Carbon molecular sieve nitrogen _ new molecular sieve (certified) _ new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is specialized in the "sieve" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Pan. Shanghai has a new synthetic zeolite molecular sieve having Ltd design, good thermal stability and acid resistance Shanghai 4a molecular sieve, has become an important chemical products molecular sieves can be used as adsorbents, catalysts and additives, such as washing, including 4A Zeolite is a porous aluminosilicate containing crystal-like compound, was the price of the overall structure of negatively charged molecular sieve, easy and cation exchange interactions occur without disrupting the internal structure, with good selectivity cation Shanghai 13x molecular sieve adsorption characteristics, but the anion poor absorption and exchange capabilities.
