4A zeolite as a detergent additive role is mainly exchange of calcium ions in the water used to produce demineralized desiccant, remove dirt and prevent redeposition. 4A Zeolite is currently applied on behalf of the largest builders of phosphorus and most mature product. 4A Zeolite replace sodium tripolyphosphate as detergent additives to solve the environmental pollution has a major role. 4A Zeolite forming agent can also be used soap, toothpaste friction agent. Shanghai Co. --4A new molecular sieve zeolite proportion Bronst acid Lewis acid is higher than the pure phase molecular sieve. DME for catalytic carbonylation of methyl acetate reaction Dalian desiccant system, BEA / MOR sample activity was significantly higher than that of pure phase BEA, MOR pure phase and mechanical mixing BEA / MOR phase. MOR 60 h of reaction pure phase and BEA / MOR catalyst co-crystallization heat loss show, BEA / MOR total amount far below the crystalline molecular sieve carbon molecular sieve MOR pure phase, and therefore have a stronger reaction stability. Charcoal desiccant, desiccant, there is a 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!
