3A molecular sieve,China price supplier

Molecular Sieve type ￡o 3A ￡? the ideal formula is 0.4K ₂ O·0.6Na ₂ O·Al ₂ O ₃ ·2.0SiO ₂ ·4.5H ₂ O,.Its effective aperture is 3 eh, mainly used for absorbed water(the diameter of water molecules is about 2.8 eh), not adsorb any molecular diameter greater than the water and thus play a role in screening, With the adsorption rate was fast, regeneration frequency ,more crash-resistant, high strength and Strong anti-pollution ability, adsorption efficiency and long life for high-end sector of choice for high-precision dry moisture products, Control of the cavity insulating glass has long maintained at the dew point below -60 ??.

 

Key Words

l          Under the ultra-low humidity conditions,still offer high water adsorbption capacity,Effective control of environmental humidity

l          Have a choice of gas adsorption, only the absorption of a diameter less than 3 angstrom molecular, mainly for the absorption of water molecules
