4A Zeolite Edit this entry is missing information bar, add relevant content to make entry more complete, but also the rapid escalation of crackers desiccant hurry to edit it! Aperture 4A molecular sieve 4A Foshan desiccant, adsorbed water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, does not adsorb any molecular diameter greater than 4A (including propane), selective adsorption of the water is higher than any Other molecules. Zeolite is one the largest amount of industrial varieties. Shanghai has a new molecular sieve - carbon molecular sieve reference parameter editing Formula: Na2O · Al2O3 · 2SiO2 · 9 / 2H2O Al ratio: SiO2 / Al2O3≈2 effective aperture: about 4 [2] index unit sphere strip specifications mm 0.5-1.0? 3-5 1.6 3.2 1.6-2.5 Water adsorption (25 ℃, RH50%)% wt ≥21.5 ≥21.5 ≥21.5 ≥21 ≥21 attrition rate% wt ≤0.2 ≤0.2 ≤0.2 ≤0.25 ≤0.25 bulk density g / ml 0.69 -0.75 ≥0.69 ≥0.69 ≥0.70 ≥0.65 compressive strength N / ≥30 ≥80 ≥40 ≥70 packaging moisture (575 ℃, 3 小时)% wt ≤1.5 ≤1.5 ≤1.5 ≤1.5 ≤1.5 methanol adsorption capacity mg / g ≤140 ≤140 ≤140 ≤140 ≤140 3 architecture Commentary editor Hebei Desiccant | Desiccant | new new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) strong, credible, in Shanghai's Songjiang District elemental industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the new molecular sieves, and you hand in hand into the brilliant, for a better future!
