Molecular sieve is a crystallization of silicon aluminium salts,due to its uniform aperture and high surface, so has many excellent features:
1. Adsorb according to the size and shape of the different aperture, i.e. only adsorb those small apertures,which have sameer size and shape of the molecular sieve;
2. For small polarity molecules and unsaturated molecules, the higher the degree of saturation and polarity, the selective absorption is more stronger;
3. Strong water absorption, even at high temperature, low water content situation , they still have quite high absorption capacity.
It includes 3A Molecular sieve,4A Molecular sieve,5A Molecular sieve,10X Molecular sieve,13X Molecular sieve and copper sieve.It has Strong water absorption, even at high temperature, low water content situation , they still have quite high absorption capacity. It is widely used as drying agent and desiccant.
