The role of the molecular sieve drying

molecular sieve drying is a cubic lattice silicon aluminate compound, mainly composed of silicon aluminium by oxygen bridge connecting the empty skeleton structure, uniform in structure, there are a lot of aperture of concreted complete order, inner hole surface area is very big. In addition also contains electricity price lower metal ions and ionic radius is larger and combining state of water. Because the water molecules in the heated continuously losing, but crystal skeleton structure remains the same, has formed many of the same size of the cavity, the cavity has many of the same diameter pores is linked together, these small cavity diameter size uniform, can channel diameter smaller than the drying molecular sieve to the interior of the cavity, and the hole bigger than molecular excluded, so the molecules of different diameter size shape, the degree of different polarity molecules, the boiling point of different molecules, degree of saturation of different molecular separation, which have the function of the "screening" molecules, known as molecular sieve. Current molecular sieves in chemical industry, electronics, petrochemical, natural gas and other widely used in industry.
