Adsorption function: molecular sieve xh-11 of matter from the physical adsorption (van der Waals force), the crystal inside the cavity has a strong polarity and coulomb field, the polar molecules (water) and unsaturated molecules exhibit strong adsorption ability.
Sieving function: double glazing molecular sieve pore size distribution is very uniform, only the molecular diameter smaller than the diameter of the cavity material made it into the zeolite crystal inside the cave.
Through adsorption priorities and the size to distinguish between different materials of molecules, so the image of a called "molecular sieve".
