Zeolites have a crystal structure and characteristics, the surface of the solid skeleton, internal cavities may play a role in the adsorbed molecules. It has interconnected pores between the cavities, the molecule through the pore. Since the crystalline nature of the cavity, Datong sieve, sieve pore size distribution is very uniform. Zeolite according to their size intracrystalline pore selective adsorption of molecules, that is molecules adsorbed molecules of a certain size to the exclusion of the larger species, thus aptly called molecular sieves. Buy 3A molecular sieve, welcome to Shanghai there are new! Shanghai Co., Ltd. is a new molecular sieve zeolite by a group of long-term commitment to production, application and development staff of investment composition, molecular sieves, it is a professional production of molecular sieve adsorbents manufacturing companies, Changzhi molecular sieve, sieve the company annual output of 2,500 tons. 3A molecular sieve can be used for dehydration of ethanol: ethanol molecule diameter is about 4.4A. The diameter of water molecules at about 2.8A. 3A-type synthetic zeolite pore size is 3A, so it can be used to make ethanol dehydration. Zeolite molecular sieve _ _ Jincheng new molecular sieve (View) by the Shanghai new molecular sieve Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is a professional engaged in "molecular sieves" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "new" brand has a good reputation.
