguishing molecules of different substances by the priority of adsorption and the sizes, it is vividly called "molecular sieve".
A and X type zeolites
The special characteristics of molecular sieves include reversible adsorption of various gaseous compounds and a network of cavities and narrow pores giving very high internal surface area.
Type A zeolite with sodium cations has a pore width of 4 Å, and is called MS4A.
Replacement of sodium by calcium cations leads to 5 Å pores, and is called MS5A.
In the same way replacement of sodium by potassium leads to molecular sieve MS3A.
Zeolite of type X gives pores of 10 Å and the calcium type corresponds to MS13X.
