According to the order of the molecular sieve preferentially adsorbed polar molecules of different substances decision. According to the size and shape of the molecule adsorption of different choices, that is, only those molecules smaller than the molecular sieve adsorption pore. For small polar molecules and unsaturated molecules having selective adsorption properties of the desiccant shoe, the greater the polarity, the higher the degree of unsaturation, the stronger its selective adsorption. A zeolite molecular sieves which are a desiccant, is very similar to the structure of NaCl, belonging to the cubic system. Shanghai has a new molecular sieve - from sewage metal mines, smelters, metal surface treatment and chemical emissions from industry and other sectors, which contains heavy metal ions harmful to human health. 4A molecular sieves with sewage in addition to those qualified to ensure the quality of foreign purchases of desiccant, but also the recovery of heavy metals. Other uses (1) water ---- water softener custom desiccant can replace the current widespread use of sulfonated coal, thereby reducing costs; (2) Metallurgical Industry ---- separating agent, separation, extraction brines potassium, rubidium, and cesium. In industry for the enrichment, separation and extraction of metals and other processes; (3) ---- catalyst petrochemical industry, desiccants, adsorbents; (4) ---- agricultural soil conditioner; (5) Pharmaceutical - --- silver zeolite antimicrobial agent. 6 packaging and storing lined with two layers of polyethylene plastic editor of plastic woven bag, net weight 25kg. Stored in a ventilated, dry coffers. Pay attention to moisture, prevent rain custom desiccant, desiccant transportation, 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!
