Description

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, ***** 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. Its main types are 3A、4A、5A、*0X、*3X and copper sieve etc.
