4A molecular sieve pore diameter of 4A, adsorbed water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, does not adsorb to a diameter greater than 4A any molecule (including propane), the selective adsorption of water higher performance than any other molecules. Is the largest amount of industrial the molecular sieve varieties one.
, Molecular Formula: Na2O · Al2O3 · 2.0SiO2 · 4.5H2O
Third, the specific application:
The depth of the air, natural gas, paraffins, and the cooling agent gas and liquid drying; preparation and purification of argon; pharmaceutical packaging, electronic components and easy deterioration substance static drying. Paint, fuel, paint as a dehydrating agent.
Packaging: 30kg / package, aluminum foil bag vacuum packing
V. Notes:
Molecular sieve before use, should be prevented from the pre-adsorbed water, an organic gas or liquid, otherwise, should be renewable.
