Molecular sieve is high performance adsorbent with excellent kinetic gas adsorption and separation capacity. Moleular sieve is widely used in various industries such as air separation, oxygen generator, hydrogen purification, natural gas dehydration, ethanol dehydration, ethylene dehydration, propylene dehydration, refrigerant dehydration, air break system etc.
Synthetic zeolite powder is crystal aluminosilicates with defined three-dimensional pores of molecules size, such as water,and . Molecules smaller than pore diameter can be adsorbed while the larger ones are excluded. Thus zeolite powder is usually made into molecular sieve adsorbent to separate different molecules of different sizes. Type A and X are two typical structures of zeolite powder.
Molecular sieve powder is activated zeolite powder. Activated molecular sieve powder has excellent moisture adsorption capacity. In polyurethane system, zinc-rich coating, painting, sealant and adhesive production and application, it works as moisture scavenger to remove water and other contaminant contained in solvents and additives to improve product quality and extend pot life.
