4A Zeolite Edit this entry is missing information bar, add relevant content to make entry more complete molecular sieve Shanghai, but also the rapid escalation, hurry to edit it! Aperture 4A molecular sieve 4A molecular sieve characteristics, Shenyang 3a molecular sieves adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, molecular sieve, does not adsorb any molecular diameter greater than 4A (including propane), selective adsorption of water performance than any other molecules. Zeolite is one the largest amount of industrial varieties. Shanghai new sieve -4A sieve molecular sieve is a synthetic, cubic lattice having microporous aluminosilicate. Depending on the size of its internal cavities of the crystal and molecular adsorption or exclusion of different substances, which is called "molecular sieve." Substance molecular sieve crystals smaller diameter than the diameter of the pore molecules can enter the molecular sieve crystals, so as to be adsorbed, otherwise excluded. 13x molecular sieve zeolite manufacturers _ _ 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!
