Shanghai has a new molecular sieve welcome you! 3A molecular sieves are mainly used: unsaturated hydrocarbon materials, such as ethylene, propylene, butadiene, cracked gas drying, etc., to effectively prevent the hydrocarbon co-adsorption. Dry polar liquids (such as methanol, ethanol, organic hydroxy compound). Dry refrigerant. Ammonia Industry in nitrogen - hydrogen gas mixture to dry. Food grade CO2 drying. Shanghai Co., Ltd. is a new molecular sieve zeolite by a group of long-term commitment to the production, application and development of personnel investment composition, is a professional production of molecular sieve adsorbents manufacturing enterprises, the company annual output of 2,500 tons of various types of molecular sieve. The company established a strict quality management system, has passed ISO9001: 2008 international quality management system certification. 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." Molecular diameter less than the diameter of the pore molecular sieve crystals can enter the substance produced zeolite molecular sieve crystals, so as to be adsorbed, otherwise excluded. Zeolite also decided to order preferentially adsorbed molecules, depending on the polarity of the material. According to the size and shape of the molecules of different options sieve adsorption of hydrogen, that is, only those molecules smaller than the molecular sieve adsorption pore. For small polar molecules and unsaturated molecules having selective adsorption properties, the greater the polarity of the molecular sieve, the molecular sieve index higher degree of unsaturation, that selects the stronger adsorption. A zeolite molecular sieves are one of them, which is very similar to the structure of NaCl, belonging to the cubic system. Because of the effective aperture of 4A Zeolite 0.4nm, it is known as 4A molecular sieve network structure composed of silicon-oxygen tetrahedron unit [SiO4] and aluminum-oxygen tetrahedron [AlO4] unit staggered from. Refrigeration sieve sieve _ _ 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!
